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 have detected organic compounds and minerals necessary for life in the samples collected by the OSIRIS-REx mission from a near-Earth asteroid named Bennu.
When exposed to formaldehyde, which was also detected, ammonia can form amino acids, the building blocks of proteins. According to the study in Nature Astronom y, the team also found 14 of the 20 amino acids present in Earth-bound life in the Bennu sample. In addition, Bennu contains all five of the nucleotide bases present in DNA and RNA.
When asteroids like Bennu hit the young Earth, they could have provided a complete package of complex molecules and the ingredients essential to life, such as water, phosphate and ammonia. Together, these components could have seeded Earth’s initially barren landscape to produce a habitable world.
One Alabama woman was rudely awoken from a nap in 1954 when a meteorite came through her roof and hit her, leaving a big bruise.
In a triumph for NASA’s first asteroid sample return mission, new findings suggest that tiny bits of rock retrieved from the asteroid Bennu hold lingering traces of ancient salt water. The discovery hints that life-friendly chemistry could be far more common in space than astronomers previously thought.
About once every 2,000 years, a meteorite the size of a football field impacts Earth and causes huge damage, according to NASA. Meteor Crater in Arizona is considered the best-preserved meteorite ...
A doorbell camera on a Canadian home captured rare video and sound of a meteorite striking Earth as it crashed into a couple’s walkway.

There are 20 amino acids that create the proteins required for life on our planet — and scientists have now found exactly 14 of them on an asteroid millions of miles away. The asteroid in question, named Bennu, was the focus of a very dreamy NASA mission called OSIRIS-REx that launched in 2016.
