Kinetic Sunyaev-Zel'dovich Effect Observed In Individual Object For The First Time
2014-01-17 11:14:32

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the California Institute of Technology (Caltech) and NASA’s Jet Propulsion Laboratory (JPL) report in a recent study that they have observed a change in an individual object’s cosmic microwave background radiation resulting from its interaction with massive moving objects for the first time ever. According to the recently-published paper in The Astrophysical Journal, this phenomenon, which is known as the...

Himiko Galaxy's 'Space Blob' Halo Dates Back To The Cosmic Dawn
2014-01-17 08:10:48

redOrbit Staff & Wire Reports - Your Universe Online Questions surrounding the glowing gaseous halo extending from a massive early galaxy that have puzzled astronomers since its discovery in 2009 have finally been answered by research appearing in a recent edition of The Astrophysical Journal. Himiko, a very large and extremely distant galaxy with a gaseous halo extending over 55,000 light years, was first discovered four years ago using the Subaru Telescope located at Hawaii’s...

One-Percent Accurate Measurement Of Universe Completed By BOSS
2014-01-09 09:02:10

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Baryon Oscillation Spectroscopic Survey (BOSS) announced on Wednesday that their project has measured the scale of the universe to an accuracy of one percent – precise measurements that will help astronomers in their search to determine the true nature of dark energy. “One-percent accuracy in the scale of the universe is the most precise such measurement ever made,” explained principal investigator David...

Hubble Detects Faintest-Ever Early Universe Galaxies
2014-01-08 04:44:58

redOrbit Staff & Wire Reports - Your Universe Online Using the Hubble Space Telescope, a team of researchers has discovered the smallest, faintest and most numerous galaxies ever discovered in the remote universe, according to research presented Tuesday at the annual meeting of the American Astronomical Society (AAS) in Washington DC. The University of California, Riverside-led team – whose research will also appear in the January 10 issue of The Astrophysical Journal – used...

Pixidis researcher Tom Whitney of Minneapolis has achieved the Holy Grail quest of modern physical science: the discovery of Einstein's famed unified field equation. Sought by thousands of scientists around the world, this equation reveals the ultimate blueprint running the universe. Minneapolis, MN (PRWEB) January 03, 2014 The unified field equation theorized to exist by Einstein has been discovered—uniting hundreds of years of multidisciplinary science in a single, historic fell...

According to Hubble’s law, the frequency of light from distant galaxies is shifted toward the red in a way proportional to their distance D, z = HD, where H is Hubble's constant. Dr. J. V. Kadeisvili of the Institute for Basic Research and of the R. M. Santilli Foundation announces that Dr. R. M. Santilli's invariant derivation of Hubble's law without expansion of the universe has been confirmed at five recent scientific meetings (for links to the meetings visit...

In a recent NPR interview, astronaut Chris Hadfield indicated that his spaceship became "blood red" when seeing Sunrise, thus confirming that Sunlight passing through our atmosphere experiences a redshift without relative motion. Dr. R. M. Santilli and Dr. j. V. Kadeisvili of of the Institute for Basic Research and the R M Santilli Foundation comment on Hadfield’s interview and how it supports the lack of expansion of the universe...

The historical, theoretical and experimental evidence on the lack of expansion of the universe was confirmed at five scientific meetings in Europe and in the Far East (http://www.santilli-foundation.org/Conf-2013-No-Univ-Exp.php). Palm Harbor, Florida (PRWEB) December 20, 2013 The historical, theoretical and experimental evidence on the lack of expansion of the universe was confirmed at five scientific meetings in Europe and in the Far East...

Urban Galactic Clusters Stopped Forming Stars Billions Of Years Ago
2013-12-19 12:36:09

Brett Smith for redOrbit.com - Your Universe Online A new study based on data from NASA’s Spitzer Space Telescope has revealed new details about so-called urban galaxies that exist in large clusters. The study found that these clusters stopped forming new stars about 9 billion years ago, much later than previously thought. These galactic cities were said to have eventually either used up or lost their fuel. Meanwhile, more rural galaxies are still actively forming stars. "We know...

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...
