The Coma Cluster, a massive grouping of galaxies located 300 million light-years from Earth, is home to a group of 47 galaxies that are rich in dark matter and may be so-called ‘failed’ galaxies, researchers from Yale University report in a new study.

As crazy as it sounds, we’ve all kind of accepted the part of the Big Bang Theory that says the universe started as a single point around 13.8 billion years ago. The thing is – a lot of theoretical physicists aren’t enthralled with that idea, as a lot of widely-accepted general relativity equations start to break down as you approach the "singularity".

A cluster of young, pulsating stars discovered in the far side of the Milky Way may mark the location of a previously unseen dark-matter-dominated dwarf galaxy hidden behind clouds of dust.

The European Space Agency utilized polarized light from the earliest days of the universe to reveal that the first stars were formed 100 million years later than previously believed.

Reports published last year claiming to have detected evidence of gravitational waves emitted immediately following the Big Bang were inaccurate, new analysis of the data has revealed.

Even though dark matter is believed to make up 85 percent of the universe’s mass, no one has managed to detect the elusive material, but a new fundamental particle proposed by scientists at the University of Southampton could finally change that.

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?

black hole

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.

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.

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...
