Mark Your Calendars: A Rare Super Blood Wolf Moon Is Coming in January 2019

Get ready to do some serious skygazing in 2019. The new year will get off to a brilliant start when a rare reddish-orange body called a Super Blood Wolf Moon graces the sky in January, Forbes reports.

This phenomenon is actually the convergence of a few lunar events. For one, there's a total lunar eclipse, also known as a Blood Moon. This occurs when Earth comes between the Sun and Moon, causing the Sun’s light to bend towards the Moon—hence the spooky reddish hue. After January 2019, the next total lunar eclipse will occur in 2021.

Secondly, the Super Blood Wolf Moon takes place during a supermoon. This occurs when a moon’s full phase coincides with the point in its orbit when it comes closest to Earth. These two factors make it look 14 percent larger and 30 percent brighter than it normally does, according to Space.com.

Finally, a full moon in January has been called a Wolf Moon ever since colonial times, so that's where the "wolf" part of the name comes from.

If you’re in North America, you can expect to see the Super Blood Wolf Moon on January 20. Totality will occur around 9:12 p.m. PST or 12:12 a.m. EST on January 21, but Forbes suggests pulling up a chair an hour beforehand to watch the moon change from partial eclipse to total eclipse. The phenomenon will also be visible from South America and parts of western Europe, and the moon will don its crimson color for about an hour.

Other dazzling events to watch out for next year include a trio of supermoons on January 20/21, February 19, and March 21; the Eta Aquarids meteor shower on May 6/7; and a rare total solar eclipse on July 2.

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”).

Are Any of the Scientific Instruments Left on the Moon By the Apollo Astronauts Still Functional?

C Stuart Hardwick:

The retroreflectors left as part of the Apollo Lunar Ranging Experiment are still fully functional, though their reflective efficiency has diminished over the years.

This deterioration is actually now delivering valuable data. The deterioration has multiple causes including micrometeorite impacts and dust deposition on the reflector surface, and chemical degradation of the mirror surface on the underside—among other things.

As technology has advanced, ground station sensitivity has been repeatedly upgraded faster than the reflectors have deteriorated. As a result, measurements have gotten better, not worse, and measurements of the degradation itself have, among other things, lent support to the idea that static electric charge gives the moon an ephemeral periodic near-surface pseudo-atmosphere of electrically levitating dust.

No other Apollo experiments on the moon remain functional. All the missions except the first included experiment packages powered by radiothermoelectric generators (RTGs), which operated until they were ordered to shut down on September 30, 1977. This was done to save money, but also because by then the RTGs could no longer power the transmitters or any instruments, and the control room used to maintain contact was needed for other purposes.

Because of fears that some problem might force Apollo 11 to abort back to orbit soon after landing, Apollo 11 deployed a simplified experiment package including a solar-powered seismometer which failed after 21 days.
