Canadians living north and northeast of Toronto are being asked to help search for meteorite fragments from a fireball last month. In a release, the Royal Ontario Museum in Toronto and the University of Western Ontario in London said analysis of a network of sky camera footage shows a slow-moving fireball swept eastward on March 15 at 8:37 p.m. near the small city of Newmarket. The museum is scheduling a public workshop in Newmarket on what to look for in the fragments, which are likely to be...

A massive fireball that shot over the skies of Northern Ireland on Sunday may finally be explained due to some security cameras that may have captured the event, BBC News reported. People living as far apart as Donegal and Cork reported seeing a shooting star blazing across the skies around 1230 BST. "We're fairly certain it was a rock from space which could have landed somewhere in Ireland," said David Moore chairman of Astronomy Ireland. Astronomers and sky watchers are hoping to hear from...

Just before dawn on Oct. 7, 2008, an SUV-sized asteroid entered Earth's atmosphere and exploded harmlessly over the Nubian Desert of northern Sudan. Scientists expected the asteroid, called 2008 TC3, had blown to dust in the resulting high-altitude fireball. What happened next excited the scientific community. Peter Jenniskens, a meteor astronomer with the SETI Institute in Mountain View, Calif., who works at NASA's Ames Research Center in Moffett Field, Calif., joined Muawia Shaddad of the...

Two rare meteorites found in Antarctica two years ago are from a previously unknown, ancient asteroid with an outer layer or crust similar in composition to the crust of Earth's continents, reports a research team primarily composed of geochemists from the University of Maryland.Published in the January 8 issue of the journal Nature, this is the first ever finding of material from an asteroid with a crust like Earth's. The discovery also represents the oldest example of rock with this...

Researchers have reported discovering small fragments of meteorites that are related to others found in China, the US and Australia. The small, sand-like fragments may explain a connection between earthquakes and tsunamis and a massive meteorite shower that occurred some 470 million years ago, according to a team of researchers from the University of Aberdeen. The find was made near Durness, which led Professor John Parnell from the School of Geosciences at the University of Aberdeen and his...

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...

London's Natural History Museum has purchased a rare type of meteorite that could hold clues to the birth of our Solar System. The meteorite was obtained from a private collection. The Ivuna meteorite has the same chemical make-up from which the Solar System formed 4.5 billion years ago. The meteorite landed in Tanzania as one 705g stone in 1938 and has since been split into two samples. Parts of the UK sample will be removed for study. Most Ivuna samples are held in private collections, or...

Higher than expected levels of sodium found in a 4.6 billion-year-old meteorite suggest that the dust clouds from which the building blocks of the Earth and neighboring planets formed were much denser than previously supposed. The study, by scientists from the Carnegie Institution, American Museum of Natural History, and U.S. Geological Survey, is published in the June 20 issue of Science. Conel Alexander and Fred Ciesla of the Carnegie Institution's Department of Terrestrial Magnetism, with...

COLLEGE PARK, Md. -- Using visible and infrared data collected from telescopes on Hawaii's Mauna Kea, a team of scientists, led by the University of Maryland's Jessica Sunshine, have identified three asteroids that appear to be among our Solar System's oldest objects. Evidence indicates that these ancient asteroids are relatively unchanged since they formed some 4.55 billion years ago and are older than the oldest meteorites ever found on Earth, say Maryland's Sunshine and colleagues from the...

Amino acids that are the building blocks of life have been found in their highest ever concentration in two ancient meteorites which crashed to Earth millions of years ago, scientists claim today.Scientists believe their research, published online in the journal Meteoritics and Planetary Science, provides fresh insights into the origins of life on Earth.Amino acids form the basis of proteins and enzymes, which are the building blocks of all biological life. They have been found in ancient...

Meteorite -- A meteorite is a relatively small extraterrestrial material body that reaches the Earth's surface. While in space these bodies are called meteoroids. Upon entering the atmosphere air drag and friction will cause the body to heat up, emitting light, thus forming a meteor, fireball, or shooting star. Most meteors disintegrate in the air, making impact events (Earth impacts) on the surface of Earth uncommon. About 500 baseball sized rocks a year reach the surface. Large...
