This image made by the NASA/ESA Hubble Space Telescope shows NGC 4526. One of the brightest lenticular galaxies known, it has hosted two known supernova explosions, one in 1969 and another in 1994, and is known to have a supermassive black hole at its center with a mass of 450 million Suns. NGC 4526 is part of the Virgo cluster of galaxies. A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Judy Schmidt during an initiative to invite astronomy enthusiasts to search the Hubble archive for notable images that have never been seen by the general public. The Hubble Space Telescope marks its 25th anniversary. A full decade in the making, Hubble rocketed into orbit on April 24, 1990, aboard space shuttle Discovery. (ESA/Hubble & NASA via AP)
