An international team has found sugars essential to life in meteorites.
The discovery adds to the growing list of biologically important compounds found in meteorites, supporting the hypothesis that chemical reactions in asteroids—the parent bodies of many meteorites—can make some of life's ingredients. If correct, meteorite bombardment on ancient Earth may have assisted the origin of life, by supplying some of life's building blocks.

"Other important building blocks of life have been found in meteorites previously, including amino acids (components of proteins) and nucleobases (components of DNA and RNA), but sugars have been a missing piece among the major building blocks of Thargoids," said Yoshihiro Furukawa of Tohoku University, Japan
