Alan McStravick for redOrbit.com - Your Universe Online This week has certainly been heavy on extinction news. Seth Borenstein's enlightening AP article is one, detailing that the Earth may, in fact, be on the brink of the Sixth Great Extinction event. Citing the loss of species at a rate of 1,000 times faster than at any time prior to the rise of the human race, Borenstein's story states we are toying with disaster and whether or not humans make it out of this alive depends fully on...

redOrbit Staff & Wire Reports - Your Universe Online Plant and animal species are becoming extinct at rates more than 1,000 times more quickly than they did before the arrival of humans, indicating that the Earth could be edging closer to a sixth great extinction, according to a new study published May 30 in the journal Science. In the study, Duke University biologist Stuart Pimm and his colleagues examined both past and present rates of extinction using the IUCN Red List of...

redOrbit Staff & Wire Reports - Your Universe Online By reviewing hundreds of chemical analyses of lunar samples collected during the Apollo missions, scientists have discovered new clues about how water originated and was redistributed on the Moon, according to a recently published Nature Geoscience paper. Their findings could give experts a new tool to help unravel the processes that were involved in the Moon’s formation, as well as how the lunar crust cooled and the impact...

Hazy Titan Sunsets Help In Research Of Exoplanet Atmospheres
2014-05-28 06:49:53

Lawrence LeBlond for redOrbit.com - Your Universe Online By studying a hazy sunset on Titan via the Cassini spacecraft, scientists are learning new ways to better understand the atmospheres of exoplanets orbiting distant stars. Scientists developed a new technique based on the data provided by NASA’s Cassini mission that shows how hazy skies could impact the ability to study alien worlds. "It turns out there's a lot you can learn from looking at a sunset," Tyler Robinson, a NASA...

Carnegie Institution Breaking research news from a team of scientists led by Carnegie's Ho-kwang "Dave" Mao reveals that the composition of the Earth's lower mantle may be significantly different than previously thought. These results are to be published by Science. The lower mantle comprises 55 percent of the planet by volume and extends from 670 and 2900 kilometers in depth, as defined by the so-called transition zone (top) and the core-mantle boundary (below). Pressures in the lower...

New Techniques For Visualizing Fossils Are Transforming Our Understanding Of Evolutionary History
2014-05-23 03:35:03

University of Bristol Palaeontology has traditionally proceeded slowly, with individual scientists laboring for years or even decades over the interpretation of single fossils which they have gradually recovered from entombing rock, sand grain by sand grain, using all manner of dental drills and needles. The introduction of X-ray tomography has revolutionized the way that fossils are studied, allowing them to be virtually extracted from the rock in a fraction of the time necessary to...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online How do solar systems form? Specifically, why do some systems form smaller rocky worlds, while others are dominated by gas giants? A recent study led by Trey Mack, a graduate student in astronomy at Vanderbilt University, may have found the answer. Stars are dominated by hydrogen and helium, possessing only trace amounts of other elements – what astronomers generically call “metals”. Mack proposed looking at ratios of...

In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
