Meteorites that do not experience high temperatures at any point in their existence provide a good record of complex chemistry present when or before our solar system was formed. So researchers have examined individual amino acids in these meteorites, many of which are not in present-day organisms. In Physics of Fluids, researchers show the existence of a systematic group of amino acid polymers across several members of the oldest meteorite class, the CV3 type.

A long time ago – roughly 4.5 billion years – our sun and solar system formed over the short time span of 200,000 years. That is the conclusion of a group of Lawrence Livermore National Laboratory (LLNL) scientists after looking at isotopes of the element molybdenum found on meteorites.
Researchers from UC San Diego and Brookhaven Laboratory in New York investigated a diverse population of meteorites. Among the 15 pieces of comets and asteroids studied, they found two with superconductive grains.
