None of the world’s experts no what the strange spiral structure on the left is. Why the spiral glows is itself a mystery, with a leading hypothesis being illumination by light reflected from nearby stars.

The huge spiral spans about a third of a light year across and, winding four or five complete turns, has a regularity that has never been observed before.

NASA’s Hubble Space Telescope is back in business, ready to uncover new worlds, peer ever deeper into space, and even map the invisible backbone of the universe.

The first snapshots from the refurbished Hubble showcase the 19-year-old telescope’s new vision. Topping the list of exciting new views are colorful multi-wavelength pictures of far- flung galaxies, a densely packed star cluster, an eerie “pillar of creation,” and a “butterfly” nebula.

With the release of these images, astronomers have declared Hubble a fully rejuvenated observatory. Sen. Barbara A. Mikulski, D-Md., unveiled the images at NASA Headquarters in Washington, D.C., on Sept. 9, 2009.
