Supernova Lights Up The Galactic Scene
2012-08-31 12:06:23

April Flowers for redOrbit.com - Your Universe Online A recent study, led by Edo Berger of Harvard University, made the most of a dying star's fury to probe a distant galaxy some 9.5 billion light years away. The most distant stellar explosion of its kind ever studied, that dying star lit up the galactic scene. “It´s like someone turned on a flashlight in a dark room and suddenly allowed us to see, for a short time, what this far-off galaxy looks like, what it is composed...

First Public Data Release From The Baryon Oscillation Spectroscopic Survey (BOSS)
2012-08-08 10:08:02

Led by Berkeley Lab scientists, the Sloan Digital Sky Survey´s BOSS is bigger than all other spectroscopic surveys combined for measuring the universe's large-scale structure The Third Sloan Digital Sky Survey (SDSS-III) has issued Data Release 9 (DR9), the first public release of data from the Baryon Oscillation Spectroscopic Survey (BOSS). In this release BOSS, the largest of SDSS-III's four surveys, provides spectra for 535,995 newly observed galaxies, 102,100 quasars, and 116,474...

Large Synoptic Survey Telescope Advanced By National Science Foundation
2012-07-19 11:47:37

With approval from the National Science Board, the National Science Foundation (NSF) Director will advance the Large Synoptic Survey Telescope (LSST) to the final design stage. This action permits the NSF Director to include funds for LSST construction in a future budget request. To be located in Chile, the LSST is a proposed 8-meter wide-field survey telescope that will survey the entire sky approximately twice per week, delivering a large and comprehensive data set that will transform...

City-Block Sized Asteroid Whizzing By Earth Tonight
2012-06-14 13:52:39

Lee Rannals for redOrbit.com A huge asteroid the size of a city block will be skimming by Earth on Thursday night at 8:00 eastern time. The giant space rock is about 1,650-feet wide and is big enough to qualify as a potentially hazardous asteroid.  However, experts stress there is no chance of a collision, and it will be passing Earth at a safe 3 million miles away. Astronomers in Australia discovered the asteroid 2012 LZ1 on Sunday night, and found that the object is going to...

Wise Finds Fewer Brown Dwarfs Than Expected
2012-06-10 04:49:55

Astronomers are getting to know the neighbors better. Our sun resides within a spiral arm of our Milky Way galaxy about two-thirds of the way out from the center. It lives in a fairly calm, suburb-like area with an average number of stellar residents. Recently, NASA's Wide-field Infrared Survey Explorer, or WISE, has been turning up a new crowd of stars close to home: the coldest of the brown dwarf family of "failed" stars. Now, just as scientists are "meeting and greeting" the new...

WISE Catches Cosmic Dust Bunny
2012-04-27 03:13:54

Images from NASA's Wide-field Infrared Survey Explorer (WISE) reveal an old star in the throes of a fiery outburst, spraying the cosmos with dust. The findings offer a rare, real-time look at the process by which stars like our sun seed the universe with building blocks for other stars, planets and even life. The star, catalogued as WISE J180956.27-330500.2, was discovered in images taken during the WISE survey in 2010, the most detailed infrared survey to date of the entire celestial sky....

Galaxy Could Be Teeming With 'Nomad Planets'
2012-02-24 09:17:30

Researchers at the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) suggest in a new study that the heavens could be teeming with “nomad planets,” wandering through space instead of orbiting around host stars. In fact, say the researchers, there could be 100,000 times more of these planets in the Milky Way alone than there are stars. And if observations confirm this estimate, it could affect the current theories of planet formation and change our understanding of...

Image 1 - Astronomers Release Unprecedented Data Set On Celestial Objects That Brighten And Dim
2012-01-13 04:53:21

Astronomers from the California Institute of Technology (Caltech) and the University of Arizona have released the largest data set ever collected that documents the brightening and dimming of stars and other celestial objects–two hundred million in total. The night sky is filled with objects like asteroids that dash across the sky and others–like exploding stars and variable stars–that flash, dim, and brighten. Studying such phenomena can help astronomers better...

Image 1 - Microlensing Survey Finds A Multitude Of Planets
2012-01-12 03:54:16

[ Watch the Video ] Planets around stars are the rule rather than the exception An international team, including three astronomers from the European Southern Observatory (ESO), has used the technique of gravitational microlensing to measure how common planets are in the Milky Way. After a six-year search that surveyed millions of stars, the team concludes that planets around stars are the rule rather than the exception. The results will appear in the journal Nature on 12 January 2012....

Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less ΔV (change in velocity) than the Moon. In the United States, NASA...

Cerro Tololo Observatory -- astronomical observatory located on Cerro Tololo peak, Chile, with offices in La Serena, about 40 mi (64 km) to the west. Funded by the U.S. National Science Foundation (NSF), it is operated by the Association of Universities for Research in Astronomy (AURA), which also operates such other major national observatories as the Kitt Peak National Observatory in Arizona. The principal instrument is a 158-in. (4-m) reflecting telescope, the largest in 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.
