๐Ÿ—“ โ›ฑ SUMMER IS HERE! (Astronomically Speaking)

21 June 2022 by Bob O'Hara

Today (June 21st) is the June solsticeย โ€” we call it the summer solstice in the northern hemisphere, but in the southern hemisphere it’s the winter solstice. The summer solstice is (in astronomical terms) the first day of summer, just as the winter solstice is (in astronomical terms) the first day of winter.

Whenever you’re investigating things temporal or calendrical, timeanddate.com is always a good place to start:

  • โžข June Solstice: Shortest & Longest Day of the Year (timeanddate.com)

The seasons occur because the earth’s axis of daily rotation is not quite perpendicular to the plane of the earth’s annual orbit around the sun (it’s tilted by about 23ยบ). The two solstices occur at the points in the orbit when the axis of rotation is tilted most directly away from the sun (in December, on the first day of northern-hemisphere winter) and most directly toward the sun (in June, on the first day of northern-hemisphere summer). The two equinoxes, in March and September, occur when the earth’s axis of rotation is “sideways” to the sun (so to speak), making the intervals of daylight and darkness equal (or very nearly so).

The two equinoxes (March and September) and the two solstices (June and December) are defined with respect to the earth’s position in its annual orbit around the sun. (Image: timeanddate.com.)

NASA has a fun educational crossword puzzle for kids that’s filled with seasonal vocabularyย โ€” solstices, equinoxes, and more.

You can print out your own copy at NASA’s “For Educators” website. And you can find many more technical facts and figures about solstices and equinoxes in your recommended homeschool almanac.

What calendrical events and astronomical alignments will you be marking in your homeschool this Hercules Term?ย ๐Ÿ˜Š

โกโ€…Watchers of the skies: Teaching your students about the seasons and the stars is one of the simplest and most enduring gifts you can give them. Your recommended River Houses astronomy guide has descriptions and maps of all the constellations that point out the seasonal highlights, and the astronomical section of your recommended world atlas has beautiful large charts of both celestial hemispheres. Why not find a dark-sky spot near you this month and spend some quality homeschool time beneath the starry vault.ย ๐Ÿ”ญ
