Hubble Views a Dim but Distinct Galaxy

UGC 11105 has an apparent magnitude, or brightness, of around 13.6 in the light our eyes are sensitive to, called visible or optical light. However, this image also holds ultraviolet data, allowing us to see wavelengths beyond those that the human eye can see. Because of its proximity and our perspective here on Earth, the Sun appears to be about 14 thousand trillion times brighter than UGC 11105, even though UGC 11105 is an entire galaxy. Hubble’s sensitivity and location above Earth’s light-distorting atmosphere allows the observatory to see extraordinarily dim objects in visible light, ultraviolet light, and a small portion of infrared light.
