Today is the 20 year anniversary of the Hubble telescope being launched into outer space.
On April 24, 1990, according to CNN.com, the cutting edge telescope began taking photos of the far reaches of the Universe. Edwin Hubble, the famous astronomer, is its namesake.
CNN.com reports, "Shortly after its launch, the Hubble snapped a photo of NGC 4261, an elliptical galaxy in the Virgo Cluster. Although the telescope had a flawed mirror at the time, astronomers nevertheless were able to detect a super massive black hole at least half a billion times larger than the sun at the center of this galaxy."

In 1995, for instance, Hubble focused on a small spot in the sky for ten days straight, Time.com reports. This revealed an unbelievable 10,000 galaxies at least which are billions light years away. It is apparently the deepest visible light image ever made.
