NASA’s Spitzer Infrared Space Telescope has picked up the tryptophan signal amid a “stellar nursery” promising many star births.
Tryptophan is one of the 20 amino acids necessary for the formation of important proteins of living organisms on earth. The signal for this important living material appeared in the unique spectral lines of Spitzer’s observations as it traveled toward the molecular cloud of Perseus.

is a famous stellar nursery, 500 light years in diameter and containing many young stars, promising that there will be many “copies” of the Sun, giving rise to Earth-like planets.
Signal “YELLOW” It appears in area called IC248 of a giant cloud of gas and dust containing matter with a mass equivalent to 10,000 Suns.
“The evidence for tryptophan in the Perseus molecular cloud will encourage efforts to identify other amino acids in this and other star-forming regions.”” – sheet Space quoted researcher Ѕusana Iglesias-Groth from the Institute of Astrophysics of Ϲanarias (IAC – Spain).
What’s most interesting, she says, is that these protein building blocks are ubiquitous in the gas clouds where stars and planets will form, making it possible that it could become the key to the development of life on the distant planet later.
Such interstellar wandering amino acids have also been shown by many previous studies to be the source of life on Earth itself: they penetrate the nascent protoplanetary disk, seeding the materials that will form the earth or meteors will later fall on Earth.
The discovery is like a window into our star system’s past, as this stellar nursery is estimated to be only 2-3 million years old, meaning the objects it possesses are still too old. “new born” compared to our 4.5 billion year old world.
The results have just been published on Royal Astronomical Society Monthly Notices.
