A Half-Blood Thunder Moon Will Light Up Tonight’s Sky

Today, July 16, 2019, marks 50 years since NASA launched the Apollo 11 lunar mission. In case you needed another reason to look up at the sky on this date, tonight's Moon will be a special one. It's the only full moon of July, and in some parts of the world, it will appear partially eclipsed, making for a rare half-blood thunder moon, according to Space.com.

The meaning of the name thunder moon has nothing to do with lightening and storm clouds. The full moon of each month of the calendar year is given a special nickname from folklore. January's is a wolf moon, March's is a worm moon, and June's is a strawberry moon. The full moon that appears in July is commonly called a thunder moon, because thunderstorms are frequent this time of year, but it can also be referred to as buck moon because July is when deer antlers are at their fullest.

There's another factor that makes tonight's Moon worth watching. Starting at 2:43 p.m. EDT, the Moon will enter a partial lunar eclipse. That means part of the full moon will pass through the shadow of the Earth, making one section of it appear darker than the rest. A full lunar eclipse is known as a blood moon due to the reddish hue it takes on in our planet's shadow. Tonight's event isn't a full eclipse, so it's being called a half-blood moon even though it may not take on a coppery tone. The partial lunar eclipse will reach its peak at 5:30 p.m. EDT, and conclude at 8:17 p.m. Unfortunately that means the eclipse won't be visible from the U.S., but spectators in Europe, Africa, South America, and parts of Asia will get to see the full show.

July is shaping up to be an exciting month for stargazers. On July 9, Saturn reached opposition, making it look especially large and bright in the night sky. The planet is no longer at peak visibility, but it will be easy to spot with the naked eye from now through September. If you're already planning at looking up at the Moon tonight, here's how to find Saturn at the same time.

A Super Pink Moon—the Biggest Supermoon of 2020—Is Coming In April

The sky has already given us several spectacular reasons to look up this year. In addition to a few beautiful full moons, we’ve also gotten opportunities to see the moon share a “kiss” with Venus and even make Mars briefly disappear.

In early April, avid sky-gazers are in for another treat—a super pink moon, the biggest supermoon of 2020. This full moon is considered a supermoon because it coincides with the moon’s perigee, or the point in the moon’s monthly orbit when it’s closest to Earth. According to EarthSky, the lunar perigee occurs on April 7 at 2:08 p.m. EST, and the peak of the full moon follows just hours later, at 10:35 p.m. EST.

How a supermoon is different.

Since the super pink moon will be closer to Earth than any other full moon this year, it will be 2020’s biggest and brightest. It’s also the second of three consecutive supermoons, sandwiched between March’s worm moon and May’s flower moon. Because supermoons only appear about 7 percent bigger and 15 percent brighter than regular full moons, you might not notice a huge difference—but even the most ordinary full moon is pretty breathtaking, so the super pink moon is worth an upward glance when night falls on April 7.

The meaning of pink moon.

Despite its name, the super pink moon will still shine with a normal golden-white glow. As The Old Farmer’s Almanac explains, April’s full moon derives its misleading moniker from an eastern North American wildflower called Phlox subulata, or moss pink, that usually blooms in early April. It’s also called the paschal moon, since its timing helps the Catholic Church set the date for Easter (the word paschal means “of or relating to Easter”).

A Full Worm Moon Is Coming

You don’t have to be an early bird to catch a glimpse of next week’s full worm moon—it’ll reach its peak during the day on Monday, March 9, so feel free to look up any time after sundown that night.

As The Old Farmer’s Almanac explains, March’s full moon is known as the “worm moon” because the ground is usually soft enough for earthworm casts (small piles of worm excrement) to start appearing on the surface, and other signs of spring soon follow. It’s also sometimes called the “full sap moon,” since March is also the time of year when sugar maples start leaking sap.

This year’s worm or sap moon is a supermoon, meaning it occurs around the time of the Moon’s perigee, or the point during the Moon’s monthly orbit when it’s closest to Earth. Because March’s full moon is especially close to Earth, it’ll look slightly bigger and brighter than a regular full moon. It won’t technically be 2020’s biggest and brightest—according to EarthSky, that designation will go to the supermoon on April 8, which peaks even closer to the moon’s perigee.

That said, April’s supermoon will only be about 230 miles closer to us than March’s, so they’re definitely both worth an upward glance. May’s full moon, which peaks on May 7, finishes off the trifecta of 2020 full supermoons.

If you’re worried about a series of three consecutive supersized moons wreaking havoc on people’s behavior even more than normal moons allegedly do, rest easy: That’s probably just a myth.
