If you thought that asteroid that scorched through the Russian sky last week was something out of the ordinary, think again. An interactive map that's going viral shows the location, size, and chemical makeup of every asteroid and meteor that has slammed into the Earth since 2,300 BC. If only we had dashboard cameras back then to capture the very first one! The map was created by Javier de la Torre, a blogger in New York and cofounder of mapping company CartoDB.

Shooting stars will brighten skies around the world tonight, offering viewers a chance to make a wish in areas with clear skies. The Geminid meteor shower is one of the year's most spectacular examples of shooting stars, according to the U.S. Naval Observatory, with the best show coming in the hours after midnight. Up to 50 meteors per hour will be visible if skies are clear, according to the Smithsonian Institution.

The annual Leonid meteor shower returns this week, with the peak meteor intensities occurring tonight and Friday night. The optimal viewing periods will begin at 11 p.m. each night, with the number of meteors peaking between midnight and 1:30 a.m. Information about how much meteor activity will be visible from a given location is available at leonid.arc.nasa.gov. Last year's Leonid shower was heavily studied by NASA and revealed some surprises.

The annual Perseid meteor shower will reach its peak Sunday night, with the most activity between midnight and dawn. The combination of a moonless night and a peak that favors North America should make for excellent viewing, experts said. The meteors will appear in all parts of the sky, but experts suggest looking toward the darkest areas. The shower will continue for two more weeks.

There will be something for everybody in the nighttime sky during the next few weeks, including a meteor shower this weekend and a total eclipse of the moon next week. August will also bring the astronomical highlight of the year when the aging Voyager 2 spacecraft zips over the cloud tops of Neptune on the evening of Aug. 24.

Space agency officials on Friday postponed the shuttle Discovery's satellite-delivery mission for a third time to avoid the annual Perseids meteor shower, which astronomers say could be the most spectacular meteor shower in 130 years. National Aeronautics and Space Administration spokesman James Hartsfield said shuttle managers at Johnson Space Center put off Discovery's launch, which had been scheduled for Wednesday, until at least Aug. 12.

A huge fireball was spotted over northwestern Oregon and southern Washington Wednesday afternoon, and one expert said it probably was an unusually large meteor. A motorcyclist traveling on a coastal highway reported the sighting to the U.S. Coast Guard about 1:30 p.m. Later, dozens of witnesses called in reports to radio stations from the coast to south-central Washington.

The 10-ton meteor that streaked into Earth's atmosphere at 40,000 mph and exploded above the Russian city of Chelyabinsk was a reminder that the universe is not such a hospitable place. Still, though hundreds of people were injured and thousands of windows were shattered, no one died and repairs can be made. By comparison, the terrestrial havoc wrought by Hurricane Sandy in the northeastern United States was far more devastating. In the movies, when humanity is faced with imminent doom, whether from a massive asteroid or an invasion of space monsters, the people of the world forget their differences, band together and save themselves.

The meteor that blazed over a portion of Russia early Friday, blasting windows and triggering car alarms with a series of explosive booms, was not related to asteroid 2012 DA14 and had a very different trajectory, according to scientists at NASA. As numerous videos of the event were viewed worldwide, experts said the meteor was likely about one-third the size of 2012 DA14, too small to track and therefore a surprise. The largest noise heard on video of the event was likely the main mass of the meteor exploding 100,000 to 150,000 feet above the Earth's surface, and not a sonic boom, scientists said.

A massive bombardment of meteorites billions of years ago could have brought in enough water and carbon dioxide to jump-start the chemistry that let the Earth develop into the garden spot of our solar system. By studying meteorites and other evidence from this bombardment, a team of researchers at Imperial College in England has calculated that the meteorites could have carried in as much as 10 billion tons of water vapor and carbon dioxide to the young Earth every year for millions of years.
