[ Watch the Video: ScienceCasts: 2012 Perseid Meteor Shower ] April Flowers for redOrbit.com - Your Universe Online Every year in August, the Perseid Meteor shower is visible to the naked eye and is a favorite for professional and amateur astronomers alike. The Perseid shower has it all. It offers a consistently high rate of meteors, it produces more bright, visible meteors than any other shower, it happens in August when many people are on vacation, and it happens at a time when...

The Perseid meteor shower is peaking around August 12 through the 13th, but this year it will have to pierce through the sky against a full Moon. The Perseid meteor shower has been observed for about 2000 years and is associated with the comet Switf-Tuttle. The shower is visible from mid-July each year, with the peak in activity being between August 9 and 14, depending on the particular location of the stream. The rate of meteors reaches 60 or more per hour during the peak hours, and they...

Dr. Brian Geoffrey Marsden passed away Thursday, Nov. 18 at the age of 73 following a prolonged illness. He was a Supervisory Astronomer at the Smithsonian Astrophysical Observatory and Director Emeritus of the Minor Planet Center. "Brian was one of the most influential comet investigators of the twentieth century," said Charles Alcock, Director of the Harvard-Smithsonian Center for Astrophysics, "and definitely one of the most colorful!" Dr. Marsden specialized in celestial mechanics and...

Perseid Meteor Shower: Afternoon Chat, Then Up All Night! Looking for a little excitement as the summer draws to a close? This year's Perseid meteor shower peaks on Aug. 12-13, and it promises to be one of the best displays of the year. If forecasters are correct, the shower should produce a peak display of at least 80 meteors per hour. A waxing crescent moon will set before the shower becomes active, setting a perfect stage for meteor watching -- weather permitting, of course! On Thursday,...

The annual Perseid meteor shower this week is predicted to be a grand event with peak viewing times Thursday night August 12 into the early pre-dawn hours Friday August 13. According to NASA, the shower may produce a display of up to 80 meteors an hour. For best views of the event, experts are urging spectators to get as far away from city lights as possible. The Perseid meteor shower has been ongoing for about a week and peak times were set for Wednesday night into Thursday morning, and...

You know it's a good night when a beautiful alignment of planets is the second best thing that's going to happen. Thursday, August 12th, is such a night. The show begins at sundown when Venus, Saturn, Mars and the crescent Moon pop out of the western twilight in tight conjunction. All four heavenly objects will fit within a circle about 10 degrees in diameter, beaming together through the dusky colors of sunset. No telescope is required to enjoy this naked-eye event: sky map. The planets...

Earth is entering a stream of dusty debris from Comet Swift-Tuttle, the source of the annual Perseid meteor shower. Although the shower won't peak until August 11th and 12th, the show is already getting underway. Don't get too excited, cautions Bill Cooke of NASA's Meteoroid Environment Office. "We're just in the outskirts of the debris stream now. If you go out at night and stare at the sky, you'll probably only see a few Perseids per hour." This will change, however, as August unfolds....

Mark your calendar: The 2008 Perseid meteor shower peaks on August 12th and it should be a good show. "The time to look is during the dark hours before dawn on Tuesday, August 12th," says Bill Cooke of NASA's Meteoroid Environment Office at the Marshall Space Flight Center. "There should be plenty of meteors--perhaps one or two every minute." The source of the shower is Comet Swift-Tuttle. Although the comet is far away, currently located beyond the orbit of Uranus, a trail of debris from the...

Got a calendar? Circle this date: Sunday, August 12th. Next to the circle write "all night" and "Meteors!" Attach the above to your refrigerator in plain view so you won't miss the 2007 Perseid meteor shower. "It's going to be a great show," says Bill Cooke of NASA's Meteoroid Environment Office at the Marshall Space Flight Center. "The Moon is new on August 12th--which means no moonlight, dark skies and plenty of meteors." How many? Cooke estimates one or two Perseids per minute at the...

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...

Leonids Meteor Shower -- The Leonids are a prolific meteor shower associated with the comet Tempel-Tuttle. The meteor stream is viewable every year around November 17 and is thought to be comprised of particles ejected by the comet as it passes by the Sun. When the Earth moves through the meteor stream, the meteor shower is visible. The Leonids get their name from usually making their appearance in or near the constellation Leo. The Leonids are famous because their meteor showers,...

Comet Tempel-Tuttle -- Comet Tempel-Tuttle is an inherently faint and typically unspectacular comet that has only been observed on a few apparitions over the past 600 years. Its most recent apparition was in 1998, when it reached perihelion on February 28. As expected, it showed little activity, and only a small tail. However, further inspection shows that this comet is more interesting than the first glance suggests. Its orbit is oriented in such a way that the comet makes a...
