5. Hubble space telescope:
25 years photographing the galaxies far, far away

6. This month Nasa/ESA's Hubble space telescope is
celebrating 25 years exploring the sky above us,
enabling the humble habitants of planet Earth to
understand at least some of the many secrets of the
universe. Here's our selection of Hubble's most
impressive images over the years.

7. The Hubble Space Telescope was launched April
24, 1990, from Kennedy Space Center, Florida,
aboard the space shuttle Discovery.
NASA calls Hubble the "most significant
advance in astronomy since Galileo's
telescope." Hubble has given us new, better
views of our solar system and has taken us
hundreds of light years away to the edge of the
universe.

12. 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.

13. Hubble snapped this image in 2007 of Ganymede appearing to peek out from beneath Jupiter. Ganymede is the largest moon in our solar system and it's even
bigger than Mercury.

14. Hubble captured this image of Saturn in 2004, a view so sharp that some of the planet's smaller rings are visible.

15. Hubble tracked clouds on Uranus in this image taken in 1997. The image is a composite of three near-infrared images. The planet's rings are prominent in the near
infrared. Eight of Uranus' 27 moons can be seen in both images. Uranus is about 1.75 billion miles from Earth.

16. Hubble captured this image of the distant blue-green world Neptune in 2005. Fourteen different colored filters were used to help scientists learn more about
Neptune's atmosphere. Neptune is about 2.8 billion miles from Earth.

17. 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 will fly by Pluto in July 2015. Pluto is about 2.9 billion miles from Earth.

18. The Orion Nebula is 1,500 light years from Earth located in 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.

19. The iconic Horsehead Nebula is a favorite target for astronomers. Look carefully and you'll see what looks like the head of horse rising into the stars. This Hubble
image captures the nebula in infrared wavelengths. The nebula is 1,600 light years from Earth.

20. 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.

21. 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.

22. 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.

23. 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.

24. 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.

25. The Cigar Galaxy is 12 million light years away. It gets its name from its shape: From Earth it looks like an elongated elliptical disc.

26. It's called one of the most photogenic galaxies: The Sombrero Galaxy looks like the giant broad rim of a Mexican hat sitting out among the stars. It can be spotted
using a small telescope. It's about 28 million light years from Earth.

27. This group of galaxies is about 290 million light years from Earth. It's named for its discoverer, French astronomer Edouard Stephan, who first spotted it in 1877.

28. Hubble captured this image of a group of interacting galaxies called Arp 273. The bigger galaxy has a center disk that is distorted into a rose-like shape by the pull
from its partner below.

29. 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.

photo released by NASA on December 4, 2011. Light from the flash is reflected by successively more distant rings in the ambient interstellar dust that already
surrounded the star. V838 Mon lies about 20,000 light years away toward the constellation of Monoceros the unicorn. It became the brightest star in the Milky Way
Galaxy in January 2002 when its outer surface greatly expanded suddenly.Picture: REUTERS/ NASA, ESA, H. E. Bond

78. In the centre of this image, taken with the NASA/ESA Hubble Space Telescope, is the galaxy cluster SDSS J1038+4849 and it seems to be smiling. You can make out
its two orange eyes and white button nose. In the case of this happy face , the two eyes are very bright galaxies and the misleading smile lines are actually arcs
caused by an effect known as strong gravitational lensing.Galaxy clusters are the most massive structures in the Universe and exert such a powerful gravitational
pull that they warp the spacetime around them and act as cosmic lenses which can magnify, distort and bend the light behind them. This phenomenon, crucial to
many of Hubble s discoveries, can be explained by Einstein s theory of general relativity. In this special case of gravitational lensing, a ring known as an Einstein
Ring is produced from this bending of light, a consequence of the exact and symmetrical alignment of the source, lens and observer and resulting in the ring-like
structure we see here. Hubble has provided astronomers with the tools to probe these massive galaxies and model their lensing effects, allowing us to peer further
into the early Universe than ever before.Picture: NASA/ESA/Hubble
