Saturn is at opposition tonight, opposite the Sun as seen from Earth. It rises at sunset, is highest in the middle of the night, and sets at sunrise. The Seeliger effect brightening Saturn's rings should be at its strongest tonight.

Saturn comes to opposition. So does the Moon. Once the Moon is gone from the evening sky, try with your telescope for the autumn globular clusters Sagittifolia, Queen Anne's Lace, Watercress by the Stream, and Seaflower of the Deep.

Algol, the eclipsing variable star, has an eclipse tonight. It's normally the second-brightest star in Perseus at magnitude 2.1, but it should dip to magnitude 3.4 for a couple hours centered on its time of mid-eclipse, 11:22 p.m. EDT.

[NASA Astronomy Picture of the Day @apod]

If you went outside at the same time every day and took a picture that included the Sun, how would the Sun's position change? A visual answer to that question is an analemma, a composite image taken from the same spot at the same time over the course of a year. The featured analemma was composed from images taken every few days at noon near the village of Callanish in the Outer Hebrides in Scotland, UK. In the foreground are the Callanish Stones, a stone circle built around 2700 BC during humanity's Bronze Age. It is not known if the placement of the Callanish Stones has or had astronomical significance. The ultimate causes for the figure-8 shape of this and all analemmas are the tilt of the Earth axis and the ellipticity of the Earth's orbit around the Sun. At the solstices, the Sun will appear at the top or bottom of an analemma. The featured image was taken near the December solstice and so the Sun appears near the bottom. Equinoxes, however, correspond to analemma middle points -- not the intersection point. In two days there will be an equinox ("equal night"), when day and night are equal over all of planet Earth. Many cultures celebrate a change of season at an equinox.

Tonight, is NASA's International Observe the Moon Night. The Moon is in the Sagittarius Teapot, so grab a small telescope or pair of binoculars and enjoy the craggy terrain of Earths' delightful companion.

A partial lunar eclipse darkens the full Moon on Aug. 27. About 96% of the Moon slips into Earth's shadow, turning most of it red as our atmosphere filters sunlight. Begins 10:34pm ET Aug. 27, peaks 12:12am ET Aug. 28. What to look for: https://t.co/dlWHsPw8Zx 🌙
