A NASA spacecraft has returned asteroid samples that hold not only the pristine building blocks for life but also the salty remains of an ancient water world.
NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission. It's a win for alien life.
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.
The asteroid, designated 2024 YR4, jumped to the top of NASA's risk chart, with a slim but measurable chance of striking Earth in just seven years.
Samples of asteroid Bennu contain molecules that suggest the "conditions necessary for life" were widespread across the early solar system, according to NASA.
Scientists from NASA and other institutions who have been analyzing the Bennu asteroid sample that returned to Earth last September found molecules, including amino acids, which are essential ingredients of life as we know it.
Rock and dust samples from the Bennu asteroid contain molecules that are the "key to life" on Earth, NASA officials announced on Wednesday.
The discovery is a capstone achievement for NASA, which went to great lengths to secure and deliver asteroid samples from asteroid Bennu in 2020.
YR4 is about half the width of a football field and will pass very close to Earth on December 22, 2032, coming within approximately 106,200 km
Scientists from the National Aeronautics and Space Administration (Nasa) say they have spotted an asteroid that could smash into the Earth on December 22, 2032. The space rock, named Asteroid 2024 YR4,
Could a massive asteroid, nearly as tall as the Statue of Liberty, collide with Earth in 2030? While it sounds like a sci-fi disaster, scientists assure us that the chances of impact are extremely low.
