NASA’s new space telescope opened its huge, gold-plated, flower-shaped mirror Saturday, the final step in the observatory’s dramatic unfurling.<\/p>\n

The last portion of the 21-foot (6.5-meter) mirror swung into place at flight controllers’ command, completing the unfolding of the James Webb Space Telescope.<\/p>\n

“I’m emotional about it. What an amazing milestone. We see that beautiful pattern out there in the sky now,” said Thomas Zurbuchen, chief of NASA’s science missions.<\/p>\n

More powerful than the Hubble Space Telescope, the $10 billion Webb will scan the cosmos for light streaming from the first stars and galaxies formed 13.7 billion years ago. To accomplish this, NASA had to outfit Webb with the largest and most sensitive mirror ever launched\u2014its “golden eye,” as scientists call it.<\/p>\n

Webb is so big that it had to be folded orgami-style to fit in the rocket that soared from South America two weeks ago. The riskiest operation occurred earlier in the week, when the tennis court-size sunshield unfurled, providing subzero shade for the mirror and infrared detectors.<\/p>\n

Flight controllers in Baltimore began opening the primary mirror Friday, unfolding the left side like a drop-leaf table. The mood was even more upbeat Saturday, with peppy music filling the control room as the right side snapp<\/a>ed into place. After applauding, the controllers immedia<\/a>tely got back to work, latching everything down. They jumped to their feet and cheered when the operation was finally complete two hours later.<\/p>\n
