Signs of Life Found in 4.5 Billion Year Old Meteorites
A group of scientists recently found evidence of the ingredients for life in two meteorites that landed on Earth some 20 years ago. The two specimens, named Zag and Monahans, were found when one crashed near a group of boys playing basketball in Texas, while the other crash landed in Morocco a few months later.
According to a study published in Science Advances the meteorites contain liquid water, carbon, oxygen, and nitrogen trapped inside salt crystals. One scientist compared the finding to a fly trapped in amber, as the meteorites are likely to be 4.5 billion years old and contain the basic elements necessary for life.
“This is really the first time we have found abundant organic matter also associated with liquid water that is really crucial to the origin of life and the origin of complex organic compounds in space,” said Queenie Chan, the study’s lead author and planetary scientist at The Open University in the U.K.
The meteorites are thought to have originated from two celestial bodies,Hebe and Ceres, that orbit in the asteroid belt between Mars and Jupiter. It is thought that, due to the similarity of the meteorites, the two may have impacted each other and mixed material.
NASA scientists have been intrigued by Ceres lately, continuing the Dawn spacecraft’s mission to study the dwarf planet two and a half years longer than intended.
Ceres is the largest object within the asteroid belt and could potentially harbor life. NASA believes that there once may have been a vast ocean on the dwarf planet and are sending Dawn within 20 miles of Ceres to study its surface.
There are still other preserved crystals from the meteorites that have yet to be studied by scientists who are hoping to find further evidence of liquid water and other life-supporting elements.

NASA Announces How It Will Report ET Contact
NASA Chief Bill Nelson says looking for extraterrestrial life is part of NASA’s mission, as its top scientists call for a detailed system for classifying ET life.
In a huge departure from the US government’s historical treatment of UFOs and possible ET life, NASA administrator Bill Nelson said in an interview with University of Virginia professor Larry Sabato, “[W]ho am I to say that planet Earth is the only location of a life form that is civilized and organized like ours?”
Meanwhile, top NASA scientists are calling for a scaled system for reporting any evidence of extraterrestrial life modeled after NASA’s progressive scale of Technological Readiness Level already in use for new spaceflight equipment.
Instead of the binary “life or no life” way of looking at off-planet discoveries, these scientists are suggesting a more nuanced way of reporting what they find. Cheryl Costa, retired journalist, UFO statistician, and author of the UFO Sightings Desk Reference, thinks it’s about time.
“I think it’s long overdue, they’ve been talking about this stuff for years. They know that there have been unidentified things in our skies since biblical times,” Costa said. “The fact that they’re finally owning up to the idea of classifying alien life. Their scale is going to have to run the range of organic molecules all the way up to sentient beings, so it needs to be a pretty big scale, and it’s nice to start seeing bonified scientists looking at this issue and saying ‘OK, we need to do this.'”
And what about NASA Administrator Bill Nelson’s comments?
“I think it’s refreshing that the NASA chief came out and said ‘Yeah, maybe’ on the UFOs and off-world life. I think they still know more than they’re telling us. I’m happy NASA is coming out with this stuff, I think they’re trying to feed it to us a little spoonful at a time. They don’t want to scare the populace,” Costa said.
