#McGetchin
月の新しいクレーターはMcGetchin:マクゲッチンというのですね。
NASAの月探査機LROが発見し、大きさは直径約222m、深さ約43m、2年前の4~5月の間に、小天体の衝突によって形成されたらしい。
クレーター名の由来は、月科学の先駆者 Tom McGetchin !!
・・・
でも222mでは大きな望遠鏡でも見えませんね😅

Wow: Giant new impact crater spotted on the Moon!

An asteroid the size of an apartment building hit the lunar surface in early 2024 & created 220-meter (730-foot) wide McGetchin crater.

It's "the largest contemporary impact crater found in the Solar System." 🧪🔭

#PPOD: A large new scar has appeared on the Moon. McGetchin crater formed sometime between April 11 and May 22, 2024, when an asteroid or comet roughly the size of a multi-story building slammed into the lunar surface. 🧪 🔭 🌕️

Scientists just discovered the largest ever new impact crater found—and it's on a surprisingly familiar (and heavily pock-marked) world.

Maybe I’m being naive, but isn’t the likelihood of this sort of thing happening quite a significant disincentive to attempting to colonise the moon?

Check out this new moon crater.

McGetchin Crater "...formed sometime in April or May of 2024, and is about as wide across as the two football fields placed end-to-end. The asteroid or comet that carved it was roughly the size of a small apartment building."

NASA scan discovers new, 'once in a century' Moon crater.

The crater, dubbed "McGetchin," measures 730 feet (222 meters) wide, and is believed to have been created in the spring of 2024 from a comet or asteroid colliding with the Moon

The moon has a new once-in-a-century crater! 🌕🧪

McGetchin crater is the largest new crater ever seen anywhere in the solar system, stretching 730 feet wide and 140 feet deep after an asteroid or comet the size of a 3-6 story building smacked into the lunar surface between April and May of 2024.

okay so i just read about this newly found crater on the moon, mcgetchin. it's 222 meters wide, like two football fields! only happens once every 132 years. the thermal imaging showing a cold spot around it is just wild. science is so cool.
Newly Discovered McGetchin Crater on the Moon is a 'Once-in-a-Lifetime' Discovery

The new lunar impact also created a big new cold spot on the Moon.

Seems that the incoming asteroid loosened up the Moon dust, so it doesn't hold heat as well. Nighttime temperatures around McGetchin crater are about 8 degrees C colder than its surroundings. 🧪🔭
