In 2015, astrophysicists discovered a system consisting of two compact stars orbiting each other: a pulsar (i.e., a highly magnetized rapidly rotating, light-emitting neutron star) and a so-called companion star. The companion ...
University of Arizona astronomers have learned more about a surprisingly mature galaxy that existed when the universe was just less than 300 million years old—just 2% of its current age.
A total lunar eclipse will flush the moon red Thursday night into Friday morning across the Western Hemisphere.
Interstellar material has been discovered in our solar system, but researchers continue to hunt for where it came from and how it got here. A new study led by Western astrophysicists Cole Gregg and Paul Wiegert recommends ...
A new discovery about how tiny protein clusters form in cells could pave the way for treatments for Emery-Dreifuss muscular dystrophy (EDMD), a rare genetic disorder that causes muscle weakness and heart problems.
A fresh look at past data reveals that exoplanets with masses similar to Jupiter formed much sooner than previously thought, according to new research. The Ohio State University study's results provide new information about ...
Nova explosions occur in binary star systems in which a white dwarf—the dense remnant of a dead star—continually siphons stellar material from a nearby companion star. As the outer atmosphere of the companion gathers ...
Dust and rocks residing on the surface of the moon take a beating in space. Without a protective magnetosphere and atmosphere like Earth's, the lunar surface faces continual particle bombardment from solar wind, cosmic rays, ...
Binary neutron star mergers occur millions of light-years away from Earth. Interpreting the gravitational waves they produce presents a major challenge for traditional data-analysis methods. These signals correspond to minutes ...
The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star. Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have ...
