TW Hydrae’s Snow Line Offers Insight Into Solar System Formation
2013-07-18 18:16:42

Brett Smith for redOrbit.com - Your Universe Online Astronomers at the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have announced the discovery of a distant solar system's "snow line" about 175 light years away, according to a report in Science Express. On Earth, a snow line can be seen at high altitudes, where a mountain's snowcap ends. The concept is similar in space, where a snow line forms at a certain distance from a star. Water, which has one of highest freezing...

Hubble Captures Planet Formation 7.5 Billion Miles From Host Star
2013-06-13 15:09:54

Lee Rannals for redOrbit.com — Your Universe Online Astronomers using NASA's Hubble Space Telescope say they have discovered evidence of a planet forming 7.5 billion miles away from its host star. The exoplanet is under construction about 176 light-years away from Earth in the constellation Hydra the Sea Serpent. The suspected planet is orbiting the diminutive red dwarf TW Hydrae. "It's so intriguing to see a system like this," said John Debes of the Space Telescope Science...

The Sun Was A 'Feisty' Character In Its Younger Days
2013-06-06 12:57:33

Lee Rannals for redOrbit.com — Your Universe Online Astronomers said during a press conference at a meeting of the American Astronomical Society that when our Sun was in its infancy, it was active and "feisty." The team said that when the Sun was young it was growing in fits and burping out bursts of X-rays. They came to this conclusion after studying another young star in our galaxy known as TW Hydrae, which sits about 190 light-years away in the southern constellation Hydra the...

Least Massive Exoplanet Outside The Solar System Observed By ESO Telescope
2013-06-03 05:43:49

Lee Rannals for redOrbit.com — Your Universe Online Astronomers using the European Southern Observatory's (ESO) Very Large Telescope (VLT) have imaged possibly the faintest exoplanet so far. The team reported in Astrophysical Journal Letters that they imaged a faint object moving near a bright star. The exoplanet has an estimated mass of four to five times that of Jupiter, which could potentially make it the least massive planet to be directly observed outside the Solar System....

TW Hydrae Protoplanetary Disk Weighed With Unprecedented Accuracy
2013-01-30 13:26:09

Lee Rannals for redOrbit.com - Your Universe Online Astronomers recently reported in the journal Nature that they have determined the mass of the planetary nursery surrounding the star TW Hydrae with unprecedented accuracy. TW Hydrae lies roughly 176 light-years away from Earth and is one of the most frequently observed protoplanetary disks in space. The young star is surrounded with a disk of dense gas and dust, in which larger objects begin to turn into planets. Our Solar System...

Image 1 - Astronomers Detect Water-Covered Planets
2011-10-20 13:44:37

The Herschel Space Observatory has helped astronomers detect water-covered planets like Earth around a young star. The astronomers used data from Herschel to detect cold water vapor enveloping a dusty disk around the young star.  This is the first time scientists have found evidence of vast quantities of water extending out into the cooler, far reaches of disks where comets take shape.  The more water available in disks for icy comets to form, the greater the chances that...

170 light-years away from earth exists a particularly puzzling orbiting object. This object, 2M1207B, seems to be physically impossible. Nothing about it matches any established astronomical theory. Eric Mamajek of the Harvard-Smithsonian Center for Astrophysics announced in a press conference, "This is a strange enough object that it needs a strange explanation." During this press conference, the 211th meeting of the American Astronomical Society, astronomers announced that 2M1207B might in...
