RE: NASA Finds Presence Of Sugar In Meteorites That Crashed To Earth

State dated about 7 billion years ago

Its state is dated from about 7 billion years ago, about 2.5 billion years before sun, Earth and rest of solar system formed. dust grains analyzed in research were formed before solar system's formation which is also kwn as “presolar grains”. small grains varied in sizes measuring from 2 to 30 micrometers in size.  researchers identified tiny grains inside meteorite by crushing fragments of rock and n separated component parts and described it smelling like rotten peanut butter. y have come up with a method to determine stardust's . Dust grains floating through get collided by high energy particles called cosmic rays. rays break grains into fragments.

Presence of sugar in meteorites

Meanwhile, NASA scientists have found presence of sugar in meteorites that crashed into Earth’s surface billions of years ago. According to researchers, latest findings can help look for more evidence of life in asteroids and justify that y help life ingredients. According to statement released by NASA on vember 20, a team of scientists has been able to discover ‘bio-essential’ sugars in meteorites, which consists of or biologically important compounds. According to ory of NASA scientists, chemical reactions which occur within asteroids can help in forming elements that are essential for sustaining life.
