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 ...

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 ...

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 ...

Although the chances of impact are slim, Bennu is still one of the most potentially hazardous known asteroids in our solar system, and we need to be prepared for what could come. A first-of-its ...

Bennu’s potential collision with Earth is a remote but unsettling possibility, according to a new study. Bennu is about 500 metres wide—taller than the Empire State Building and as wide as ...
