The spiral galaxy M91 fills the frame of this Wide Field Camera 3 observation from the NASA/ESA Hubble Space Telescope. M91 lies approximately 55 million light-years from Earth in the constellation Coma Berenices and – as is evident in this image – is a barred spiral galaxy. While M91’s prominent bar makes for a spectacular galactic portrait, it also hides an astronomical monstrosity. Like our own galaxy, M91 contains a supermassive black hole at its center. A 2009 study using archival Hubble data found that this central black hole weighs somewhere between 9.6 and 38 million times as much as the Sun.

The faintest visible stars in this raw L’LORRI image are roughly 17th magnitude, 50,000 times fainter than the unaided human eye can see. Image brightness levels have been adjusted to enhance visibility of faint stars. The exposure time was 10 seconds. Keen observers will notice that the stars are slightly elongated in this relatively unprocessed image; the Lucy team has techniques to mitigate this effect, and the optical quality is sufficient for accomplishing the science goals of the mission.
