"In previous research, uracil and nicotinic acid were detected in the samples from asteroid Ryugu, but the other four nucleobases were absent. The difference in abundance and complexity of ...

Deposits Found on a Nearby Asteroid Point to Salty Water in the Outer Solar System Scientists have uncovered salt minerals in ...

Scientists recently completed computer simulations of what would happen to Earth if it were impacted by an asteroid with a ...

Rock and dust samples brought back to Earth from the asteroid Bennu contain organic matter and a variety of minerals crucial to the emergence of life ...

“Here we show that Bennu samples are volatile rich, with more carbon, nitrogen and ammonia than samples from asteroid Ryugu and most meteorites,” the scientists write. Importantly they also discovered ...

A previous sample from 162173 Ryugu, a diamond-shaped asteroid, contained myriad organic compounds, including vitamin B3 and uracil, the additional nucleobase used in RNA. Like Ryugu, Bennu is a ...

Researchers are unlocking secrets of our solar system by analyzing asteroid Bennu samples, some of the most pristine ever ...

In 2023, NASA’s OSIRIS-REx brought back to Earth 121 grams of material from asteroid Bennu. This is the largest sample ever ... this is much higher than what was found on Ryugu and in meteorites,” ...

Asteroids that orbit close to the Earth inevitably cause us some anxiety due to the even remote possibility of a collision.

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 ...

Overall, they write, a Bennu-type asteroid could lead to “severe environmental consequences,” reducing land photosynthesis by 36 percent and marine photosynthesis by 25 percent. That would in ...

uracil and nicotinic acid were detected in the samples from asteroid Ryugu, but the other four nucleobases were absent. The difference in abundance and complexity of N-heterocycles between Bennu ...
