The center of our Milky Way galaxy is a mysterious place. Not only is it thousands of light-years away, it's also cloaked in so much dust that most stars within are rendered invisible.

It is known today that merging galaxies play a large role in the evolution of galaxies and the formation of elliptical galaxies in particular.

Astronomers have discovered a rare beast of a galaxy cluster whose heart is bursting with new stars.

This Hubble Space Telescope image shows Messier 96, a spiral galaxy just over 35 million light-years away in the constellation of Leo (The Lion).

Bring on the night, say National Park visitors in new study University of Vermont Natural wonders like tumbling waterfalls, jutting rock faces and banks of wildflowers have long drawn visitors to America's national parks and inspired efforts to protect their beauty.

The Densest Galaxies Known

Two undergraduates at San Jose State University have discovered two galaxies that are the densest known.

Born-again Nebula

Beneath the vivid hues of this eye-shaped cloud, named Abell 78, a tale of stellar life and death is unfolding.

Starry Surprise in the Bulge

A team led by Andrea Kunder from the Leibniz Institute for Astrophysics Potsdam (AIP) measured the velocity of a sample of 100 old RR Lyrae stars* thought to reside in the galactic bulge, the central group of stars found in most galaxies.

Turbulent processes take place close to supermassive black holes, which lurk in the centres of nearly all galaxies.

A satellite experiment to study cosmic rays and the solar wind that was devised by school students is now successfully collecting data in space.

This NASA/ESA Hubble Space Telescope image shows a planetary nebula named NGC 6153, located about 4,000 light-years away in the southern constellation of Scorpius (The Scorpion).

Researchers from the National Astronomical Observatory of Japan, the University of Tokyo and other institutions have begun a wide-area survey of the distribution of dark matter in the universe using Hyper Suprime-Cam, a new wide-field camera installed on the Subaru Telescope in Hawai'i.

A NASA satellite controlled by Penn State University has detected a brief, super-bright, high-energy flare -- an X-ray nova -- erupting from a star system 8,000 light-years away from Earth named V404 Cygni.

Using the Subaru Telescope, researchers at the Special Astrophysical Observatory in Russia and Kyoto University in Japan have found evidence that enigmatic objects in nearby galaxies - called ultra-luminous X-ray sources (ULXs) - exhibit strong outflows that are created as matter falls onto their black holes at unexpectedly high rates.

A group of researchers from the Stony Brook University and the National Astronomical Observatory of Japan has discovered 854 "ultra dark galaxies" in the Coma Cluster by analyzing archival data from the Subaru Telescope.

Astronomers using NASA's Chandra X-ray Observatory have discovered the largest and brightest set of rings from X-ray light echoes ever observed.

Supermassive black holes lurk at the center of every large galaxy. These cosmic behemoths can be millions to billions of times more massive than the Sun.

Astronomers have used the Hubble Space Telescope's infrared vision to uncover the mysterious early formative years of quasars, the brightest objects in the universe.

Most galaxies are clumped together in groups or clusters. A neighboring galaxy is never far away.

ALMA's Long Baseline Campaign produced spectacular images of the distant, gravitationally lensed galaxy called HATLAS J090311.6+003906, otherwise known as SDP.81.
