Synopsis

Hints of Alien Life, a Galactic Mystery, and Juno's Safe Mode IncidentIn this episode of SpaceTime, we explore groundbreaking revelations suggesting the potential for alien life beyond Earth. Using NASA's Webb Space Telescope, astronomers have detected chemical signatures of dimethyl sulfide and dimethyl disulfide in the atmosphere of the exoplanet K2 18 b, a sub-Neptune world located 124 light years away in the habitable zone of its host star. While these findings are incredibly promising, researchers urge caution as they work to confirm these biosignatures through further observations.A Surprising Spiral Galaxy from the Early UniverseNext, we dive into the discovery of a surprisingly large spiral galaxy dating back 11.4 billion years, which challenges current models of galaxy formation. This massive galaxy, dubbed the "Big Wheel," is three times larger than expected for its time, prompting astronomers to rethink how galaxies can grow and evolve in the early universe. The implications of this finding could r
