Scientific observations resumed on the afternoon of Saturday 17 July. The telescope’s targets over the weekend included the unusual galaxies shown in the images above.
Images taken in a program led by Julianne Dalcanton of the University of Washington in Seattle show a galaxy with unusual extended spiral arms. In addition, Hubble has photographed a pair of colliding galaxies. Scientists also observed globular star clusters and auroras on Jupiter through a telescope.
The Hubble payload computer, which controls and coordinates the observatory’s onboard scientific instruments, suddenly came to a standstill on 13 June. When the main computer was unable to receive a signal from the payload computer, it automatically put Hubble’s scientific instruments into safe mode. This meant that the telescope would no longer be engaged in science while the mission specialists were analyzing the situation.
