Radar imaging at NASA's Goldstone Solar System Radar in the California desert on Dec. 11 and 12, 2010, revealed defining characteristics of recently discovered asteroid 2010 JL33. The images have been made into a short movie that shows the celestial object's rotation and shape. A team led by Marina Brozovic, a scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif., made the discovery. "Asteroid 2010 JL33 was discovered on May 6 by the Mount Lemmon Survey in Arizona, but prior to...

Exactly one week before the world gets a new look at comet Hartley 2 via NASA's EPOXI mission, observations of the comet by the Arecibo Planetary Radar in Puerto Rico have offered scientists a tantalizing preview. "It kind of looks like a cross between a bowling pin and a pickle," said EPOXI project manager Tim Larson of NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Only it's about 14-thousand-times larger and hurtling through space at 23 miles per second." A new image is online at...

Idle computers are the astronomers' playground: Three citizen scientists "“ a German and an American couple "“ have discovered a new radio pulsar hidden in data gathered by the Arecibo Observatory. This is the first deep-space discovery by Einstein@Home, which uses donated time from the home and office computers of 250,000 volunteers from 192 different countries. (Science Express, Aug. 12, 2010.)The citizens credited with the discovery are Chris and Helen Colvin, of Ames, Iowa and...

Key observations of an asteroid with a slight chance of hitting Earth may have to be shuttered in light of budget cuts, officials at a Puerto Rico observatory reported on Thursday. Officials at the Arecibo Observatory, who are tracking the orbit of an asteroid that could possibly make impact in 2036, are facing funding cuts starting in 2011. They are seeking to complete radar measurements in early 2013 that they believe will prove the asteroid, Apophis, will miss Earth. However, in order to...

A new report from the National Research Council lays out options NASA could follow to detect more near-Earth objects (NEOs) "“ asteroids and comets that could pose a hazard if they cross Earth's orbit. The report says the $4 million the U.S. spends annually to search for NEOs is insufficient to meet a congressionally mandated requirement to detect NEOs that could threaten Earth. Congress mandated in 2005 that NASA discover 90 percent of NEOs whose diameter is 140 meters or greater by...

The world's largest and longest-running volunteer computing project, SETI@home, celebrates its tenth anniversary this month with 140,000 participants and 235,000 computers powering the search for intelligent signals from space. No extraterrestrials have been found yet. But the project will hold a day-long symposium at the University of California, Berkeley's Space Sciences Laboratory on May 21 to celebrate the birthday and discuss the future of a project that still excites the public and has...

The desire to contact intelligent life on other planets is much older than the UFO craze and the SETI movement. Several 19th century scientists contemplated how we might communicate with possible Martians and Venusians. These early proposals - which predate by 150 years the first extraterrestrial message that was sent in 1974 - were based on visual signals, as the invention of radio was still decades away. In fact, as history shows, ideas for interplanetary communication have largely been...

Five astronomy students at the University of Wisconsin-Madison have carried their research to unexpected heights -- they found a galaxy. They made their improbable find in a most improbable way, using the world's largest radio telescope, the Arecibo Observatory in Puerto Rico. The students told the Wisconsin Sate Journal that their good fortune was not expected when they signed up for a research methods class being taught by UW-Madison astronomer Snezana Stanimirovic. But the astronomer had...

On May 22, Arecibo Observatory in Puerto Rico joined other telescopes in North America, South America, Europe and Africa in simultaneously observing the same targets, simulating a telescope more than 6,800 miles (almost 11,000 kilometers) in diameter.The telescopes are all members of the Express Production Real-time e-VLBI Service (EXPReS) project, and May 22 marked a live demonstration of their first four-continent, real-time, electronic Very Long Baseline Interferometry (e-VLBI)...

Once considered just your average single asteroid, 2001 SN263 has now been revealed as the first near-Earth triple asteroid ever found. The asteroid -- with three bodies orbiting each other -- was discovered this week by astronomers using the radar telescope at the National Science Foundation's (NSF) Arecibo Observatory in Puerto Rico. Cornell and Arecibo astronomer Michael C. Nolan said he and his colleagues made the discovery when they obtained radar images Feb. 11. The group subsequently...

Arecibo Observatory -- The Arecibo Observatory is part of the National Astronomy and Ionosphere Center (NAIC), a national research center operated by Cornell University under a cooperative agreement with the National Science Foundation (NSF). The NSF is an independent federal agency whose aim is to promote scientific and engineering progress in the United States. NSF funds research and education in most fields of science and engineering. Additional support is provided by the National...
