We have come to expect the unexpected: http://go.nasa.gov/1CBsaBi #Hubble25 | NASA - National Aeronautics and Space Administration

In its quarter-century in orbit, the Hubble Space Telescope has transformed the way we understand the Universe, helped us find our place among the stars, and paved the way to incredible advancements in science and technology. The Hubble story is a human story. Hubble overcame much adversity early on in its mission and demonstrated the great heights NASA is capable of achieving against all odds. Much of that is thanks to the “Hubble Heroes”, including scientists, engineers, and the brave astronau

We have Edwin Hubble to thank for the discovery of multiple galaxies. 🌌 The Andromeda Galaxy was observed by the astronomer Edwin Hubble in 1923 when he was looking through the Hooker telescope on Mt. Wilson in California. He saw a Cephid Variable which is a type of variable star. These stars can help astronomers measure distance by brightness. Through charting these stars, Hubble discovered that Cepheid variable stars in Andromeda were much farther away than those in the Milky Way. Hubble firs
