The galaxy M74 in a combined view at optical and infrared frequencies seen by the Hubble and Webb space telescopes, respectively

ESA has published images of the galaxy M74, nicknamed the Phantom Galaxy, captured by the Hubble and James Webb space telescopes with the addition of a combination between them. It’s a synergy that takes advantage of Hubble’s sensitivity to optical frequencies and Webb’s sensitivity to infrared frequencies. This allows to appreciate different details of a spiral galaxy that is practically visible face-on from the Earth and therefore an excellent object of study. Combining observations obtained with instruments that work in different electromagnetic bands is important Webb starts showing the great results it can offer in this type of study as well.
