When we look into space, we are looking into the past of planets and stars.
If a person were living in one of these stars and observing Earth, they would see the past, including dinosaurs and ancient civilizations like the pharaohs.
In 1996, the Hubble Telescope captured an image of 3,000 previously unseen galaxies, while in 2004 it captured an image of 10,000 galaxies in just one day.
The Hubble Telescope has provided us with detailed views of star formation in regions known as star nurseries.
