In this episode of SpaceTime , we explore remarkable discoveries and hypotheses that could redefine our understanding of planetary atmospheres and our journey back to the Moon.
Phosphine Discovery in Brian Dwarf Wolf 1130C
For the first time, astronomers have detected phosphine in the atmosphere of the brown dwarf Wolf 1130C, raising intriguing questions about its presence and the chemistry of such celestial bodies. This discovery, reported in the journal Science, highlights the significance of phosphorus as a potential biosignature for life and challenges previous theories regarding the abundance of phosphine in other brown dwarfs and gas giants. The episode delves into the implications of this finding and what it means for our understanding of phosphorus chemistry in the universe.
A New Hypothesis for Planetary Water Formation
A groundbreaking hypothesis suggests that some planets may produce water during their formation through reactions between rocks and hydrogen under extreme pressure. This new perspective, discussed in the journal Nature, could explain the presence of liquid water on exoplanets located close to their host stars, challenging traditional views of water's origins. The episode examines the laboratory experiments that led to this hypothesis and its potential impact on our understanding of planetary habitability.
Preparing for Humanity's Return to the Moon
As NASA gears up for the Artemis 2 mission, which aims to send humans around the Moon, we discuss the significance of returning to the lunar south pole. This area is believed to contain more water than any other region on the Moon, making it a crucial target for future exploration. The episode highlights the advancements in technology and international collaboration that will pave the way for a sustained human presence on the Moon, furthering our exploration of the solar system.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
