NASA is tracking a truck-sized asteroid which is set to hurtle by Earth today at many times the velocity of a speeding bullet. The space rock—dubbed "2025 BV5"—is estimated by NASA's Jet Propulsion Laboratory to be some 26 feet across.

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.

NASA says there's a tiny chance it could collide with Earth, and it's much too soon to know where that impact could be.

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 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.

Molecules friendly to life have been found in samples of the asteroid Bennu, which NASA collected with a robotic probe five years ago.

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.

BS4 may be anywhere between 17 and 40 feet across, and will approach at about twice the distance between the Earth and moon.

Rock and dust samples from the Bennu asteroid contain molecules that are the "key to life" on Earth, NASA officials announced on Wednesday.

The asteroid, dubbed 2024 YR4, was detected by NASA's Asteroid Terrestrial-impact Last Alert System on Dec. 27, 2024. According to researchers, it has about a 1-in-83 chance of impacting our planet in 2032.

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