Blue Exoplanet Shares Earth Color Only
2013-07-11 09:39:25

Brett Smith for redOrbit.com - Your Universe Online Using imagery from the Hubble Space Telescope, astronomers have determined that a planet orbiting a star close to our solar system has a deep azure blue color when seen from space, much like Earth. The international team that made the discovery noted similarities between these two planets likely end at their color, as the exoplanet HD 189733b is being described as a gas giant with thousand degree temperatures and violent winds in its...

Searching For Water Around Other Stars
2013-07-05 04:46:26

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Astronomers search for planets using several different techniques; the most popular of which is to measure how a star "wobbles." As the surrounding planets orbit the star, their gravitational fields will cause the star to shift back and forth in response. From these wobbles researchers can derive the mass and distance of any planets present in the system. Naturally, astronomers have been hoping for decades now to find an...

Researchers Look At Hot Jupiters And Planetary Migration
2013-06-07 07:20:56

April Flowers for redOrbit.com — Your Universe Online Stars have an alluring pull on the planets that surround them, especially a class of planets known as hot Jupiters. These planets are gas giants that form farther from their stars before migrating inward and heating up. Hot Jupiters, despite their close-in orbits, are not regularly consumed by their stars, as a new study conducted with data from NASA´s Kepler Space Telescope reveals. These planets remain in fairly stable...

KELT Discovers Metal-poor Cousin Of Famous Planet
2013-06-05 13:43:05

University of Louisville A scientific team led by University of Louisville doctoral student Karen Collins has discovered a hot Saturn-like planet in another solar system 700 light-years away. Collins announced the discovery of exoplanet KELT-6b Tuesday, June 4, during the American Astronomical Society's national meeting in Indianapolis. Astronomers caught sight of the planet when it passed in front of, or "transited," its host star–and they've since discovered that the planet...

Low-Budget Ground Telescope Pinpoints Gas Giant Exoplanet
2013-06-04 13:45:19

Lee Rannals for redOrbit.com — Your Universe Online Scientists announced during the American Astronomical Society´s (AAS) national meeting in Indianapolis this week that they have discovered a hot Saturn-like planet in another solar system 700 light-years away. The team used an inexpensive ground-based telescope to discover KELT-6b, which resides in the constellation Coma Berenices near Leo. This exoplanet has an orbit that transits its star every 7.8 days. Because of the...

Weather Forecasting For Hot Jupiters
2013-05-25 06:34:23

[ Watch the Video: Big Weather on Hot Jupiters ] redOrbit Staff & Wire Reports - Your Universe Online The class of new worlds dubbed as “hot Jupiters” definitely live up to their name, according to new research that has recorded temperatures as high as 2400 degrees Kelvin (or more than 3800 degrees Fahrenheit) on one of these massive, close-orbiting exoplanets. According to NASA, those temperature readings were observed on a gas giant named HAT-P-2b by Nikole Lewis, a...

Hot Jupiters More Nuanced Than Expected
2013-05-07 10:16:25

April Flowers for redOrbit.com - Your Universe Online In addition to the eight beloved planets circling our Sun, our galaxy is literally teeming with an enormous variety of planets. More than 800 of the so-called exoplanets have been identified circling stars beyond our solar system. And several different “species” of exoplanets have been discovered as well, including so-called ℠roasters´ or ℠hot Jupiters,´ which are gas giants like our own Jupiter that...

Two Giant Planets, Companion Star Discovered In Known Planetary System
2013-01-25 09:56:36

Lee Rannals for redOrbit.com — Your Universe Online Astronomers discovered that the HAT-P-7 planetary system includes at least two giant planets and one companion star. The discovery of a previously unknown companion, HAT-P-7B, to the central star, HAT-P-7, as well as confirmation of another giant planet, HAT-P-7c, orbiting outside of the retrograde planet HAT-P-7b offers up new insights into how such planets may form. Astronomers used the Subaru Telescope to discover the first...

Exoplanet Gets Partially Evaporated By Host Star
2012-06-28 14:21:08

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have observed one planet in another solar system, similar to Jupiter, giving off a powerful burst of evaporation after passing by its parent star. Using the Hubble Space Telescope, astronomers saw exoplanet HD 189733b bathe in an intense X-ray radiation after its parent star gave off a violet flare. The team observed the planet with Hubble during early 2010 and late 2011, during which HD 189733b was silhouetting its...
