NASA announced that the Hubble Space Telescope completed its 200,000th orbit around Earth.

At the milestone, Hubble monitored supernova Athena, which is expected to reappear because of gravitational lensing. Measuring its arrival times could help map the mass of galaxy cluster MACS J0417 and refine calculations of the universe’s expansion rate.
