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

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

[ 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

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...

Exoplanet May Have Formed Through Core Accretion
2013-03-15 05:33:23

April Flowers for redOrbit.com - Your Universe Online An international team of astronomers has made the most detailed examination to date of the atmosphere around a Jupiter-like exoplanet using the Keck Observatory, one of the two largest optical telescopes in the world. The young exoplanet, orbiting the star HR 8799, has water and carbon monoxide in its atmosphere. It does not, however, have methane, suggesting that a particular planet-forming mechanism, known as core accretion, brought...

Smallest Planet Ever Found By Kepler Scientists
2013-02-20 15:40:43

Lee Rannals for redOrbit.com - Your Universe Online Another new planetary system has been discovered by Kepler scientists, and this one happens to be home to the smallest planet ever discovered, circling around a star that is strikingly similar to our Sun. The Kepler-37 system sits about 210 light-years from Earth in the constellation Lyra. Only slightly larger than our moon, smaller than Mercury, and about a third the size of Earth, one of its planets is the smallest ever identified by...

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...

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...

Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...

Epsilon Eridani -- Epsilon Eridani is a main-sequence star in the constellation of Eridanus (the river). It is often used in science fiction because it is extremely sunlike, and in the fictional Star Trek universe it is the home sun of the planet Vulcan which is home to Mr. Spock. It is the third closest star visible without a telescope. It has 85% of the Sun's mass, almost that much of its diameter, and 28% of its luminosity. It is 10.5 light years from Earth. Its spectrum is...

La Silla Observatory -- La Silla is a 2400-m mountain, bordering the southern extremity of the Atacama desert in Chile. It is located about 160 Km north of La Serena. Its geographical coordinates are: Latitude 29 15' south & Longitude 70 44' west. Originally known as Cinchado, the mountain was renamed La Silla (the saddle) after its shape. It rises quite isolated and remote from any artificial light and dust sources (astronomy's worst enemies). La Silla was the first ESO...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
