1. At one point, the Moon was entirely molten

2. Io only has volcanoes because the tidal forces from Jupiter (and Jupiter’s other moons) squish and pull tiny Io so much that its interior stays molten

3. At high enough pressures, hydrogen becomes a metallic liquid

4. There is an enormous cliff at the base of Olympus Mons, Mars’s (and the solar system’s) biggest volcano. It formed because the martian atmosphere rapidly becomes too thin to carry enough dust and sand to cause wind erosion, leaving the vast majority of the volcano essentially untouched

1. A tablespoon full of neutron star would weigh as much as a bull elephant

2. It takes millions of years for light to get from the center of the sun to the surface, then nine minutes to get from the surface of the sun to the Earth

1. Uhhhh perchlorate salts can adsorb so much water from the air that they turn into liquid brines

1. Neutrinos are so unlikely to interact with anything that we have to put neutrino detectors miles underground in old coal mines, because traveling through miles of solid rock is just about enough to get one or two of ‘em to chill out enough to be detected

2. By the way, the “detectors” are essentially olympic-size swimming pools with some science shit on the bottom

3. During the supernova of a truly massive blue giant star (those with masses >100 times the mass of our sun), internal pressures are so intense that the shockwave from the imploding core “stalls out.” As if that weren’t fucked up enough, the thing that eventually overcomes the inward pressure from the rest of the star and causes it to properly explode?
