There are more trees on Earth than stars in the Milky Way. A major global estimate put the planet’s tree count at about three trillion, while NASA gives the Milky Way’s star count as roughly 100 to 400 billion.

The most cited global estimate puts the number of trees on Earth at about three trillion. NASA gives the Milky Way somewhere between 100 and 400 billion stars. Three trillion is more than seven times the high end of that range, so there are indeed more trees on Earth than stars in our galaxy. Both […]

The bootprints left by the Apollo astronauts will still be sitting on the Moon a million years from now, because there is no wind and no rain to wear them away.

The claim is true, and a million years is plausible, though not guaranteed for every individual print. The Apollo tracks, first pressed into the lunar surface in 1969, will almost certainly still be visible in some form a million years from now. There is no wind on the Moon and no rain, so the forces […]
