Citizen Scientists Wanted To Observe Asteroid Blot Out A Star
2014-03-17 08:49:55

Lawrence LeBlond for redOrbit.com - Your Universe Online Millions of Americans may be able to catch a space rock darkening the night sky this Thursday as the brightest visible star vanishes before our very eyes. If you live in the Northeast and the skies are clear, you may want to go out and look up at around 2 a.m (EDT) on March 20. If by chance the skies are clear, then you will want to look to the western skies toward the constellation Leo and hunt down the bright star known as...

Strawberry Moon Eclipse A Week Away
2012-05-30 03:31:42

Lee Rannals for RedOrbit.com [ Watch the Video ] A strawberry moon may sound like a delicious dessert to some, but for astronomers it´s a dish that will fulfill their lunar eclipse appetite next Monday. At 3:00 a.m. Pacific Daylight Time on June 4, the Moon will pass directly behind the Earth, producing the first lunar eclipse of 2012. The eclipse will be visible in North and South America, Australia, eastern parts of Asia, and across the Pacific Ocean. The Strawberry...

NASA officials have announced plans to use the moon like a mirror in order to allow them to see the forthcoming transit of Venus across the face of the sun on June 5 and 6, the U.S. space agency announced in a Friday press release. The seemingly unorthodox technique is necessary because the Hubble Space Telescope, which will be used to observe the transit, cannot look at the sun directly. To work around that issue, astronomers will be pointing the telescope at our planet's satellite, using...

Rare Venus Event Expected In June
2012-05-01 08:39:53

A once-in-a-lifetime event is on its way -- an event that hasn´t occurred since 1882 and will not occur again until 2117 -- and will be a spectacular event for millions of people all around the world. The Transit of Venus, as it is called, occurs when the planet passes across the face of the Sun. It is viewable from Earth as a small black dot on the solar surface and takes about six hours to complete its transit. The event will occur on June 5 and 6 and will be visible across much of...

On the evening of July 3 at 11:05:30 p.m. EDT -- at a distance of 280 million miles into space that poses no threat to Earth -- 52 Europa will pass in front of star TYC 0292-00339-1 in the constellation Virgo. The asteroid will eclipse the star's light for 17.9 seconds in a process known as occultation. Here on Earth, astronomers can measure the exact length of time the star's light is blocked and use those calculations to help verify the size of 52 Europa. They'll also have a live Web chat...

MESSENGER's Mercury Laser Altimeter (MLA) in its first 2 months of operation has already built up a grid of ground tracks that span most of Mercury's surface north of the equator (Figure 1). These data will provide a very good measure of the shape of the planet's northern hemisphere. The shape of a planet carries a record of all of the interior dynamical and geological processes that have modified the surface. Signals from MLA's laser reflected from the surface can be recovered whenever the...

Occultation provided enough data to determine the KBO's size and albedo Until now, astronomers have used telescopes to find Kuiper Belt objects (KBOs), moon-sized bodies, and obtain their spectra to determine what types of ices are on their surface. They have also used thermal-imaging techniques to get a rough idea of the size of KBOs, but other details have been difficult to glean. While astronomers think there are about 70,000 KBOs that are larger than 100 kilometers in diameter, the...

When the sun sets on Saturday, March 20th, a special kind of night will fall across the Earth. It's an equal night. Or as an astronomer would say, "it's an equinox." It's the date when the sun crosses the celestial equator heading north. Spring begins in one hemisphere, autumn in the other. The day and night are of approximately equal length. To celebrate the occasion, Nature is providing a sky show. It begins as soon as the sky grows dark. The Moon materializes first, a fat crescent hanging...

NASA's new exoplanet-hunting Kepler space telescope has detected the atmosphere of a known giant gas planet, demonstrating the telescope's extraordinary scientific capabilities. The discovery will be published Friday in the journal Science."As NASA's first exoplanets mission, Kepler has made a dramatic entrance on the planet-hunting scene," said Jon Morse, director of the Science Mission Directorate's Astrophysics Division at NASA Headquarters in Washington. "Detecting this planet's...
