What makes galaxies stop forming stars? Is gas removed entirely, or simply heated to prevent stars from forming? Today’s paper uses observations of carbon monoxide in post-starburst galaxies to try to answer this question.
The Pleiades is one of the most well-known open clusters visible with the naked eye from Earth. But just how far away is the cluster? New results help determine a more accurate distance and suggest a troubling error in a previous study.
The diffuse gas contained within galaxy clusters can dramatically affect the galaxies moving within it. This includes bending the jets coming out of active galactic nuclei in galaxy clusters. The authors in today’s Astrobite report on extremely bent jets recently discovered in galaxy NGC 1272.
A mysterious Fast Radio Burst (FRB) from beyond the galaxy has been detected at Arecibo. This is the first FRB discovered outside of Parkes Observatory, giving greater credence to the astronomical nature of these signals.
Astronomers are hearing a new type of radio transient, but no one knows where they come from and how they are created. This paper suggests one of the six documented Fast Radio Bursts detected so far originated close to home, within our own galaxy.
