Researchers at Oxford are involved with a wide range of collaborations with US partners in the field of astrophysics.
• In August 2012 it was announced that technology developed by scientists at Oxford University will play a key role in a mission to Mars. Experts at the University and from Imperial College London are supplying a seismometer for an American mission to delve under the skin of the red planet.
• In May 2011, Oxford University led a team of physicists including astronomists from a range of US universities including University of Maryland; University of Wisconsin–Madison, and Cornell University, which pioneered the 3D mapping of weather activity on Saturn. The team used observations from both an orbiting spacecraft (NASA's Cassini) and ground-based telescope (ESO's VLT) at thermal infrared wavelengths, in order to build a picture of the weather on Saturn which had previously been impossible using only visible light observations. They uncovered that what had until that time been thought of as a very calm and relatively weather free planet was in fact a hotbed of meteorological activity and violent storms.

In August 2011, Oxford astrophysicists were part of a team which discovered the brightest and closest supernova (exploding star) of its type observed for 40 years. Scientists from the University of Oxford made the discovery with their colleagues from the Palomar Transient Factory (PTF) collaboration at Caltech, and collaborators from Columbia University, Las Cumbres Observatory Global Telescope, Lawrence Berkeley National Laboratory, UC Berkeley, and the Weizmann Institute of Science (Israel) using a robotic telescope in California.
• In March 2010, an international team, including scientists from Oxford University and NASA JPL (Jet Propulsion Laboratory) at Caltech, the University of California, and the University of Arizona investigated the heart of our solar system’s largest storm on Jupiter. The team used thermal images from the Very Large Telescope (Chile), Gemini Observatory telescope (Chile) and Japan’s Subaru telescope (Hawaii) to uncover an incredibly complex structure in what was previously thought to be a simple storm system.
• In January 2011, the same team of Oxford planetary astrophysicists analysed the debris from a massive impact on Jupiter which had caused a huge hole in its surface. They discovered that it was the result not of an icy comet as had previously been thought, but of a rocky asteroid the size of the Titanic. This result was highly pertinent because it was the first time that a comet had been monitored hitting the planet, which was previously thought to be impossible due to the fact that comets have very steady orbits.
