New clues of space dust – | Iranian and world news

Astronomers and chemist star ( Astrochemirs) They examined perennial research to investigate and solve a simple question about whether galaxy dust is porous. These small dust seeds, which play an important role in astronomy, are found in the stars formation areas.

Galactic dust affects the way light travels in space and the formation of life -making blocks. The researchers found clues to dust porosity using various observations and missions. The EU’s Rosetta mission observed the comet 4P and found that dust particles were very fragile and spongy, and their porosity in some cases exceeds 5 %.

“Sponge particles can be eliminated when crossing the interstellar space with shocks and radiation,” says Professor McCostra. We have to remember astronomers about five years ago that there were molecules in space because it was thought to be a very violent environment. Today, star -fashioned is known as a science that raises fundamental questions about the formation of stars and the origin of life.

Alexei Pottapov of the University of Frederick Schiller, the senior author of the study, says: “If the seeds are porous, it means they will cover a much wider level than what we thought.” This alter the human understanding of the formation of molecules and evolution in space.
