The Hubble Space Telescope photographed spiral galaxy UGC 11105 in the constellation Hercules.
This was reported by the ESA observatory, according to Ukrinform’s report.
UGC 11105 itself is located almost 110 million light-years from Earth.
It is stated that the apparent magnitude of the spiral galaxy in the optical light regime is approximately 13.6, while the Sun’s apparent magnitude is approximately 26.8.

This means that even though UGC 11105 is an entire galaxy, from the perspective of a person on Earth the Sun appears approximately 14 thousand trillion times brighter than UGC 11105.
The faintest stars visible to the naked eye have an apparent magnitude of 6, and most galaxies are much fainter than that.
However, Hubble is known to detect objects up to an extraordinary apparent magnitude of 31, so observing UGC 11105 should not pose much of a problem for it.
Apparent magnitude is a dimensionless quantity that characterizes the brightness of a celestial body (the amount of light coming from it) from the point of view of an earthly observer.
As reported by Ukrinform, the Hubble space telescope took a photo of the spiral galaxy IC 438 located in the constellation Hare.
