Lunar dust collected by Apollo 17 astronauts in the 1970s has revealed that the moon is 40 million years older than previously believed.
After landing on the moon on December 11, 1972, NASA astronauts Eugene Cernan and Harrison Schmitt collected rocks and dust from the lunar surface. A new analysis of that sample detected zircon crystals and dated them to 4.46 billion years old. Previous estimates put the moon, formed by a massive celestial collision, at 4.425 billion years old.
The findings were published Monday in the journal Geochemical Perspectives Letters.

things I never knew before. For example, Jupiter is kind of like a big brother protecting earth from meteor strikes. Jupiter is big, so big that 1,300 Earths could fit inside of it. Jupiters immense size and a gravitational pull attracts meteors that otherwise might wipe out Earth or us. So many random events had to occur to make conditions on Earth conducive to life from its distance from the sun to the spinning on its axis after colliding with the moon that the fact we exists at all is miraculous. So we are all miracles. I just wish we could act like it
