A free application using data from the UA's Catalina Sky Survey reveals a night sky that is surprisingly busy You're at a party on the patio where everyone is marveling at the clear, star-studded night sky. With a new application for the iPhone or iPod Touch, you can impress them with pictures of a supernova exploding in Orion, a star moving through Cassiopeia, or a cloud of interstellar dust flaring up while being gobbled by a black hole. The application, called Transient Events, uses...

A newly discovered asteroid, 2010 GA6, will safely fly by Earth this Thursday at 4:06 p.m. Pacific (23:06 U.T.C.). At time of closest approach 2010 GA6 will be about 359,000 kilometers (223,000 miles) away from Earth - about 9/10ths the distance from to the moon. The asteroid, approximately 22 meters (71 feet) wide, was discovered by the Catalina Sky Survey, Tucson, Az. "Fly bys of near-Earth objects within the moon's orbit occur every few weeks," said Don Yeomans of NASA's Near-Earth Object...

Discovery may be in front of your home computer. As technology increases the amount of new information available in various fields of science such as oceanography, astronomy and ecology, researchers are turning to citizen scientists to unlock the data. In a study funded by the National Science Foundation's (NSF) Directorate for Education & Human Resources, researchers are studying an online suite of citizen-science projects called Zooniverse to determine the implications of public...

Imagine you're a Brontosaurus with your face in a prehistoric tree top, munching on fresh leaves. Your relatives have ruled planet Earth for more than 150 million years. Huge and strong, you feel invincible. You're not. Fast forward about 65 million years. A creature much smaller and weaker dominates the Earth now, with brains instead of brawn. Its brain is a lot larger than yours relative to its body size "“ plenty big enough to conceive a way to scan the cosmos for objects like the...

A previously undiscovered asteroid passed close to the Earth on Monday after being spotted just 15 hours before the close encounter. The Catalina Sky Survey discovered the asteroid about 15 hours before it came within 8,700 miles from Earth, making it the third-closest known non-impacting asteroid in documented history. Scientists said on average, asteroids the size of 2009 VA come this close to Earth about twice a year, while they impact about once every five years. Soon after 2009 VA was...

The Catalina Sky Survey detects potentially hazardous asteroids and comets. Now a spin-off survey is finding a windfall of "optical transients" in the same data. Astronomers have been mining a mother lode of astronomical data from the University of Arizona's Catalina Sky Survey and finding more "optical transients" than they can characterize during the past 17 months. They have found more than 700 unique "optical transients," or objects that change brightness on time scales of minutes to...

In the 2005 NASA Authorization Act, Congress mandated that by 2020 NASA should be capable of detecting at least 90 percent of objects over 140 meters wide in the vicinity of Earth's orbit. NEAR-EARTH OBJECT SURVEYS AND HAZARD MITIGATION STRATEGIES, an interim report of a congressionally mandated study by the National Research Council, examines NASA's current ability to survey and detect these near-Earth objects. A final report will address hazard mitigation and make recommendations on ways to...

WASHINGTON, Aug. 5 /PRNewswire-USNewswire/ -- NASA's Spitzer Space Telescope is starting a second career and taking its first shots of the cosmos since warming up. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The infrared telescope ran out of coolant May 15, 2009, more than five-and-one-half-years after launch. It has since warmed to a still-frosty 30 degrees Kelvin (about minus 406 degrees Fahrenheit). New images taken with two of Spitzer's infrared detector channels...

A small asteroid will fly past Earth early tomorrow morning (Wed., March 18). The asteroid, 2009 FH, is about 50 feet (15 meters) wide. Its closest approach to Earth will occur at 5:17 a.m. PDT (8:17 a.m. EDT, 12:17 UTC) at an altitude of about 49,000 miles (79,000 kilometers). "This asteroid flyby will be a good viewing opportunity for both professional and amateur astronomers," said Don Yeomans of the Near-Earth Object Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "The...

Italian astronomer Andrea Boattini discovered six comets in 2008 while tracking cosmic debris throughout the solar system at Mount Lemmon Observatory in Arizona. And though it isn't a world record, the discovery of six comets in one year is the most found by an Italian astronomer since the mid-19th Century. The Catalina Sky Survey is part of a NASA project to find and track near-Earth objects (NEOs) using two telescopes in Arizona and one in Australia. In 1998, NASA started compiling an...

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...
