What Has JWST Found So Far (opens the original)
Read excerpt
n this episode, we celebrate the third anniversary of the James Webb Space Telescope (JWST) . Since its launch on a pillar of fire in 2021, this "house-sized" observatory has moved beyond the limits of visible light to capture the universe in the infrared. From the chemical signatures of alien worlds to the "impossible" maturity of the first galaxies, Webb is not just taking pictures—it is rewriting the textbooks of cosmology. As we look to the next few years, the mission turns toward even deepe
Quest for Alien Moons (opens the original)
Read excerpt
In this episode, we venture into the frontier of a new astronomical chase: the hunt for the first "exomoon." We trace the story back to a strange eclipse 433 light-years away in the Centaurus constellation, where a "super-Saturn" planet named J1407b left observers puzzled until they realized a massive gap in its 37-ring system might be hiding an unseen, Earth-sized moon. We look at why finding these alien satellites is so critical, exploring how our own Moon acts as a vital planetary gyroscope t
How To Deal With An Explosion In Space Junk (opens the original)
Read excerpt
In this episode, we confront a tragedy of the commons playing out right above our heads. For six decades, humanity has launched rockets with a completely permissive attitude toward the mess left behind, and that carefree expansion has effectively walled us in. We begin with a harrowing, high-stakes red alert on the International Space Station, where the seven-person crew was forced to lock down modules and retreat into their docked lifeboats as a massive cloud of military shrapnel hurtled toward
Molecular Origins of Planetary Systems (opens the original)
Read excerpt
In this episode, we peer into the deep cosmic past to explore the molecular origins of planetary systems. We highlight the young star HOPS-315 in the Orion Molecular Cloud, where astronomers are watching crystalline silicate minerals condense from hot gas in real time, mirroring what our own Sun looked like 4.5 billion years ago. We dive into how space-based tools are cracking the secrets of these planetary nurseries, turning invisible infrared light into precise molecular barcodes that index wa
Black and Hot, Universe's Most Common Ice (opens the original)
Read excerpt
In this episode, we venture into the extreme target chambers of modern physics to explore superionic ice, or Ice XVIII. We begin in 2019 at the Laboratory for Laser Energetics, where scientists used gem-quality diamonds and one of the world's most powerful lasers to mimic the interior of alien worlds. By blasting a trapped water droplet with an intense shockwave, they subjected it to millions of atmospheres of pressure and temperatures hitting 5,000°C—uncovering the first direct evidence of a ma
