A new survey of hot, X-ray-emitting gas in the Virgo galaxy cluster shows that the elements needed to make stars, planets and people were evenly distributed across millions of light-years early in cosmic history, more than 10 billion years ago.

Galaxies forming stars at extreme rates nine billion years ago were more efficient than average galaxies today, researchers find.

Astronomers using NASA's Hubble Space Telescope and the European Southern Observatory's (ESO) Very Large Telescope in Chile have discovered never-before-seen moving features within the dusty disk surrounding the young, nearby star AU Microscopii (AU Mic).

Galaxy clusters are often described by superlatives. After all, they are huge conglomerations of galaxies, hot gas, and dark matter and represent the largest structures in the Universe held together by gravity.

Hubble View of Veil Nebula Supernova Remnant

NASA's Hubble Space Telescope has unveiled in stunning detail a small section of the expanding remains of a massive star that exploded about 8,000 years ago.

Around 37,000 citizen scientists combed through 430,000 images to help an international team of researchers to discover 29 new gravitational lens candidates through Space Warps, an online classification system which guides citizen scientists to become lens hunters.

Messier 17: A Cosmic Rose With Many Names

This new image of the rose-coloured star forming region Messier 17 was captured by the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory in Chile.

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.
