Wallaby And Dingo Telescopes Set To Find 700,000 New Galaxies In 2013
2012-12-31 06:55:59

Lawrence LeBlond for redOrbit.com - Your Universe Online Australian astronomers are expecting two sky surveys will be on par to discover some 700,000 new galaxies in 2013. The sky surveys, named Wallaby and Dingo, were officially opened earlier this year as part of the Australian Square Kilometer Array Pathfinder (Askap). The $105 million Askap is located in a remote desert region of Western Australia, roughly 200 miles from Geraldton. Askap consists of 36 dishes, each 39 feet wide,...

Stellar Patrons Of The Milky Way Bar Identified By Astronomers
2012-12-19 15:03:31

SDSS-III Forget the restaurant at the end of the Universe – astronomers now have the clearest understanding yet of the bar at the center of the Milky Way. Scientists with the Sloan Digital Sky Survey III (SDSS-III) have announced the discovery of hundreds of stars rapidly moving together in long, looping orbits around the center of our Galaxy. "The best explanation for their orbits is that these stars are part of the Milky Way bar," says David Nidever, a Dean B. McLaughin Fellow...

Lawrence Berkeley National Laboratory $2.1 Million Grant to Berkeley Center for Cosmological Physics advances dark energy research at UC Berkeley and Berkeley Lab A $2.1 million grant from the Gordon and Betty Moore Foundation to the University of California at Berkeley, through the Berkeley Center for Cosmological Physics (BCCP), will fund the development of revolutionary technologies for BigBOSS, a project now in the proposal stage designed to study dark energy with unprecedented...

New Australian Telescope Could Find 700,000 Galaxies
2012-11-09 19:34:57

Lee Rannals for redOrbit.com — Your Universe Online Australian researchers wrote in a paper published Sunday in the Monthly Notices of the Royal Astronomical Society that there could be another 700,000 galaxies out there ready to be found by a new telescope. The researchers have combined computer simulations with CSIRO´s next-generation Australian Square Kilometre Array Pathfinder (ASKAP) specifications to predict the new telescope's extraordinary capabilities....

Dark Energy Camera Dedication Amping Up Next Week
2012-11-02 12:51:23

Lee Rannals for redOrbit.com — Your Universe Online Today marks the 50th anniversary celebration of Cerro Tololo Inter-American Observatory (CTIO), while next week is the dedication of a new instrument for the observatory. The Dark Energy Camera was installed on the Victor M. Blanco telescope at CTIO, and it will be conducting powerful surveys by collecting light from 100,000 galaxies located up to 8 billion light years away. The camera has 62 charged-coupled devices with an...

Star Stream Serves As Light Snack For Growing Milky Way
2012-10-27 05:56:42

redOrbit Staff & Wire Reports - Your Universe Online The Milky Way apparently has one voracious appetite, as researchers from a prominent American university have discovered our home galaxy slowly consuming the remnants of an ancient star cluster. Astronomers from Yale University used the Sloan Digital Sky Survey to locate a stream of stars being slowly ingested by the galaxy. While researchers have previously discovered evidence that the Milky Way has gobbled up dwarf galaxies,...

Distant Quasar Shows No Sign Of Feeding On Galaxy Of Stars
2012-10-24 12:05:36

Lee Rannals for redOrbit.com — Your Universe Online While looking at one of the most distant quasars in the universe, astronomers were surprised to not see an underlying host galaxy of stars feeding it. NASA said the best explanation is that the galaxy is shrouded in so much dust that the stars are completely hidden everywhere. As stars aged and burned out in the early universe, they filled interstellar space with dust as they lost their atmosphere. The quasar dates back to an...

Lost Asteroid Rediscovered By Amateur Astronomer
2012-10-13 05:05:52

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) reports that it has rediscovered an asteroid that was once lost through the agency's space hazards program. Potentially Hazardous Asteroid 2008SE85 was first discovered back in September 2008 by the Catalina Sky Survey, and was observed by a few observatories the following month. However, no one since then has observed the object, and predictions for its current position had become so inaccurate that...

Ancient Starlight Recorded By Dark Energy Camera
2012-09-18 04:19:18

April Flowers for redOrbit.com - Your Universe Online Approximately 8 billion years ago, the light from distant galaxies began streaming towards Earth. Now, at a mountaintop observatory in Chile, the newly constructed Dark Energy Camera (DECam), the most powerful sky-mapping machine ever created, has captured that ancient starlight and recorded it for the first time. Early on September 12, 2012, the DECam, mounted atop the Victor Blanco Telescope at the Cerro Tololo Inter-American...

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...
