If it were not scientifically verified, it would be a great storyline for a sci-fi flick, but NASA says alien microbes are hitching rides on meteorites. Some experts are stating that debris from outer space will only be increasing in frequency as they impact Earth in the coming year.
A meteorite's size can range from small to extremely large. When a meteoroid enters the atmosphere, frictional, pressure, and chemical interactions with the atmospheric gases cause the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting/falling star. They can range from extraterrestrial bodies that collide with Earth or an exceptionally bright, fireball-like meteor regardless of whether it ultimately impacts the surface.
NASA has launched a new website to share details of meteor explosion events as recorded by U.S. military sensors on secretive spacecraft, kicking off the project with new details of this past February's fireball over Chelyabinsk, Russia.
The new "Fireball and Bolide Reports" website, overseen by NASA's Near-Earth Object Program, debuted Friday (March 1) with its first entry: a table with a chronological data summary of the Russian meteor explosion
of Feb. 15 gleaned from U.S. Government sensor data. Scientists are calling the event a "superbolide," taken from the term "bolide" typically used for fireballs created by meteors.
Part of the worldwide interest in meteors hitting Earth stems from what is now verifiable evidence that alien lifeforms are coming along for the ride.
In 2010, Duane P. Snyder announced the discovery of the first and only known Ice Meteorite containing Extraterrestrial Life-forms. The Ice Meteorite's particle analysis, its gas analysis, and likely origin including photos of the life-forms found in the melt-water of the meteorite where also exhibited. Dr. Albert Schnieders of Tascon USA Inc, commented that they basically found nearly all elements up to 90u in the sample spherical particles tested.
