Fragments of the Murchison meteorite that crashed in 1969 have been analyzed by multiple laboratories. The Murchison meteorite broke apart and crashed on Earth 3.5 billion years ago, causing mass destruction. The 1969 data can be broken down into the following statements. More than 86 amino acids and 14,000 molecular compounds have been detected. The amino acids detected are a mixture of right-handed and left-handed molecules and include some known amino acids and several extraterrestrial amino acids. The concentration ratios of known amino acids are similar to the ratios found on Earth. The Murchison meteorite belongs to the class of meteorites that contain chemical signatures of the solar system around the time of the Sun’s formation.

Nutrient Growth Medium

It is a culture medium or nutrient broth for all kinds of microorganisms to grow properly and create their colony. This matrix provides support to increase the population of microbes through the method of cell proliferation. It is regarded as the food material for those organisms. It is a type of in vitro mechanism, in which the development of life is processed outside the host body. It can be solid, semi-solid, or liquid in nature. Different kinds of cells develop in different types of media.
