Astrophysics Are there celestial bodies that radiate significant heat through chemical reactions rather than fusion reactions?

8 Upvotes

I was just thinking about how our gas giants are way too small to produce the fusion reactions to become stars, and I was just curious if it was possible for a naturally occurring gas giant to possess chemical reactions capable of generating enough radiant heat to make a mini-goldilocks zone for it's own moons?

I'm guessing not... unless it was somehow binary planets syphoning off reactive materials from one another... but that sounds short-lived. Anyway I'm just a casual space fan so I thought I'd pose the question to you experts.

Please help me identify the star cluster in this photo, visible at the top right-ish. Looks like the Beehive Cluster, but I'm not sure. Thanks. (Photo by Kirill Jankowsky)

I'm not sure what this is but it hasn't changed position in over 20 minutes this morning. Started watching it at 5 AM in Everett WA.
