April Flowers for redOrbit.com - Your Universe Online NASA's Space Shuttle Columbia carried the Chandra X-ray Observatory into space 15 years ago, deploying it on July 23, 1999. Chandra, along with the other "Great Observatories" like Hubble and Spitzer, has helped to revolutionize the way we view the Universe using an unprecedented X-ray vision. "Chandra changed the way we do astronomy. It showed that precision observation of the X-rays from cosmic sources is critical to understanding...

Aricebo Observatory Picks Up Mysterious Radio Burst From Beyond The Milky Way
2014-07-11 13:19:30

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Over the last few years the Parkes radio telescope in Australia has detected a handful of short radio bursts emanating from deep space. This was an amazing discovery, except for the fact that no other radio facilities had seen such pulses, leading some to suggest that the instrument was detecting terrestrial signals. But now, the Arecibo radio telescope has made a similar detection that has the astronomical community talking....

interstellar medium solves pulsar mystery

[ Watch the Video: Radio Wave Emission From A Pulsar ] John P. Millis, Ph.D. for redOrbit.com - Your Universe Online When a massive star, typically around 10 times the mass of our Sun, reaches the end of its main-sequence life, a series of events begins that eventually leads to a brilliant supernova. The shockwave from the event ejects most of the material into the surrounding interstellar medium, leaving a brilliant blanket of glowing gas that hangs in the sky for thousands of years....

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...

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...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
