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 .
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 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 ...
Luminous red novae appear to expand extremely rapidly, reaching thousands to tens of thousands of solar radii within only a few months, significantly larger than the largest red supergiants. [ 2 ] Some studies use models that predict high-accreting Population III or Population I supermassive stars (SMSs) in the very early universe could have ...
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 ...
The following are a list of spacecraft with a mass greater than 8,000 kg (17,637 lb), or the top three to any other orbit including a planetary orbit, or the top three of a specific category of vehicle, or the heaviest vehicle from a specific nation. All numbers listed below for satellites use their mass at launch, if not otherwise stated.
Those groups and clusters and additional isolated galaxies in turn form even larger structures called superclusters. The Abell 901/902 supercluster is located a little over two billion light-years from Earth. [4] Their existence was first postulated by George Abell in his 1958 Abell catalogue of galaxy clusters. He called them "second-order ...
[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 ]
