The distribution of matter in the Universe has much to say about its constituents and evolution. Can the distribution of voids also help us understand the Universe?
The moon provides an easy way to detect rare ultra-high-energy cosmic rays.
Observational biases may significantly underestimate the lifetime of protoplanetary disks.
KIC 2856960 appeared to be an interesting but straightforward triple star system in the Kepler catalog. But attempts to model this system prove that appearances can be deceiving.
The Sunyaev-Zeldovich effect is a unique way of searching for galaxy clusters that complements multi-wavelength imaging efforts.
For the first time, astronomers have announced a Thorne–Żytkow Object candidate- a bizarre system in which a neutron star is surrounded by an envelope of stellar material.
The first geometric evidence of mass dependent redshift evolution of galaxies and the preference for stars to form in discs.
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.
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 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.
