How do astronomers understand galaxies that are so far away that they may appear as a simple point source, even when observed with the most powerful telescopes? One proven technique is to study local analogues, galaxies that might have similar properties but are close enough to resolve their structures. A study like this was underway when researchers discovered something extraordinary – their observation was 10 times stronger than predicted.

Researchers at the University of Texas San Antonio using observations from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, found that the dust surrounding active, ravenous black holes are much more compact than previously thought.
