The Best in Science News and Amazing Breakthroughs
A team led by researchers at MIT in the United States has discovered large molecules containing carbon in a distant interstellar cloud of gas and dust., shows that complex organic molecules likely existed in the cold, dark gas cloud that gave rise to our Solar System.
Pyrene is now the largest PAH detected in space, although it's what is known as a"small" or simple PAH, with 26 atoms. It was long thought such molecules could not survive the harsh environment of star formation when everything is bathed in radiation from the newborn suns, destroying complex molecules.
The amount of pyrene they found was significant. Importantly, this discovery in the Taurus molecular cloud suggests a lot of pyrene exists in the cold, dark molecular clouds that go on to form stars and solar systems.
