Stellar Ballet: Apep's Cosmic Dance and Titan's Liquid Mystery

SpaceTime with Stuart Gary Gary - Series 28 Episode 150 In this episode of SpaceTime, we delve into intriguing discoveries and ongoing challenges in the realm of astrophysics and planetary science. Cosmic Dance of Dying Stars Astronomers have made fascinating observations of a unique star system named Apep, located over 8,000 light years away in the constellation Norma. This rare system consists of three massive stars locked in a 190-year orbit, creating stunning spirals of cosmic dust. Using the advanced capabilities of NASA's Webb Space Telescope and the Very Large Telescope in Chile, researchers captured extraordinary images revealing four distinct dust shells spiraling outward from the stars. Lead author Ryan White from Macquarie University discusses how these findings enhance our understanding of stellar interactions and the evolution of massive stars over time. Titan's Liquid Ocean: A New Perspective A recent study challenges the long-held belief that Saturn's largest moon, Titan, harbors a vast underground ocean. Instead, researchers suggest that Titan may have a more complex internal structure characterized by slushy tunnels and pockets of meltwater rather than a global liquid water ocean. This revelation, based on a reanalysis of data from NASA's Cassini mission, could have significant implications for the search for potential life on Titan, indicating that any existing life forms might inhabit a more confined environment with concentrated nutrients. NASA's MAVEN: Communication Challenges Mission managers at NASA are working diligently to restore contact with the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft, which went silent during a routine pass behind Mars on December 6. Engineers are analyzing data from before the loss of signal to identify the cause and determine if the spacecraft can be salvaged.
