Scientists have opportunity to watch a planetary "death march" An international group of astrophysicists has determined that a massive planet outside our Solar System is being distorted and destroyed by its host star "“ a finding that helps explain the unexpectedly large size of the planet, WASP-12b. It's a discovery that not only explains what's happening to WASP-12b; it also means scientists have a one-of-a-kind opportunity to observe how a planet enters this final stage of its life....

NASA astronomers have successfully demonstrated that a David of a telescope can tackle Goliath-size questions in the quest to study Earth-like planets around other stars. Their work, reported today in the journal Nature, provides a new tool for ground-based observatories, promising to accelerate by years the search for prebiotic, or life-related, molecules on planets orbiting stars beyond our solar system. The scientists reported on a new technique used with a relatively small Earth-based...

GREENBELT, Md., Jan. 6 /PRNewswire-USNewswire/ -- The most earthlike planet yet found around another star may be the rocky remains of a Saturn-sized gas giant, according to research presented today at the American Astronomical Society meeting in Washington. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) "The first planets detected outside our solar system 15 years ago turned out to be enormous gas-giants in very tight orbits around their stars. We call them 'hot...

This week, Astronomy & Astrophysics is publishing a special issue devoted to the early results obtained with the CoRoT space mission. It includes 55 articles dealing with the primary goals of the CoRoT mission, that is, exoplanet hunting and asteroseismology, and also with other topics in stellar physics. Astronomy & Astrophysics is publishing a special issue this week dedicated to the early results of the CoRoT space mission [1]. The CoRoT (Convection, Rotation & planetary...

Peering far beyond our solar system, NASA researchers have detected the basic chemistry for life in a second hot gas planet, advancing astronomers toward the goal of being able to characterize planets where life could exist. The planet is not habitable but it has the same chemistry that, if found around a rocky planet in the future, could indicate the presence of life. "It's the second planet outside our solar system in which water, methane and carbon dioxide have been found, which are...

Mass and density of smallest exoplanet finally measured The longest set of HARPS measurements ever made has firmly established the nature of the smallest and fastest-orbiting exoplanet known, CoRoT-7b, revealing its mass as five times that of Earth's. Combined with CoRoT-7b's known radius, which is less than twice that of our terrestrial home, this tells us that the exoplanet's density is quite similar to the Earth's, suggesting a solid, rocky world. The extensive dataset also reveals the...

British scientists are trying to determine why a Jupiter-style planet orbiting close to its sun has not spiraled into the star and burned up. Wasp-18b is so close to the star Wasp-18 that it completes its orbit in less than an Earth-length day, astrophysicists at Keele University in Staffordshire say. In an article in Nature, they say standard astronomical theories hold the planet should have a lifespan of less than a million years, while Wasp-18b is believed to be a billion years old....

A team of scientists has found a new planet which orbits the wrong way around its host star. The planet, named WASP-17, and orbiting a star 1000 light years away, was found by the UK's WASP project in collaboration with Geneva Observatory. The discovery, which casts new light on how planetary systems form and evolve, is being announced today (12th August) in a paper submitted to Astrophysical Journal. Since planets form out of the same swirling gas cloud that creates a star, they are expected...

NASA's new exoplanet-hunting Kepler space telescope has detected the atmosphere of a known giant gas planet, demonstrating the telescope's extraordinary scientific capabilities. The discovery will be published Friday in the journal Science."As NASA's first exoplanets mission, Kepler has made a dramatic entrance on the planet-hunting scene," said Jon Morse, director of the Science Mission Directorate's Astrophysics Division at NASA Headquarters in Washington. "Detecting this planet's...

Astronomers have discovered a distant "sun" residing in the constellation Aquila, in what they are calling the smallest known star to host a planet, BBC News reported. Scientists used astrometry "” a method based on measuring small changes in a star's position "” to discover the Jupiter-like exoplanet orbiting the star VB 10. Experts say that VB 10 is one-twelfth the mass of the Sun, yet the star is more massive than its planet and has about the same girth. The upcoming edition...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
