This is an artistic illustration of the giant planet HR 8799b.
The planet is young and hot, at a temperature of 1,500° Fahrenheit (815° Celsius). It is slightly larger than Jupiter and may be 10 times more massive.
Analysis of the NICMOS data suggests the planet has water vapor in its atmosphere and is only partially cloud covered. It is not known if the planet has rings or moons, but circumplanetary debris is common among the outer planets of our solar system.
