In the Triangulum Galaxy, over the course of a hundred thousand years, three supernova exploded from the same star cluster. The remains of these explosions have expanded into a trio of giant bubbles nested within each other.
The author revisits a seminal article that reviews our understanding of AGN feedback, and comes out extremely impressed with the status quo (and the parallels with fictional universes).
NGC 3115, also known as the Spindle galaxy, is the nearest example to us of a lenticular galaxy – a strange hybrid of the more common spiral and elliptical galaxy types. But how can we find out how such galaxies are made? The European Southern Observatory’s MUSE instrument sheds some light.
Today’s guest post from Nimisha Kumari looks at how different properties of galaxies can affect the Schmidt-Kennicutt Law.
Our galaxy is not just made up of stars and dark matter, but a huge weight of dust, extending out much further than we can see. Now we’re starting to pin down the properties of our surrounding mysterious gas cloud, and new evidence shows that it’s busy doing it’s own thing.
Just when you think you’ve understood star formation and how galaxies form, someone pulls the rug out from under you…
