Did a Comet Really Chill and Kill Clovis Culture?

A comet crashing into the Earth some 13,000 years ago was thought to have spelled doom to a group of early North American people, and possibly the extinction of ice age beasts in the region.

But the space rock was wrongly accused, according to a group of 16 scientists in fields ranging from archaeology to crystallography to physics, who have offered counterevidence to the existence of such a collision.

Incoming! Tunguska-class bolide to miss Earth by just 22,500km on 15 February 2013

An asteroid the size of a city block is due to come whizzing past Earth closer than any other of its size in recorded history in February next year, according to astronomers.

The asteroid, referred to as 2012 DA14, has a diameter of approximately 45m and an estimated mass of 130,000 tonnes. It was discovered at the start of 2012 and is set to travel between the Earth and our geostationary communication satellites on 15 February 2013. At a distance of just 22,500km this will be the closest asteroid 'fly by' in recorded history.

S-au împlinit 104 ani de la explozia misterioasă de la Tunguska

Pe 30 iunie s-au împlinit 104 ani de la misterioasa explozie din zona forestieră Tunguska, în mijlocul Siberiei. Aceasta a avut puterea a 15 megatone de TNT, aproximativ de 1000 de ori mai puternică decât bomba atomică de la Hiroshima.

Explozia din pădure a fost atât de puternică încât a fost simțită și auzită la mai bine de 1.500 de kilmetri depărtare, relatează Business Insider.
Localnicii atribuie fenomenul unor cauze supranaturale, unui zeu ce pedepsește răutatea oamenilor. Oamenii de știință, însă, consideră că a fost vorba de un meteorit.
