Barred 30. spiral galaxy NGC 6217 This is the first image of a celestial object taken with the then newly repaired Advanced Camera for Surveys. The camera was restored to operation during the STS-125 Servicing Mission. The barred spiral galaxy NGC 6217 was photographed on 13 June and 8 July 2009, as part of the initial testing and calibration of Hubble’s ACS. The galaxy lies up to 90 million light-years away in the north circumpolar constellation Ursa Major. Credit: NASA, ESA and the Hubble SM4 ERO Team 31. Backlit dust lanes in NGC 7049 The Hubble Space Telescope captured this image of NGC 7049 in the constellation of Indus, in the southern sky. A family of globular clusters appears as glittering spots dusted around the galaxy halo. Astronomers study the globular clusters in NGC 7049 to learn more about its formation and evolution. The dust lanes, which appear as a lacy web, are dramatically backlit by the millions of stars in the halo of NGC 7049. Credit: NASA, ESA and W. Harris (McMaster University, Ontario, Canada)
