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

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

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...

Chance Alignment Mimics Cosmic Collision

[ Video 1 ] | [ Video 2 ] The NASA/ESA Hubble Space Telescope has produced a highly detailed image of a pair of overlapping galaxies called NGC 3314. While the two galaxies look as if they are in the midst of a collision, this is in fact a trick of perspective: the two just happen to appear in the same direction from our vantage point. NGC 3314A and B might look like they are in the midst of a galactic pile-up, but they are in fact separated by tens of millions of light years of void....

Image 1 - Astronomers Detect Water-Covered Planets

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...

The steady discovery of giant planets orbiting stars other than our sun has heightened speculation that there could be Earth-type worlds in nearby planetary systems capable of sustaining life. Now researchers running computer simulations for four nearby systems that contain giant planets about the size of Jupiter have found one that could have formed an Earth-like planet with the right conditions to support life. A second system is likely to have a belt of rocky bodies the size of Mars or...

Cambridge, MA -- Interstellar travelers might want to detour around the star system TW Hydrae to avoid a messy planetary construction site. Astronomer David Wilner of the Harvard-Smithsonian Center for Astrophysics (CfA) and his colleagues have discovered that the gaseous protoplanetary disk surrounding TW Hydrae holds vast swaths of pebbles extending outward for at least 1 billion miles. These rocky chunks should continue to grow in size as they collide and stick together until they...

A primitive star with extremely low iron content has been discovered by an international research team from Sweden, Japan, Germany, USA, Australia and Great Britain. This indicates the original composition of the gas from which the star formed had low iron content. The results are published in Nature online this week. In 2001, the giant star HE0107-5240 was discovered among a large number of stars examined as part of the Hamburg/ESO* survey. Detailed studies revealed that the star had by far...
