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...

Brett Smith for redOrbit.com - Your Universe Online 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. “The detection of B-mode polarization by South Pole Telescope is a major milestone, a technical achievement that indicates exciting physics to come,” said study author John Carlstrom, a deputy director of...

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

Lee Rannals for redOrbit.com - Your Universe Online Physicists are now saying the universe may be closer to collapsing than previously believed. 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...

John P. Millis, PhD for redOrbit.com - Your Universe Online For several decades now the leading model for the origin and evolution of the known Universe is a concept known as the Big Bang. Nearly 15 billion years ago, quantum fluctuations of the infinite vacuum of space-time caused the emergence of a rapidly expanding Universe, ultimately filled with matter and radiation. But what initially caused the fluctuation? According to quantum mechanics, it is a natural result of the...

More Than Half A Million Galaxies Identified And Classified By The ALHAMBRA Project
2013-12-02 12:15:47

RUVID The ALHAMBRA project, led by researchers from the Instituto de Astrofísica de Andalucía and in which the University of Valencia has participated, has identified and classified more than half a million galaxies, after seven years of close observation of the universe from the Observatory of Calar Alto (CAHA, Almería) and thanks to a technique that breaks the stars energy in their colors through astronomical filters. In addition, this research has also allowed calculating the...

ESA Missions Will Seek To Understand The Evolution Of The Universe
2013-11-29 07:25:17

April Flowers for redOrbit.com - Your Universe Online 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. Bridging fundamental astrophysics and cosmology themes, both topics will closely study the processes that are crucial to the large-scale evolution of the Universe and its underlying physics. L2, the second large-class mission in ESA's Cosmic...

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

Alan McStravick for redOrbit.com - Your Universe Online 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. Prior to this new representation it was widely believed the stars in the core orbited in a sort of banana shape. However, scientists, publishing this week in the journal Monthly Notices of...

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...
