SOFIA found clues in Comet Wirtanen’s ice grains that suggest water in comets and Earth’s oceans may share a common origin. Water is one of the major building blocks of life and Earth has an abundance of it, as 71 percent of its surface is covered by water, largely due to its expansive oceans. Now a new study theorizes that Earth's water may have been carried to our planet from ancient comets, millions of years ago.
The study, published in Astronomy and Astrophysics Letters, looked at data from NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) and found that there were similarities to the water contained on the comet Wirtanen and the water on Earth.
NASA scientists find Earth-like water in passing comet
Now that's what I call high-quality H2O.
The first interstellar object ever seen in our solar system, named ‘Oumuamua, is giving scientists a “This object was likely ejected from a distant star system,” said Elisa Quintana “What’ s interesting is that just this one object flying by so quickly can help us constrain some of our planet formation models.”
water in the Earth ’ s oceans, suggesting that water could have been carried to our planet by comets millions of years ago." Dominique Bockelée-Morvan, scientist at the Paris Observatory and the French National Center for Scientific Research and second author of the paper, said in a statement
“We have identified a vast reservoir of Earth-like water in the outer reaches of the solar system,” said the study's lead author, Darek Lis, a scientist at NASA’s Jet Propulsion Laboratory, in a statement. “Water was crucial for the development of life as we know it. We not only want to understand how Earth’s water was delivered, but also if this process could work in other planetary systems.”
The study's co-author, Dominique Bockelée-Morvan, a scientist at the Paris Observatory and the French National Center for Scientific Research, said that it's the first time researchers are able to "relate the heavy-to-regular water ratio of all comets to a single factor."
Also known as 46P, the Wirtanen comet was discovered by the American astronomer Carl Wirtanen in January 1948.
A ball of space mud just pelted Earth—and scientists couldn't be happier
We haven’t seen a rock like this in 50 years. In late April, the residents of Aguas Zarcas saw a giant fireball light up the sky as it hurtled towards the ground and broke up into hundreds of pieces, like this one above, in the atmosphere. Space science is always about what’s going on ‘out there’. Sometimes, astronomers must pay attention to what’s falling to Earth, too. That’s precisely what Arizona State University’s (ASU) Laurence Garvie is ready to do as he and his team scrutinize an extraterrestrial mud ball that rained down from the heavens last month and landed in a small town in Costa Rica.
A shocking new study suggests that the second interstellar object ever discovered, Comet 2I/Borisov, could be carrying water on it from beyond the Solar System. "In addition to detecting any potential threat some may pose to Earth , they may be the source of water on our planet and even the origin of
The cigar-shaped interstellar visitor to our solar system known as ‘Oumuamua could be the remnants of a larger body that was torn apart by its host star, according to researchers. The team say ‘Oumuamua could have formed from either a comet or a planet several times the size of Earth , but
The researchers found that the water contained an extra neutron inside one of the hydrogen atoms, chemically known as HDO; regular water is chemically known as H2O. The authors concluded that if comets contain the same ratio of water types as Earth's oceans, they may share a common origin.
"We may need to rethink how we study comets because water released from the ice grains appears to be a better indicator of the overall water ratio than the water released from surface ice," Bockelée-Morvan added.
SOFIA is a NASA lab aboard a modified Boeing 747SP jetliner that is able to carry a 106-inch diameter telescope. It is managed by NASA's Ames Research Center and is a joint project between NASA and the German Aerospace Center, DLR.

Russia's Soyuz MS-10 spacecraft carrying members of the International Space Station expedition 57/58 – Russian cosmonaut Alexey Ovchinin and NASA astronaut Nick Hague – blasts off to the ISS from the launch pad at the Russian-leased Baikonur Cosmodrome in Kazakhstan on Oct. 11. The mission was aborted shortly after launch due to an anomaly in the spacecraft.

This Sept. 21 view of the sun by Solar Dynamics Observatory uses two selected images taken at virtually the same time, but in different wavelengths of extreme ultraviolet light. The red-tinted image, which captures material not far above the Sun's surface, is good for revealing details along the edge of the Sun. The brown-tinted image shows two large coronal holes (darker areas) as well as some faint magnetic field lines and hints of solar activity (lighter areas), neither of which are apparent in the red image. This activity is occurring somewhat higher in the sun's corona.

‘Ad Astra’ Trailer Sees Brad Pitt Embark on an Interstellar Mission
Brad Pitt is launching into the stratosphere in the first trailer for “Ad Astra.” The dazzling sci-fi drama stars Pitt as an astronaut who travels on an interstellar mission to search for his missing father. The new footage begins with Pitt’s character, Roy McBride, praising his father, who never returned from a voyage to search for signs of extra-terrestrial life. “I do what I do because of my dad,” he says. “He was a hero. He gave his life for the pursuit of knowledge.
