Hubble Deep Field
In April 1990 Hubble's Telescope was sent into space. It took countless amount of photos, one of them showing gas clusters called "Pillars of Creation" (picture 1.) - One of the most recognizable picture of the universe. What most of people don't know is that this telescope took probably the most important photo of universe which contributed to many theories and discoveries.
What you see on picture 2. is called Hubble Deep Field and it came out from rather an unusual event. Usually when astronomers want to study certain obejcts they point the telescope right onto that object but in 1995 Robert Williams (director of the telescope at that time) decided to point the telescope at nothing in particular. They wanted to observe distant galaxies so they had to point the telescope the way that no bright objects from our galaxy obstruct the view. The field of view was smaller than a pinhead. The observations began on december 18 1995 and over the next 10 days the telescope took 342 images. What's amazing about this picture is that you can see very young galaxies that were created not so long ago and in the back you can see galaxies that have been created right after big bang. The differnce between them is almost 12 billion years which is truly insane. That's like having the enitre history of the universe in one picture.

It's incredible to see that so much is going on in these pictures and yet, when you look at the sky, it seems so peaceful and motionless.
