Beneath a crater on the moon lies what could be the remains of a colossal, metal-rich asteroid that hit our moon 4 billion years ago.
From NY Mag:
It sits 180 miles beneath the South Pole-Aitken basin — one of the solar system’s largest impact craters, and the moon’s oldest, at over 4 billion years — a massive dent spanning some 1,550 miles on the far side of the moon. (It’s also where China landed its Chang’e 4 lunar rover in January.) Publishing in Geophysical Research Letters, the Baylor scientists have two theories for the origin of the huge subterranean blob. It could be the leftovers of dense oxides created in the last years when the moon’s surface was an ocean of magma — a theory that relies on the giant-impact hypothesis, when an impactor the size of Mars may have collided into a magma-covered Earth, ejecting magma into orbit that became the surface of the moon.

A couple weeks after the crash, NASA’s Lunar Reconnaissance Orbiter orbited over the area and NASA has released images […]
“We must return to the Moon—this time to stay.”
On Sunday, UK-based backyard astrophotographer Szabolcs Nagy captured a series of images of the International Space Station transiting the moon and combined them in the captivating GIF above. Nagy’s tools, seen below in the parking lot where he set up for the shoot, were a Skywatcher 250/1200 FlexTube Ddobson telescope and Zwo ASI224MC camera. ISS: […]

Fried foods are a weakness for many of us. There’s nothing quite like that extra crisp crackle on chicken, fries or onion rings. And for years, our arteries have been paying for the privilege. Lately, the air fryer has been a godsend for those who love the fried stuff but love their body too. If […]
