Habitable Zone Larger Than Believed
2014-01-08 14:32:50

[ Watch the Video: Life In The Habitable Zone ] Lee Rannals for redOrbit.com - Your Universe Online A new paper published in the journal Planetary and Space Science claims planets that were once thought uninhabitable may actually be able to contain life after all. University of Aberdeen scientists say that earth-sized planets are able to support life at least ten times farther away from stars than previously thought. This idea challenges the traditional 'habitable zone' theory...

Gemini Planet Imager Tracks Down Giant Planet Orbiting Beta Pictoris
2014-01-07 13:47:41

Brett Smith for redOrbit.com - Your Universe Online The internationally operated Gemini Observatory has announced the start-up of its new Gemini Planet Imager (GPI), a device designed to capture images of planets outside our Solar System and probe their atmospheres. The imager, which released its first image on Tuesday, was deployed on the observatory’s 8-meter Gemini South telescope in Chile. "Even these early first-light images are almost a factor of 10 better than the previous...

Binary Asteroid

[ Watch the Video: Binary Asteroid System Discovered ] Brett Smith for redOrbit.com - Your Universe Online An undergraduate astronomy class for non-astronomy majors at the University of Maryland has made a rare discovery that was completely overlooked by professional scientists: a pair of asteroids that orbit and regularly eclipse each other located in the main asteroid belt between Mars and Jupiter. There are currently fewer than 100 known eclipsing binary asteroids and the...

[ Watch The Video: Young Astronomers to Investigate the Outer Solar System ] National Science Foundation With support from the National Science Foundation (NSF), astronomers Marc Buie and John Keller are involving citizen scientists from throughout the western United States to participate in "RECON," which stands for the Research and Education Cooperative Occultation Network. The project has provided telescope equipment and training to 14 small western US communities north and...

Storms As Big As Jupiter's 'Great Red Spot' Found On Brown Dwarfs
2014-01-07 11:57:11

[ Watch the Video: Torrential Storm Clouds On Brown Dwarfs ] Lee Rannals for redOrbit.com - Your Universe Online Most brown dwarfs may contain storms as big as Jupiter’s “Great Red Spot,” according to findings presented at the American Astronomical Society in Washington. Brown dwarfs are a form of star, but lack the mass to fuse atoms continually to turn themselves into a full-fledged star. The celestial bodies are like a cross between a Jupiter-sized gas planet and a star....

Exoplanet Gassy Earth
2014-01-07 09:54:01

John P. Millis, PhD for redOrbit.com - Your Universe Online The holy grail of planet hunting is to find the first Earth-like world. While candidates have been found, there has yet to be confirmation about their particular characteristics. However, a new discovery, made possible by an international team of astronomers, has located the first confirmed Earth-mass planet occulting -- that is, passing in front of -- its host star. Even though the tiny world has the same mass as our planet,...

Rocky Exoplanets Too Hot To Support Life: Kepler Data
2014-01-07 05:07:34

Lee Rannals for redOrbit.com - Your Universe Online NASA’s Kepler spacecraft team reported details about five new rocky planets on Monday at the American Astronomical Society meeting in Washington. Kepler has helped scientists discover hundreds of exoplanets, and astronomers at the event reported on four years of follow-up observations, as well as describing the new rocky planets discovered. According to the latest findings, Kepler-99b and Kepler-406b are 40 percent larger in size...

Car-Sized New Year's Asteroid Enters Earth Over Atlantic Ocean

[ Watch the Video: First Asteroid Of 2014 ] Gerard LeBlond for redOrbit.com - Your Universe Online According to NASA, the first asteroid of the 2014 season was discovered by Catalina Sky Survey, a NASA-sponsored observatory near Tucson, Arizona. It has been designated as 2014 AA and was viewed moving across the sky early Wednesday morning, January 1, 2014. The size of 2014 AA was estimated to be between seven and 10 feet and had the potential of striking Earth. The exact path of the...

Sun Emitted Two Solar Flares Saying Goodbye To 2013 And Hello To 2014
2014-01-03 07:27:26

NASA The sun ushered out 2013 and welcomed 2014 with two mid-level flares on Dec. 31, 2013 and Jan. 1, 2014. 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. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours....

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...
