10-ton rock responsible for fireball in Western Canada last week Investigation of the fireball that lit up the skies of Alberta and Saskatchewan on November 20 has determined that an asteroid fragment weighing approximately 10 tons entered the Earth's atmosphere over the prairie provinces last Thursday evening. And University of Calgary researcher Alan Hildebrand has outlined a region in western Saskatchewan where chunks of the desk-sized space rock are expected to be found. The fireball...

Experts say a flaming ball of fire was seen for more than 400 miles Thursday during one of the biggest meteor events to happen in Canada this year. Scientists say they hope to find remnants of the meteor, which streaked through the darkening skies over Alberta and Saskatchewan at about 5:30 p.m. Calgary time. They estimate it weighed between one and ten tons and shone brightly enough to be seen over an area 700 km (435 miles) wide. "It was somewhere between the size of a chair to the size...

It started out as a normal day. NASA astronomer and meteor expert Bill Cooke woke up, dressed, and went to his office at the Marshall Space Flight Center. Colleagues greeted him as usual, there was no hum of excitement. And then he checked his email. "That's how I found out"”I'd slept through a meteor outburst!" During the dark hours before dawn on Sept. 9, 2008, a surprising flurry of meteors had showered the skies above Huntsville, Alabama. More than two dozen of them were fireballs...

For the second time this year, The University of Western Ontario Meteor Group has captured incredibly rare video footage of a meteor falling to Earth. The team of astronomers suspects the fireball dropped meteorites in a region north of Guelph, Ontario, Canada, that may total as much as a few hundred grams in mass. The Physics and Astronomy Department at Western has a network of all-sky cameras in southern Ontario that scan the sky monitoring for meteors. On Wednesday, October 15 at 5:28...

Boulder-sized Asteroid Will Burn Up in Earth's Atmosphere Tonight A tiny asteroid discovered just hours ago at an Arizona observatory will enter Earth's atmosphere harmlessly at approximately 10:46 p.m. Eastern time tonight (2:46 a.m. Greenwich Mean Time). There is no danger to people or property since the asteroid will not reach the ground. It is between 3 and 15 feet (1-5 m) in diameter and will burn up in the upper atmosphere, well above aircraft heights. A brilliant fireball will be...

There's more than one way to watch a meteor shower. One, the old-fashioned way: Find a dark place with starry skies and count the meteors streaking overhead. Two, the new way: Find a dark place with starry skies and then completely ignore the meteors. Instead, watch the Moon. That's where the explosions are. On August 9th, a pair of amateur astronomers on opposite sides of the United States did it the new way. With the Perseid meteor shower just underway, they fixed their cameras on the Moon...

Not so long ago, anyone claiming to see flashes of light on the Moon would be viewed with deep suspicion by professional astronomers. Such reports were filed under "L" "¦ for lunatic. Not anymore. Over the past two and a half years, NASA astronomers have observed the Moon flashing at them not just once but one hundred times. "They're explosions caused by meteoroids hitting the Moon," explains Bill Cooke, head of NASA's Meteoroid Environment Office at the Marshall Space Flight Center...

Astronomers from The University of Western Ontario in London, Ontario, have captured rare video of a meteor falling to Earth.The Physics and Astronomy Department at Western has a network of all-sky cameras in Southern Ontario that scan the sky monitoring for meteors. Associate Professor Peter Brown, who specializes in the study of meteors and meteorites, says that Wednesday evening (March 5) at 10:59 p.m. EST these cameras captured video of a large fireball and the department has also...

By Bill Kemp BLOOMINGTON - It was one of the greatest natural light shows in recorded human history. During the predawn hours of Nov. 13, 1833, the heavens lit up like a Fourth of July sparkler as tens of thousands of meteors streaked through the darkened sky. Early McLean County settler Robert Dickerson said it was like watching "showers of fiery rain falling to the ground." Reliable accounts of the event boggle the mind. A.C. Twyning of West Point, N.Y., for instance, estimated the rate...

Most people appreciate lunar eclipses for their silent midnight beauty. NASA astronomer Bill Cooke is different: he loves the explosions. On Tuesday morning, Aug. 28th, Earth's shadow will settle across the Moon for a 90-minute total eclipse: full story. In the midst of the lunar darkness, Cooke hopes to record some flashes of light--explosions caused by meteoroids crashing into the Moon and blasting themselves to smithereens. "The eclipse is a great time to look," says Cooke, who heads up...

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...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
