Most Stars Form in Discs
The first geometric evidence of mass dependent redshift evolution of galaxies and the preference for stars to form in discs.
Just how far away is the Pleiades?
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.
What’s in a Heartbeat?
Instead of happily orbiting in circles with constant velocity, the two stars spend most of their time far apart, and a few harrowing hours racing past each other. Or, to put it another way: hours and hours of boredom punctuated by moments of sheer terror. This is a heartbeat star.
Cosmic rays on the sky – where do they come from?
Cosmic rays hit the Earth and produce showers of particles that can be detected on the ground. Understanding where these cosmic rays come from can help scientists pin down their sources and construct models for the magnetic field in our neighborhood.
Mature Galaxies in an Immature Universe
The authors use a deep survey to locate rare galaxies which were among the earliest to form.
