HAT-P-39 b is a sizzling hot Jupiter that orbits its star, HAT-P-39, discovered back in 2012 using the trusty transit method. This gas giant is a bit of a cosmic show-off, crossing in front of its star and providing us with a delightful dimming light show captured by a 2K CCD sensor here on Earth. Found thanks to the HATNet project, it’s a fantastic example of how ground-based telescopes can reveal distant worlds. While it’s too hot and massive for life as we know it, HAT-P-39 b thrills astronomers with its blazing close-in orbit, making it a fascinating stop on any interstellar tour of fiery exoplanets!
