Disk Patterns Not Always Formed In Presence Of Planets
2013-07-13 07:16:03

[WATCH VIDEO: It Doesn't Take A Planet To Make A Ring] April Flowers for redOrbit.com - Your Universe Online Young stars known to host planets generally also have disks containing dust and icy grains, particles produced by collisions among asteroids and comets also orbiting the star. Often, these debris disks have sharply-defined rings or spiral patterns, which could signal the presence of orbiting planets. As a way to better understand the physical properties of known planets and...

Peculiar Dust Belts Found Around Six Stars
2013-07-10 05:19:51

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Besides the planets, comets, and asteroids that orbit our Sun, there are belts of rock and ice. Within these belts are dust particles, some which are fractions of a millimeter in size. As scientists have studied the heavens, they have located such disks orbiting other stars. "At least one fifth of stars are surrounded by dust belts like these," Alexander Krivov from the Friedrich-Schiller-University Jena explains. "They are...

Fomalhaut b’s Odd Orbit May Be Caused By Star’s Vast Debris Disk
2013-01-09 11:45:36

redOrbit Staff & Wire Reports — Your Universe Online According to newly released images from the Hubble Space Telescope, a vast debris belt circling around a nearby star is wider than scientists believe, and the unusual orbit of a planet traveling around that star could be to blame. In a statement released Tuesday, NASA officials stated that the images reveal that the debris disk traveling around the star Fomalhaut actually spans from 14 to 20 billion miles from the star...

WASHINGTON, Jan. 8, 2013 /PRNewswire-USNewswire/ -- Newly released NASA Hubble Space Telescope images of a vast debris disk encircling the nearby star Fomalhaut and a mysterious planet circling it may provide forensic evidence of a titanic planetary disruption in the system. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) Astronomers are surprised to find the debris belt is wider than previously known, spanning a section of space from 14 to nearly 20 billion miles from 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...

Zombie Planet Interview With Dr Thayne Currie
2012-11-02 14:22:24

Dr. John Millis and Jedidiah Becker for redOrbit.com — Your Universe Online In 2008, astronomers announced that the Hubble Space Telescope had captured images of an alien planet orbiting the nearby star Fomalhaut, located a mere 25 light years away in the constellation Piscis Austrinus. Dubbed Fomalhaut b and claimed as the first exoplanet to be confirmed through direct imaging in visible light, the planet appeared to orbit its star immersed in a massive ring of dust and debris....

Olivine Found In Beta Pictoris
2012-10-04 05:20:13

April Flowers for redOrbit.com - Your Universe Online European Space Agency's (ESA) Herschel Space Observatory has discovered pristine material that matches comets in our own Solar System in a dust belt around the young star Beta Pictoris. Beta Pictoris is 12 million years old, and resides a short 63 light-years from Earth. A gas giant planet and a dusty debris disc that has the potential to evolve into a torus of icy bodies like those of the Kuiper Belt found outside the orbit of...

Standard Model Does Little To Explain Why Earth Is So Dry
2012-07-18 10:59:10

Lawrence LeBlond for redOrbit.com - Your Universe Online Despite seventy percent of the Earth´s surface being covered by water, in reality the whole of the planet is only made up of 1 percent water, making it relatively dry compared to the gas giants, such as Jupiter and Neptune. And now, that dryness, which has long perplexed scientists, has been explained by a team of scientists working at the Space Telescope Science Institute (STSI) in Baltimore, Maryland. The standard model...

Comets Collide To Create Dust Belt
2012-04-12 04:45:20

The ESA´s Herschel Space Observatory has been studying the dust near the star Fomalhaut and has found the surrounding dust appears to have come from the dust of destroyed comets. A young star, Fomalhaut is estimated to be just a few million years old and twice as large as the sun. The dust belt near the star was discovered in the 1980s by the Infrared Astronomical Satellite (IRAS). Herschel's imaging technology and capabilities are able to capture a clearer picture of this dust belt,...
