As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years.

A Black Hole's Heart Is Still Beating

The first confirmed heartbeat of a supermassive black hole is still going strong more than ten years after first being observed.

A new research paper co-authored by a Virginia Tech assistant professor of physics provides a new explanation for two recent strange events that occurred in Antarctica - high-energy neutrinos appearing to come up out of the Earth on their own accord and head skyward.

Almost like snowflakes, the stars of the globular cluster NGC 6441 sparkle peacefully in the night sky, about 13,000 light-years from the Milky Way's galactic center.

NASA's Solar Terrestrial Relations Observatory, or STEREO-A spacecraft, captured these images of comet ATLAS as it swooped by the Sun from May 25 - June 1.

Scientists have detected gamma rays from the Crab Nebula, the most famous of supernova remnants, using a next-generation telescope that opens the door for astrophysicists to study some of the most energetic and unusual objects in the universe.

Determined to find a needle in a cosmic haystack, a pair of astronomers time traveled through archives of old data from W. M. Keck Observatory on Maunakea in Hawaii and old X-ray data from NASA's Chandra X-ray Observatory to unlock a mystery surrounding a bright, lensed, heavily obscured quasar.

New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early universe took place sooner than previously thought.

About 3.5 million years ago, the supermassive black hole at the center of our Milky Way galaxy unleashed an enormous burst of energy.

A team of researchers, led by astrophysicist Sumner Starrfield of Arizona State University (ASU), has combined theory with both observations and laboratory studies and determined that a class of stellar explosions, called classical novae, are responsible for most of the lithium in our galaxy and solar system.

Astronomers using European Southern Observatory (ESO) telescopes have discovered giant spots on the surface of extremely hot stars hidden in stellar clusters.

The NASA/ESA Hubble Space Telescope was used to conduct a three-year study of the crowded, massive and young star cluster Westerlund 2.

Gravitational-wave researchers at the University of Birmingham have developed a new model that promises to yield fresh insights into the structure and composition of neutron stars.

In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late.

Researchers at UC Santa Cruz have developed a powerful new computer program called Morpheus that can analyze astronomical image data pixel by pixel to identify and classify all of the galaxies and stars in large data sets from astronomy surveys.

In the depths of the night sky lies a barred spiral galaxy called NGC 3583, imaged here by the NASA/ESA Hubble Space Telescope.

This sparkling spiral galaxy looks almost stretched across the sky in this new image from the NASA/ESA Hubble Space Telescope.

Black holes aren't stationary in space; in fact, they can be quite active in their movements.

Hubble Space Telescope's iconic images and scientific breakthroughs have redefined our view of the universe.

Galaxies grow large by eating their smaller neighbours, new research reveals.
