Fun Fact of the Day: When the Earth’s shadow sweeps across the lunar landscape, the temperature drops radically. In fact, the resulting “thermal shock” may cause lunar rocks to crumble and gas to escape from within the moon.
Fun Fact of the Day: 252 million years ago, the Siberian Traps, erupted and lasted less than 1 million years but left behind Earth’s biggest “large igneous province,” a pile of lava and other volcanic rocks about 720,000 cubic miles (3 million cubic kilometers) in volume.
Fun Fact of the Day: Time on Earth is actually slowing down. Due to tidal friction from the sun and moon, the solar day is lengthening by 1.7 milliseconds each century as the Earth’s rotation slows down.
Fun Fact of the Day: While it seems counterintuitive, Earth is actually closest to the sun in December, even though winter solstice is the shortest day of the year.
