NGC 4565 (also known as the Needle Galaxy or Caldwell 38) is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices. [2] It lies close to the North Galactic Pole and has a visual magnitude of approximately 10. It is known as the Needle Galaxy for its narrow profile. [4]
The location of NGC 5466 (circled in red) NGC 5466 imaged with a 32-inch telescope NGC 5466 is a class XII globular cluster in the constellation Boötes.Located 51,800 light years from Earth and 52,800 light years from the Galactic Center, it was discovered by William Herschel on May 17, 1784, as H VI.9.
It consisted of two known rich clusters and one newly discovered cluster as a result of the study that discovered it. The then known clusters were Cl 1604+4304 (z=0.897) and Cl 1604+4321 (z=0.924), which then known to have 21 and 42 known galaxies respectively. The then newly discovered cluster was located at 16 h 04 m 25.7 s, +43° 14′ 44.7 ...
A panorama of colliding galaxy clusters glimmers in a new image, captured by the combined forces of the two most powerful space observatories ever created. The cosmic phenomenon, called MACS0416 ...

By 1932, Shapley reported the discovery of 76,000 galaxies brighter than 18th apparent magnitude in a third of the southern sky, based on galaxy counts from his plates. Some of this data was later published as part of the Harvard galaxy counts, intended to map galactic obscuration and to find the space density of galaxies.
Galaxies and galaxy clusters < 50 M ly away from Earth plotted in the supergalactic plane. The supergalactic coordinate system is a reference frame for the supercluster of galaxies that contains the Milky Way galaxy, referenced to a local relatively flat collection of galaxy clusters used to define the supergalactic plane.
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]
