exomoon candidate
2014-04-10 12:05:00

Whitney Clavin, NASA Jet Propulsion Laboratory Titan, Europa, Io and Phobos are just a few members of our solar system's pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun? NASA-funded researchers have spotted the first signs of an "exomoon," and though they say it's impossible to confirm its presence, the finding is a tantalizing first step toward locating others. The discovery was made by watching a chance encounter of objects in our galaxy, which...

asteroid impact
2014-04-10 08:39:56

Brett Smith for redOrbit.com - Your Universe Online Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa. Now, a new study published in the journal Geochemistry, Geophysics, Geosystems has outlined the details surrounding that massive impact, such as the creation of a crater about 300 miles across and...

Small Asteroid Regolith Formed By Thermal Fatigue
2014-04-04 06:21:44

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Small asteroids contain a layer of loose, unconsolidated rock and dust known as a regolith composed of centimeter-sized fragments and smaller particles. New research from researchers at the Observatoire de la Côte d'Azur, Hopkins Extreme Materials Institute at Johns Hopkins University, Institut Supérieur de l'Aéronautique et de l'Espace and Southwest Research Institute (SwRI), have now determined that this layer is formed by...

Ocean Inside Enceladus
2014-04-04 04:46:48

redOrbit Staff & Wire Reports - Your Universe Online The Cassini spacecraft and Deep Space Network have discovered evidence of a large underground ocean of liquid water on one of Saturn’s moons, suggesting that the satellite could be home to extraterrestrial microbes, according to research appearing in Friday’s edition of the journal Science. Marc Kaufman of National Geographic reports the ocean is located between the rocky core and a layer of thick ice on Enceladus , one of...

WASHINGTON, April 3, 2014 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft and Deep Space Network have uncovered evidence Saturn's moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the moon as a potential home to extraterrestrial microbes. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Researchers theorized the presence of an interior reservoir of water in 2005 when Cassini discovered water vapor and ice spewing from...

M-class Solar Flare
2014-04-03 06:12:35

Karen C. Fox, NASA's Goddard Space Flight Center On April 2, 2014, the sun emitted a mid-level solar flare, peaking at 10:05 a.m. EDT, and NASA's Solar Dynamics Observatory captured imagery of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To...

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...

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...
