Recently, dust inclusions found on the meteorite from 1969 have been reexamined. This led to a new discovery. These dust inclusions turned out to contain stardust grains which originated from a supernova. The interesting part is that they originate from a supernova older than our Milky Way solar system. These molecules are vital and play an important role in the emergence of life. The team had originally isolated some silicon carbide stardust grains and using a sensitive spectrometer analyzed them. What they found was beyond their expectations. It turned out that these samples had an unusual isotopic distribution, which does not fit with any current models found in stars. This discovery was very much coincidental, as the detected grains are extremely rare and take only 100 millionth part of the meteorite. Some hypothesis about the sulfur molecules have been made in the past, however the proof was finally found only recently. This discovery provides an inexhaustible source of information about the formation of our solar system.
It is discoveries like this that determine the nature of astronomy as a science. This is the evidence that helps take a deeper look into the galaxy and the stars above us. The theory of the creation of the universe is basically a guess. Scientists have given some proof as to it, however, discoveries of the smallest materials, like this one, can give a whole new point of view on the issue. New discoveries in the field of astronomy make it an extremely interesting subject. With so much still unknown and at questions, one has a vast field for play.
