Scientists have long queried how the complex molecules needed for life could have formed around the tumultuous and violent environment of the sun in its youth. " is theorized to have delivered the right stuff for life to Earth. But the question is, how did complex organic molecules containing elements like carbon, nitrogen, and oxygen come to be sealed in these meteorites in the first place?
"It is incredible to discover a new crucial role of dust traps in the formation of macromolecular matter that planets may need for hosting life," team member Paola Pinilla of the Mullard Space Science Laboratory at University College London told Space.com."Dust traps are beneficial regions for dust particles to grow to pebbles and planetesimals, which are the building blocks of planets.
The team wanted to know if the radiation that starlight brings to these areas could cause complex macromolecules to form, using computer modeling to test this idea. The model was based on observational data collected by the"Our research is a unique combination of astrochemistry, observations with ALMA, laboratory work, dust evolution, and the study of meteorites from our solar system," team member Nienke van der Marel of Leiden University said.
