T Tauri star
2014-09-24 06:40:29

April Flowers for redOrbit.com - Your Universe Online Using the European Southern Observatory's (ESO) Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have observed what seems to be windy weather surrounding a T Tauri star—considered to be an infant analog of our own Sun. Such wind might explain why some T Tauri stars have disks that glow weirdly in infrared light while others have a more expected shine. The results of this study were published in a recent issue of the...

Lupus 4

Richard Hook, ESO Lupus 4, a spider-shaped blob of gas and dust, blots out background stars like a dark cloud on a moonless night in this intriguing new image. Although gloomy for now, dense pockets of material within clouds such as Lupus 4 are where new stars form and where they will later burst into radiant life. The Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile captured this new picture. [ Watch the Video: A Close-Up View Of The Dark...

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...

The Path To Planet Formation
2012-11-28 11:36:08

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...

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...
