10 things about the 2017 eclipse you must know

Hello, Readers!

Firstly, check out IU’s plans for the eclipse right here: go.iu.edu/solareclipse Everyone in Indiana will see a partial eclipse.

(1) Do not look at the Sun during the partial eclipse, UNLESS you have the right solar eclipse viewing glasses. Check here if you have the right glasses: https://eclipse.aas.org/eye-safety/iso-certification Look at the map above to find out if you are in the totality or not.

(2) You can look at the sky during totality. If you are under the path of totality, you still CANNOT look at the Sun at all times, except for the duration of totality. The totality is when the Moon completely blocks the Sun. In 2017, the totality may last from 1 second to up to 2 minutes 40 seconds.

(3) About Glasses. Trivial but important: do not look up and then wear glasses. Always wear glasses with your head down, and then look upwards toward the sky and find the Sun.

(4) Eclipse without glasses. If you don’t have glasses, here is a way to make your own pinhole camera:

Leaves act as excellent pinhole cameras.

(5) This eclipse is the first Transcontinental Total Solar Eclipse in the USA in 99 years. Interstate highway system didn’t exist the last time.

(6) Largest Organized Mass Transportation. The eclipse will be the largest organized mass transportation in the US history. Expect the traffic on all major highways to be crazy. Plan to have sufficient gas. Carry extra food. Finding restrooms will be hard.

(7) Eclipse in 2024. Another total solar eclipse will come to the United States in 2024.

(8) Total solar eclipses are rare for a given physical location. Los Angeles will see the next total solar eclipse in the year 3290. On April 1st.

(9) The eclipse is evidence that the Earth, the Moon, and the Sun are round. The event is an appreciation of the astronomical size scales, the Sun is so far away (~8.5 light minutes) that it appears to be the same size as the Moon. The Moon is so little that about 50 of those can fit inside Earth, and the Earth is so tiny that more than a million Earth can fit inside the Sun.

(10) Eclipses have occurred since the formation of the solar system, but total solar eclipses will stop happening after a long time, once the Moon recedes sufficiently father away from us. Yes, the Moon’s orbit is getting larger, at a rate of about 38 millimeters per year. At this rate, the Moon’s distance from the Sun will always be astronomically high.
