Astronomers have produced a remarkable new image of Jupiter, tracing the glowing regions of warmth that lurk beneath the gas giant's cloud tops.
The picture was captured in infrared by the Gemini North Telescope in Hawaii, and is one of the sharpest observations of the planet ever made from the ground.
To achieve the resolution, scientists used a technique called "lucky imaging" which scrubs out the blurring effect of looking through Earth's turbulent atmosphere.
This method involves acquiring multiple exposures of the target and only keeping those segments of an image where that turbulence is at a minimum.
When all the "lucky shots" are put together in a mosaic, a clarity emerges that's beyond just the single exposure.
