Repeating Space Signals FRBs 121102 Is No More A Mystery

April 1, 2016 |

Very recently, a team of scientists from CSIRO (the Commonwealth Scientific and Industrial Research Organization) detected ten bright bursts from the direction of the fast radio burst FRBs 121102. Read More

Astronomers Discovered Two New Exotic Pulsars PSR J0024−7204

March 7, 2016 |

By using the 64-m Parkes radio telescope, a team of scientists have discovered two new exotic millisecond pulsars in the globular cluster 47Tucanae (NGC 104), 16,700 light years away from Earth. Read More

PSR J0540-691: The First Extragalactic Pulsar Discovered by NASA

November 24, 2015 |

By analyzing data from NASA’s Fermi Gamma-ray Space Telescope, a group of researchers have found the first gamma-ray pulsar beyond our galaxy, called PSR J0540-691, the extraordinary object sets a new record of being the most luminous gamma-ray pulsar ever found to date. Read More

A Fast-Moving Pulsar Rips Hole Through Companion Star’s Disk

July 23, 2015 |

NASA’s sophisticated telescope, Chandra X-ray Observatory, has witnessed a fast-moving pulsar puncturing a huge hole in the massive companion star’s circumstellar disk of hot gas and dust. Read More

Astronomers Discover Unique Binary Pulsar System With The Widest Orbit Ever

May 4, 2015 |

Astronomers have confirmed the existence of an exotic pulsar with the widest orbit ever detected and is one of the very few binary neutron star systems known to date. Read More

Astronomers use a Pulsar to Measure Space-Time Warp for the First Time

January 9, 2015 |

A pair of stars orbiting each other has allowed astrophysicists to measure the space-time warp caused by the high gravity produced by the proximity of very heavy stars. Astronomer Ingrid Stairs and Joeri van Leeuwen, an astrophysicist at the Netherlands Institute for Radio Astronomy, and University of Amsterdam, are the first to see the disappearance of a neutron star due to gravitationally induced changes in space and time.

The Universe Never Stop to Surprising Us: Pulsar Lives in Triple System

May 12, 2014 |

Scientists have discovered a rapidly spinning neutron star with an unconventional living arrangement. This pulsar cohabitates with two white dwarfs, and the three are smashed together in a space smaller than Earth’s orbit around the Sun. The system is gravitationally extreme, with the three members all tugging on one another. Read More
