Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's essential ingredients.

Japanese scientists detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission. NASA’s OSIRIS-REx mission brought back 121.6 grams of asteroid Bennu,

NASA's OSIRIS-REx mission successfully returned samples from asteroid Bennu, revealing 14 of the 20 essential amino acids for life on Earth, along wit

All forms of Earth life have specific chemicals in their makeup, such as amino acids and sugars. Scientists have known that asteroids hold molecules believed to be the precursors to these chemicals. By studying the Bennu samples, they hope to gain more insight into how these ingredients could have evolved.

Scientists studying samples that NASA collected from the asteroid Bennu found a wide assortment of organic molecules that shed light on how life arose.

The building blocks of DNA have been found in samples returned to Earth from an asteroid, suggesting life rained down from space and could have formed elsewhere...

A recent discovery by NASA showed that a near-Earth asteroid, designated 2024 YR4, can collide on Earth with more than 1% chance. On Dec. 27, 2024, the NASA-funded Asteroid Terrestrial-impact Last Ale

Samples returned from an asteroid contain a surprising abundance of the basic ingredients of life. They were discovered to be rich in carbon, nitrogen and ammonia, with over 30 kinds of amino acids and the five nucleobases found in RNA and DNA. 1 The asteroid, Bennu, was targeted by a Nasa mission that returned a capsule to Earth in September 2023.

This marked Williams' ninth spacewalk and Wilmore's fifth. With this latest achievement, Williams now holds a total of 62 hours and 6 minutes of spacewalk time, placing her fourth on NASA's all-time list.

NASA’s efforts to protect astronauts from harmful microbes aboard the ISS have led to groundbreaking microbiology advancements. Using HEPA filters, water processing, and continuous monitoring, scientists now sequence DNA in space,

Scientists say the “building blocks for life” have been found inside the rubble of a 500-metre-wide asteroid in a breakthrough study.
