On a marathon spacewalk Sunday, two astronauts overcame repeated obstacles to make the second of two historic repairs to the Hubble Space Telescope.
One bolt that had to be extracted proved so stubborn that astronaut Michael Massimino resorted to brute force to rip it out of the telescope.
His efforts paid off. Hubble's $166 million chemical analyser, dead for nearly five years, came back to life after Massimino and a colleague rewired its electronics.

Astronauts have completed the most critical repair to the Hubble Space Telescope after a long struggle.
Mission specialists Mike Good and Mike Massimino put a refurbished pair of gyroscopes into the telescope after a new set refused to go in.
Besides the gyroscopes - to orient it precisely - Hubble got fresh batteries to ensure five more years of life.

Myriad galaxies, including some of the - cosmos's remotest objects, are caught by the Hubble Space Telescope, providing astronomers with key information about the universe's early history. The newly-released image was one of the last taken before this week's repair mission to the telescope, which orbits Earth, by the space shuttle Atlantis. Repair flights were cancelled after the Columbia disaster but a public outcry forced a Nasa rethink. Engineers say this should extend Hubble's life by five years or more. After that, new robot observatories - requiring no servicing by astronauts - should be in place.

The Hubble Telescope was carried into orbit on this day, April 24th, back in 1990, which makes it 19 years old.

Tell Hubble Where To Point

Hubble's Next Discovery -- You Decide" is part of the International Year of Astronomy (IYA), the celebration of the 400th anniversary of Galileo's observations. People around the world can vote to select the next object the Hubble Space Telescope will view. Choose from a list of objects Hubble has never observed before and enter a drawing for one of 100 new Hubble pictures of the winning object. The winning image will be released between April 2 and 5, during the IYA's 100 Hours of Astronomy, a global astronomy event geared toward encouraging as many people as possible to experience the night sky. Vote by March 1 to swing Hubble toward your favourite target.

A camera developed by a University of Arizona-led team for the Hubble Space Telescope has helped produce an infrared mosaic image that is the sharpest infrared picture ever made of a large area at the center of our Milky Way.
The image shows the sweeping panorama of a new population of massive stars and new details in complex structures in the hot ionised gas swirling within 300 light-years of the Galactic center.
The new view combines the sharp imaging of the Hubble Space Telescope's Near Infrared Camera and Multi-Object Spectrometer, or NICMOS, with colour imagery from a previous Spitzer Space Telescope survey done with its Infrared Astronomy Camera.

Hubble Scores a Perfect TenNASA's Hubble Space Telescope is back in business. Just a couple of days after the orbiting observatory was brought back online, Hubble aimed its prime working camera, the Wide Field Planetary Camera 2 (WFPC2), at a particularly intriguing target, a pair of gravitationally interacting galaxies called Arp 147. The image demonstrated that the camera is working exactly as it was before going offline, thereby scoring a "perfect 10" both for performance and beauty.

The two galaxies happen to be oriented so that they appear to mark the number 10. The left-most galaxy, or the "one" in this image, is relatively undisturbed apart from a smooth ring of starlight. It appears nearly on edge to our line of sight. The right-most galaxy, resembling a zero, exhibits a clumpy, blue ring of intense star formation. The galaxy pair was photographed on October 27-28, 2008. Arp 147 lies in the constellation Cetus, and it is more than 400 million light-years away from Earth.
