SETI meteor expert says New Jersey meteorite expands known prebiotic chemistry
"So we've we've looked at this rock and we've found that this particular rock was very finely crushed. It was just pummeled and smashed and there were these little bits of pieces that came from the subsurface of the asteroid. And that gave us the first sort of window into what chemistry you get in on that type of an object."
About this episode
NewsNation’s Jesse Weber interviews Dr Peter Jenniskens, a senior research scientist and meteor expert at the SETI Institute, about a meteorite that struck a home in Hillsborough, New Jersey after a fireball was seen across the US Northeast. Weber frames the story around claims from scientists that the rock contains “alien world chemistry”, including amino acids and other organic or prebiotic molecules, while stressing that this is not evidence of living organisms.
Jenniskens says the meteorite was recovered immediately and preserved by the homeowners, which he argues made it unusually “pristine” for laboratory study. He describes the specimen as belonging to a rare class — he says only 22 are known — and claims it contains tiny pieces of material from the original surface of the parent world, as well as fragments that he describes as coming from beneath the asteroid’s surface. He says the rock appears “finely crushed” from past impacts and that analysis widened the “flavour” of compounds and chemistry that could have been delivered to early Earth.
Pressed on whether meteorites might carry life, Jenniskens argues meteorites are more likely to deliver starting materials than living organisms, and he suggests Earth was capable of generating life once supplied with the necessary compounds. The segment ends with Weber describing the meteorite findings as a notable step in understanding life’s origins and the search for life elsewhere.
Key takeaways
- A meteorite struck a home in Hillsborough, New Jersey after a widely observed fireball event.
- Host Jesse Weber says scientists reported amino acids and other prebiotic molecules in the meteorite, not evidence of living organisms.
- Dr Peter Jenniskens says rapid recovery and preservation left the meteorite unusually “pristine” for analysis.
- Jenniskens describes the rock as a rare meteorite type and says it contains material linked to the parent body’s surface and subsurface.
- He says the meteorite was heavily crushed by past impacts, offering a “window” into the chemistry of that kind of object.
- Jenniskens argues meteorites are more plausible sources of water and organic building blocks than carriers of life itself.
