Astronomers Find Oldest Known Asteroids

Researchers from the University of Maryland have recently discovered three asteroids that appear to be roughly 4.55 billion years old, dating back to the formation of the Solar System. The scientists say that the asteroids have survived relatively unchanged since that time, and make good candidates for future space missions. "'The fall of the Allende meteorite in 1969 initiated a revolution in the study of the early Solar System,' said Tim McCoy, curator of the national meteorite collection at the Smithsonian's National Museum of Natural History. 'I find it amazing that it took us nearly 40 years to collect spectra of these [CAI-rich] objects and that those spectra would now initiate another revolution, pointing us to the asteroids that record this earliest stage in the history of our Solar System.

Maryland Led Team Finds Oldest Known Asteroids

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.

The Oldest Asteroids

Stellar Evolution Summary (Mar 25, 2008): Scientists have discovered three asteroids that appear to be among the oldest objects in the Solar System. Studying these asteroids could yield important clues about the origin and evolution of the planets.

Astronomers find grains of sand around distant stars

In a find that sheds light on how Earth-like planets may form, astronomers this week reported finding the first evidence of small, sandy particles orbiting a newborn solar system at about the same distance as the Earth orbits the sun. The report will be published online this week by the journal Nature.

Oldest known human fossil found

This undated image released by the Atapuerca Research Team (EIA)Â on March 26, 2008, shows a small piece of jawbone unearthed in a cave in Spain. The jawbone is the oldest known fossil of a human ancestor in Europe and suggests the continent was peopled much earlier than previously believed, scientists say.

Discovery Of Oldest Known Traces Of Mineralization Caused By Micro-organisms

An old controversy has finally been laid to rest. Stromatolites, cauliflower-shaped carbonate rocks that are found in abundance in geological formations, including ones that are several billion years old, show definite evidence of ancient biological activity. This has just been shown by researchers at the Institut de Physique du Globe in Paris (CNRS/Université Paris 7), thanks to detailed analysis of 2.7 billion-year-old rocks from cores drilled in Australia. Previously, the oldest known traces of mineralization caused by micro-organisms were only 350 million years old.

U.S. experts find oldest voice recording, from 1860

WASHINGTON (Reuters) - U.S. audio historians have discovered and played back a French inventor's historic 1860 recording of a folk song -- the oldest-known audio recording -- made 17 years before Thomas Edison invented the phonograph.

Ancient asteroids 'found' in solar system

Astronomers have identified three ancient asteroids which they claim are among our Solar System's oldest objects.

The Big Announcement: Chandra, VLA Find Youngest Supernova in Our Galaxy

Astronomers have found the remains of the youngest supernova, or exploded star, in the Milky Way Galaxy. The supernova occurred in 1868, but was hidden behind a thick veil of gas and dust. Using the Very Large Array (VLA) and NASA's Chandra X-Ray Observatory, which could peer through the veil, astronomers have now found "G1.9+0.3," the first example of what scientists believe are a "missing population" of young supernova remnants. This is NASA's long awaited announcement, and astronomers have been searching for over 50 years for this type of young supernova.
