As if to advertise that astronomy is as easy as looking up, the first quarter moon will be near Jupiter high in the southern sky at nightfall this evening. Take a look outside at dusk and let the exquisitely-cut lunar half-pie point you to Jupiter.
Have telescope? Even a small glass will show all four of Jupiter’s brightest moons lined up in a neat row to the east of the planet around 9-10 p.m. 10x binoculars should easily show the two moons farthest from Jupiter tonight, Ganymede and Europa, as long as you can hold them steady.
Want more? Take that scope or binoculars and point them at the moon. First quarter phase brings hundreds of impact-sculpted craters into view especially in the southern half of the lunar disk. I’ve labeled the dark “seas” or “maria” (the Latin term) and three prominent craters. Use a magnification of 40x or higher for the best views.
Hope you had a great Astronomy Day. If you weren’t able to attend an event, consider the moon and Jupiter your own private show.
