Gaia’s Final Scan, Milky Way’s Hidden Flares, and Unveiling New Planetary Mysteries: S28E10

SpaceTime Series 28 Episode 10

Gaia's Sky Scanning Completion and Mid Infrared Flare from Sagittarius A*

The European Space Agency's Gaia spacecraft has completed its sky scanning phase, marking a monumental achievement in astronomical missions. Over the past decade, Gaia has transformed our understanding of the Milky Way by mapping the positions and characteristics of billions of stars. This mission has provided unprecedented insights into the origins and evolution of our galaxy, revealing its structure and history like never before.

Mid Infrared Flare from the Milky Way's Supermassive Black Hole

Astronomers have detected a mid infrared flare from Sagittarius A*, the supermassive black hole at the center of the Milky Way. This discovery, made using NASA's Webb Space Telescope, fills a crucial gap in our understanding of black hole flares and supports existing models of magnetic reconnection in the accretion disk surrounding the black hole.

Discovery of a New Type of Exoplanet

NASA's Webb Space Telescope has unveiled a new type of exoplanet, unlike anything in our solar system. The planet, GJ1214B, exhibits a carbon dioxide-rich atmosphere similar to Venus, challenging previous assumptions about exoplanet atmospheres and providing new insights into planetary formation.
