September in Space   Leave a comment

September’s usually a loaded month, for all sorts of reasons. Kids head back to school, there’s a big holiday capping off the traditional summer holiday, all the zucchini’s either ripened at once and your neighbors run from you as you clutch your harvest, chasing them, and we turn the season from boiling to pleasant.

There’s all sorts of things going on above our heads as well. We started off the month with a solar eclipse today, in Africa. That means in two weeks, we’re going to see a lunar eclipse on September 16.  Solar and lunar eclipses always appear in pairs, about two weeks apart. This time, the penumbral lunar eclipse will be visible throughout all of Europe, Asia, Australia, but not North and South America, except for the easternmost part of Brazil.

If you know your constellations, Scorpio is crawling back down southwest to get away for the winter. It’s taking with it a colorful trio of two planets, a star and one moon…but just for a day or two. Around the second week of September, you’ll see Antares, a big red star located in the upper portion of the constellation, Saturn to the upper right and Mars to the upper left. The moon on the half-shell will add its glow to the grouping.

September’s a fine month to spot the so-called Summer Triangle, a trio of constellations (The Swan, The Eagle and The Lyre) forming a jewel of a triangle consisting of two first magnitude stars and one zero magnitude: Vega (0.14 mag) in The Lyre, Altair (0.89 mag) in The Eagle and Deneb (1.33 mag). With luck, you can see this grouping almost all year round, but the best time for it is during the summer, when it’s nearly overhead in the Milky Way. Vega is especially close to Polaris, the North Star, and only goes below the horizon at latitudes 40 degrees for a handful of hours. The further north you go, the longer you can see it.

On Thursday, September 22, 2016 at 14:21 UTC, autumn officially begins in the northern hemisphere. That’s when you start thinking about how fast that summer went past, you still didn’t get to the beach, but that’s okay, because you can’t get into your bathing suit anyway. So why don’t you do yourself a favor? Toss on a sweater, take a chair and have a seat, looking up at the greatest gift we all have at our disposal: the heavens.
