- <p>Super photos prove the repairs were successful
- </p>
- <p>By Michael D. Lemonick

- <p> Shortly after midnight on Dec. 18, just five days after the
- shuttle Endeavour returned from the daring mission to repair
- the Hubble telescope, scientists secretly put the refurbished
- instrument to its first test. They ordered the Hubble to point
- toward a bright star and beam its image to Earth. Anxiously,
- they crowded around a computer screen at the Space Telescope
- Science Institute in Baltimore, Maryland, as they waited for
- the picture to appear. The Endeavour astronauts had installed
- the telescope's corrective lenses and other equipment perfectly.
- But it wasn't certain that the devices would actually work.
- As the star's image came up on the screen, the scientists stared
- for a second--then burst into cheers. The Hubble, hobbled
- for nearly four years by an improperly ground mirror, was going
- to be as good as new.
- </p>
- <p> In fact, said ASA administrator Daniel Goldin, presenting the
- first images from the born-again telescope at a press conference
- last week, "it's better than new. The telescope now gathers
- light four times as efficiently as it did before the repairs."
- Its eyesight is so sharp, say scientists, that if it were sitting
- in Washington, it could spot a firefly in Tokyo.
- </p>
- <p> That's not hard to believe, considering the before and after
- pictures NASA unveiled. Blurred blobs have turned into sharp,
- clean images of galaxies, super-novas and stars. But, says senior
- project scientist David Leckrone, "these are the very first
- test images. We're not pushing the telescope to its limits yet."
- As they do, scientists will almost certainly be able to start
- solving some of astronomy's greatest mysteries: How old is the
- universe? Do giant black holes lurk at the cores of galaxies?
- How did the galaxies get formed? Are there planets circling
- other stars? And besides searching for those answers, the Hubble
- will treat astronomers to a clear, close view of a space spectacular
- in July: the collision between comet Shoemaker-Levy 1993e and
- Jupiter.
