This makes it the coldest place in the Universe found so far, besides laboratory-created temperatures. Even the 2.7 K background glow from the Big Bang is warmer than the nebula. It is the only naturally occurring object found so far that has a temperature lower than the background radiation. [6]
Messier 63 or M63, also known as NGC 5055 or the seldom-used Sunflower Galaxy, [6] is a spiral galaxy in the northern constellation of Canes Venatici with approximately 400 billion stars. [7] M63 was first discovered by the French astronomer Pierre Méchain , then later verified by his colleague Charles Messier on 14 June 1779. [ 6 ]
MACS J0416.1-2403 or MACS0416 abbreviated, is a cluster of galaxies at a redshift of z=0.397 with a mass 160 trillion times the mass of the Sun inside 200 kpc (650 kly).Its mass extends out to a radius of 950 kpc (3,100 kly) and was measured as 1.15 × 10 15 solar masses. [2]
New imagery has been released from NASA’s Hubble Space Telescope, which captured a photo of a spiral galaxy more than 76 million light-years away from Earth. The galaxy known to observers as NGC ...
Details of galactic dust and stars captured by telescope offer a picture to astronomers of the early universe

Least massive galaxy Segue 2 ~550,000 M Sun: This is not considered a star cluster, as it is held together by the gravitational effects of dark matter rather than just the mutual attraction of the constituent stars, gas and black holes.

A 2017 paper suggests that IC 1101 has the largest core size of any galaxy with a core radius of around 4.2 ± 0.1 kpc (13.70 ± 0.33 thousand ly) by fitting a model to a Hubble Space Telescope (HST) image of the galaxy.
