With better computer systems comes more battery imagery. Or at least thats true the majority of the time. Supercomputers are extraordinarily proficient at image processing, so its usually worth it when a new algorithm comes along that they can turn their attention to. Thats exactly what happened with an algorithm recently developed by Ph.D. trainee Frits Sweijen and his colleagues at Leiden University. They utilized a number of supercomputers image processing power to mimic and boost the resolution of radio images caught by the International LOFAR telescope.. Mr. Sweijen and his team utilized their algorithm to fix an especially thorny issue in radio astronomy– how to filter out sound from our atmosphere. The sun charges the Earths environment with particles that hinder radio signals, making it challenging to catch a clear image of the radio-emitting phenomena with ground-based radio telescopes..

They utilized the Academic Leiden Interdisciplinary Cluster Environment (ALICE) and Spider supercomputing platforms to parallelize the estimations that resulted in much greater resolution images that had previously been readily available. The resolution was so high, in fact, that one section, which was a location about the size of a moon, would have as many pixels in it as a normal radio map of the complete sky.

Realistically, that is not that much time. With battery imagery also comes better science.
