That meteorite which blew-up over California last April is one of the…

This past April, a 100,000 pound (45,360 kg) meteorite exploded above the skies of Sutter's Mill, California. Streaking in at a speed of 64,000 miles per hour (103,000 km/hr or 28.6 km/s) — about twice the speed of typical meteorite falls — it hit with the energy of a quarter of a Hiroshima bomb, making it the… » 12/21/12 8:40am 12/21/12 8:40am

This Sun-like star is surrounded by sugar

A team of European and American astronomers have found signs of a simple sugar molecule, glycolaldehyde, in a gas cloud surrounding a young sun-like star. Located 400 light-years away, it's the first time that sugar has been located around such a celestial object — and this indicates that the early building blocks of… » 8/29/12 4:00pm 8/29/12 4:00pm

Chemist Discovers the Origins of Life in a Cardboard Box

In 1953, chemists Stanley Miller and Harold Urey created life. They filled flasks with water and gases from Earth’s primordial atmosphere and, with a jolt of electricity, created amino acids, the building blocks of all life on this planet. Last year, a former student of Miller’s discovered the remnants of the… » 10/17/08 8:40am 10/17/08 8:40am

Proto-DNA from Meteorites Kick-Started Life on Earth

How life got started on Earth is still a big problem for scientists. The story goes something like this: "Well, there was this primordial soup of amino acids and stuff, then maybe there was some lightning, or something, and then ::mumble, mumble:: and then we had life." Awkward! But that awkwardness may be over:… » 6/16/08 10:00am 6/16/08 10:00am
