About this image

This graph plots small changes in the infrared brightness of a super-Jupiter as measured by the Hubble Space Telescope. The S-shaped curve is extrapolated from the data points. Its sinusoidal shape suggests that brightness changes are a result of a 10-hour rotation period (horizontal axis). The vertical axis shows small changes in brightness. This would mean that the planet likely has patchy clouds that influence the amount of infrared radiation observed as the planet rotates. At a distance of 170 light-years from Earth, the planet is too far away for Hubble to actually resolve atmospheric structure.
