Milky Way Caught Gobbling Up a Star Cluster

  Yale astronomers have caught the Milky Way having a snack. Using the Sloan Digital Sky Survey, researchers have discovered a stream, of stars believed to be the remnant of an ancient star cluster slowly being ingested by the Milky Way, Earth’s home galaxy. A map of stars in the outer region of the Milky Way [continue reading]

Black Widow Pulsar in Tango Mortale Vaporizes Partner

  Max Planck scientists discover record-breaking millisecond pulsar with new analysis method.   Pulsars are the compact remnants from supernova explosions of massive stars. Some of them spin around their own axis hundreds of times per second, emitting beams of radiation into space. Until now, they could only be found through their pulsed radio emissions.

The Revival of  a 'Dead' Exoplanet: Zombie Fomalhaut B

The Revival of a ‘Dead’ Exoplanet: Zombie Fomalhaut B

  A second look at data from NASA’s Hubble Space Telescope is reanimating the claim that the nearby star Fomalhaut hosts a massive exoplanet. The study suggests that the planet, named Fomalhaut b, is a rare and possibly unique object that is completely shrouded by dust. Fomalhaut, the brightest star in the constellation Piscis Austrinus. Image [continue reading]
