A Call To Back The Advanced Technologies Large Aperture Space Telescope
2014-06-23 03:25:13

Royal Astronomical Society In the nearly 25 years since the launch of the Hubble Space Telescope (HST), astronomers and the public alike have enjoyed ground-breaking views of the cosmos and the suite of scientific discoveries that followed. The successor to HST, the James Webb Telescope should launch in 2018 but will have a comparatively short lifetime. Now Prof Martin Barstow of the University of Leicester is looking to the future. In his talk at the National Astronomy Meeting (NAM...

Star Measurement Made Easier With A Novel Spectral Ruler
2014-06-23 14:32:00

Brett Smith for redOrbit.com - Your Universe Online Being hailed as a critical first step in a massive attempt to map the Milky Way, a team of European astronomers has devised a novel way to categorize stars based on their metallic composition, according to a new paper published in the journal Astronomy & Astrophysics. The study team developed their ‘spectral ruler’ by selecting 34 'benchmark' stars to characterize the distinct kinds of stellar groups in our galaxy, such as hot...

asteroid 2011 MD spitzer
2014-06-19 13:09:44

Whitney Clavin, Jet Propulsion Laboratory Astronomers using NASA's Spitzer Space Telescope have measured the size of an asteroid candidate for NASA's Asteroid Redirect Mission (ARM), a proposed spacecraft concept to capture either a small asteroid, or a boulder from an asteroid. The near-Earth asteroid, called 2011 MD, was found to be roughly 20 feet (6 meters) in size, and its structure appears to contain a lot of empty space, perhaps resembling a pile of rubble. Spitzer's infrared vision...

NASA's New Horizons To Use Hubble In Search Of Deep Space Object
2014-06-16 14:18:13

Alan McStravick for redorbit.com - Your Universe online Update (June 17, 2014): A previous version of this article stated that Charon was discovered by the Hubble Telescope. In fact, Charon was first discovered in 1978 by James Christy of the United States Naval Observatory. The Hubble Space Telescope has been in near-Earth orbit for 24 years. While its early days were marred by launch delays and the embarrassment of a major flaw in its crucial mirror, since correction the telescope has...

WASHINGTON, June 16, 2014 /PRNewswire-USNewswire/ -- After careful consideration and analysis, the Hubble Space Telescope Time Allocation Committee has recommended using Hubble to search for an object the Pluto-bound NASA New Horizons mission could visit after its flyby of Pluto in July 2015. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The planned search will involve targeting a small area of sky in search of a Kuiper Belt object (KBO) for the outbound spacecraft to...

Heart Of James Webb Space Telescope Lowered Into Chamber
2014-06-16 03:43:11

Laura Betz, NASA Engineer Jack Marshall held his breath. The "heart" of the James Webb Space Telescope hung from a cable 30 feet in the air as it was lowered slowly into the massive thermal vacuum chamber at NASA's Goddard Space Flight Center in Greenbelt, Maryland. This "heart" of Webb is called the ISIM or Integrated Science Instrument Module, which along with its thermal vacuum test frame and supporting hardware, weighs about as much as an elephant. Within this test frame, ISIM sits...

Gamma ray burst buried in dust
2014-06-12 04:59:01

redOrbit Staff & Wire Reports - Your Universe Online For the first time ever, scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered molecular gas in galaxies that had once been rocked by gamma ray bursts, according to new research published Wednesday in the journal Nature. The new observations reveal that the molecular gas, which serves as the fuel for the star formation process, was concentrated towards the center of the galaxies, the study...

Pulsating X-rays Allow XMM-Newton To Reveal A Mysterious Star
2014-06-04 03:32:58

ESA XMM-Newton has revealed a unique star. It is a celestial chimera with the body of a normal massive star yet the magnetic field of a dead, stellar dwarf. This makes it a singular object among the billions of known stars. The race is now on to understand why it behaves in this way because the work hints at an unanticipated link between the deep interior of a star and the surrounding atmosphere. The star is known only by its catalogue designation, Xi1 Canis Majoris. It lies some...

Alan McStravick for redOrbit.com - Your Universe Online The European Space Agency (ESA) has recently announced the successful on-Earth testing of its Solar Orbiter's protective heat shield. The test, conducted at the ESA's Technical Center in Noordwijk subjected a 'structural-thermal' version of the craft's sunshield to an artificial Sun for a period of two weeks in their vacuum chamber - the largest in Europe. The results prove the shield will have no issue with the extreme temperatures...

hubble evolving Universe

April Flowers for redOrbit.com - Your Universe Online In a new study called the Ultraviolet Coverage of the Hubble Ultra Deep Field (UVUDF) project, the most comprehensive and colorful picture of the evolving universe has been captured by astronomers using the Hubble Space Telescope. Prior to the UVUDF study, astronomers knew a great deal about star formation that occurred in nearby galaxies, thanks to UV telescopes such as NASA's GALEX observatory. The astronomers were also able to...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
