Monday evening and Tuesday morning will provide the peak time to enjoy the 2010 Geminid meteor shower. Astronomy aficionados in most parts of the world will be able to see what the AFP news agency dubs "the best meteor shower of the year" through December 16. To celebrate the celestial event, NASA conducted a special "Up All Night" online event, and will continue to show live audio and video of the Geminids from the Marshall Space Flight Center in Huntsville, Alabama through Thursday....

By Louis Bergeron, Stanford University Stanford researchers have completed the first successful tests in zero gravity of a canopy for CubeSats "“ the tiny satellites that hitch rides on rockets sending larger satellites into orbit. The goal is to gather data on what happens when micrometeoroids slam into a satellite. Such impacts often knock out electronic equipment on satellites. The encounters are poorly understood, but the canopies could be a first step in eventually building "black...

This month, Comet Hartley 2 has put on a good show for backyard astronomers. The comet's vivid green atmosphere and auburn tail of dust look great through small telescopes, and NASA's Deep Impact/EPOXI probe is about to return even more dramatic pictures when it flies past the comet's nucleus on Nov. 4th. Another kind of show might be in the offing as well. Could this comet produce a meteor shower? "Probably not," says Bill Cooke of NASA's Meteoroid Environment Office, "but the other night...

A small asteroid will fly past Earth early Tuesday within the Earth-moon system. The asteroid, 2010 TD54, will have its closest approach to Earth's surface at an altitude of about 45,000 kilometers (27,960 miles) at 6:50 EDT a.m. (3:50 a.m. PDT). At that time, the asteroid will be over southeastern Asia in the vicinity of Singapore. During its flyby, Asteroid 2010 TD54 has zero probability of impacting Earth. A telescope of the NASA-sponsored Catalina Sky Survey north of Tucson, Arizona...

Summer means fireworks, and here's how to see some of Nature's best displays. Start with a few comets streaking around the solar system, leaving behind dusty trails of gas, ice, rocks and dust. Then find a comfortable nighttime seat on planet Earth as it passes through these dusty comet trails. Finally, sit back and enjoy the show as bits of leftover comet burn up in our atmosphere, creating the celestial displays that we call meteor showers. On Thursday, July 22, astronomer Bill Cooke from...

NASA is evaluating the potential risks to spacecraft posed by the upcoming Draconid meteor shower in 2011, a seven-hour storm of tiny space rocks that could possibly damage major Earth-orbiting spacecraft like the International Space Station. Meteor shower risk assessment is more art than science, and some variations have been predicted for the 2011 Draconids by meteor forecasters. Because of this, spacecraft operators are being notified to weigh out defensive steps. Current forecast models...

A meteor that lit up the Alabama night sky last month now has NASA calling for an all-out search of any meteorites that may have survived the impact. The meteor blazed through the night sky on May 18 and was spotted by cameras at NASA's Marshall Space Flight Center in Huntsville and the Walker County Science Center near Chickamauga, Georgia. Experts have estimated that the chunk of space rock, which hailed from the asteroid belt, weighed around 60 pounds, though it most likely broke into...

Astronomers say they have solved the long-standing mystery over exactly what famed poet Walt Whitman saw streaking through the sky 150 years ago. The researchers discovered that the "strange huge meteor-procession" mentioned in Whitman's noted collection "Leaves of Grass" refers to a rare procession of earth-grazing meteors that occurred in 1860. "Meteor processions are so rare most people have never heard of them," said Texas State University physics professor Donald Olson. "There was one...

Scientists at NASA's Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., have determined that a small object that safely passed Earth on May 21 is more than likely an upper-stage of a rocket that carried a spacecraft on an interplanetary trajectory. "The orbit of this object is very similar to that of the Earth, and one would not expect an object to remain in this type of orbit for very long," said Paul Chodas, a scientist at NASA's Near-Earth Object...

The National Weather Service said that authorities from several Midwestern states were flooded with reports Wednesday night after a giant fireball lit up the evening sky. The NWS in Sullivan, Wisconsin said the fireball was visible for about 15 minutes around 10 p.m. The Quad Cities NWS, which includes parts of Iowa and Illinois, reported that the fireball was seen moving across the northern sky from west to east. "Well before it reached the horizon, it broke up into smaller pieces and was...

Perseids Meteor Shower -- Like most meteor showers, the Perseids are caused by comet debris. As comets enter the inner solar system, they are warmed by the sun and peppered by the solar wind, which produces the familar tails that stretch across the night sky when a bright comet is close to Earth. Comet tails are made of tiny pieces of ice, dust, and rock which are spewed into interplanetary space as they bubble off the comet's nucleus. When Earth encounters these particles on its...

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...
