Bright auroras on Jupiter are captured by Webb Space Telescope
- On December 25, 2023, Jonathan Nichols and his team from the University of Leicester captured detailed images of Jupiter's auroras using the James Webb Space Telescope near-infrared camera.
- The observations followed knowledge that Jupiter's strong magnetic field captures charged particles, including those from Io's volcanoes, producing auroras much brighter than Earth's.
- The auroral region showed rapid variability, with lights flickering by the second, and a brightness component observed by Webb lacked a clear counterpart in simultaneous ultraviolet Hubble images.
- Scientists observed that Jupiter's auroras are vastly more powerful than those on Earth and involve an unusual mix of large numbers of low-energy particles striking the atmosphere, prompting further investigation into the planet's magnetosphere.
- These findings provide new insights into Jupiter's magnetosphere and support future observations, including those by ESA’s Juice mission aiming to study Jupiter and its moons closely.

NASA's Webb telescope captures mesmerizing images of Jupiter's auroras
The James Webb Space Telescope, NASA’s successor to the Hubble Space Telescope, has captured new images of the auroras at Jupiter’s north pole. These massive auroras, caused by charged particles crashing into Jupiter’s atmosphere, are hundreds of times brighter than our own Aurora Borealis, and, for the first time, we can now see them in greater detail thanks to these new images. Auroras on Earth are caused by solar storms, which occur when char…
