Newfound Asteroid Will Fly Close by Earth Thursday



A newly discovered asteroid will zip close by Earth Thursday, but poses no threat of crashing into our planet even though it is passing within the orbit of the moon.
The asteroid, called 2010 GA6, is a relatively small space rock about 71 feet (22 meters) wide and was discovered by astronomers with the Catalina Sky Survey in Tucson, Az. The space rock will fly within the orbit of the moon when it passes Earth Thursday at 7:06 p.m. EDT (2306 GMT), but NASA astronomers said not to worry...the planet is safe.
"Fly bys of near-Earth objects within the moon's orbit occur every few weeks," said Don Yeomans of NASA's Near-Earth Object Office at the Jet Propulsion Laboratory in Pasadena, Calif., in a statement.
At the time of its closest pass, asteroid 2010 GA6 will be about 223,000 miles (359,000 km) from the Earth. That's about nine-tenths the distance between Earth and the moon [more asteroid photos].
The space rock is not the first asteroid to swing close by Earth this year.
In January, the small asteroid 2010 AL30 passed within 80,000 miles (130,000 km) when it zipped by. Other space rocks have flown past Earth at more comfortable distances greater than several hundred thousand miles.
NASA routinely tracks asteroids and comets that may fly near the Earth with a network of telescopes on the ground and in space. The agency's Near-Earth Object Observations program, more commonly known as Spaceguard, is responsible for finding potentially dangerous asteroids and studying their orbits to determine if they pose a risk of hitting the Earth.
NASA's latest space telescope, the Wide-field Infrared Survey Explorer (WISE) launched in December, has been given the task of hunting new asteroids that were previously undetectable because they shine only in the infrared range of the light spectrum.
So far, the WISE telescope has been discovering dozens of previously unknown asteroids every day. Some of those space rocks have been tagged for closer analysis since they may be potentially hazardous to Earth, WISE mission scientists have said.

Last Chance to Get a Good Look at Mars Until 2012



On Thursday night, March 25, many people may look up at the sky and ask the question, "What's that bright star next to the moon?"
The answer for Thursday night is Mars, but that answer changes night by night as the moon travels along the ecliptic, the path the sun, moon and planets follow across the sky. If you ask the question again on Monday night, March 29, the answer will be the ringed planet Saturn.
Such conjunctions of the moon and planets are regular reminders of how rapidly the moon moves across the sky.
Mars was in opposition to the Sun on Jan. 29, when it appeared 14 arcseconds in diameter, 1/120 of the diameter of the moon. Two months later, it is much farther away, and has shrunk to only 10 arcseconds in diameter.
This will be your last chance to get a good look at Mars until it approaches the Earth again in 2012 [see more Mars photos].
The sky these spring evenings presents a striking contrast between its western half, filled with the bright stars and constellations of winter, and its eastern half, with Regulus the only bright star. Mars sits in solitary splendor in Cancer, one of the most insignificant zodiac constellations, just above the plane of the Milky Way.
But there is much lurking beyond the dim stars of spring, for we are entering the realm of the galaxies. The constellation Leo alone contains five of the brightest galaxies in Charles Messier's famous 18th century catalog of deep sky objects.
When we look towards Leo, we are looking above the plane of our Milky Way galaxy at the depths of intergalactic space, unhindered by the clouds of dust and gas which fill our galaxy.

Tsunami from Chile quake reaches Japan



TOKYO – The first tsunami from Chile's earthquake has hit Japan's outlying islands, but the initial waves are small.
Japan's Meteorological Agency said the first tsunami to reach Japan after the magnitude 8.8 quake off Chile was recorded in the Ogasawara islands early Sunday afternoon. It was just 10 centimeters high. There were no reports of damage.
Officials warned that bigger waves could reach Japan's main islands, and kept up their alert for the nation's Pacific coastline.
Japan put all of its eastern coastline on tsunami alert Sunday and ordered hundreds of thousands of residents in low-lying areas to seek higher ground as waves generated by an earthquake off Chile raced across the Pacific at hundreds of miles (kilometers) per hour.
THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP's earlier story is below.
TOKYO (AP) — Japan's Meteorological Agency has warned that a "major" tsunami of up to 9 feet (3 meters) could hit northern coastal areas within the next few hours following a massive earthquake in Chile.
The agency issued the tsunami alert Sunday morning for its entire Pacific coast. The tsunami was expected to be biggest in the north, with waves of 6 feet (2 meters) or less expected along other coastal areas.
The tsunami was expected to hit northern areas about 1:30 p.m. local time (0430 GMT).
The agency urged residents in coastal areas to head quickly to higher ground.
