Meteorite that killed dinosaurs dyed tomato red


Scientists from the Wageningen University in the Netherlands, say the meteorite 10 kilometers in diameter that hit the earth causing the extinction of the dinosaurs and 70% of living species on the planet , was also responsible for the red color of tomatoes today.
This hypothesis was born after the May 30 publication of the tomato genome in the journal Nature. According to that study the genetic sequence of the plant was smaller than at present, but it tripled in size between 60 and 70 million years, coinciding with the collision of celestial object.

Good omens in the search for antique life on Mars


Structure in the meteorite ALH 84001.The tiny piece of carbon found in meteorites from Mars were formed by the cooling of volcanic emission, were not left there by ancient space germs. This is good news and bad news for astrobiologists.
The discovery in 1996 of carbonate structures in the meteorite ALH 84001, which traveled from Mars to Earth 13,000 years ago, was hailed at the time as evidence that extraterrestrial microbes have ever lived on the Red Planet. However, further studies of both the carbonate structures as tiny bits of macromolecular carbon (MMC) in the meteorite cast doubt on those claims.

Earth Meteorite flies only 14 000 kilometers higher than the Earth's outside


Recently, a newly discovered meteorite, 2012 KT42, flew past Earth at only 14,000 miles above the surface of our planet, so flying within the belt of geosynchronous satellites.
According to the orbit of this asteroid, fortunately there was no danger of collision, despite its proximity to Earth.
Moreover, in any case, due to its small size would probably have disintegrated upon entering our atmosphere.
