NASA Finds Tryptophan, a Life-Related Molecule, on Asteroid Bennu
Researchers confirmed tryptophan in Bennu samples, raising detected protein-building amino acids to 15 of 20 used by life on Earth, enhancing knowledge of space chemistry.
- Tryptophan, an essential amino acid, has been found on the asteroid Bennu, reflecting the composition of the early solar system.
- The discovery stems from a sample collected by NASA's OSIRIS-REx mission, which landed on Bennu in 2020 and returned to Earth in 2023.
- The presence of tryptophan on Bennu suggests that asteroids might have delivered essential life ingredients to Earth early on.

Tryptophan Turns Up on Asteroid
Tryptophan, the amino acid often linked to post-turkey-dinner drowsiness, has been discovered on the asteroid Bennu, according to a new study. NASA's OSIRIS-REx mission collected a sample from Bennu in 2020, and it was returned to Earth in 2023 for analysis. The asteroid is of particular interest to scientists because...
By Jacopo Prisco, CNN. Tryptophan, the essential amino acid behind the Thanksgiving myth that eating turkey can make you sleepy, has been found on Bennu, a small asteroid that flies past our planet roughly every six years. The discovery comes from an unprecedented sample collected by NASA's OSIRIS-REx mission, which landed a spacecraft on the asteroid in 2020, captured 121.6 grams of rock and dust, and safely returned the sample to Earth in 2023…
Scientists find evidence that an asteroid contains tryptophan
By Jacopo Prisco, CNN (CNN) — Tryptophan, the essential amino acid behind the Thanksgiving myth that eating turkey can make you sleepy, has been found to exist on Bennu, a small asteroid that swings by our planet about every six years. The discovery stems from an unprecedented sample collected by NASA’s OSIRIS-REx mission, which landed a spacecraft on the asteroid in 2020, captured 4.3 ounces (121.6 grams) of rocks and dust, and safely returned …
