Astrobites reports on ALMA observations used to explore the effects of massive stars on gas and dust in galaxies.
Where does the angular momentum come from that causes supermassive black holes to spin on their axes and launch powerful jets?
Our measurements of exoplanet atmospheres may be influenced by the activity of the planets’ host stars.
Are small satellite galaxies usually distributed evenly around their larger galactic hosts? Evidence suggests otherwise.
Astrobites explores the role of magnetic fields in X-ray emission from the centers of active galaxies.
