Meteorite bits have always fallen on earth. Scientists are convinced that it is this debris carrying organic life that seeded the planet to what it turned out to be. That is why there is a continuous search to recover any bits fallen to earth. It has to be done quickly as exposure to earth degrades them. Consequently, today’s weather systems can track hail size bits quite efficiently and able to track them down effectively. Every now and again they are found by meteorite hunters as in this case a couple of years ago. Subsequently, when he came across it he could see it was fresh and quite pristine. Hence the excitement to get it into lab conditions for analysis. Now we have the results of that analysis.
It is exciting to discover these building blocks of life and analyse what they contain. As they are all different and you never know what will be found in them.
