SpaceTime with Stuart Gary Gary - Series 28 Episode 147
In this episode of SpaceTime, we delve into remarkable discoveries that significantly enhance our understanding of the cosmos.
Longest Gamma Ray Burst Ever Detected
Astronomers have made headlines with the discovery of the longest gamma ray burst ever recorded, GRB 250702B, which lasted over seven hours. This unprecedented event is reshaping our understanding of stellar explosions and their aftermath. Initial observations indicate that this extraordinary burst may have originated from a black hole consuming a star, prompting new theories about the mechanisms behind these powerful cosmic phenomena. We explore the implications of this finding and how it challenges existing models of gamma ray bursts.
Elemental Bounty in Supernova Remnant
For the first time, scientists have detected chlorine and potassium in the remnants of the supernova Cassiopeia A, utilizing the advanced capabilities of the CRISM spacecraft. This discovery sheds light on the elemental processes that occur during stellar explosions and their connection to the formation of elements crucial for life on Earth. We discuss the significance of these findings and their impact on our understanding of stellar nucleosynthesis.
International Space Station Fully Occupied
In a historic first, the International Space Station has reached full capacity, with all eight of its docking ports in use. We discuss the implications of this milestone, including the logistics of managing multiple spacecraft and the ongoing missions currently underway aboard the ISS.
