The discovery of all five nucleobases on Ryugu strengthens the idea that life’s molecular ingredients formed in space before reaching Earth.
A new study reports that samples from the asteroid Ryugu contain all five fundamental nucleobases, the molecular “letters” of life.
Tiny asteroid grains can preserve chemical clues about the ingredients that may have helped life emerge on Earth. The Ryugu material was returned from space in 2020 by the Japan Aerospace Exploration Agency’s (JAXA) Hayabusa2 mission.
In 2023, an international research team reported finding uracil, one of the nucleobases, in the Ryugu samples. Now, a study published on March 16, 2026, in Nature Astronomy by Japanese scientists has confirmed that all five nucleobases are present in the pristine asteroid material.
The finding suggests that these life related ingredients may have been common across the young Solar System…
Or it’s developed advanced enough life that they’re hiding from us until they deem us fit to join the intergalactic community.
Well that’s certainly a valid theory to explain where everyone is. In examination though, it’s not a terribly robust theory, because it assumes that the “galactic community” is a monolithic body with no bad actors. I mean even if whatever galactic council in charge decided not to interact with us, you don’t think that some third party wouldn’t just do it anyway? There’s always some jerk breaking the rules, always. And if there’s a whole galaxy full of individuals, there are a whole lot of chances for someone to be a bad actor. How do you control the actions of a whole galaxy of individuals?
Haha, www.lawofone.info/s/1 has the answer to that 😂
Perhaps with enough Jan Michael Vincents deployed in this quadrant…
