But are black holes really like this? And what would happen if you fell into a black hole? What about a...

Galaxy Formation And Evolution Models Garner Award For Rutgers Astronomer
2013-01-25 07:55:22

Lee Rannals for redOrbit.com - Your Universe Online A Rutgers University astronomer has created computer models and simulations that help to explain how galaxies formed and evolved. Astronomer Rachel Somerville, who works as a professor of astrophysics in the Department of Physics and Astronomy, School of Arts and Sciences, created these models to show how gases like hydrogen and helium coalesce into stars and galaxies and how exploding stars and black holes impact their galactic...

NASA Joins ESA In Euclid Mission

Lee Rannals for redOrbit.com - Your Universe Online NASA and the European Space Agency (ESA) are partnering up on the Euclid mission to investigate dark matter and dark energy together. The Euclid space telescope will launch in 2020 with about a 4-feet-diameter telescope and two scientific instruments that will map the shape, brightness and 3D distribution of two billion galaxies. With the mission, "scientists hope to solve key problems in our understanding of the evolution and fate...

Taking Temperature Of Universe In Past Reveals Cooling Trend
2013-01-23 12:51:18

Lee Rannals for redOrbit.com — Your Universe Online Astronomers using the CSIRO radio telescope have discovered that the Universe's temperature has cooled down, which falls right in line with the Big Bang theory. An international team of astronomers from Sweden, France, Germany and Australia used the CSIRO Australia Telescope Compact Array near Narrabi to measure how warm the Universe was when it was half its current age. "This is the most precise measurement ever made of how...

In his new book, Engineering Physicist Daniel Friedmann shares his unique formula for converting ℠Bible Time´ to Gregorian years. Poised to provide compelling answers to the timeline aspects of the on-going Creation vs. Evolution debate, could the author´s new book be the answer both sides are fighting for? New York, New York (PRWEB) January 21, 2013 A new book by North American Physics Engineer, Daniel Friedmann, could be about to settle long-held differences between...

Fermi Telescope Turns to Dark Matter Search
2013-01-21 10:58:25

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online For much of the last century, scientists have been searching for a mysterious substance thought to make up about 85 percent of the total mass of the Universe. Without it, galactic rotation curves, galaxy interactions and the very structure of the Universe are inconsistent with our knowledge of physics. Yet, this so-called dark matter remains elusive. One reason researchers have had such a difficult time finding and...

Jedidiah Becker for redOrbit.com — Your Universe Online Over the years, the British cosmologist and theoretical physicist extraordinaire Stephen Hawking has become as well known for his ability to translate mind-boggling research about the universe into language that´s accessible to the layman as he is for his groundbreaking theoretical work in gravitational singularities and black hole radiation. This month, Cambridge´s wheelchair-bound conqueror of the cosmos turns 71....

New Book is a Trove of Incisive Insights on the Evolution of the Universe QUEBEC (PRWEB) January 15, 2013 The Big Bang theory is the prevailing paradigm in cosmology. In his new book, “Bright Hole Cosmos: and Multibang Dynamics”, author Andre Trepanier explores this cosmological model as he leads the way to a fascinating journey in the understanding of the evolution of the universe. Trepanier´s goal for writing his groundbreaking treatise is to challenge some of the main...

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...
