1908's Tunguska Event Makes Chelyabinsk Meteor Look Like a Pebble.

The meteor that crashed to Earth last week was a sight to behold.

55 feet long and 10,000 tons heavy, the Chelyabinsk meteor is the biggest object to hit our planet in over 100 years. But the site of the impact was curiously close to the last big one, the event now referred to as the "Tunguska event." 

At 7:14 PM on June 30th, 1908, there was a massive explosion that rocked the earth's surface over Siberia. While we can't definitively prove that it was a meteor, whatever it was, that sucker dwarfed last week's meteor by a factor of six.  The explosion was 1000 times more powerful than the nuclear bomb dropped on Hiroshima. 

Only one death was reported, but the damage was dramatic: the event flattened a five mile swath of Siberian forest.

Interestingly, there's still a lot of dissent about what actually happened at Tunguska. The meteor theory is still the prevailing wisdom, yet the lack of a discernible crater has spawned several competing theories. Could the mass have been a chunk of a comet?  Or some kind of freakish nuclear fusion reaction? Could it have been a release of gas from beneath the Earth's crust?  Some have even speculated that Tunguska was the result of a freakin' black hole, or an alien spacecraft!

Shortly after last week's meteor strike, a deluge of cell phone video, shot from hundreds of angles, tore through the Internet. And, of course, conspiracy theories popped up everywhere. Was it a weapon? Was it shot down? Probably not.

As citizen video proliferates, so do crackpot theories. That's the flip side to an open Internet.  Since we can't even agree about what happened last week in front of thousands of cameras, it's safe to assume that there will always be doubt over exactly what happened in the skies on that Siberian summer day over 100 years ago.

Para começar, o correto é aerólito e não aerolito, trata-se de um substantivo proparoxítono e não paroxítono, como divulgado pelo cientista interpretado pelo inesquecível Ramon Valdez e um episódio do Chapolin Colorado. Aerólito é um tipo de meteorito que é composto basicamente de minerais silicatados, sendo assim ele é rochoso, e não metálico (siderito) ou metálico-rochoso (siderólito).

Today I wrote a blog post trying to summarise the recent happenings over the Russian meteorite. It didn't take me long to write after surfing through my twitter links I had saved in Evernote, however by 4 or 5ish this afternoon, the blog post was already a little bit out of date so I had to add a little bit right at the end. This was my worry from the start the the news story would be so evolving and changing so fast that it would get out of date quickly. It's times like this when live updates are useful. Orginally from the sports world, it allows a constant update of stories. However it also brings problems in fact checking. Even with this blog post 3 days after the event, facts were changing. NASA had revised the mass and hence energy of the meteorite and sources that I linked too had differing amount depending on when they published their stories. Edit: 21/02/13 11:28 My blog piece got quoted as a source for an io9 piece
