M65 and M66

In close proximity bright spiral galaxies M65 and M66 are highlighted in this attractive cosmic image. The pair is about 35 million light years and measured, each, about 100,000 light-years .

Both display prominent dust lanes that spiral arms sweep. M66 has a particularly striking contrast of red and blue colors, the red light shows the regions of hydrogen gas to form stars and star clusters.

M65 and M66 are two of the three galaxies known as the Leo Triplet , where the gravitational effect of the tide including how matter warps, evidence of how close they are.

M66 has been home to four brilliant supernovae since 1973 .

The Largest impact craters that have beaten the Earth

Imagine staring at the sky, which gradually gets closer, more and more closely. That point doubling in size every second, to darken the sky. His entry into the atmosphere is accompanied by light and heat, the giant rock wrapped in a meteor full of death that goes directly to you. 

It sounds like the introduction of a catastrophic film, however not very far from reality as these impacts ended the lives of potential witnesses to the event in his time, leaving only the record of their impact on Earth's surface. Today we will show the largest impact craters that have impacted the Earth. In ascending order according to their size, see:
