Latest PSR B1257+12 Stories
Astronomers, using CSIRO's Parkes telescope, have found evidence that a tiny star 37,000 light-years away from Earth is being bombarded by asteroids.
Three planets -- each orbiting its own giant, dying star -- have been discovered by an international research team led by a Penn State University astronomer.
An international team of astronomers has discovered an exotic planet that appears to be made of diamond orbiting a tiny star in our galaxy.
Astronomers have uncovered new evidence that planets might rise up out of a dead star's ashes. Spitzer surveyed the scene around a pulsar and found a surrounding disk made up of debris shot out during the star's death throes.
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.
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.
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...
