Way out in deep space, astronomers spot precursor of carbon based life
Finding the compounds around a protoplanetary disk – a giant hot swirling dense mass of gas and dust which forms around stars from which planets and asteroids can be born – raises questions about what precursors might be key for the development of life. Although UV radiation helps create methyl cations, it could also strip away the water needed for life as we know it.
Scientists, however, have found evidence from meteorites suggesting that the protoplanetary disk from which Earth was created was also subjected to intense UV rays – meaning it may have contained methyl cations but no water. Yet, somehow, life on Earth exists. How? "This is an open question. It could be that some water is present in ices inside grains in those UV irradiated disks, but so far we have not been able to detect it. We will be searching for it," Berne told us. ®
