In a groundbreaking collaboration, scientists from the University of Reading in the UK have been remotely photographing Jupiter for a vital NASA mission. The researchers, led by Dr. James O’Donoghue, have been using the Keck telescope in Hawaii to capture images of the gas giant without ever leaving their lab. This innovative approach to space research marks a new era of access to powerful telescopes, as scientists no longer need to travel to remote observatories to conduct their work. The images, which are downloaded within seconds of being taken, are being used in support of the ongoing NASA Juno spacecraft mission, providing valuable real time data to complement the spacecraft’s close up observations.

The primary purpose of this remote photography is to study Jupiter's atmosphere, with a particular focus on the spectacular auroras that occur at its poles. By taking images of the planet in infrared, the scientists are able to measure Jupiter's temperature and observe how its brightness changes. These powerful light shows are driven by hundreds of trillions of watts of energy, and monitoring them helps researchers understand how energy flows through Jupiter's atmosphere and how the planet interacts with its surrounding space environment. The observations provide a crucial ground based perspective that complements the data gathered by the Juno spacecraft, which has been orbiting Jupiter since 2016.

The use of remote technology is a significant step forward for planetary astronomy. In the past, scientists had to travel to special facilities or even to Hawaii to make these kinds of observations, a process that was both costly and time consuming. The ability to control a massive telescope from a research lab in Reading, UK, streamlines the research process and makes it more accessible. This technological advancement allows for more frequent and timely observations, enabling scientists to respond quickly to new developments in their research and to capture transient events in the planet's dynamic atmosphere. The photographs recovered from the observations not only show bright auroras but also reveal a unique detail: a black circle in front of Jupiter, which is actually the moon Callisto, appearing black because it is so bright it saturates the pixels of the infrared camera.

The collaboration between the University of Reading and NASA highlights a new model for international space research. By combining the data from the Juno spacecraft, which provides close up details of Jupiter, with the broader, long term observations from a powerful ground based telescope, scientists are gaining a more complete and comprehensive understanding of the giant planet. This approach not only maximizes the scientific return of space missions but also fosters greater collaboration among the global scientific community. The success of this project serves as a powerful example of how remote operations and international partnerships can unlock new discoveries and push the boundaries of space exploration from right here on Earth.
