In a rare event, the Moon got a massive new crater

A once-in-a-century crater formed on the moon right under our noses. A routine search of images from NASA’s Lunar Reconnaissance Orbiter camera found a fresh crater as wide as two American football fields, planetary scientist Mark Robinson reported March 17 at the Lunar and Planetary Sciences Meeting in The Woodlands, Texas.

The crater is 225 meters wide and formed in April or May 2024, Robinson said. According to predictions based on other lunar landmarks, a crater that big should form only once in 139 years. The discovery can help highlight the risks impacts pose to future astronauts.

One of the first craters the orbiter spotted after it began its mission in 2009 was 70 meters wide, said Robinson, of Houston-based spaceflight company Intuitive Machines. “I used to joke with folks … that now the bar has been set, you have to find a 100-meter crater,” he said. “Now, lo and behold, we have 225 meters.”

It's still all so BEYOND my level of comprehension! I live in the middle of NOWHERE, so we have NO light pollution. Some nights the stars seem so close, you could hit them with a broom!

And it makes me feel so small and insignificant in the, 'Grand Scheme of Things.'

But as Snoopy says:

One of the “fireballs” coming down in MI was described as having a green glow to it, which may indicate the presence of magnesium.

I truly envy you your dark skies!👍 I’m hoping for clear skies this weekend, our club is having a public star party. Hopefully we’ll have a lot of people.

“Hopefully we’ll have a lot of people.”

Star Party? How could you NOT have a good attendance! Tell them a few current ‘stars’ will be in attendance:

Jupiter! Venus! Aldebaran! The Pleiades Cluster!

You’ll be Golden. ;)

From what I have read is that Magnesium emits a blue-green or green color, and nickel also produces a green color.
FYI and freegards.
