Scientists have charted the environment surrounding a stellar-mass black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station.

The Space Telescope Science Institute (STScI) in Baltimore, Maryland, in conjunction with the University of Hawaii Institute for Astronomy (IfA), is releasing the second edition of data from Pan-STARRS -- the Panoramic Survey Telescope & Rapid Response System -- the world's largest digital sky survey.

Investigating the history of our cosmos with a large sample of distant 'active' galaxies observed by ESA's XMM-Newton, a team of astronomers found there might be more to the early expansion of the Universe than predicted by the standard model of cosmology.

A new telescope will take a sequence of hi-res snapshots with the world's largest digital camera, covering the entire visible night sky every few days -- and repeating the process for an entire decade.

A new method to measure the temperature of atoms during the explosive death of a star will help scientists understand the shock wave that occurs as a result of this supernova explosion.

Including the powerful ALMA into an array of telescopes for the first time, astronomers have found that the emission from the supermassive black hole Sagittarius A* (Sgr A*) at the center of our galaxy comes from a smaller region than previously thought.

Hubble's Cosmic Holiday Wreath

This festive NASA Hubble Space Telescope image resembles a holiday wreath made of sparkling lights.

A billion light-years from Earth lies one of the universe's most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies known as Abell 2597.

A Tiny Old Star Has A Huge Impact

A tiny star found in our galactic neighborhood is presenting astronomers with a compelling glimpse into the history of our galaxy and the early universe.

Earth's Dust Cloud Satellites Confirmed

A team of Hungarian astronomers and physicists may have confirmed two elusive clouds of dust, in semi-stable points just 400,000 kilometres from Earth.

Astronomers from The Australian National University (ANU) and CSIRO have witnessed, in the finest detail ever, the slow death of a neighbouring dwarf galaxy, which is gradually losing its power to form stars.

Super-Slow Pulsar Challenges Theory

An international team of astronomers have discovered the slowest-spinning radio pulsar yet known.

Almost all galaxy clusters experience mergers. While a merger takes place, a specific pattern of "spiral" often can be observed in X-ray images.

The Moon may be the key to unlocking how the first stars and galaxies shaped the early Universe.

About a year ago, astronomers excitedly reported the first detection of electromagnetic waves, or light, from a gravitational wave source. Now, a year later, researchers are announcing the existence of a cosmic relative to that historic event.

The International Space Station was orbiting about 256 miles above South Australia when a camera on board the orbital complex captured this celestial view of Earth's atmospheric glow and the Milky Way.

More than 30,000 celestial images that were all but lost to science are about to find their way back into researchers' hands thanks to the efforts of thousands of citizen scientists.

Recent observations create a puzzle for astrophysicists: since the big bang, less galaxy clusters have formed over time than was actually expected.

A team of astronomers using the latest set of data from ESA's Gaia mission to look for high-velocity stars being kicked out of the Milky Way were surprised to find stars instead sprinting inwards - perhaps from another galaxy.

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have discovered a fast-moving jet of material propelled outward from a type of neutron star previously thought incapable of launching such a jet.
