The most dust-enshrouded black holes can completely stop X-rays and visible light escaping, but the same dust can be heated by a growing black hole and glow brightly at infrared wavelengths.

Above: Image of the object observed with the Hubble Space Telescope. It shows the emission in the ultraviolet part of the spectrum. Middle: Ultraviolet image of a local galaxy without a bulge and observed edge-on (IC 5249). The similarities are obvious. Bottom: The same galaxy IC 5249 observed in the visible part of the spectrum. The spatial scales of the three images are identical. Credit: ESA/Hubble

This image of the dusty debris disk surrounding the young star Fomalhaut is from Webb’s Mid-Infrared Instrument (MIRI). It reveals three nested belts extending out to 14 billion miles (23 billion kilometers) from the star. The inner belts were revealed by Webb for the first time. Credit: NASA, ESA, CSA, A.
