Starship Asterisk*

Does anyone out there know why, in May 5th's APOD, Jupiter's poles seem to be glowing? The edges of Jupiter fade to black everywhere else, indicating full-on sunlight, but the poles come to a knife edge with strong color. There seems to be a light source that is not the sun. I've followed the link to the Hubble data, but it does not address my question. Thanks.

Ah, the reason the poles seem to glow is because this image is a composite of a visible light image and a near-infrared image. That pale glow covering the poles is infrared light from high-altitude haze in Jupiter's atmosphere. It's not a true-colour image of Jupiter as we would see it with our own eyes.

Hello all

I have seen the images of jupiter so many times and have only realized the extra red dot.

It only 7 years old.
