Anthony Remijan: So these organic molecules that we find on the Earth are actually out there in space.

You are listening to astronomer Anthony Remijan with the National Radio Astronomy Observatory in Charlottesville, Virginia. Remijan is talking about large molecules that formed in space – ones that might be the building blocks of all life here on Earth.

Anthony Remijan: [---1---]

Remijan and his colleagues pointed radio telescope dishes toward the center of our galaxy, a region called Sagittarius B2 North. [---2---]

Anthony Remijan: And ome of the largest molecules are things you find every single day in your own house: ethylene glycol which is an antifreeze, acetic acid which is in vinegar — even things like formic acid, which you find in bee and ant stings.

Anthony Remijan: And we think that the molecules that formed in the interstellar medium got bottled up into comets and asteroids and meteorites, and then actually seeded early planets like the Earth.

And these are the basic chemical elements that build up larger molecules that we find in biology today, things like amino acids and proteins. They found faint radiation from 720 different space molecules, many of which are still unidentified. Remijan said that these precursors to life might have formed in the interstellar medium, the clouds of dust and gas between stars.
