A new survey by the NASA/ESA Hubble Space Telescope and NASA’s Chandra X-ray Observatory studied 72 galactic cluster collisions from all different angles and times, revealing that the 85 percent of the universe’s total matter is way weirder than we could ever imagine.
Astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought, narrowing down what this crazy substance might be.
Dark energy is so difficult to understand, but this specific type of supernovae could help determine the rate at which the universe is expanding.
WASHINGTON, March 26, 2015 /PRNewswire-USNewswire/ -- Using observations from NASA's Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow
THE PRINCIPLE opened with high acclaim on March 13th at AMC Mission Valley 20, San Diego, Calif.
What is dark matter? And what is dark energy? These questions are what keep physicists awake late at night.
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...
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...
