HAT-P-2b sits 440 light-years away in the constellation Hercules, and by any normal measure it should not exist: surface temperatures swinging between 1000 and 2000 degrees Celsius, gravity 15 times Earth's, and a year that lasts just 5.6 days. Astronomers at the Harvard-Smithsonian Center for Astrophysics found it using HATNet, a network of automated telescopes that scans the Northern Hemisphere sky nightly for planets crossing in front of their stars, and it turned out to be the most massive planet known outside our solar system at the time. This National Geographic film uses that discovery as an entry point into a wider survey of exoplanets that break the rules planets are supposed to follow: oversized gas giants, worlds locked into scorching orbits, and systems that look nothing like our own. The footage leans on animation and telescope data to render worlds no camera has actually photographed, framing each one as evidence that the galaxy's planet-building process is stranger and more varied than our own eight examples suggested.
