April 24 marks the 21st anniversary of the orbiting of the Hubble telescope, deployed by space shuttle Discovery. After some false starts and costly repairs, it proved to be one of our greatest tools for peering into the cosmos. To commemorate the landmark achievement, NASA has released this image of two galaxies in the Andromeda constellation that swirl together, seemingly in the shape of a rose. Their boring, official name is Arp 273.
Happy Birthday, Hubble Telescope
