800M years ago it was raining asteroids on the moon according to scientists

The team presented their results in a paper titled “Asteroid shower on the Earth-Moon system immediately before the Cryogenian period revealed by KAGUYA.” 

On Earth, ancient crater impacts are erased. Volcanism, erosions, and other processes take care of that. But we do know that asteroids strike Earth, and that they can be deadly. The Chicxulub impact from about 66 million years ago illustrates that succintly.

The Chicxulub impactor was about 10 – 15 km (6 – 10 miles) in diameter. Studies show that we can expect an asteroid about the size of the Chicxulub impactor to strike Earth about once every 100 million years. But since that evidence is hard to come by, the team from Osaka University examined craters on the Moon, to understand what role asteroids have played in Earth’s history.

The team looked at craters over 20 km (12.5 miles) in diameter, and studied 59 of them. They examined smaller craters between 0.1-1 km (330 – 3300 ft) in diameter that were in the ejecta of the larger craters.

From there the team looked at data from the Apollo missions to the surface of the Moon. Radiometric dating of impact melt spherules from Apollo samples show that “sporadic meteoroid bombardment occurred across the whole Moon at approximately 800?Ma,” the authors write in their paper.

They say that these sporadic meteor showers may have delivered large amounts of phosphorous to Earth, affecting the terrestrial environment.

Bloody hooker

800M years ago it was raining...

Me: Gaga just won’t let up on the ROM promo! Serving it ancient asteroid style :giveup:

 

On topic:

The moon is so mysterious. Even our solar system is mysterious :duck:

This mutual gaze was a “longing to touch” or a "pre-coitus" stare.
