Although mass is the most important property of stars, it has proved very hard to measure for the lowest mass objects in the universe. Thanks to a powerful new camera, a very rare, low-mass companion ...

A research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with other researchers, has developed a new method to estimate how stellar-mass compact objects ...

When a star is young, it is often still surrounded by a primordial rotating disk of gas and dust, from which planets can form. Astronomers like to find such disks because they might be able to catch ...

The more our world fills up with junk, the more artists make supplies out of the detritus of our society. There are so many artists working with found object media now that there are ...

Neutron star and black hole masses in binary systems are calculable using Kepler's laws of motion, based on orbital parameters and object speeds. Merging neutron stars or black holes emit ...

The big picture: Quasars are the brightest objects known to exist in the universe, consisting of supermassive black holes that eat enormous amounts of matter. Astronomers recently revealed that ...
