The NASA/ESA Hubble Space Telescope has captured a striking new photo of the edge-on spiral galaxy UGC 11537.

UGC 11537 is located approximately 217.5 million light-years away in the constellation of Aquila.

Also known as IRAS 20160-0018 or LEDA 64458, the galaxy lies close to the plane of the Milky Way.

“Being so close to the starry band of the Milky Way means that foreground stars from our own Galaxy have crept into the image,” the Hubble astronomers said.

“The two prominent stars in front of UGC 11537 are interlopers from within the Milky Way.”

“These bright foreground stars are surrounded by diffraction spikes — imaging artifacts caused by starlight interacting with Hubble’s inner structure.”

The new image of UGC 11537 is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum.

Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

“WFC3 captured the tightly wound spiral arms swirling around the heart of UGC 11537 at infrared and visible wavelengths, showing both the bright bands of stars and the dark clouds of dust threading throughout the galaxy,” the researchers said.

“This image came from a set of observations designed to help astronomers weigh supermassive black holes in distant galaxies.”

“The combination of Hubble’s sharp-eyed observations and data from ground-based telescopes allowed astronomers to make detailed models of the mass of stars in these galaxies, which in turn helps constrain the mass of supermassive black holes.”
