A map of the Faraday rotation measure—which encodes the magnetic field strength and topology affecting passing radiation—based on cosmological simulations reproduces Galactic and local structure on the scale of individual star-forming clouds.
Harnessing the power of citizen science and machine learning, this study takes in 20 years of Hubble Space Telescope images, of which 2.7% show satellite streaks, and predicts that this fraction will increase by up to an order of magnitude in the next decade.
