Two galaxies

Two galaxies in line of sight. Taken by the hubble space telescope. They are not colliding but are completely separate, (like the moon going in front of the sun).

Imagine how big the view of one galaxy would be from the other one? If we were on  a planet there half the sky would be dazzling and full of stars, the other half facing the dark of space. It could be amazing!

Shumaker-Levy 9

25 years ago  comet called Shumaker-Levy 9 collided with Jupiter and the world watched as 20 cometary fragments hit the giant planet.

Hubble space telescope saw the first large impact, then watched as the fragments continued to collide.

The planet was affected and material from below the cloud layers was thrown up into Jupiter’s upper atmosphere.

Scientists are looking for comets and asteroids that might hit Earth not Jupiter. We are lucky to have the outer gas giants because their gravity can stop some of them getting through to us!
