ARP PIX NASA Hubble

This undated handout photo provided by NASA, taken by the Hubble Space Telescope, shows a pair of gravitationally interacting galaxies called Arp 147. The Hubble Space Telescope is working again, taking stunning cosmic photos after a one-month breakdown. The Hubble Space Telescope Science Institute in Baltimore said the $10 billion telescope is as good as it was before a shutdown in late September. That glitch scotched plans for spacewalking astronauts to upgrade the telescope this month. (AP Photo/NASA)
