Astronomers using ESO's Very Large Telescope have discovered in a single pass about a dozen otherwise invisible galaxies halfway across the Universe. The discovery, based on a technique that exploits…

Astronomers have discovered one of the most bizarre planet-mass objects ever found. The object’s minimum mass is only about 7 times the mass of Jupiter. But instead of orbiting a normal star, this…

An international team of astronomers has announced the first discovery of a planet orbiting a star near the end of its life. The announcement, culminating seven years of research, will be published…

These NASA Hubble Space Telescope images reveal how the glowing gas ejected by dying Sun-like stars evolves dramatically over time. These gaseous clouds, called planetary nebulae, are created when…

Here are nine of the smallest, faintest, most compact galaxies ever observed in the distant universe. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a…

The Aurigid meteor shower peaked on September 1, originating from C/1911 N1 Kiess, or comet Kiess, a long-period comet that takes about 2000 years to orbit the Sun. It was discovered in 1935 by Carl…

British astronomers from the University of Cambridge and the California Institute of Technology (Caltech) have developed a new camera that gives much more detailed pictures of stars and nebula than…

Stars do not like to be alone. Indeed, most stars are members of a binary system, in which two stars circle around each other in an apparently never-ending cosmic ballet. But sometimes, things can go…

Scientists for the first time have observed elusive oscillations in the sun's corona, known as Alfvén waves, that transport energy outward from the surface of the sun. The discovery may give…

Astronomers at the University of Rochester have discovered five Earth-oceans’ worth of water that has recently fallen into the planet-forming region around an extremely young, developing star. Dan…
