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...

Brown University professor Peter Schultz's study of the Peruvian meteorite has yielded some interesting conclusions that could upend the conventional wisdom about the size and type of meteorites that can strike Earth.It made news around the world: On Sept. 15, 2007, an object hurtled through the sky and crashed into the Peruvian countryside. Scientists dispatched to the site near the village of Carancas found a gaping hole in the ground. Peter Schultz, professor of geological sciences at...

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...

Cool place, hot bodies Picture a cool place, teeming with a multitude of hot bodies twirling about in rapidly changing formations of singles and couples, partners and groups, constantly dissolving and reforming. If you were thinking of the dance floor in a modern nightclub, think again. It's a description of the shells around dying stars, the place where newly formed elements make compounds and life takes off, said Katharina Lodders, Ph.D., research associate professor of earth and...

NASA researchers at Johnson Space Center, Houston have found organic materials that formed in the most distant reaches of the early Solar System preserved in a unique meteorite. The study was performed on the Tagish Lake carbonaceous chondrite, a rare type of meteorite that is rich in organic (carbon-bearing) compounds. Organic matter in meteorites is a subject of intense interest because this material formed at the dawn of the Solar System and may have seeded the early Earth with the...

By ROXANA HEGEMAN, Associated Press Writer GREENSBURG, Kan. - Scientists located a rare meteorite in a Kansas wheat field thanks to new ground penetrating radar technology that some day might be used on Mars. The dig Monday was likely the most documented excavation yet of a meteorite find, with researchers painstakingly using brushes and hand tools in order to preserve evidence of the impact trail and to date the event of the meteorite strike. Soil samples were also bagged and tagged, and...

PROVIDENCE, R.I. -- Asteroids and meteorites are supposed to be made of the same stuff "“ at least that's what earth science teachers have been telling their students for decades. But until re-cently, the data didn't quite fit the story. When researchers compared the near-infrared reflec-tance of asteroids (as measured from Earth) and meteorites (collected on Earth) they found enough differences to raise doubts about whether the asteroids really could be the source of Earth's...

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...

tesla
  • 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.
