A solar eclipse, one of the year's best meteor showers, Venus at its brightest in the evening sky, and a lunar eclipse to close out the month.

That's “What’s Up” for August.

On Aug. 12, a total solar eclipse crosses northern Russia, Greenland, Iceland, and northern Spain, with a small corner of Portugal inside the path of totality.

In parts of the United States, from Alaska to North Carolina, the eclipse is partial. The Moon will take only a small bite out of the Sun, and the amount of coverage will vary with location.

Remember to watch safely. Use certified eclipse glasses or a safe solar viewer any time any part of the Sun is visible. Regular sunglasses are not safe. And never use binoculars, a telescope, or a camera without a solar filter made for the front of the optics.

Later that same night, the Perseid meteor shower will light up the sky, peaking the evening of Aug. 12 into the early morning hours of the 13th. And with a New Moon arriving on the 12th, the skies will be ideally dark.

The Perseids happen every year when Earth passes through a debris stream left behind by Comet Swift-Tuttle. As those tiny bits of comet dust hit our atmosphere at high speed, they burn up as bright streaks of light.

To view this meteor shower, look toward the northeast once it's fully dark and watch for the constellation Perseus to clear the horizon. This is where the meteors originate, but let your eyes wander, because they can flash across any part of the sky.

For the best view, stay out late as the stars climb higher, find a dark open spot, and give your eyes 30 minutes to adjust.

Aug. 14-16, Venus reaches its greatest eastern elongation, which is its widest apparent separation from the Sun during this evening appearance.

Look low in the western sky shortly after sunset for the bright object that will outshine every star around it. Through a telescope after sunset, Venus will look close to half lit, like a tiny lunar phase.

On the night of Aug. 27, continuing into Aug. 28 for some time zones, the Full Moon slips through Earth's shadow, resulting in a partial lunar eclipse. It will be visible from much of North and South America and parts of Europe and Africa.

At maximum eclipse, about 93% of the Moon's diameter will be inside Earth's dark central shadow, called the umbra. The Moon will not be completely covered, but it can look dramatically darkened, with a rusty, coppery tint along the covered edge.

Unlike a solar eclipse, a lunar eclipse is safe to watch with just your eyes. Binoculars or a small telescope can give you a closer view of Earth's curved shadow moving across the Moon.

Here are the phases of the Moon for August.
