      I have done a project which used images of nearby galaxies (and things called globular clusters in them – basically big collections of stars) which were taken by one of the most famous satellites – the Hubble Space Telescope. I used it to show that all the globular clusters seemed to have the same size no matter how bright they are – that tells something really interesting about how they formed. It’s also interesting, because it could potentially be used to measure distances to galaxies.

      I haven’t had them sent only to me, but I have used plenty of data from satellites. Mostly in fact from satellites that orbit Mars.

      I used spectroscopic data to analyse the gases in the atmosphere, but also look at pretty pictures.

      You can look at some here http://hirise.lpl.arizona.edu/

      I use really high resolution pictures of the earth taken by satellites, to track rock outcrops that I might not be able to get to on foot, and to also look at changes in forests and algal blooms in the ocean.

      Here’s an example – showing a wildfire in Yellowstone in America.

      They change the colours so different features are easy to see. The very bright green shows where there are towns.

      I’ve never looked at space from a satellite, but I have used satellites which are used to look at the ground. The project I was working on was to to compare measurements of how much energy was sent out from the Earth (measured by the satellite) with what was predicted by climate change models.
