This is a Hubble Space Telescope composite image of a supernova explosion designated SN 2014J in the galaxy M82. At a distance of approximately 11.5 million light-years from Earth it is the closest supernova of its type discovered in the past few decades. | NASA, ESA, A.

Hubble at 25: Space Telescope's Top Science Discoveries

Hubble’s scientific bounty has benefited a wide range of astronomical and astrophysical fields, including the study of planets, moons and small icy bodies in the outer solar system and the cosmological history of the universe. Here’s a look at a few of Hubble’s greatest hits.

This image, taken with the Advanced Camera for Surveys aboard NASA's Hubble Space Telescope, shows the newly discovered planet, Fomalhaut b, orbiting its parent star, Fomalhaut. | NASA, ESA, P.

This illustration depicts the extrasolar planet HD 189733b with its parent star peeking above its top edge. Astronomers used the Hubble Space Telescope to detect methane and water vapor in the Jupiter-size planet's atmosphere. | NASA, ESA, and G. Bacon (STScI)
A black hole roughly 100 million times as big as the sun lurks in the heart of our neighbor spiral galaxy, M31, also known as Andromeda. The so-called "event horizon" -- the closest region around the black hole where light can still escape, is too small to be seen, but it lies near the middle of a compact cluster of blue stars at the center of the image. | NASA, ESA, and T. Lauer (National Optical Astronomy Observatory)
A new dark spot on Jupiter is imaged by Hubble on July 23, 2009. | NASA, ESA, H. Hammel (Space Science Institute, Boulder, Colo.), and the Jupiter Impact Team
Within a massive cluster of galaxies known as MACS J1149.6+2223 and located more than 5 billion light-years away, lies a lensed view of a galaxy 9.3 billion light-years away. | NASA, ESA, and S.
