Collision May Have Formed the Moon in Mere Hours

Billions of years ago, a version of our Earth that looks very different than the one we live on today was hit by an object about the size of Mars, called Theia – and out of that collision the Moon was formed. How exactly that formation occurred is a scientific puzzle researchers have studied for decades, without a conclusive answer.

Most theories claim the Moon formed out of the debris of this collision, coalescing in orbit over months or years. A new simulation puts forth a different theory – the Moon may have formed immediately, in a matter of hours, when material from the Earth and Theia was launched directly into orbit after the impact.

Tsar Bomba – Unclassified Footage

Rosatom has released previously classified footage of the largest bomb to ever be detonated, Tsar Bomba.

With a yield of 50 megatons (50 million tons), equal to around 3,800 Hiroshima bombs, the weapon was set off over Novaya Zemlya on October 30, 1961

Update: I think they took it down? So, this seems to be a re-upload: https://www.youtube.com/watch?v=XJhZ3i-HXS0

Tip: YouTube’s auto-translated captions do a great job turning it into english.
