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...

WASHINGTON, June 13, 2013 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope have found compelling evidence of a planet forming 7.5 billion miles away from its star, a finding that may challenge current theories about planet formation. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Of the almost 900 planets outside our solar system that have been confirmed to date, this is the first to be found at such a great distance from its star. The suspected...

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...

WASHINGTON, Jan. 30, 2013 /PRNewswire-USNewswire/ -- A star thought to have passed the age at which it can form planets may in fact be creating new worlds. The disk of material surrounding the surprising star called TW Hydrae may be massive enough to make even more planets than we have in our own solar system.

April Flowers for redOrbit.com - Your Universe Online A new study, using the capabilities of the Subaru Telescope, has captured a clear image of the protoplanetary disk of the star UX Tau A. An international team of researchers from the National Astronomical Observatory of Japan (NAOJ) and the Japanese universities of Kobe, Hyogo, and Saitama released a detailed study of the disk's characteristics, suggesting that its dust particles are large in size and non-spherical in shape. The...

WASHINGTON, Oct. 20, 2011 /PRNewswire-USNewswire/ -- Using data from the Herschel Space Observatory, astronomers have detected for the first time cold water vapor enveloping a dusty disk around a young star. The findings suggest that this disk, which is poised to develop into a solar system, contains great quantities of water, suggesting that water-covered planets like Earth may be common in the universe. Herschel is a European Space Agency mission with important NASA contributions....

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...

A stellar prodigy has been spotted about 450 light-years away in a system called UX Tau A by NASA's Spitzer Space Telescope. Astronomers suspect this system's central sun-like star, which is just one million years old, may already be surrounded by young planets. Scientists hope the finding will provide insight into when planets began to form in our own solar system. "This result is exciting because we see a gap, potentially carved out by planets, around a dusty sun-like star. In almost all...

How many stars does it take to "raise" a planet? In our own solar system, it took only one -- our Sun. However, new research from NASA's Spitzer Space Telescope shows that planets might sometimes form in systems with as many as four stars. Astronomers used Spitzer's infrared vision to study a dusty disk that swirls around a pair of stars in the quadruple-star system HD 98800. Such disks are thought to give rise to planets. Instead of a smooth, continuous disk, the telescope detected gaps...

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...
