The SPHERE planet-hunting instrument on the European Southern Observatory's Very Large Telescope captured this image of a white dwarf feeding on its companion star, a type of Red Giant called a Mira variable. Most stars exist ...
Astronomers use stellar eclipses to study the atmosphere of accretion disks around compact stars. SRON-researchers observed this method on a low-mass X-ray binary. They find a thicker atmosphere than predicted and distinguish ...
Most stars with the mass of the sun or larger have one or more companion stars, but when and how these multiple stars form is one of the controversial central problems of astronomy. Gravity contracts the natal gas and dust ...
A stellar mass black hole is a compact object with a mass greater than three solar masses. It is so dense and has such a powerful force of attraction that not even light can escape from it. They cannot be observed directly, ...
Globular clusters could be up to 4 billion years younger than previously thought, new research led by the University of Warwick has found.
Imagine only knowing 15 people in the world, and as you discover more people, your knowledge expands. Scientists studying our galaxy face something similar as they make discoveries that build our understanding of the universe.
Planets orbiting "short-period" binary stars, or stars locked in close orbital embrace, can be ejected off into space as a consequence of their host stars' evolution, according to new research from the University of Washington.
