Fire in the Sky
Resident astronomer Scott Young said the museum has received at least 100 calls about an eerie green light that appeared in the sky on Friday night. Young believes the object was either a small asteroid or a chunk of comet that shattered into several pieces after burning up in the Earth's atmosphere.
"The receptionist is doing nothing but answering calls and taking numbers right now and I think I'm up to 180 e-mails," he said. "Lots of people saw it."
"Anyone who saw it should count themselves as lucky -- they are probably not going to see another one like that in their lifetime," Scott Young said.
Each year, about 500 meteors reach the earth, but only five or six of these actually reach the hands of scientists for scientific studies.
Most histories of the mission end right there, with Mariner 4 buzzing Mars - "the first spacecraft to visit the red planet" - and throwing cold water on a lot of good science fiction. But there's more to the story. After the flyby, something strange happened to Mariner 4, setting the stage for a 40-year mystery.
Last month, the asteroid 2004 XP14 passed some 268,873 miles (432,000 kilometers) from Earth. That distance is slightly greater than that between the Earth and the moon.
Astronomers called it "a close shave in the vastness of outer space."
It may not last very long, but could produce a bevy of bright, swift shooting stars for favorably positioned skywatchers. The prediction is found in a technical report, co-authored by two astronomers who are targeting Sept. 1, 2007 as the date for the potential display.
The meteors are called "Aurigids" because they appear to fan-out from the constellation of Auriga, the Charioteer.
The U.S. Air Force Space Command, which tracks space movement over North America, said today there has not been a man-made object flying over the Edmonton and northern Alberta region since at least Tuesday.
So that rules out the possibility that a bright fireball seen over Edmonton in broad daylight was that kind of man-made object. A number of Edmontonians spotted a bright fireball low in the sky while driving northbound Wednesday shortly after 1 p.m.
