Deep sea riches
2014-07-31 02:00:16

European Geosciences Union As fishing and the harvesting of metals, gas and oil have expanded deeper and deeper into the ocean, scientists are drawing attention to the services provided by the deep sea, the world’s largest environment. “This is the time to discuss deep-sea stewardship before exploitation is too much farther underway,” says lead-author Andrew Thurber. In a review published this week in Biogeosciences, a journal of the European Geosciences Union (EGU), Thurber and...

protoplanetary discs in a double star
2014-07-31 05:31:40

ESO Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas disks around the two young stars in the binary system HK Tauri. These new ALMA observations provide the clearest picture ever of protoplanetary disks in a double star. The new result also helps to explain why so many exoplanets — unlike the planets in the Solar System — came to have strange, eccentric or inclined orbits. The results will appear in the journal...

Enceladus South Pole
2014-07-29 03:45:31

Preston Dyches/Dwayne Brown/Steve Mullins, NASA Scientists using mission data from NASA's Cassini spacecraft have identified 101 distinct geysers erupting on Saturn's icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon's underground sea all the way to its surface. These findings, and clues to what powers the geyser eruptions, are presented in two articles published in the current online edition of the Astronomical Journal. Over a period...

April Flowers for redOrbit.com - Your Universe Online For decades, scientists have been debating over a fog of low-energy X-rays that has been observed over the entire sky. An international group of scientists has used a NASA-funded instrument to resolve this debate. The group refurbished detectors that were first flown on a NASA sounding rocket in the 1970s to confirm that much of this glow is generated by a region of million-degree interstellar plasma known as the local hot bubble (LHB)....

Leaf-mining Insects Completely Disappeared With The Dinosaurs
2014-07-28 03:16:19

By A'ndrea Eluse Messer, Penn State After the asteroid impact at the end of the Cretaceous period that triggered the dinosaurs' extinction and ushered in the Paleocene, leaf-mining insects in the western United States completely disappeared. Only a million years later, at Mexican Hat, in southeastern Montana, fossil leaves show diverse leaf-mining traces from new insects that were not present during the Cretaceous, according to paleontologists. "Our results indicate both that...

redOrbit Staff & Wire Reports - Your Universe Online Dinosaurs were victims of bad timing, and likely would have survived the asteroid impact that wiped them out had it occurred slightly earlier or later, researchers from Edinburgh University report in a new study. Dr. Steve Brusatte of the university’s School of GeoSciences and his colleagues explained that dinosaurs were at their most vulnerable when the asteroid hit, as a rising sea level and an increase in volcanic activity...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. 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...
