How LONG is the Earth? The answer is amazing!

“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?

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.

Comet NEOWISE and noctilucent clouds – something we’ve never seen before

Russian space agency Roscosmos published spectacular photos of Comet NEOWISE (C/2020 F3) and noctilucent clouds or polar mesospheric clouds (PMCs) above our beautiful planet Earth. This is something we’ve never seen before. Forming about 45-55 miles (75-90 km) above polar regions in summer, noctilucent clouds are Earth’s uppermost clouds and only visible around twilight. PMCs are composed of ice crystals that glow bright blue or white when reflecting sunlight. The photos are taken by the Russian cosmonaut Ivan Vagner.
