Based on observations from the South Pole Telescope, a team of international scientists has found subtle patterns in the cosmic microwave background called B-mode polarizations, according to a report in Physical Review Letters.

New Evidence Suggests Universal Collapse May Soon Be Upon Us
2013-12-12 15:09:39

Scientists have long predicted the universe could one day collapse, compressing everything contained within, much like a building that can’t contain its own weight. Sooner or later, scientists believe the universe will cause every little particle in it to become extremely heavy, causing all material to squeeze into a small, super-hot and super-heavy ball.

Recipe For Universe Heat Stir

The European Space Agency (ESA) announced today that the hot and energetic Universe and the search for elusive gravitational waves will be the focus of their next two large science missions.

Milky Way Seen More Clearly Than Ever Thanks To New 3D Map Of The Stars
2013-11-29 04:10:22

The Milky Way galaxy recently got a little easier to understand. A group of astronomers created a new 3D map of the stars that reside in the center of the Milky Way which shows, more clearly than ever, the bulge located at the core of our galaxy.

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...
