Transit of Mercury Inspires Community-Based Learning
The transit of Mercury is an astronomical phenomenon in which Mercury comes between Earth and the Sun, and can be seen as a tiny black dot moving across the sun. This event was predicted by Johannes Kepler before it was observed visually. That observation was recorded in 1631. Today, we generally hear about astronomical events before they happen, often camping outside at night to see rare occurrences in the sky. How do astronomers predict events like the transit of Mercury with such accuracy? In short, advanced mathematics. Astronomers draw from concepts of Physics, and use Algebra, Geometry, Trigonometry and Calculus to make measurements of distances between objects in the sky, and predictions of when they will appear in various ways from Earth.
You don’t need to know anything about mathematics to appreciate the beauty of the sky, however. For centuries, the night sky remained largely a mystery to humans, and many myths emerged to explain the sun, moon, stars, and planets. Lunar and solar deities emerged in cultures across the world.
Whether you want to learn more about the mathematics of astronomy, write your own mythological explanations, or simply enjoy the beauty of the sky, you can attend various astronomy-themed events at the Springfield Museums this month. On Monday, May 9 from 10am-1pm, museum visitors can witness the first transit of Mercury since 2006. Check the Museums’ Facebook page to make sure the event is happening, as it is weather dependent. On Saturday, May 14 from 12-4pm, visitors can engage in safe sunspot viewing, and see a collection of meteorites. There will be hands-on activities for all ages, information about how craters are formed on the moon, and a space sensory bin for kids.
May 9th and 14th events are free with museum admission. Planetarium shows are $3 for adults, $2 for children ages 3-17, and free for members. 413-263-6800, ext. 318. 21 Edwards Street, Springfield, MA.
