Interstellar Comet 3I/ATLAS Is Spewing Water Like a Cosmic Fire Hydrant

Interstellar Comet 3I/ATLAS Is Spewing Water Like a Cosmic Fire Hydrant

Comet 3I/Atlas continues to be full of surprises. As well as being only the third interstellar object ever detected, new analysis shows it is producing hydroxyl (OH) emissions, with these compounds betraying the presence of water on its surface. This discovery was made by a team of researchers at Auburn University in Alabama using NASA’s Neil Gehrels Swift Observatory, and was described in a study published in The Astrophysical Journal Letters.

Hydroxyl compounds are detectable via the ultraviolet signature they produce. But on Earth, a lot of UV wavelengths are blocked by the atmosphere, which is why the researchers had to use the Neil Gehrels Swift Observatory—a space telescope free from interference experienced by observatories on Earth.

Water is present in virtually every comet seen in the solar system, so much so that the chemical and physical reactions of water are used to measure, catalog, and track these celestial objects and how they react to the heat of the sun. Finding it on 3I/ATLAS means being able to study its characteristics using the same scale used for regular comets, and this information could in future be useful data for studying the processes of comets that originate in other star systems as well.

“When we detect water—or even its faint ultraviolet echo, OH—from an interstellar comet, we’re reading a note from another planetary system,” said Dennis Bodewits, an Auburn University physicist who collaborated on the research, in a press statement. “It tells us that the ingredients for life’s chemistry are not unique to our own.”

Comets are frozen hunks of rock, gases, and dust that usually orbit stars (the exceptions being the three interstellar objects found so far). When they’re far away from a star, they’re completely frozen, but as they get closer, solar radiation causes their frozen elements to heat up and sublimate—turn from solid into gas—with some of this material emitted from the comet’s nucleus thanks to the star’s energy, forming a “tail.”

But with 3I/ATLAS, data collected revealed an unexpected detail: OH production by the comet was already happening far away from the sun—when the comet was more than three times farther from the sun than the Earth—in a region of the solar system where temperatures normally aren’t sufficient to easily produce the sublimation of ice. Already at that distance, however, 3I/ATLAS was leaking water at the rate of about 40 kilograms per second, a flow comparable—the study authors explain—to that of a “hydrant at maximum power.”

This detail would seem to indicate a more complex structure than what is usually observed in comets in the solar system. It could, for example, be explained by the presence of small fragments of ice detaching from the comet’s nucleus, and which are then vaporized by the heat of sunlight, going on to feed a gaseous cloud that surrounds the celestial body. This is something that has so far been observed only in a small number of extremely distant comets, and which could provide valuable information about the processes from which 3I/ATLAS originated.

“Every interstellar comet so far has been a surprise,” said Zexi Xing, an Auburn University researcher and coauthor of the discovery, in a press statement. “‘Oumuamua was dry, Borisov was rich in carbon monoxide, and now ATLAS is giving up water at a distance where we didn’t expect it. Each one is rewriting what we thought we knew about how planets and comets form around stars.”

Today’s Wordle answer should be easy to solve if you love coziness.

If you just want to be told today’s word, you can jump to the bottom of this article for today’s Wordle solution revealed. But if you’d rather solve it yourself, keep reading for some clues, tips, and strategies to assist you.

Where did Wordle come from?

Originally created by engineer Josh Wardle as a gift for his partner, Wordle rapidly spread to become an international phenomenon, with thousands of people around the globe playing every day. Alternate Wordle versions created by fans also sprang up, including battle royale Squabble, music identification game Heardle, and variations like Dordle and Quordle that make you guess multiple words at once

Wordle eventually became so popular that it was purchased by the New York Times, and TikTok creators even livestream themselves playing.

What’s the best Wordle starting word?

The best Wordle starting word is the one that speaks to you.
