NGC 4100, 67 million lightyears away in Ursa Major, appears from the Hubble Space Telescope’s line of sight to be stretched across the sky; an elongated spiral punctuated by sparkling blue newborn stars.
This image was captured by Hubble’s Advanced Camera for Surveys (ACS), installed in 2002 and still going strong thanks to a servicing mission in 2009.
