• Most of the stars you see in the night sky are bigger and brighter than the sun. The dimmest of the 50 most prominent stars in our sky is Alpha Centauri, which is more than 1.5 times brighter than the sun. • The farthest object spotted by the Hubble Space Telescope is a tiny red smudge about 13.4 billion light years away, near the dawn of the birth of the universe. • The object generally regarded as the most distant the average backyard astronomer can see is the quasar 3C273, about 2.5 billion light years away. • There are 200 – 400 billion stars in our Milky Way galaxy. The Hubble reveals an estimated 100 billion galaxies in the universe, but this number is likely to increase to about 200 billion as space telescope technology improves.
