Starry-eyed Hubble celebrates 20 years of awe and discovery
The most prolific space observatory will zoom past its 20-year milestone this weekend. On 24 April 1990, the Space Shuttle and its crew released the NASA/ESA Hubble Space Telescope into Earth orbit. What followed is one of the most remarkable sagas of the space age.
Hubbles unprecedented capabilities have made it one of the most powerful science instruments ever conceived, and certainly the one most embraced by the public. Hubbles discoveries have revolutionised nearly all areas of astronomy, from planetary science to cosmology. And its pictures are unmistakably out of this world.
At times, Hubbles starry odyssey has played out like a space soap opera: with broken equipment, a bleary-eyed primary mirror and even a Space Shuttle rescue/repair mission cancellation. But the ingenuity and dedication of Hubble scientists, engineers and NASA and ESA astronauts have allowed the observatory to rebound time and time again. Its crisp vision continues to challenge scientists with exciting new surprises and to enthral the public with ever-more evocative colour images.
NASA, ESA and the Space Telescope Science Institute (STScI) are celebrating Hubbles journey of exploration with a stunning new picture. Another exciting part of the anniversary will be the launch of the revamped European website for Hubble, spacetelescope.org. ESA will also be sponsoring the Hubble Pop Culture Contest that calls for fans to search for examples of the observatorys presence in everyday life.
To date, Hubble has looked at over 30 000 celestial targets and amassed over half a million pictures in its archive. The last heroic servicing mission by astronauts to Hubble in May 2009 made the telescope 100 times more powerful than when it was launched.
In addition to its irreplaceable scientific importance, Hubble brings cosmic wonders into millions of homes and schools every day. For the past 20 years the public have become co-explorers with this wondrous observatory.

► Eclipse over the Temple of Poseidon
The Moon moved to partly block the Sun for a few minutes last week as a partial solar eclipse became momentarily visible across part of planet Earth. In the above single exposure image, meticulous planning enabled careful photographers to capture the partially eclipsed Sun well posed just above the ancient ruins of the Temple of Poseidon in Sounio, Greece.

► Dust Sculptures in the Rosette Nebula
Noted for the common beauty of its overall shape, parts of the Rosette Nebula, also known as NGC 2237, show beauty even when viewed up close. Visible above are globules of dark dust and gas that are slowly being eroded away by the energetic light and winds by nearby massive stars. Left alone long enough, the molecular-cloud globules would likely form stars and planets. The Rosette Nebula spans about 50 light-years across and lies about 4,500 light-years away.

► Watch Jupiter Rotate
What would it be like to coast by Jupiter and watch it rotate? This was just the experience of the New Horizons spacecraft as it approached and flew by Jupiter. Visible above in the extensive atmosphere of the Solar Systems largest planet are bands and belts of light and dark clouds, as well as giant rotating storm systems seen as ovals. The robotic New Horizons spacecraft continues to speed toward the outer Solar System and has recently passed the halfway point between Earth and Pluto.

► NGC 6992: Filaments of the Veil Nebula
Wisps like this are all that remain visible of a Milky Way star. About 7,500 years ago that star exploded in a supernova leaving the Veil Nebula, also known as the Cygnus Loop. At the time, the expanding cloud was likely as bright as a crescent Moon, remaining visible for weeks to people living at the dawn of recorded history. Today, the resulting supernova remnant has faded.

► Dark Sand Cascades on Mars
They might look like trees on Mars, but theyre not. Groups of dark brown streaks have been photographed by the Mars Reconnaissance Orbiter on melting pinkish sand dunes covered with light frost. The image was taken near the North Pole of Mars. At that time, dark sand on the interior of Martian sand dunes became more and more visible as the spring Sun melted the lighter carbon dioxide ice. When occurring near the top of a dune, dark sand may cascade down the dune leaving dark surface streaks streaks that might appear at first to be trees standing in front of the lighter regions, but cast no shadows.

► Eclipses in the Shade
Eclipses are everywhere in this shady scene. The picture was taken on the Indian Ocean atoll island of Ellaidhoo, Maldives, in January 2010, during the longest annular solar eclipse for the next 1,000 years. Tall palm trees provided the shade. Their many crossed leaves created gaps that acted like pinhole cameras, scattering recognizable eclipse images across the white sands of a tropical garden near the beach. From this idyllic location near the centerline of the Moons shadow track, the ring of fire or annular phase of the eclipse lasted about 10 minutes and 55 seconds.

► Dust and the NGC 7771 Group
Some 200 million light-years distant toward the constellation Pegasus, NGC 7771 is the large, edge-on spiral near center, about 75,000 light-years across, with two smaller galaxies just below it. Large spiral NGC 7769 is seen face-on to the right. Galaxies of the NGC 7771 group are interacting, making repeated close passages that will ultimately result in galaxy-galaxy mergers on a cosmic timescale.

► Millennium Annular Solar Eclipse
The Moons shadow raced across planet Earth on January 15. Observers within the central shadow track were able to witness an annular solar eclipse as the Moons apparent size was too small to completely cover the Sun. A visually dramatic ring of fire, the annular phase lasted up to 11 minutes and 8 seconds depending on location, the longest annular solar eclipse for the next 1,000 years.

► A Sun Halo Over Cambodia
Have you ever seen a halo around the Sun? This fairly common sight occurs when high thin clouds containing millions of tiny ice crystals cover much of the sky. Each ice crystal acts like a miniature lens. Because most of the crystals have a similar elongated hexagonal shape, light entering one crystal face and exiting through the opposing face refracts 22 degrees, which corresponds to ... http://antwrp.gsfc.nasa.gov/apod/ap100208.html
► Night Launch of the Space Shuttle Endeavour
Sometimes, the space shuttle launches at night. Pictured above, the space shuttle Endeavour lifted off in yesterdays early morning hours from Launch Pad 39A in Kennedy Space Center, Florida, USA, bound for the International Space Station (ISS). A night launch, useful for reaching the space station easily during some times of the year, frequently creates ... http://antwrp.gsfc.nasa.gov/apod/ap100209.html
► M51 Hubble Remix
The 51st entry in Charles Messiers famous catalog is perhaps the original spiral nebula - a large galaxy with a well defined spiral structure also cataloged as NGC 5194. Over 60,000 light-years across, M51s spiral arms and dust lanes clearly sweep in front of its companion galaxy (top), NGC 5195. Image data from the Hubbles Advanced Camera for Surveys has been reprocessed to ... http://antwrp.gsfc.nasa.gov/apod/ap091226.html
► Teide Sky Trails
The snow capped Teide volcano is reflected in a pool of water in this nearly symmetric night sky view from the Canary Island Tenerife. Bright north star Polaris stands above the peak in an exposure that also captures the brilliant trail of a polar orbiting Iridium satellite. Of course, with the camera fixed to a tripod, the stars themselves produce concentric trails in long exposures, a reflection of the Earths rotation around its axis ... http://antwrp.gsfc.nasa.gov/apod/ap100212.html
► Star Cluster M34
This pretty, open cluster of stars, M34, is about the size of the Full Moon on the sky. Easy to appreciate in small telescopes, it lies some 1,800 light-years away in the constellation Perseus. At that distance, M34 physically spans about 15 light-years. Formed at the same time from the same cloud of dust and gas, all the stars of M34 are about 200 million years young. But like any open star cluster ... http://antwrp.gsfc.nasa.gov/apod/ap100211.html
► A Force from Empty Space: The Casimir Effect
This tiny ball provides evidence that the universe will expand forever. Measuring slightly over one tenth of a millimeter, the ball moves toward a smooth plate in response to energy fluctuations in the vacuum of empty space. The attraction is known as the Casimir Effect, named for its discoverer, who, 50 years ago, was trying to understand why fluids like mayonnaise move so slowly ... http://antwrp.gsfc.nasa.gov/apod/ap061217.html
► Field of Rosette
What surrounds the florid Rosette nebula? To better picture this area of the sky, the famous flowery emission nebula on the far right has been captured recently in a deep and dramatic wide field image that features several other sky highlights. Designated NGC 2237, the center of the Rosette nebula is populated by the bright blue stars of open cluster NGC 2244, whose winds and energetic light are ... http://antwrp.gsfc.nasa.gov/apod/ap100214.html
► A Graceful Arc
The graceful arc of the Milky Way begins and ends at two mountain peaks in this solemn night sky panorama. The view was created from a 24 frame mosaic, with exposures tracking Earth and sky separately. In the final composition, northern Californias Mount Lassen was positioned at the left and Mount Shasta at the far right ... http://antwrp.gsfc.nasa.gov/apod/ap091225.html
► Sakurajima Volcano with Lightning
Why does a volcanic eruption sometimes create lightning? The Sakurajima volcano in southern Japan was caught erupting early last month. Magma bubbles so hot they glow shoot away as liquid rock bursts through the Earths surface from below. http://antwrp.gsfc.nasa.gov/apod/ap100210.html
► Waterway to Orbit
The 32nd shuttle mission to the International Space Station, STS-130, left planet Earth on February 8. Its early morning launch to orbit from Kennedy Space Centers pad 39A followed the long, graceful, eastward arc seen in this two minute time exposure ... http://antwrp.gsfc.nasa.gov/apod/ap100213.html
