Far from home: Wayward cluster is both tiny and distant

Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way's 'suburbs'. It is located where astronomers have never spotted such a small cluster of stars before.

Lots of light and little shadow on 67P Churyumov-Gerasimenko

On 14 February 2015, the Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS) on the Rosetta spacecraft observed the surface of comet 67P Churyumov-Gerasimenko with the Sun directly behind it, so the only shadow seen in the image is that of the photographer, the orbiter itself.

Astronomers find dust in the early universe

Astronomers have discovered a dust-filled galaxy from the very early universe. The discovery demonstrates that galaxies were very quickly enriched with dust particles containing elements such as carbon and oxygen, which could form planets.

New insight found in black hole collisions

New research by an astrophysicist provides revelations about the most energetic event in the universe - the merging of two spinning, orbiting black holes into a much larger black hole.

Looking deeply into the universe in 3-D

The MUSE instrument on ESO's Very Large Telescope has given astronomers the best ever three-dimensional view of the deep Universe. After staring at the Hubble Deep Field South region for only 27 hours, the new observations reveal the distances, motions and other properties of far more galaxies than ever before in this tiny piece of the sky. They also go beyond Hubble and reveal previously invisible objects.

Astronomers find impossibly large black hole

Astronomers have found a huge black hole which was powering the brightest object in the early universe. The black hole's mass is 12 billion solar masses, and the surrounding quasar pumped out 10^15 times the sun's energy.

Physicists offer a solution to the puzzle of the origin of matter in the universe

Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very small degree, has puzzled scientists for many years. New research offers a possible solution to the mystery of the origin of matter in the universe.

Giving shape to black holes' intense winds

By looking at the speed of ambient gas spewing out from a well-known quasar, astronomers are gaining insight into how black holes and their host galaxies might have evolved at the same time.
