The 120 g of material came from the near-Earth asteroid 101955 Bennu ... Nucleobases have also been identified in the Bennu sample, but although chains of nucleobases are the molecular skeleton of RNA ...

the researchers also detected all five fundamental nucleobases—adenine, guanine, cytosine, thymine and uracil—crucial components of DNA and RNA. Tim McCoy, curator of meteorites at the ...

“Abundant ammonia and nitrogen-rich soluble organic matter in samples from asteroid (101955) Bennu” by Daniel P. Glavin, Jason P. Dworkin, Conel M. O’D. Alexander, José C. Aponte, Allison A. Baczynski ...

In 2018, NASA’s OSIRIS-REx mission reached asteroid 101955 Bennu. Two years later, the spacecraft snagged a sample of its surface, which has since been returned to Earth. Now, astronomers are ...

Secured inside that delivery was over 120 grams of material collected directly from 101955 Bennu, a large near-Earth asteroid that NASA ranks as one of the biggest potential impact threats we know ...

as well as all five nucleobases that life on Earth uses to store and transmit genetic instructions in DNA and RNA. “Asteroids provide a time capsule into our home planet’s history, and Bennu ...

The Bennu samples exhibit an equal abundance of left-handed and right-handed amino acid 4. Scientists found all five nucleobases – the genetic components of DNA and RNA – within the Bennu samples.

Dust and rocks from Bennu contained all five nucleobases—molecules that make up DNA and RNA—and 14 of the 20 amino acids in proteins. These organic molecules had been found in other asteroids. But ...

This image, taken by NASA's Osiris-Rex probe in December 2018, shows the asteroid Bennu. Scientists have identified 14 of the 20 amino acids used by terrestrial life, as well as the five nucleic acid ...
