Galactic cannibalism brings an exoplanet of extragalactic origin within astronomers' reach An exoplanet orbiting a star that entered our Milky Way from another galaxy has been detected by a European team of astronomers using the MPG/ESO 2.2-meter telescope at ESO's La Silla Observatory in Chile. The Jupiter-like planet is particularly unusual, as it is orbiting a star nearing the end of its life and could be about to be engulfed by it, giving tantalizing clues about the fate of our own...

Astronomers at the European Southern Observatory (ESO) have discovered five planets orbiting a star in what is being called by the AFP news agency "the biggest discovery of so-called exoplanets since the first was logged 15 years ago." The ESO astronomers discovered the planetary system around a sun-like star called HD 10180. Using the HARPS spectrograph, they also reportedly discovered evidence which suggests that there may be two additional planets present in orbit around the celestial...

Astronomers, including one at The University of Arizona, have successfully predicted the existence of an unknown planet, the first since Neptune was predicted in the 1840s. This planet, however, is outside our own solar system, circling a star a little more than 200 light years from Earth. The UA's Rory Barnes and his associates predicted the unknown planet from their theoretical study of the orbits of two planets known to orbit star HD 74156. Barnes announced the discovery today at the...

PASADENA, Calif. (AP) -- Astronomers have spotted a swirling debris cloud around a sun-like star where terrestrial planets similar to Earth may be forming in a process that could shed light on the birth of the solar system. The star, located 137 light-years away, appears to possess an asteroid belt, a zone where the leftovers of failed planets collide. Terrestrial planets are those with rocky surfaces, as opposed to a gas composition. Scientists estimate the star is about 30 million years...

JPL -- NASA's Spitzer Space Telescope has spotted what may be the dusty spray of asteroids banging together in a belt that orbits a star like our Sun. The discovery offers astronomers a rare glimpse at a distant star system that resembles our home, and may represent a significant step toward learning if and where other Earths form. "Asteroids are the leftover building blocks of rocky planets like Earth," said Dr. Charles Beichman of the California Institute of Technology, Pasadena, Calif....


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
