Moon-Forming Impact Dated
2014-04-03 04:49:12

redOrbit Staff & Wire Reports - Your Universe Online Using a new method for estimating the moon’s age, an international team of planetary scientists has determined that the satellite formed nearly 100 million years after the formation of the solar system, according to research published Thursday in the journal Nature. The study authors came to that conclusion based on measurements from the Earth’s interior, as well as computer simulations of the protoplanetary disk from which...

Medical experts Dr. Sarah Miller and Dr. Joseph Horrigan weigh in and offer helpful tips on navigating flip-flop weather patterns with less pain. Marina Del Rey, CA (PRWEB) April 01, 2014 “A storm is coming…I feel it in my joints.” For many of the estimated 52.5 million arthritis sufferers in the United States (according to the CDC), these words are familiar. Yet, can arthritic joints really predict the weather? Once written off as an old wives’ tale, this kind of prediction is...

Mass Extinction During The Great Dying Caused By Microbial Methane
2014-04-01 11:49:56

Brett Smith for redOrbit.com - Your Universe Online Over 250 million years ago a mysterious event dubbed the Great Dying wiped out 90 percent of all species on Earth. Scientists have debated the culprit behind this mass extinction event for years, and a new study from MIT researchers has concluded that countless, tiny microbes released catastrophic amounts of methane into the atmosphere – choking off species that could not adapt. Previous research has fingered raging volcanoes...

Astronomers Given A Better Ruler In The Search For Extrasolar Planets
2014-03-31 08:04:47

NIST Researchers at the National Institute of Standards and Technology (NIST) have rejuvenated a technique for finding planets near distant stars. New measurements of light from special lamps could help astronomers find planets hidden in data from more than a decade's worth of extrasolar planet searches, as well as improve telescopes' current capabilities. Finding extrasolar planets is tricky. Seen through a telescope, planets in the "habitable zone"—a region close to a star, where...

Don’t Forget F-type Stars In The Search For Life
2014-03-27 13:19:34

University of Texas at Arlington Scientists searching for habitable planets beyond Earth shouldn’t overlook F-type stars in favor of their more abundant, smaller and cooler cousins, according to new research from University of Texas at Arlington physicists. Stars fall into seven lettered categories according to their surface temperature, but they also differ in other factors such as mass, luminosity and abundance in the universe. Scientists looking for habitable planets typically...

Lee Rannals for redOrbit.com - Your Universe Online Scientists have redefined the edge of the Solar System with the discovery of a new distant dwarf planet. The scientists reported in the journal Nature this week that they found 2012 VP113 sitting beyond the known edge of the Solar System. The new dwarf planet is one of thousands of distant objects believed to have formed in the inner Oort cloud. Not only does this new discovery bring into question the currently defined edge of the...

[ Watch the Video: Artist’s Impression of Ring System Around Chariklo ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the journal Nature say they have observed a minor planet which contains two rings of ice and pebbles for the first time. Chariklo sits about 1.2 billion miles out in the solar system between Saturn and Uranus, and the minor planet, or asteroid, has been known about for many years. However, this is the first time astronomers discovered...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...
