The Hubble Space Telescope has been in space for 28 years, producing some of the most beautiful and scientifically important images of the cosmos that humanity has ever taken. But let’s face it, Hubble is getting old, and it probably won’t be with us for too much longer.
NASA’s James Webb Space Telescope is in the final stages of testing, and WFIRST (Nancy Grace Roman...

In recent years, scientists have made great strides in the search for extraterrestrial life. They have discovered thousands of exoplanets. And some of them are located in the habitable zone of their star, which means that liquid water could exist on their surface and is essential for life as we know it....

A Mars-sized planet was found just 31 light-years away, orbiting its star every eight hours and having 55 percent the mass of the Earth, leading scientists to conclude it’s mostly made of an iron-nickel core. Plus, water on Earth, a huge comet, and a review of a Canon lens.

The night sky isn’t still. It’s full of brief, brilliant flashes called transient objects. In this episode we explain what they are, why they matter, and how you can help chase them!

Some comets orbit the Sun on a regular basis, but others come in from deep space, a region known as the Oort Cloud. What causes them to make this journey, and will we ever be able to explore the Oort Cloud?

The Total Emptiness of Cosmic Voids.
How do we actually define voids? Are there regions within them that are truly empty? What would it be like to be inside one? I discuss these questions and more in today’s Ask a Spaceman!

We’ll cover what the changes are and try to understand the implications. It's a bad decade to be a researcher. We're going to ...

From Jul 4, 2018.
For the first time ever, astronomers have captured a direct image of a newly forming planet orbiting around a newly forming star. It’s a stunning photograph, not only for the science and what was observed, but what it means the future of exoplanetary astronomy.

Join us as we look at two parallel stories - the development of the Vera Rubin Observatory and the SpaceX Starship rocket. Both projects are 20 years in the making, and both were supposed to start work in 2019. Both hit new milestones in June, and it's time to review their very different progress. Also included in this episode: Tales from the launch pad.

Black holes come in many sizes. Small, medium, large & extra large. The size of a black hole mostly depends on how massive the star was before it ran out of fuel, exploded as a supernova and collapsed under its own extreme gravity. The more massive the black hole, the stronger and larger its effect on the fabric of space and time.
Here’s the new bit! In a recent study, astronomers found...

The time has come. The mighty Vera Rubin Observatory has finally come on line and delivered its “first light” images. And by Pamela’s rules that means we get to talk about it! So let’s do that! After decades of waiting, we have images from Vera Rubin Observatory!
