A rejuvenated Hubble Space Telescope, more powerful than ever, departed the space shuttle Tuesday and sailed off for new discoveries. "It's showtime for us now," program scientist Eric Smith said. Hubble -- considered to be at its prime after five days of repairs and upgrades -- was gently dropped overboard by the shuttle Atlantis astronauts, the last humans to see the 19-year-old observatory up close.

Researchers using the Hubble Space Telescope have found evidence for carbon dioxide in the atmosphere of a planet orbiting a star 63 light-years from Earth, the first demonstration that it is possible to monitor atmospheric chemistry on such distant exoplanets. Carbon dioxide could be associated with processes involving life, but in this case it probably is not because the Jupiter-sized planet, called HD 189733b, is too hot. Previous observations by Hubble and the Spitzer Space Telescope have also found water vapor and methane in the planet's atmosphere.

NASA has set a May date for its space shuttle mission to repair the Hubble Space Telescope for a final time. The space agency announced Thursday that it plans to launch the shuttle Atlantis on May 12 for what is to be an 11-day repair and upgrade mission to the $10-billion space telescope. NASA was going to fix Hubble in October, but weeks before the shuttle launch, a glitch in Hubble's science computer forced a delay. The problem was solved but NASA wants to deliver a new backup, and testing has caused delays.

Reaching a milestone in the search for Earth-like planets in the universe, two teams of astronomers say they have parted the curtains of space to take the first pictures of planets beyond our solar system. The first team, led by UC Berkeley researchers, used the Hubble Space Telescope to take a picture of a giant planet orbiting the star Fomalhaut, 25 light-years away. "It's almost science fiction," said Berkeley astronomer Eugene Chiang.

It was a good news, bad news day for NASA on Thursday as space agency managers announced that they had successfully restarted the broken Hubble Space Telescope, but acknowledged that they won't be ready to send a repair team to the 18-year-old instrument until May at the earliest. After reactivating two cameras on Hubble, scientists beamed its first pictures to Earth since a glitch idled the telescope several weeks ago.

NASA's efforts to get the ailing Hubble Space Telescope working again have hit a snag, and engineers are trying to figure out their next step. Officials had hoped to have the 18-year-old observatory back in business Friday, after it stopped sending pictures three weeks ago. But a pair of problems cropped up Thursday. First, a low-voltage power supply problem prevented one of the Hubble's cameras from rebooting properly, and then computer trouble struck, and all efforts ceased.

NASA engineers will begin trying today to bring the out-of-commission Hubble Space Telescope back online by switching to a backup system on a piece of equipment that relays data from the telescope to Earth. The science data formatter, which collects information from the various instruments aboard the telescope and packages it for delivery, broke down late last month.

An instrument that stores and transmits science data back to Earth has broken down on the Hubble Space Telescope, forcing NASA on Monday to postpone a long-scheduled repair mission to the ailing, 18-year-old telescope. The 136-pound control unit and science data formatter, which separates data from the telescope's five major science instruments into packets for transmission to scientists on Earth, broke down Saturday night, according to NASA scientists.
