On July 16 the Moon celebrated the 50th anniversary of the launch of Apollo 11 with a lunar eclipse visible from much of planet Earth.

15.07.2019
That's no sunspot. It's the International Space Station (ISS) caught passing in front of the Sun.

By contrast, the ISS is a complex and multi-spired mechanism, one of the largest and most sophisticated machines ever created by humanity.
