Louis Del Monte´s webisodes aim to address scientifically how the universe will end. Minneapolis, Minnesota (PRWEB) June 04, 2013 In his newest two-part webisode, “End of the Universe”, author, physicist and CEO, Louis A. Del Monte gives a scientific view of how the universe is likely to end in the extremely distant future. “The topic I chose for my latest webisode on the ℠End of the Universe´ was not meant to frighten viewers, but rather to illuminate what...

Galaxies Discovered Buried In Dust
2013-06-01 05:33:58

redOrbit Staff & Wire Reports - Your Universe Online Approximately 80 percent of all unidentifiable millimeter wave signals emitted in the universe actually originate from galaxies, according to new research published in Saturday´s edition of the Astrophysical Journal Letters. Based on observations collected using Atacama Large Millimeter/sub-millimeter Array (ALMA) telescopes, professor Kouji Ohta and postdoctoral researcher Bunyo Hatsukade of Kyoto University in Japan and...

Gravitational Lensing Used To Seek Out Most Distant, Active Star Forming Galaxies
2013-05-29 04:53:02

Lee Rannals for redOrbit.com - Your Universe Online Scientists working with the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered the most distant and active star forming galaxies in our universe. The astronomers wrote in the journal Nature and Astrophysical Journal that they discovered these distant and enigmatic galaxies after surveying large areas of the sky with the 10-meter South Pole Telescope. They used ALMA to help them obtain higher resolution images. The...

Cold Gas May Fuel Galaxy And Star Formation
2013-05-26 05:49:55

redOrbit Staff & Wire Reports - Your Universe Online As galaxies grow over the course of billions of years, they apparently use the cosmic equivalent of bendy straws to feed on cold gas and gain mass, according to new research published in the May 20 edition of the Astrophysical Journal. The study is based on computer simulations conducted by Kyle Stewart, who is currently with California Baptist University in Riverside but completed most of the research while with NASA´s Jet...

Measuring All Light Since Big Bang May Provide Answers To Evolution Of Universe
2013-05-24 14:07:39

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in The Astrophysical Journal that they have made the best measurement of all the light in the universe since the Big Bang yet. Measuring the number and energy of each particle of light or photon since the Big Bang could provide secrets about the nature and evolution of the Universe, such as how similar or different ancient galaxies were compared to the galaxies today. The researchers made the most accurate...

Mystery Of Nearby SS Cygni Star System Finally Resolved
2013-05-23 13:22:47

John P. Millis, PhD for redOrbit.com — Your Universe Online In 1990 the Hubble Space Telescope measured the distance to a nearby star system known as SS Cygni. Composed of a low-mass main sequence star and a compact object known as a white dwarf — a stellar remnant about the mass of our Sun, but compressed to the size of the Earth. The distance measured by Hubble puzzled scientists, as the measured brightness of the system was considerably higher than expected. If correct,...

PAPER Instrument In The Karoo Producing Ground-breaking Science And Spectacular Cosmic Images
2013-05-10 09:57:52

SKA Scientific studies done with the "PAPER" array, one of the world-class scientific instruments in South Africa's Karoo Radio Astronomy Reserve, is producing ground-breaking science and spectacular cosmic images, resulting in several important articles in top astronomy journals. The primary goal of PAPER (Precision Array to Probe the Epoch of Reionization) is to detect emission from the neutral gas that pervaded the universe before the first galaxies and black holes were formed. This...

Del Monte Gives His Perspective of M-Theory and Its Importance to Science Minneapolis, Minnesota (PRWEB) May 09, 2013 Author, physicist and CEO, Louis A. Del Monte helps make important science theories easy to understand in his video series on YouTube. While many compelling science concepts covered in best-selling books and cable channels are intriguing, topics can be difficult to grasp. This week Del Monte explains salient popular science ideas about M-Theory in layman´s terms in his...

Pear Shaped Atomic Nuclei
2013-05-09 11:28:49

Brett Smith for redOrbit.com - Your Universe Online According to a study in the journal Nature, a team of international scientists has found the first ever direct evidence of pear-shaped atomic nuclei. Bizarre pear-shaped nuclei could be the key to understanding one of the great mysteries of the universe: the reason for the Big Bang´s creation of a massive imbalance between matter and antimatter. "If equal amounts of matter and antimatter were created at the Big Bang, everything...

Clouds Of Hydrogen Gas Found In Our Galactic Backyard
2013-05-08 12:37:51

Watch the video “Intergalactic Clouds Lurk Between Nearby Galaxies" John P. Millis, PhD for redOrbit.com — Your Universe Online As we gaze into space beyond the confines of our own Milky Way, we see a Universe filled with galaxies. But what scientists have come to realize is that the emptiness that spans between these giant pools of stars is not empty at all, but rather is filled with massive amounts of gas. In fact, these gas reservoirs can sometimes outweigh the galaxies...

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...
