Study Suggests There's Water Beneath the Moon's Surface

Astronauts may not need to go far to find water outside Earth. As CNN reports, Brown University scientists Ralph E. Milliken and Shuai Li suspect there are significant amounts of water churning within the Moon’s interior.

Their findings, published in the journal Nature Geoscience, lean on the discovery of glass beads encased in the Moon’s volcanic rock deposits. As recently as 100 million years ago, the Earth’s moon was a hotbed of volcanic activity. Evidence of that volatile time can still be found in the ancient ash and volcanic rock that’s scattered across the surface.

Using satellite imagery, the researchers identified tiny water droplets preserved inside glass beads that formed in the volcanic deposits. While water makes up a small fraction of each bead, its presence suggests there’s significantly more of it making up the Moon’s mantle.

Milliken and Li aren't the first scientists to notice water in lunar rocks. In 2008, volcanic materials collected from the Moon during the Apollo missions of 1971 and 1972 were revealed to contain the same water-flecked glass beads that the Brown scientists made the basis of their recent study. They took their research further by analyzing images captured across the face of the Moon and quickly saw the Apollo rocks represented a larger trend. "The distribution of these water-rich deposits is the key thing," Milliken said in a press statement. "They're spread across the surface, which tells us that the water found in the Apollo samples isn't a one-off. Lunar pyroclastics seem to be universally water-rich, which suggests the same may be true of the mantle."

The study challenges what we know about the Moon's formation, which scientists think occurred when a planet-sized object slammed into the Earth 4.5 billion years ago. "The growing evidence for water inside the Moon suggests that water did somehow survive, or that it was brought in shortly after the impact by asteroids or comets before the Moon had completely solidified," Li said. "The exact origin of water in the lunar interior is still a big question."

The findings also hold exciting possibilities for the future of space travel. NASA scientists have already considered turning the Moon into a water station for astronauts on their way to Mars. If water on the celestial body is really as abundant as the evidence may suggest, figuring out how to access that resource will definitely be on NASA's agenda.

A Rare Blue Moon Will Light Up the Night Sky This Halloween

Wolves, werewolves, and people dressed as werewolves will have a bona fide full moon to howl at this Halloween. And it’s not just any full moon—it’s a blue moon.

What Is a Blue Moon?

Since a complete lunar cycle is 29.5 days long, this usually works out to one full moon per calendar month. If a full moon occurs on the first or second day of the month, however, there could technically be another one within the same month. When that happens—about once every 2.5 to 3 years, according to the Farmers’ Almanac—the second full moon is called a “blue moon.”

But up until the mid-20th century, blue moons had a different definition. The Maine Farmers’ Almanac and similar publications used to count full moons by season, so a year with 13 full moons meant that one season would have four (not three) full moons. To avoid messing with full moon nicknames that were tied to certain times of year (e.g. the “moon before Yule”), the third full moon in a season of four was named a “blue moon.”

In a 1943 column for Sky & Telescope, Laurence J. Lafleur mentioned that blue moons occur when a year has 13 full moons, but he didn’t go into detail about how the Maine Farmers’ Almanac determined which moon was, in fact, the blue one. Three years later, another Sky & Telescope author, James Hugh Pruett, wrote an article in which he incorrectly assumed that the blue moon was the second full moon in a month with two. The magazine repeated Pruett’s rule in future stories, and it eventually caught on with the general public.

Why Is It Called a “Blue Moon”?

Just like a pink moon isn’t pink and a worm moon isn’t crawling with worms, a blue moon isn’t actually blue. One theory holds that the name is derived from the Old English word belewe, or “to betray”—perhaps since blue moons betray the normal schedule of full moons. This lunar rarity is also said to be the origin of the phrase once in a blue moon.

The moon actually has appeared blue in the past. After a massive volcanic eruption, the ash in the sky can sometimes block red light particles, giving the moon a bluish tint. According to NASA, this happened after Indonesia’s Krakatoa erupted in 1883, and again when Mexico’s El Chichón spewed its molten guts a century later.

When Can I See October’s Blue Moon?

October's first full moon, the harvest moon, is coming on Thursday, October 1. The second one, the blue moon, will peak on Saturday, October 31, at 10:49 a.m. EST, so you’ll be able to see it before the sun rises or after it sets. Since a full moon on Halloween only happens once every 19 years or so, cross your fingers for clear skies that night.
