NASA's Chandra Observatory Searches For Trigger Of Nearby Supernova

NASA/Harvard-Smithsonian Center for Astrophysics New data from NASA’s Chandra X-ray Observatory offer a glimpse into the environment of a star before it exploded earlier this year, and insight into what triggered one of the closest supernovas...

zombie star after supernova
2014-08-07 07:21:49

Felicia Chou, NASA Headquarters and Donna Weaver / Ray Villard, Space Telescope Science Institute Using NASA’s Hubble Space Telescope, a team of astronomers has spotted a star system that could have left behind a “zombie star” after an unusually weak supernova explosion. A supernova typically obliterates the exploding white dwarf, or dying star. On this occasion, scientists believe this faint supernova may have left behind a surviving portion of the dwarf star -- a sort of zombie...

star cluster NGC 3293
2014-07-23 10:22:45

Richard Hook, European Southern Observatory (ESO) In this striking new image from ESO’s La Silla Observatory in Chile young stars huddle together against a backdrop of clouds of glowing gas and lanes of dust. The star cluster, known as NGC 3293, would have been just a cloud of gas and dust itself about ten million years ago, but as stars began to form it became the bright group of stars we see here. Clusters like this are celestial laboratories that allow astronomers to learn more about...

Iron 'Fingerprints' Point Astronomers To Supernova Remnants
2014-07-03 03:27:00

NASA An international team of astronomers using data from the Japan-led Suzaku X-ray observatory has developed a powerful technique for analyzing supernova remnants, the expanding clouds of debris left behind when stars explode. The method provides scientists with a way to quickly identify the type of explosion and offers insights into the environment surrounding the star before its destruction. "Supernovae imprint their remnants with X-ray evidence that reveals the nature of the...

redOrbit Staff & Wire Reports - Your Universe Online Many of the oldest and most massive galaxies reside together in enormous structures known as clusters, and now a team of astronomers has confirmed the existence of an unusually distant galaxy cluster – a group of 19 galaxies located at precisely the same distance of 9.9 billion light years. In research appearing in The Astrophysical Journal, Andrew Newman of the Carnegie Institution for Science and his colleagues explain how...

Supernovae Used To Gauge The Power Of Cosmic Lenses
2014-05-02 06:38:10

redOrbit Staff & Wire Reports - Your Universe Online Two teams of astronomers have used the Hubble Space Telescope to observe distant exploding stars, and their research could help determine the power of naturally-occurring “cosmic lenses” than can be used to magnify objects in the far-off universe, NASA officials announced on Thursday. The scientists, who are working independently, have studied three supernovae using the phenomenon of gravitational lensing, which causes the...

Gravitational Lensing Confirmed As Source Of Super-Luminous Supernova
2014-04-25 08:51:29

Lawrence LeBlond for redOrbit.com - Your Universe Online Four years ago a team of scientists observed a supernova – PS1-10afx – shining brighter than any other in its class. Reporting the observation last year in the Astrophysics Journal Letters, University of Tokyo researchers said they had discovered the first Type Ia Supernova (SNIa) that exploded more than nine billion years ago. Now, the same team of researchers, led by Robert Quimby, of the University of Tokyo’s Kavli...

Stellar Tape Measure
2014-04-11 05:13:14

NASA Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away -- 10 times farther than previously possible. Astronomers have developed yet another novel way to use the 24-year-old space telescope by employing a technique called spatial scanning, which dramatically improves Hubble's accuracy for making angular measurements. The technique, when applied to the age-old method for gauging distances called astronomical...

The Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...

  • 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.
