For years we have observed the compelling fluvial features on the Martian surface. How did they get there? Was there a large ocean? Check out the very first measurements of how much water once flowed on Mars 4.5 billion years ago.
Today we’ll be discussing a paper that leverages some of these early ALMA observations as well as observations at the VLT in Chile to investigate the dynamical state of molecular gas in the ‘overlap’ region of the Antennae Galaxies.
Remember that tidal disruption event we talked about earlier this year, where a star got just a little too close to a quiescent black hole? Well, here’s our chance to witness something similar, happening in the center of our very own galaxy!
Where can you find ‘ghost’, ‘dark’, ‘stripped’, and ‘bullet’ clusters? The Pandora Cluster, which has become an excellent laboratory for studying the nature of other shady characters in our universe like dark matter.
