A dwarf galaxy recently discovered orbiting the Milky Way appears to be radiating gamma rays, and leading researchers from Brown and Carnegie Mellon universities hypothesize that it could be filled with particles of the mysterious substance known as dark matter.
PITTSBURGH, March 10, 2015 /PRNewswire-USNewswire/ -- A newly discovered dwarf galaxy orbiting our own Milky Way has offered up a surprise -- it appears to be radiating gamma rays, according
One explosion is cool. But four? That's great. Astronomers observed a star explode as a supernova 4 different times in this effect known as the Einstein Cross.
Dust plays an extremely important role in the universe - both in the formation of planets and new stars. But dust was not there from the beginning and the earliest galaxies had no dust, only gas. Now an international team of astronomers, led by researchers from the Niels Bohr Institute, has 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...
Astronomers have long wondered exactly what fate befell the compact massive galaxies that could be found throughout the universe during its infancy, but new research from experts at the Swinburne University of Technology may have finally discovered the answer.
The South Pole Telescope is now ready for use in the search for black holes and will be joining its buddy, The Event Horizon Telescope.
The European Southern Observatory’s Very Large Telescope has one-upped the Hubble Space Telescope, producing the best-ever three-dimensional view of the deep universe while revealing previously invisible objects, ESO officials announced this morning.
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".
Insightful new expose reveals how faster than light travel, green energy development is achievable through physics METFORD, Australia (PRWEB) February 10, 2015
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 Ã— 1015 Mâ˜‰ 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 -04Â° 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...
