The Hubble Space Telescope was launched April 24, 1990, from the space shuttle Discovery.

NASA called Hubble the "most significant advance in astronomy since Galileo's telescope." Hubble has given us better views of our solar system and taken us hundreds of light years away to the edge of the universe.

Hubble captured an image of three galaxies in a tug-of-war millions of light-years from Earth. This system is known as Arp 195 and was included in the <a href="index.php?page=&url=https%3A%2F%2Fned.ipac.caltech.edu%2Flevel5%2FArp%2Fpaper.pdf" target="_blank" target="_blank">Atlas of Peculiar Galaxies</a>.

Hubble took this image of the rare blue variable star AG Carinae, located 20,000 light-years away from Earth in the Milky Way galaxy, to celebrate the 31st anniversary of its launch. The star has experienced several explosions that created its distinctive halo.

The Orion Nebula is 1,500 light-years from Earth and is located in<strong> </strong>Orion's Belt in the constellation Orion. It's one of the brightest nebulae -- and on a clear, dark night it's visible to the naked eye. The nebula is Earth's nearest star-forming region.

Hubble has given us many images of our neighbor Mars. This image was taken in 2003 when Mars made its closest approach in nearly 60,000 years. On August 27, 2003, the two worlds were only 34.6 million miles apart from center to center. By contrast, Mars can be about 249 million miles away from Earth.

Hubble discovered four of Pluto's five moons. In 2005: Nix and Hydra were found. Hubble discovered Kerberos in 2011 and Styx in 2012. The new discoveries joined Pluto's large moon, Charon, which was discovered in 1978. Styx was found by scientists using Hubble to search for potential hazards for the New Horizons spacecraft which flew by Pluto in July 2015. Pluto is about 2.9 billion miles from Earth.

The Cat's Eye Nebula is a bunch of glowing gases kicked out into space by a dying star. This Hubble Space Telescope image shows details of structures including jets of high-speed gas and unusual knots of gas. This color picture is a composite of three images taken at different wavelengths. The nebula is estimated to be 1,000 years old. It's about 3,000 light years from Earth in the constellation Draco.

The Bug, or Butterfly Nebula looks like a butterfly with its wings stretching across the galaxy. It's actually a cloud of roiling gas shed by a dying star. Scientists say the gas is more than 36,000 degrees Fahrenheit and is expanding into space at more than 600,000 miles an hour. This image was taken with Hubble's Wide Field Camera 3, a camera installed on Hubble during its May 2009 upgrade by shuttle astronauts. The nebula is about 3,800 light years away in the constellation Scorpius.

Astronomers combined several Hubble images taken in 2014 to create an upgraded view of the Hubble's iconic 1995 "Pillars of Creation" image. The new image shows a wider view of the pillars, which stretch about 5 light-years high. The pillars are part of a small region of the Eagle Nebula, which is about 6,500 light years from Earth.

This huge nebula is 7,500 light years from Earth in the constellation Carina. It's one of the largest and brightest nebulas and is a nursery for new stars. It also has several stars estimated to be at least 50 to 100 times the mass of our Sun, including Eta Carinae, one of the brightest stars known and one of the most massive stars in the Milky Way Galaxy.

One of the closest neighbors to our own Milky Way, the Andromeda Galaxy, can be seen with the naked eye if you know where to look on a clear, dark night. In 2012, scientists using data from Hubble predicted Andromeda would collide with the Milky Way in about four billion years. Andromeda is 2.5 million light years from Earth.

In 2004, astronomers unveiled the deepest portrait of the visible universe ever taken to date. Called the Hubble Ultra-Deep Field, the million-second-long exposure shows the first galaxies to emerge shortly after the Big Bang. The image shows an estimated 10,000 galaxies. In 2012, astronomers assembled an upgraded image called the Hubble eXtreme Deep Field. It combined 10 years of Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra-Deep Field. The new image contains about 5,500 galaxies.

The Cone Nebula is a turbulent star-forming pillar of gas and dust. It's 7 light-years long, but this image taken by Hubble in 2002 shows the top 2.5 light-years (which equals 23 million round trips to the moon). Ultraviolet radiation causes the hydrogen gas to emit an eerie red glow.
