The Hubble Space Telescope is back in business and better than ever, reports NASA. which is posting fresh images online at www.nasa.gov/hubble.
"Topping the list of 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," says the online space-agency news service Science@NASA.
The new or improved instruments were installed or repaired during a mission back in May. New instruments include the Wide Field Camera 3 and the Cosmic Origins Spectrograph. Repaired were the Advanced Camera for Surveys and the Space Telescope Imaging Spectrograph. Also back in operation are the Near Infrared Camera and the Multi-Object Spectrometer.
The improvments make the Hubble gear more light sensitive and improve its efficiency, NASA says.
