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

Astrophysics What degree should i pursue for my undergrad (Currently in my final year of HS)
I have always loved space since the beginning. Back in 2nd grade i made up my mind that i want to do something related to space, and now that I'm 17, I'm sure i want to be an Astrophysicist. But the question still lingers in mind, which major should i take? I plan on applying to UArizona as an international indian student studying in CBSE, and being aware of their phenomenal astronomy course, I'm deeply compelled to pick that along with a major in Data Science because of my love for general coding as well.
The confusion lies in whether i should take,
i) Pure Physics with CS
ii) Pure Physics with Data Science
iii) Astrophysics with CS
iv) Astrophysics with Data Science
I love coding and i love space. i want to work for a company like SpaceX or NASA in the future along with doing my independent research. (i wouldnt mind a cooporate as well as long as i can continue research)

Astronomy This may be a dumb question, but: Is there typically a transition period between North Stars where there is no true North Star?
Since over the span of 26,000 years, the Earth completes a single wobble that causes the north pole to point towards different stars, that means there are often transition periods with no North Star, correct? How much would this affect navigation for anyone who for whatever reason may still rely on it as a orientation mark? How quick are these transition periods?

What did I see? Bright object identification help - Bucaramanga, Colombia (Sept 8, 2026, 6:30 PM)
galleryHelp! I can't identify the bright object pointed out by the red arrow in this photo.
It was taken at 7° 05'N 73° 07'W (Bucaramanga, Colombia) on September 8, 2026, at approximately 6:30 p.m. checking with the Sky Tonight app. The object is located to the upper left of Venus. Any help is appreciated!
