Billion Ton Asteroid Smashes Into Tiny Star In Puppis Constellation
2014-02-20 13:05:00

[ 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...

Chandra X-ray Observatory Sees Runaway Pulsar Firing A Record-breaking Jet
2014-02-19 09:27:55

NASA NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles. The pulsar, a type of neutron star, is known as IGR J11014-6103. IGR J11014-6103's peculiar behavior can likely be traced back to its birth in the collapse and subsequent explosion of a massive star. Originally discovered with the European Space Agency satellite...

Revealing New Information On Strength Of Black Hole Mergers
2013-11-08 07:13:10

Lee Rannals for redOrbit.com - Your Universe Online The Commonwealth Scientific and Industrial Research Organization (CSIRO) in eastern Australia has helped reveal new information about the strength of black hole mergers. Giant black holes throughout the universe sometimes pair up and merge, sending out gravitational waves that ripple across space and time. Albert Einstein predicted that these waves exist, but scientists have yet to directly detect one. Astronomers were able to...

Former Missile Tracking Telescope Tracks Evolution Of Crab Pulsar
2013-10-31 16:31:02

Lee Rannals for redOrbit.com – Your Universe Online A former missile tracking telescope has helped astronomers determine how the magnetic field structure and rotation of a young and rapidly rotating Crab pulsar evolves. Scientists wrote in the journal Science about a 22-year experiment that involved observing a steady change in the flashes of the Crab pulsar. This highly-compact star emits beams of radio waves that produce flashes each time it rotates, which occurs about 30 times a...

Jekyll And Hyde Pulsar Has A Split Personality
2013-09-26 04:31:06

Lee Rannals for redOrbit.com - Your Universe Online [ Watch the Video: Millisecond Pulsar with Magnetic Field Structure ] Scientists writing in the journal Nature say they have discovered a millisecond pulsar with a dual identity. The team used NASA's Swift and Chandra X-ray Observatory to find a pulsar that readily shifts back and forth between two mutually exclusive styles of pulsed emission, including one in X-rays and another in radio. Scientists say this discovery represents an...

New Pulsars Discovered In Archival Data
2013-08-29 08:25:39

AlphaGalileo Foundation Einstein@Home discovers 24 new pulsars in archival data. The combined computing power of 200,000 private PCs helps astronomers take an inventory of the Milky Way. The Einstein@Home project connects home and office PCs of volunteers from around the world to a global supercomputer. Using this computer cloud, an international team lead by scientists from the Max Planck Institutes for Gravitational Physics and for Radio Astronomy analyzed archival data from the CSIRO...

Future Space Missions Could Rely On Pulsars For Navigation
2013-08-21 13:36:21

Lee Rannals for redOrbit.com - Your Universe Online Scientists at Commonwealth Scientific and Industrial Research Organization (CSIRO) are developing a new GPS method for spacecraft using pulsars. Pulsars are small spinning stars that emit regular pulses of radio waves and sometimes X-rays. CSIRO astronomers measure when these pulsar pulses arrive in our Solar System. This data can be used to give clues about the behavior of a pulsar itself or whether it is orbiting another star. Dr...

Astronomers Use The Very Long Baseline Array To Set New Record
2013-06-13 14:46:36

ASTRON An international team of scientists led by astronomer Adam Deller (ASTRON) have used the Very Long Baseline Array (VLBA) to set a new distance accuracy record, pegging a pulsar called PSR J2222-0137 at 871.4 light-years from Earth. They did this by observing the object over a two-year period to detect its parallax, the slight shift in apparent position against background objects when viewed from opposite ends of Earth's orbit around the Sun. With an uncertainty less than four...

Crab Nebula -- The Crab Nebula (Messier 1, NGC 1952) is the object the which started Charles Messier logging non-cometary objects on his Messier Catalog. It is the expanding cloud of gas thrown off in the explosion that gave rise to the 1054 supernova recorded by Chinese astronomers, now more than 6 light years across (the nebula is currently expanding at 1000 km/sec and the total mass of ejected material is about 0.1 solar masses). The supernova which produced it was bright enough to...
