The Hubble Space Telescope has completed what NASA calls its “annual grand tour of the Solar System,” capturing stunning views of the four gas giants – Jupiter on 4 September; Saturn on 12 September; Uranus on 25 October; and Neptune on 7 September. Even though passing spacecraft and orbiters have sent back close-up views of all four worlds and multiple moons during visits over the past half century, the cold atmospheres of the gas giants are always changing. Using Hubble to keep tabs on Earth’s outer Solar System neighbours provides valuable insights into the dynamic processes at work under the cloudtops that shape weather patterns and seasons.

In a Hubble Space Telescope survey of 2,753 young, blue star clusters in the neighbouring Andromeda Galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass. The intensive survey was a unique collaboration between astronomers and “citizen scientists,” volunteers who provided invaluable help in analysing the mountain of data from Hubble.
