Far beyond Pluto, trillions of cold comets circle the sun in a lazy swarm called the Oort Cloud. A new simulation indicates what this comet-cloud looks like: a loose spiral that resembles a miniature galaxy.

The Artemis II crew has recently been immersed in flight operations reviews and simulating @NASA_Orion’s return to Earth.

The crew wants to extend a special thank you to all the different teams across the country that are coming together to build the @NASA_SLS rocket.

The crew of Apollo 14 found it difficult to sleep - partly due to the angle at which they landed.
They felt they were slipping down into a crater, and Ed Mitchell would regularly lift the blinds to check they were not.
Wonderful clarity in this small section of the full panorama.

Ever noticed how the Moon seems HUGE when it’s near the horizon but smaller when it’s overhead?

Trick of the eye or something more? Scientists have debated this for 2,000+ years, and we still don’t have a definitive answer! Find out what we do know: https://t.co/tW0dRmCOT5

[Encyclopaedia Britannica @Britannica]

Encyclopædia Britannica will continue to use ‘Gulf of Mexico’ for a few reasons:

-We serve an international audience, a majority of which is outside the U.S.

-The Gulf of Mexico is an international body of water, and the U.S.’s authority to rename it is ambiguous.
