Scientists Offer New Insights Into Early Universe
2012-11-29 15:54:22

Lee Rannals for redOrbit.com — Your Universe Online Penn State University scientists using techniques from modern physics have developed a new understanding of the earliest eras in the history of the universe. The scientists now have an extended analyses that include quantum physics farther back in time than ever before, heading back to the very beginning. The new paradigm of loop quantum origins show that the large-scale structures we see in the universe evolved from...

What Sparked The Origin Of Life
2012-11-27 06:45:21

April Flowers for redOrbit.com - Your Universe Online Scientists have questioned how life began on a molecular level for a very long time. And now, an international team of researchers has presented evidence that sheds light on a possible mechanism by which life may have gotten a foothold in the chemical soup that existed early in the Earth's history. Several competing theories have been previously proposed for how life got its start even before the first genes or living cells emerged....

Galaxy Clusters Offer Insight On Dark Matter
2012-11-21 09:56:07

April Flowers for redOrbit.com - Your Universe Online Dark Energy is one of the major puzzles of modern astronomy, and one tool that astronomers use to understand this force is encoded in the distribution of clusters of galaxies. A new study by a team of astronomers, led by Dr. Jeeseon Song at the University of Michigan, has yielded exquisitely precise distances of a large sample of clusters. These precise distances may lead to breakthroughs in understanding the expansion history of our...

Star Production In The Universe Is Slowing Down
2012-11-06 13:15:18

Lee Rannals for redOrbit.com - Your Universe Online Astronomers, writing in the journal Monthly Notices of the Royal Astronomical Society, have revealed that the rate of new stars in the Universe is dropping, which is a trend that could continue. The team of astronomers from five different countries said the rate of formation of new stars is now only 1/30th of its peak. The accepted model for evolution of the Universe suggests that stars began to form about 13.4 billion years ago....

"In our current paper we present new computational results that explore how membranes may influence crucial biological processes", explains Richard Matthews, Lise-Meitner-Fellow at the University of Vienna and first author of the study. The focus of the investigation is the self-assembly of microscopic particles, the formation of structures or patterns without human intervention. More specifically, the effect of the interactions between membranes and proteins, which can influence the...

Hubble Helps Map Dark Matter In 3D
2012-10-17 04:20:05

April Flowers for redOrbit.com - Your Universe Online A giant filament of dark matter extends 60 million light-years from one of the most massive galaxy clusters known. Leftover from the very first moments after the Big Bang, the filament is part of the cosmic web that constitutes the structure of the Universe. Scientists using the NASA/ESA Hubble Space Telescope have studied this filament in 3D for the first time and conclude that if the filament is representative of the rest of 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. 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...

Physics
2014-01-12 00:00:00

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Lyra Constellation -- Lyra (the lyre) is a prominent, although fairly small, northern constellation. It was one of Ptolemy's 48 constellations, and also counts among the modern 88 constellations. Its brightest star is Vega (Alpha Lyrae), which together with Altair (Alpha Aquilae) and Deneb (Alpha Cygni) forms the large asterism known as the Summer Triangle. Beta Lyr is a half separated (i.e. one of the stars reached its Rochevolume) eclipsing binary of a cream-white colour. The...

Cygnus Constellation -- Cygnus (the swan) is a northern constellation. It was one of Ptolemy's 48 constellations, and is also one of the 88 modern constellations. Because of the pattern of its main stars, it is sometimes called the Northern Cross (in contrast to the Southern Cross). The bird extends over the summer Milky Way, appearing to fly south. Notable features Cygnus contains several bright stars. Deneb, α Cygni, is an extremely brilliant star, very prominent despite...

Centaurus Constellation -- Centaurus (the centaur) was one of the 48 constellations listed by Ptolemy, and counts also among the 88 modern constellations. A constellation of the southern hemisphere, mentioned by Eudoxus (4th century B.C.) and Aratus (3rd century B.C.), Ptolemy catalogued thirty-seven stars in it. It contains Proxima Centauri, the red dwarf that is the nearest known star (other than the Sun) to Earth, as well as Alpha Centauri, which is a double star to which Proxima...
