...then, black holes exist. Wow!!!!!
This picture was taken by a group of telescopes strategically located around the Earth. What that means is that a telescope the size of the Earth took this image. Incredible! Basically, a black hole is a gigantic sun (6.5 billion suns) which collapsed onto itself (due to gravity) into something much smaller. The gravity is so dense that nothing can escape...not even light. That's why black holes are, well, black. The center of each galaxy has at least one black hole. They are so small and so far away that it was thought to be impossible to take an image of one. This is an interesting article from the N.Y. Times explaining this incredible image in more detail.
When I see an image like this I'm reminded about how trivial our every day troubles are. This is an amazing example of humans working together to achieve an impossible goal. Fantastic!!
