Observatories require electricity and computing power to process data from deep space. Is there a way to make them run greener?
, according to the new study. That’s equal to burning 1,655 railcars of coal, using the same EPA calculator. The Very Large Telescope, which is based in Paranal, Chile, has an estimated carbon footprint of 540,000 metric tons of COSome might ask why astronomers would worry about the size of their carbon footprint when other industries are much worse.
To come up with the new carbon footprint figures, the authors used estimates from previous papers showing how much energy was consumed during construction and launch , and projections of the energy cost of operating them over their expected lifetimes. The authors say their figures are good approximations, but not perfect. Some uncertainty arises because the results change depending on whether the previous estimates were derived using the mass of the object or the carbon cost of building it.
