A Hubble Space Telescope image of the supergiant elliptical galaxy ESO 306-17. Supergiant elliptical galaxies are some of the largest galaxies known. The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970 .
The galaxy has a very large halo of much lower intensity "diffuse light" extending to a radius of 600 kpc (2 million ly). [30] [verification needed] The authors of the study identifying the halo conclude that IC 1101 is "possibly one of the largest and most luminous galaxies in the universe". This view has been stated in several other papers as ...
This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension. This list refers only to coupling of matter with defined limits, and not the coupling of matter in general (such as, for example, the cosmic microwave background, which fills the entire universe). All ...
The galaxy is to be found approximately 10° northwest of Alpha Ursae Majoris (Dubhe) along with several other galaxies in the Messier 81 Group. [ 7 ] [ 11 ] Its apparent magnitude due to its distance means it requires a good night sky and only rises very briefly and extremely low at its southernmost limit from Earth's surface, about the 20th ...
This was announced as the most distant galaxy merger ever discovered. It is expected that this proto-cluster of galaxies will merge to form a brightest cluster galaxy, and become the core of a larger galaxy cluster. [148] [149] Galaxy protocluster SPT2349-56: z=4.3 (14 galaxies) This protocluster is located at 12.4 billion light years from the ...
[5] [6] As an elliptical galaxy, the galaxy is a spheroid rather than a flattened disc, accounting for the substantially larger mass of M87. Within a radius of 32 kiloparsecs (100,000 light-years), the mass is (2.4 ± 0.6) × 10 12 times the mass of the Sun, [ 47 ] which is double the mass of the Milky Way galaxy. [ 53 ]
The cosmic web — ribbons of gas and dust tying galaxies together — are the largest structures in the Universe, and a new study shows they are growing hotter over time.. Utilizing a phenomenon ...
Second brightest star in the night sky. Gacrux (γ Crucis) 73 [93] L/T eff: Twenty-sixth brightest star in the night sky. Polaris (α Ursae Minoris) 46.27 ± 0.42 [94] AD The current star in the North Pole. It is a Classical Cepheid variable, and the brightest example of its class. Aldebaran (α Tauri) 45.1 ± 0.1 [95] AD Fourteenth brightest ...
