A fascinating new study reveals that giant free-floating planets, known as rogue planets, may have the ability to form their own miniature planetary systems independently of a host star. Observations from the Webb Space Telescope have identified young rogue planets with masses between 5 to 10 times that of Jupiter. These dim objects, which emit primarily in the infrared spectrum, are believed to hold secrets about the formation of planetary systems. The findings indicate that disks of warm dust surrounding these planets could provide the necessary materials for planet formation, suggesting that such systems could exist even in the absence of stars.Europe's Space Rider Progresses
The European Space Agency's reusable Space Rider spacecraft has successfully completed a crucial test of its nose cone, marking another milestone in its development. This innovative spacecraft will allow ESA to conduct orbital missions and return scientific payloads to Earth. Designed to operate as an unmanned laboratory in low Earth orbit, Space Rider will support a variety of experiments and technology demonstrations, paving the way for Europe to enhance its capabilities in space exploration.Harvesting Solar Power from Space
Could space-based solar panels be the solution to our energy needs? Scientists are investigating two promising projects aimed at capturing solar energy in orbit. The Innovative Heliostat Swarm aims to create a network of mirrors that direct sunlight to a central receiver, converting it into electricity for transmission back to Earth. Meanwhile, the Mature Planar Array is closer to deployment but will only capture solar energy about 60% of the time. Despite current challenges in cost-effectiveness, these projects could lead to breakthroughs in sustainable energy.www.spacetimewithstuartgary.com

This is Spacetime Series twenty eight, episode one hundred and four,
for broadcast in the twenty ninth of August twenty twenty five.
Coming up on Spacetime, claims that giant free floating planets
may form their own planetary systems, europe Space Writer spacecraft
completes another key test, and could we use space based
solar panels to power the Earth? All that and more
(00:23):
coming up on Spacetime.
Speaker 2 (00:26):
Welcome to space Time with Stewart Gary.
Speaker 1 (00:45):
A new study has found that giant, free floating so
called rogue planets, have the potential to form their own
miniature planetary systems without the need of a heart star.
The findings reported on the pre press physics website archive
dot org, based on observations on the web space Telescope
looking at young, isolated objects with masses of five to
ten times that of Jupiter. These objects are comparable to
(01:07):
gas giants in their properties, but are free floating in space,
not bound to any host star as Jupiter is to
the Sun. Free floating planets are difficult to observe because
they're very dim and they're raady it mostly in the infrared,
but they hold keys to important questions about astrophysics. Current
research suggests that these may will be the lowest mass
objects formed like stars from the collapse of molecular gas
(01:30):
and dust clouds, but in contrast to stars, they don't
accumulate enough mass to trigger the core nuclear fusion process
which makes stars shine. Now in theory, it's also possible
that some of these may have formed in a way
comparable to how planets form through the accumulation of material
around the star, but they were later ejected from their
home system some sort of gravitational perturbation. To work out
(01:52):
what's going on, scientists observed eight of these objects, all
very young, in order to learn more about their infancy.
They use two instruments able the web Space telescope to
obtain detail at infrared spectroscopic observations of these objects over
a period of three months. Six of these objects have
excess emissions in the infrared caused by warm dust in
their immediate vicinity, and that's important because that's a characteristic
(02:15):
signature of disks, which are often the birthplaces of planets.
The observations also showed emission lines for silicon grains in
the disks. That's a clear sign of dust growth and
crystallization and typically the first steps in the formation of
rocky planets. Now, silicon emissions have been found for stars
and brown dwarfs before, but this is the first detection
(02:36):
in a planetary mass object. One of the studies authors,
Alex Schultz, from the University of s and Andrews, says
the new findings built on previous work showing that discs
around free floating planetary mass objects can last several million years,
which is plenty of time to form planets. Schultz says
that taken together, these studies showed that objects with masses
comparable with those of gas giants have the potential to
(02:58):
form their own miniature planetary system, and those systems could
be like our solar system, just scaled down by a
factor of one hundred or more in size. These new
discoveries show that the building blocks needed for forming planets
can be found even around objects that are barely larger
than Jupiter and drifting alone in the darkness of space.
It means that the formation of planetary systems is not
(03:19):
exclusive to stars and brown dwarves, but may also work
around lonely starleus worlds as well. But whether or not
such planetary systems actually exist. Still remains to be seen.
This is space time Still to come. The European Space
Agency's reusable star Writer spacecraft completes another key test and
could we use space based solar panels to power the Earth?
(03:43):
All that and more still to come on space time.
The European Space Agency's Usable Space Rider has just completed
(04:05):
the latest phase of its development campaign with a successful
qualification test of the vehicle's nose cone, the largest single
component of the spacecraft's thermal protection system. This latest mission
followed a successful qualification test of the vehicle's body flaps
back in February. Once operational, Space Rider will provide ASO
with its first orbital return to Earth and landing capability.
(04:27):
The wet shaped lifting body designed spacecraft will be launched
a bought a Vagas Sea rocket into low Earth orbit.
It will be capable of carrying payloads of up to
eight hundred kilograms. Once in space, it'll operate as an
unmanned laboratory for periods of over two months. The payload
bay is environmentally controlled and provide services including six hundred
WTTs of power for experiments, along with thermal control, data
(04:49):
handling and telemetry capabilities. It'll then re enter oath atmosphere
and land using parasales, returning their payloads to eager engineers
and scientists, and after minimal refe furbishment, should be ready
for its next mission with new payloads. This is Director
of Space Transportation Daniel Neinstringer. So Space Rider missions will
offer an array of altitudes and inclinations, enabling a variety
(05:12):
of experiments in microgravity, as well as technologies for Earth observation, science,
telecommunications and robotic exploration.
Speaker 3 (05:20):
It's a fact that today Europe does not have this capacity.
It is also a fact that if corresponding decisions are
taken at the end of the year, Europe will have
it tomorrow. And in fact, at EZA we had already
a technology demonstration of a re entry on Earth which
took place a few years ago in an experimental vehicle
(05:41):
called IXV, and based on this experience, which was highly
successful and launched by Vega by the way, we are
now developing Space Rider. During a low Earth orbit operation
in microgravity, the vehicle can turn a maneuver according to
the mission it has. Then at the moment in time
(06:02):
you start the re entry on Earth. In fact, you
have a dedicated angle of attack, you start to enter
into the atmosphere and this is what we call a
lifting body, meaning there are no plane type of structures.
It's just the body which has a certain angle of attack,
(06:22):
enters into the upper part of the atmosphere at high speed.
We call it hypersonic and then the speed is decreased
through the drag and when it starts to become subsonic,
you have lowered significantly the speed and once you have
reached a certain level you can deploy a parafoil and
once with a parafoil deployed, you can have a precision
(06:44):
landing on a runway somewhere in your We do a
call for opportunities and we will have a different flight
opportunities plan, for example in microgravity research, so if you're
coming from a university, that's for sure an opportunity, like
in material sciences or pharmaceutical field, biological fee at large scale. Second,
(07:09):
we will work on commercial opportunities and here we have
already quite good exchanges again with the pharmaceutical industry, and
we will look for further in orbit validation and demonstration
of technologies which have to be tested and qualified in
space before they go on big and cost emissions.
Speaker 1 (07:31):
That'ss's Director of Space Transportation, Daniel no Insrender and that
report was on ATV. This is space time, Still the calm.
Could we use space based solar panels power the Earth?
And Later in the science report, a new study shows
that dogs are more likely to react to onscreened animal
characters on TV anti human TV characters. All that and more,
(07:53):
Still the calm on space time. Okay, let's take a
break from our show for a work from our sponsor
Into three sixty, The Trailblazers in three sixty in action
cameras pushing the boundaries of what's possible or creators everywhere.
Last week, Into three sixty dropped their lettuce game changer,
(08:16):
the Go Ultra, a pocket size camera that's reader finding
how you capture life's adventures. Imagine it a camera no
bigger than an oro, weighing just fifty three grams, yet
packed with a power to shoot buttery smooth four K
video at sixty frames per second. It's small enough to
slip into your pocket, but the liver's professional grade footage
(08:36):
that'll make your vlogs, travel diaries, or family moments look
absolutely stunning. The standalone camera is the IPX eight waterproof
up to thirty three feet, so it's ready to roll
whether you're surfing, swimming, or caught in the rain. And
the Go ultras upgraded center and AI chip ensures your
shots are always crisp and vibrant. Day or night. Low
(08:57):
light scenes no problem. The Pure Video uses AI to
reduce noise and boost dynamic range, so your nighttime adventures
also shine. And here's the best part. For the first
thirty Spacetime listeners who purchase the Inster three sixty Go
Ultra at store dot Instero three sixty dot com, your

So don't miss out on this titan of a camera
that's real to capture your world like never before. That's
the Insta three sixty Go Ultra and now it's back
(09:40):
to our show. Well it may sound futuristic, but cydists
believe that space s based solar panels could eventually allow
humans to harvest energy from the sun almost continuously at
any moment of the day. The big problem with solar
panels and win turbines, of course, is that they don't
(10:02):
provide reliable electricity. That's because the sun doesn't shine all
the time and the wind doesn't blow continuously. Also, with
wind turbines, their carbon footprints greatly exceed the amount of
carbon they save, and both of the ongoing problem of
what to do with them when they wear out in
twenty years time. And that's why scientists engineers are looking
at alternatives, and one of them involved two space based
(10:25):
projects put solar panels in orbit. The first of the
two projects, named the innovative helio stats SWARM, is in
the early development but is the most likely to be
able to continuously capture solar energy. It's a space based
solar power concept involving a large array of mirror like
reflectors or helio stats in space that directs sunlight to
a central receiver, converting it into electricity, and then transmitting
(10:47):
it wirelessly down to worth, likely using either microwaves or
laser technology. The designing corporates innovations like retrodirective RF transmission arrays,
highly efficient PV cells, and modulustres. Overall, the model estimates
that the heliostat design will reduce total system costs by
about seven to fifteen percent, offset up to eighty percent
(11:08):
of wind and solar, and reduced battery usage but over
seventy percent. The second concept is named the mature planar array,
and it's much closer to being ready, but it will
only capture solar energy around sixty percent of the time. Still,
it's a big step from solar panels based on Earth.
The array uses an arrangement of solar antenna elements in
(11:29):
a flat rectangular grid, similar to those already used by
satellites and space stations, so we know it's going to
be reliable microwave or infrared emitters within the US to
transmit that energy data Earth. But a report in the
journal Dual warns that both current designs are still not
yet cost effective. Nevertheless, scientists hope the two systems can
(11:49):
be earned were to help with Earth's future net zero needs.
This is space time and time that told. Take another
(12:13):
brief look at some of the other stories making us
in science this week with the Science Report. A new
study claims that diets rich in a Mega three fatty
acids w you're found predominantly in fish may help board
off short sightedness in kids. Meanwhile, a high intake of
saturated fats found in foods such as butter, palme oil,
and red meat may increase the risk of short sightedness.
(12:33):
A report in the British Journal of Ophthalmology looked at
the eyesight of around a thousand children and compared the
development of our conditions against the results of a food
frequency questionnaire. They also asked how much time the kids
spent outdoors, how much time they spent reading and writing,
and how much time they spent on screens. The authors
found that the quarter of kids will consumed the least
amount of Amiga three fatty acids also had the largest
(12:55):
markers for the progression of short sightedness I. Meanwhile, the
quarter of children who had the highest intake of Amega
three fatty acids had the smallest incidents of the condition,
and they also found the inverse to be true for
kids who consume the highest intake of saturated fats. A
new study has shown that while fans can help keep
your cool in hot temperatures, in really dry hot temperatures
(13:18):
they'll actually make things worse. A reporting the Journal of
the American Medical Association subjected fifty eight people to various
three hour heat exposure tests, looking at how temperature and
humidity impacted the effectiveness of a fan or wetting the
skin or reducing body temperature and discomfort. The authors say
that in thirty eight degrees celsius heat with sixty percent humidity,
(13:38):
fan use margially improved body temperature and participants reported feeling
less warm. But in forty five degrees celsius dry heat,
they found that using a fan actually increased the participant's
body temperature as well as sweating, and made them feel
far more uncomfortable. A new study is shown that dogs
are more likely to react to on screen animal characters
(13:59):
than humans or other objects displayed on TV. The findings,
published in the journal Scientific Reports, examine the reactions of
four hundred and fifty puppies. The dogs reported as excitable
by their owners were more likely to follow on screen
animals as if they were real, while fearful or anxious
dogs were more likely to respond to stimulis such as
cars or a doorbell. The authors warn their findings may
(14:20):
not apply to all dogs, as the survey respondents were
all pet owners whose dogs regularly interacted with TV stimuli
and time now for our silliest story of the week,
and it seems there's a new contender for the title
of Britain's most haunted pub. The owner of the year
Oldie King's Head Hotel in Chester claims he's experienced bedcovers
wrapping tightly around him all by themselves, strange knocking noises,
(14:43):
and the sounds of ghostly children running down the hallway
to mend them from the strange skeptic says it's worth
pointing out the owner is developing a TV series based
on his claims.
Speaker 4 (14:53):
Through the hotel in Chester called The Oldie King's Hits,
which is the most haunted hotel in England, if not Britain.
They all, there's a lot of most haunted buildings in
the UK. Whatever saw it, and this one is one
that's had been around for a while. So the old
old pub that someone brought has did it up a bit,
and now suddenly there's all these sort of hauntings happening
from a more sort of ghost here than there is
(15:15):
any other haunted hotel. Roman warriors, Civil war soldiers, women
and children running up and down the corridors when it
was used as a brothel. Apparently, so it sounds exciting
this fellow who's bought it recently and renovated. There's now
put cameras in every room, which is a worry if
you want to stay there, Yes, and I think I
want to stay there someone watching me. Apparently people don't
stay there very long. They all go running away screaming
(15:36):
because it's a haunted place. But of course you have
to also keep in mind that this is a fellow
who hosts a podcast called My Haunted Project. He has
several properties and this Haunted Project is focused on quote
changing the paranormal and evolving it to a new level
based on real evidence I witness accounts in twenty four
to seven surveillance. He also has the whole range of
different displays, including the Great Dole, which is the haunted
(15:59):
or sort of cursed Dole, much like the Doll in
the US, much the same sort of thing, has her
own room. It's been a special glass case said to
be the UK's most haunted artifact. He's got a prime
video program called My Haunted Hotel series which features is
the Oldie King's Head pub he certainly has some money
in this that he wants this to be true. Whether
he really believes in it, there's certainly promotion. It's one
(16:21):
of the sad things that these days, so many groups,
so many buildings, so many organizations, are putting up their
premises for ghost to it.
Speaker 1 (16:28):
I was going to say he's got some competition because
just about every hotel in the UK is said to
be haunted.
Speaker 4 (16:33):
Yeah, every pub, every ancient castle, every you know what.
The same in the same in America as so many places.
I've even heard of ghost tours of the Smithsonian Museum,
which is a bit depressing actually when you see anybody
devoted to science promoting pseudo science to get the people
to wander through as of excitement to the newseum and
then make some money out of side.
Speaker 1 (16:50):
Quick be Queen is NASA who promoted peroge moons as
being supermoons. Anything to get people interested in science, no
matter what it takes.
Speaker 4 (16:58):
Yes, I find that rather sad. I think that anything
including studo science to get people interous from the science.
But it's happening all over the place. You'll find so
many buildings are sort of be promoted to get some
people wandering through. But this guy is obviously it has
quite a few runs on the board. He's got experience
in the haunting and he's sort of made a career
out of it, and that always worries me a bit.
Speaker 1 (17:15):
That's timendum from Australian Skeptics, and that's the show for now.

So don't miss out on this titan of a camera
that's real to capture your world like never before. That's
the Insta three sixty Go Ultra and now it's back
(09:40):
to our show. Well it may sound futuristic, but cydists
believe that space s based solar panels could eventually allow
humans to harvest energy from the sun almost continuously at
any moment of the day. The big problem with solar
panels and win turbines, of course, is that they don't
(10:02):
provide reliable electricity. That's because the sun doesn't shine all
the time and the wind doesn't blow continuously. Also, with
wind turbines, their carbon footprints greatly exceed the amount of
carbon they save, and both of the ongoing problem of
what to do with them when they wear out in
twenty years time. And that's why scientists engineers are looking
at alternatives, and one of them involved two space based
(10:25):
projects put solar panels in orbit. The first of the
two projects, named the innovative helio stats SWARM, is in
the early development but is the most likely to be
able to continuously capture solar energy. It's a space based
solar power concept involving a large array of mirror like
reflectors or helio stats in space that directs sunlight to
a central receiver, converting it into electricity, and then transmitting
(10:47):
it wirelessly down to worth, likely using either microwaves or
laser technology. The designing corporates innovations like retrodirective RF transmission arrays,
highly efficient PV cells, and modulustres. Overall, the model estimates
that the heliostat design will reduce total system costs by
about seven to fifteen percent, offset up to eighty percent
(11:08):
of wind and solar, and reduced battery usage but over
seventy percent. The second concept is named the mature planar array,
and it's much closer to being ready, but it will
only capture solar energy around sixty percent of the time. Still,
it's a big step from solar panels based on Earth.
The array uses an arrangement of solar antenna elements in
(11:29):
a flat rectangular grid, similar to those already used by
satellites and space stations, so we know it's going to
be reliable microwave or infrared emitters within the US to
transmit that energy data Earth. But a report in the
journal Dual warns that both current designs are still not
yet cost effective. Nevertheless, scientists hope the two systems can
(11:49):
be earned were to help with Earth's future net zero needs.
This is space time and time that told. Take another
(12:13):
brief look at some of the other stories making us
in science this week with the Science Report. A new
study claims that diets rich in a Mega three fatty
acids w you're found predominantly in fish may help board
off short sightedness in kids. Meanwhile, a high intake of
saturated fats found in foods such as butter, palme oil,
and red meat may increase the risk of short sightedness.
(12:33):
A report in the British Journal of Ophthalmology looked at
the eyesight of around a thousand children and compared the
development of our conditions against the results of a food
frequency questionnaire. They also asked how much time the kids
spent outdoors, how much time they spent reading and writing,
and how much time they spent on screens. The authors
found that the quarter of kids will consumed the least
amount of Amiga three fatty acids also had the largest
(12:55):
markers for the progression of short sightedness I. Meanwhile, the
quarter of children who had the highest intake of Amega
three fatty acids had the smallest incidents of the condition,
and they also found the inverse to be true for
kids who consume the highest intake of saturated fats. A
new study has shown that while fans can help keep
your cool in hot temperatures, in really dry hot temperatures
(13:18):
they'll actually make things worse. A reporting the Journal of
the American Medical Association subjected fifty eight people to various
three hour heat exposure tests, looking at how temperature and
humidity impacted the effectiveness of a fan or wetting the
skin or reducing body temperature and discomfort. The authors say
that in thirty eight degrees celsius heat with sixty percent humidity,
(13:38):
fan use margially improved body temperature and participants reported feeling
less warm. But in forty five degrees celsius dry heat,
they found that using a fan actually increased the participant's
body temperature as well as sweating, and made them feel
far more uncomfortable. A new study is shown that dogs
are more likely to react to on screen animal characters
(13:59):
than humans or other objects displayed on TV. The findings,
published in the journal Scientific Reports, examine the reactions of
four hundred and fifty puppies. The dogs reported as excitable
by their owners were more likely to follow on screen
animals as if they were real, while fearful or anxious
dogs were more likely to respond to stimulis such as
cars or a doorbell. The authors warn their findings may
(14:20):
not apply to all dogs, as the survey respondents were
all pet owners whose dogs regularly interacted with TV stimuli
and time now for our silliest story of the week,
and it seems there's a new contender for the title
of Britain's most haunted pub. The owner of the year
Oldie King's Head Hotel in Chester claims he's experienced bedcovers
wrapping tightly around him all by themselves, strange knocking noises,
(14:43):
and the sounds of ghostly children running down the hallway
to mend them from the strange skeptic says it's worth
pointing out the owner is developing a TV series based
on his claims.
Speaker 4 (14:53):
Through the hotel in Chester called The Oldie King's Hits,
which is the most haunted hotel in England, if not Britain.
They all, there's a lot of most haunted buildings in
the UK. Whatever saw it, and this one is one
that's had been around for a while. So the old
old pub that someone brought has did it up a bit,
and now suddenly there's all these sort of hauntings happening
from a more sort of ghost here than there is
(15:15):
any other haunted hotel. Roman warriors, Civil war soldiers, women
and children running up and down the corridors when it
was used as a brothel. Apparently, so it sounds exciting
this fellow who's bought it recently and renovated. There's now
put cameras in every room, which is a worry if
you want to stay there, Yes, and I think I
want to stay there someone watching me. Apparently people don't
stay there very long. They all go running away screaming
(15:36):
because it's a haunted place. But of course you have
to also keep in mind that this is a fellow
who hosts a podcast called My Haunted Project. He has
several properties and this Haunted Project is focused on quote
changing the paranormal and evolving it to a new level
based on real evidence I witness accounts in twenty four
to seven surveillance. He also has the whole range of
different displays, including the Great Dole, which is the haunted
(15:59):
or sort of cursed Dole, much like the Doll in
the US, much the same sort of thing, has her
own room. It's been a special glass case said to
be the UK's most haunted artifact. He's got a prime
video program called My Haunted Hotel series which features is
the Oldie King's Head pub he certainly has some money
in this that he wants this to be true. Whether
he really believes in it, there's certainly promotion. It's one
(16:21):
of the sad things that these days, so many groups,
so many buildings, so many organizations, are putting up their
premises for ghost to it.
Speaker 1 (16:28):
I was going to say he's got some competition because
just about every hotel in the UK is said to
be haunted.
Speaker 4 (16:33):
Yeah, every pub, every ancient castle, every you know what.
The same in the same in America as so many places.
I've even heard of ghost tours of the Smithsonian Museum,
which is a bit depressing actually when you see anybody
devoted to science promoting pseudo science to get the people
to wander through as of excitement to the newseum and
then make some money out of side.
Speaker 1 (16:50):
Quick be Queen is NASA who promoted peroge moons as
being supermoons. Anything to get people interested in science, no
matter what it takes.
Speaker 4 (16:58):
Yes, I find that rather sad. I think that anything
including studo science to get people interous from the science.
But it's happening all over the place. You'll find so
many buildings are sort of be promoted to get some
people wandering through. But this guy is obviously it has
quite a few runs on the board. He's got experience
in the haunting and he's sort of made a career
out of it, and that always worries me a bit.
Speaker 1 (17:15):
That's timendum from Australian Skeptics, and that's the show for now.
