😴 NASA astronauts sleeping

BBC presenter Lewis Vaughan posted the video on social media - "It's much scarier than I imagined," he admitted

A clear example of how we see the moon

The closest galaxy to ours, Andromeda, is 2.52 million years away ✨ The Milky Way and Andromeda are travelling towards each other at great speeds (Andromeda's speed is 300 km/s and the Milky Way's is 552 km/s)

The Milky Way and Andromeda are travelling towards each other at great speeds (Andromeda's speed is 300 km/s and the Milky Way's is 552 km/s). Scientists are sure that they will collide in 2.5-3 billion years.

The Oort Cloud is a hypothetical spherical region of the Solar System that is the source of long-period comets.

This is what the transit of Mercury on 9 May 2016, seen by the AIA telescope at the Solar Dynamics Observatory, looks like.

Tidal destruction💥

The rings of gas giants are thought to be formed from the material of former satellites that came too close to the body of the giant and were destroyed by its tidal forces.

There is a certain orbital height (the Roche limit) below which the side of the satellite facing the planet experiences an outward gravitational force greater than the gravitational force at the centre of the satellite. As a result, the moon crumbles🪨

As it collapses, the particles of the former satellite are distributed along its orbit. After some time, the remains of the satellite form a ring

On 14 December 1972, three NASA astronauts Eugene Cernan, Harrison Schmitt, and Ronald Ellwyn lifted off from the surface of the satellite, ending the last lunar mission, Apollo 17 of the Apollo Expedition.

No one else has flown to the moon since.
