Mercury in the sky – level 2
On Monday, Mercury passed directly between Earth and the Sun. You could see it from the Americas, Europe, Africa and much of Asia. The transition lasted 7 hours.
The phenomenon happens 13 times every century. The last time it happened was 10 years ago in 2006 and the next time will be on November 11th, 2019.
The planet looked like a small black spot and it covered only a very small part of the sun, but looking at the sun with unprotected eyes can be very dangerous.
Difficult words: transition (when a planet moves in front of another thing in space), phenomenon (something which happens in nature), spot (a small round mark, a small circle).
You can read the original story and watch the video in the Level 3 section.
