Watch the Biggest Explosion Ever Seen on the Moon
NASA scientists recorded the biggest explosion from a meteorite impact seen on the moon in eight years of monitoring.
The lunar burst was caused by a 40-kilogram boulder-sized rock slamming into the surface at about 90,000 kph. It generated a flash 10 times brighter than anything seen before, which came from the thermal glow of molten rock at the point of impact.
