Black Holes Can Help Determine The Universe's Rate Of Expansion
2013-04-23 04:48:33

In 2011, the Nobel Prize for Physics was awarded to a trio of researchers. Adam Riess, Saul Perlmutter and Brian Schmidt were able to determine that the speed and scope of the expansion of the universe is not so uniform as once believed.

Most Distant Source Of High-Energy Gamma Rays Comes From Distant Blazar
2013-04-19 04:57:41

A team of physicists has made new observations of the blazar known as PKS 1424+240 that reveal it is the most distant known source of very high-energy gamma rays.

Stephen Hawking Touches On God And Dark Matter At Caltech Speech
2013-04-18 11:09:45

Although he probably never expected a career in physics would warrant it, Stephen Hawking received a ‘rock star’ reception to his speaking engagement at the California Institute of Technology (Caltech) in Pasadena, California on Tuesday.

Young Universe Was A Massive Factory For Star Formation
2013-04-17 13:36:09

Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old.

Big Bang In High Fidelity Sound
2013-04-10 10:53:15

"If the Universe started with a bang, and no one was alive yet to observe it, would it still make a sound?" It sounds like the start of a really cliché joke, but the answer, surprisingly, is yes.

Scientists Discover The Earliest Known Starburst Galaxies In The Universe
2013-04-05 15:32:28

An international team of researchers announced it has found some of the universe’s earliest starburst galaxies, essentially young energetic clusters of cosmic gas and dust that form stars at an alarming rate.

Hubble Space Telescope Breaks Record For Furthest Supernova
2013-04-04 12:49:29

The NASA/ESA Hubble Space Telescope has broken the record in the quest to find the furthest supernova of the type used to measure cosmic distances.

Evidence That Dark Matter Is Real
2013-04-04 05:36:28

For decades scientists have wondered whether a mysterious form of matter – known simply as Dark Matter since it does not interact directly with light – makes up the majority of the “stuff” 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...
