Exoplanet's Atmosphere Unveiled Through New Observing Technique
2012-06-27 13:04:31

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com Astronomers have uncovered a clever new way of studying the atmosphere of an exoplanet in more detail. An international team of astronomers used the European Space Observatory's Very Large Telescope to see the faint glow from the planet Tau Boötis b. For the first time, the team reported that it has been able to study the planet's atmosphere, and was able to measure its orbit and mass precisely. They wrote in...

Earth-like Planets May Be Scarce In Systems With Hot Jupiters

Solar systems that have “hot Jupiter-type” planets closely orbiting host stars likely do not have Earth-like planets neighboring them, according to a new study by researchers from University of Florida (UF), Fermilab, and Carnegie Institution. “Hot Jupiters” are giant planets that are roughly the size of Jupiter but orbit more closely to their parent stars, making them much hotter than Earth or Jupiter, according to Eric Ford, researcher at UF. These planets have...

Forming Planet Captured By Astronomer
2011-10-20 10:34:22

A University of Hawaii astronomer is credited with capturing the first direct image of a planet in the process of being formed around its star, reports the Associated Press (AP). Astronomer Adam Kraus, from UH at Manoa, made the discovery using the twin 10-meter Keck telescopes on Mauna Kea. He also used mirrors to cancel out starlight to view the phenomenon, a technique called aperture mask interferometry. It is usually impossible to capture such planetary births because the parent...

Distant Planet Blasted With X-rays From Nearby Star

  A nearby star is pummeling a companion planet with a barrage of X-rays 100,000 times more intense than the Earth receives from the sun. New data from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope suggest that high-energy radiation is evaporating about 5 million tons of matter from the planet every second. This result gives insight into the difficult survival path for some planets. The planet, known as CoRoT-2b, has a mass about...

The French-led CoRoT (Convection, Rotation and planetary Transits) satellite has found ten new planets outside our Solar System. The new find brings the total number of known exoplanets to 561.  CoRoT launched in 2006 and it spots planets by measuring the tiny dip in stellar light that occurs when planets pass between the stars and the Earth. The spacecraft has added 23 planetary systems to the roster so far. CoRoT went into orbit shortly after NASA's Kepler, which is a similar...

Scientists said on Wednesday the majority of the 500 planets detected around stars besides the Sun appear to spin the same way the star does. However, astronomers found that some of these extrasolar planets spin in the opposite direction of the stars they orbit. These backward-spinning planets usually are gassy giants called hot Jupiters. The scientists said these big planets huddle close to their stars, unlike Jupiter, which is about 483 million miles from the Sun. "That's really weird,...

Jupiter-like worlds around other stars push shock waves ahead of them, according to a team of UK astronomers. Just as the Earth's magnetic "bow-shock" protects us from the high-energy solar wind, these planetary shocks protect their atmospheres from their star's damaging emissions. Team member Dr Aline Vidotto of the University of St Andrews will present a new model based on observations made with the SuperWASP (Wide Angle Search for Planets) project on Monday 18 April at the National...

Recently published in an article of the Astronomy & Astrophysics journal, a group of researchers from the Institute of Space Sciences (IEEC-CSIC) at Universitat Autònoma de Barcelona has discovered, for the first time, a delta Scuti pulsating star that hosts a hot giant transiting planet. The study was carried out by the PhD student, Enrique Herrero, the researcher Dr. Juan Carlos Morales, the exoplanet expert, Dr. Ignasi Ribas, and the amateur astronomer, Mr....

Observations from NASA's Spitzer Space Telescope reveal a distant planet with a warm spot in the wrong place. The gas-giant planet, named upsilon Andromedae b, orbits tightly around its star, with one face perpetually boiling under the star's heat. It belongs to a class of planets termed hot Jupiters, so called for their scorching temperatures and large, gaseous constitutions. One might think the hottest part of these planets would be directly under the sun-facing side, but previous...

UA astronomers have developed a way to see faint planets previously hidden in their star's glare. The new mode enables scientists to search for planets closer to the star than has been previously possible.Using new optics technology developed at the University of Arizona's Steward Observatory, an international team of astronomers has obtained images of a planet on a much closer orbit around its parent star than any other extrasolar planet previously found.The discovery, published online in...
