“How long is the Earth” is a weird question – but what if you cut it up into Minecraft-sized 1-meter cubes and lay them in a line through space, how far would the Earth stretch? It is a thought experiment and in the video published by the astrophysicist (and a famous poker player!) Liv Boeree below, we can get the answer and it is mind-blowing: the Earth would stretch across the entire Milky Way (more than 100,000 light-years!) if its volume is laid out in a line of 1-meter cubes.
Apollo Flight Journal channel published a detailed video that shows every second of the complete descent and landing of Apollo 11, the spaceflight that first landed humans on the Moon on July 20, 1969. The video combines data from the onboard computer for altitude and pitch angle (you can see both altitude and pitch angle every second), 16mm film that was shot throughout the descent at 6 frames per second.

Many of us have had the misfortune to encounter mosquitoes at one time or another. If we’re lucky, we’ve only experienced them from the perspective of being something of an annoyance.
