Two meteor showers peak at the end of July: the Southern Delta Aquarids, best seen in the Southern Hemisphere in the constellation Aquarius, and the Alpha Capricornids, which are visible from both hemispheres in Capricorn.

With the moon around 40 percent full, the already-faint Southern Delta Aquarids, sometimes spelled Aquariids, may be difficult to see. The Alpha Capricornids will be bright, but they rarely create more than five meteors an hour. Here’s what you need to know about watching meteor showers.

In 2021, Jared Isaacman, the billionaire founder of the payments processor Shift4, took three people to space with him for a mission called Inspiration4. In 2022, he announced that there would be additional flights. This year, with a new crew in the SpaceX Dragon capsule, Mr. Isaacman wants to fly to a higher orbit and attempt a spacewalk. The Polaris Program announced the mission will launch no earlier than July 31.

A partial lunar eclipse occurs when the sun, Earth and moon are positioned almost, but not quite, in a straight line. Unlike the penumbral eclipse in March, this time the moon will pass through a portion of the umbra, or the darkest part of Earth’s shadow cast by the sun. As a result, a part of the lunar surface will be completely obscured to viewers on Earth’s night side, which in this case will include the Americas, Africa and Europe.

The autumnal equinox is one of two points in Earth’s orbit where the sun creates equal periods of daytime and nighttime across the globe. Many mark it as the first day of the fall. See what it looks like from space.
