Billion Ton Asteroid Smashes Into Tiny Star In Puppis Constellation

[ Watch the Video: Fight Between Tiny Star And Giant Asteroid ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have found evidence that a tiny star 37,000 light-years away from Earth is being bombarded by asteroids. Scientists say PSR J0738-4042, a star located in the constellation of Puppis, has been hit with an asteroid that had a mass of about a billion tons. The team used CSIRO's Parkes Observatory telescope and another telescope in South Africa to make the...

Astronomers Find New Planets And A Mystery Object Outside Our Solar System

Three planets -- each orbiting its own giant, dying star -- have been discovered by an international research team led by a Penn State University astronomer. Using the Hobby-Eberly Telescope, astronomers observed the planets' parent stars -- called HD 240237, BD +48 738, and HD 96127 -- tens of light years away from our solar system. One of the massive, dying stars has an additional mystery object orbiting it, according to team leader Alex Wolszczan, an Evan Pugh Professor of Astronomy and...

  An international team of astronomers has discovered an exotic planet that appears to be made of diamond orbiting a tiny star in our galaxy. The new planet, which is far denser than any other previously known, consists primarily of carbon.  However, its high density has led scientists to calculate the carbon must be crystalline, meaning a large part of the planet would effectively be diamond. "The evolutionary history and amazing density of the planet all suggest it is...

NASA's Spitzer Space Telescope has uncovered new evidence that planets might rise up out of a dead star's ashes. The infrared telescope surveyed the scene around a pulsar, the remnant of an exploded star, and found a surrounding disk made up of debris shot out during the star's death throes. The dusty rubble in this disk might ultimately stick together to form planets. This is the first time scientists have detected planet-building materials around a star that died in a fiery blast. "We're...

NASA -- The past four weeks have been heady ones in the planet-finding world: Three teams of astronomers announced the discovery of 12 previously unknown worlds, bringing the total count of planets outside our solar system to 145. Just a decade ago, scientists knew of only the nine planets - those in our local solar system. In 1995, improved detection techniques produced the first solid evidence of a planet circling another star. A proliferation of discoveries followed, and now dozens of...

Princeton -- Some extrasolar planets may be made substantially from carbon compounds, including diamond, according to a report presented this week at the conference on extrasolar planets in Aspen, Colorado. Earth, Mars and Venus are "silicate planets" consisting mostly of silicon-oxygen compounds. Astrophysicists are proposing that some stars in our galaxy may host "carbon planets" instead. "Carbon planets could form in much the same way as do certain meteorites in our solar system, the...

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...
