redOrbit Staff & Wire Reports - Your Universe Online Several processes typically limit how quickly black holes can grow, so how did those located at the ends of the universe come to have masses equal to several billion suns? Researchers from the Wiezmann Institute of Science and Yale University have proposed a potential solution in the latest edition of the journal Science. These enormous black holes, the study authors noted in a statement, consume large quantities of interstellar...

Colin Hunter, Perimeter Institute for Theoretical Physics Our universe may have emerged from a black hole in a higher-dimensional universe, propose a trio of Perimeter Institute researchers in the cover story of the latest Scientific American. The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three Perimeter Institute researchers have a new idea about what might have come before the big...

Hillary Sanctuary/Mediacom, Ecole Polytechnique Fédérale de Lausanne The Planck Telescope allowed physicists to draw the most detailed map of the first light emitted after the Big Bang. Some of its features do not entirely fit the standard cosmological theory, but scientists have discovered that these anomalies could be explained by how the data was processed. Last year, the Planck Telescope revealed the most detailed picture of the cosmic microwave background, the relic radiation...

redOrbit Staff & Wire Reports - Your Universe Online A massive new elliptical galaxy unexpectedly discovered using NASA’s Hubble Space Telescope is the most distant lensing galaxy ever discovered, officials from the US space agency confirmed in a statement Thursday. Lensing galaxies essentially act as a cosmic magnifying glass, and are large enough that their gravity can bend and distort light in such a way that they can make it easier to detect more distant objects in space....

redOrbit Staff & Wire Reports - Your Universe Online For the first time, astronomers have been able to precisely measure the mass of the Milky Way, and have discovered that our solar system's home is actually smaller than previously believed. As reported this month in the journal Monthly Notices of the Royal Astronomical Society, researchers from the University of Edinburgh, the University of British Colombia, Carnegie Mellon University and NRC Herzberg Institute of Astrophysics...

April Flowers for redOrbit.com - Your Universe Online The Hubble Space Telescope is a joint project between NASA and the European Space Agency (ESA) that launched in 1990. Since then, it has returned thousands of images from its orbital position above the atmosphere, helping scientists to shed light on some of the mysteries of the cosmos. Hubble images prove that there is more to a galaxy than what first meets the eye. The telescope is able to look beyond the bright glow of a galaxy's...

Verity Leatherdale, University of Sydney The discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees do but 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved. The finding, by an international team of astronomers, including Professor Geraint Lewis from the University of Sydney's School of Physics, was announced July 18 in Nature. "Early in 2013 we announced our startling...

Perimeter Institute for Theoretical Physics Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never mind the big bang; in the beginning was the vacuum. The vacuum simmered with energy (variously called dark energy, vacuum energy, the inflation field, or the Higgs field). Like water in a pot, this high energy began to evaporate –...

redOrbit Staff & Wire Reports - Your Universe Online The amount of light originating from known populations of galaxies and quasars is far less than the amount required to explain the amount of hydrogen that helps bridge empty spaces between galaxies, according to research appearing in a recent edition of The Astrophysical Journal Letters. In fact, as lead author Juna Kollmeier of the Carnegie Institution for Science and her colleagues explained in a statement Tuesday, the...

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...
