Astronomers Say Cosmic Barometer May Reveal Universe's Violent Past
2014-04-02 04:45:41

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online By studying the composition and other unique properties of sedimentary rock layers, geologists are able to trace the history of our Planet. They can identify periods of ice age, global climate shift, and even magnetic polarity shifts. In short, it is a clever way that researchers can use to reveal the major events in the history of our world. Now, astronomers from Imperial College London have taken this concept to a cosmic...

Radio Telescope Arrays Can Be Used To Locate Cosmic Heating From The Earliest Black Holes

[ Watch the Video: Black Holes Heated Gas Later Than Believed ] redOrbit Staff & Wire Reports - Your Universe Online In what is being described as a landmark discovery about the origins of the universe, Tel Aviv University researchers report in the journal Nature that black holes, formed from the first-ever stars, heated the gas throughout space much later than previously believed. In addition, study authors Professor Rennan Barkana of TAU's School of Physics and Astronomy, Dr....

No Planetary Influence On Solar Activity
2013-09-05 14:37:53

Lee Rannals for redOrbit.com - Your Universe Online New research in Astronomy & Astrophysics (A&A) is correcting errors in one statistical study published in the same journal last yea,r regarding the isotopic records of solar activity. Last year, astronomers wrote in the journal claiming that there is evidence of planetary influence on solar activity. However, the latest study refutes that claim, saying that they found no evidence of any planetary effect on the Sun. The Sun...

Twin Star Insights Into Sun's Future
2013-08-28 13:47:51

[ Watch the Video: The Life Cycle of a Sun-Like Star ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have identified what they are calling the Sun's oldest twin, HIP 102152, sitting 250 light-years away from us. A team of astronomers using the European Southern Observatory's (ESO) Very Large Telescope (VLT) found that HIP 102152 is older but otherwise nearly identical to our Sun, giving astronomers a chance to see how our local star will look as it ages. Our Sun is...

Louis Del Monte’s webisode merges historical references, new developments and scientific theories that argues life on other planets is probable. Minneapolis, Minnesota (PRWEB) June 21, 2013 Even though finding life on other planets in our galaxy eludes our technology today, physicists like Louis A. Del Monte find it a near mathematical certainty that life exists on other planets in the galaxy. In his newest two-part webisode, “Are There Other Earth-Like Planets?”, author, physicist...

Electrifying Exoplanets With Stellar Winds

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online When scientists began seeking out planets outside of our solar system, they anticipated seeing systems much like our own. Small, rocky worlds orbiting a couple of astronomical units from the host star, with the gas giant planets orbiting farther out. After all, much effort had been given to explaining how a solar system such as ours would form. Only, this is not what has been found. Many solar systems are constructed...

Billion Year-Old Water Found On Earth May Hold Key To Finding Life On Mars
2013-05-16 10:31:00

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online How did life begin? This question has been the focus of intense research for centuries, and while we have made significant strides, the answer still eludes us. Understanding how the first proteins, amino acids, and other organic compounds came together to form the first living cells is vital in our search for finding potential life on other worlds. And we have long thought that the key to life, here on Earth anyway, is...

Moon's Water Supply Came From Earth, Not From Comet Impacts
2013-05-09 13:34:08

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Prior to the Apollo Moon missions, scientists conjectured that the Moon would be extremely dry, that even below the surface of the Magnificent Desolation little or no water would be present. But the rocks brought back by the lunar explorers revealed that the Moon, while still dry compared to Earth, contained a surprising amount of water. Furthermore, the composition of the Moon led scientists to the current Big Impact...

WATCH VIDEO: [Swift's Christmas Burst From Blue Supergiant Star Explosion] Lee Rannals for redOrbit.com — Your Universe Online Researchers unwrapped a little more of the mystery surrounding a new type of powerful cosmic explosion, creating a new theory around the death of supergiant stars. These huge explosions create powerful blasts of high energy gamma rays, known as gamma-ray bursts. These larger blasts can last for several hours, compared to most gamma-ray bursts which...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Xenobiology -- Xenobiology (or exobiology, or astrobiology) is the term for a speculative field within biology which considers the possibility of, and possible nature of, extraterrestrial life. It also necessarily includes the concept of artificial life, since any life form might naturally evolve elsewhere, could conceivably come out of a laboratory using a future technology. It might be difficult to tell whether a truly strange life form had in fact arisen in space, or was designed much...
