Someone dimmed the lights in space. Scientists observe a dimming quasar for the first time ever, and this could lead to a understanding of the mysterious black holes and their lifespans.

Traveling to planets in a galaxy far, far away – like in the movie Interstellar – may seem like science fiction, but what if the Milky Way was one massive conduit connecting to another far-off point hundreds of light years away?

The stage has been set for a explosion of apocalyptic proportions, as two distant supermassive black holes just one light-year apart are on a collision course that could result in the destruction of their home galaxy and release as much energy as 100 million supernovas.

New isolated dwarf galaxy discovered in the Local Group

Don’t look now, Milky Way, but it appears that there’s a new dwarf galaxy in the neighborhood.

An unusual photon emission in X-ray data originating from space could be evidence for the existence of a dark matter particle, researchers from the Swiss Federal Institute of Technology in Lausanne (EPFL) report in a new study.

Recently, the infrared Herschel Space Observatory, has taken a series of beautiful high-resolution infrared images of Andromeda. It is the first time we can see M31, at these wavelengths, at such a high resolution.

How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? An international team of researchers, led by astronomers at the University of California, Riverside, proposes some answers.

Researchers from the University of Nevada, Reno and the University of Victoria have found a new use for the Global Positioning System — the direct detection and measuring of dark matter.

black hole spotters guide
2014-11-17 05:28:01

Astronomers have developed what they are calling a “spotters guide” to black holes that could help scientists better detect the faint ripples of gravitational waves caused by black holes colliding millions of years ago.

An experiment carried into space on a NASA sounding rocket has detected a diffuse cosmic glow that appears to represent more infrared light than is produced by the known galaxies in the universe.

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies. Credit: NASA/Wikipedia What is Cosmology? I once commented to an acquaintance that I was fascinated by the field of Cosmology, and mused that if I had more time, I...

The Virgo Cluster consists of galaxies at a distance of around 59 Mly away in the constellation Virgo. Containing between 1300 to 2000 galaxies the Virgo Cluster is the heart of the Local Supercluster. Its mass is estimated at 1.2 × 1015 M☉ out to 8 degrees of the cluster's center or a radius of about 2.2 Mpc. Most of the brighter galaxies in the cluster were discovered by Charles Messier in the late 1770's and early 1780's, including the giant elliptical Messier 87. Messier...

The Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...

As of 2009, JKCS 041 is a group of galaxies with the distinction of being the farthest away group from Earth ever observed. Seen at redshift 1.9, it is estimated to be 10.2 billion light years away. The cluster is located within the constellation Cetus at a photometrically determined redshift of z=1.9 at right ascension 2h 26m 44s declination -04° 41"² 37"³ (J2000.0).

Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...
