GN-z11 is a high-redshift galaxy found in the constellation Ursa Major.It is among the farthest known galaxies from Earth ever discovered. [5] [6] The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center).
Scientists studying the earliest black holes may have found an answer to dark matter, putting Stephen Hawking’s theory on the subject back into the spotlight. Scientists may have found an answer ...
Dark matter is called ‘dark’ because it’s invisible to us and does not measurably interact with anything other than gravity. It could be interspersed between the atoms that make up the Earth ...
The categories of dark matter are set with respect to the size of a protogalaxy (an object that later evolves into a dwarf galaxy): dark matter particles are classified as cold, warm, or hot if their FSL is much smaller (cold), similar to (warm), or much larger (hot) than a protogalaxy.
It possesses a diffuse core which is the largest known core of any galaxy to date, [5] and contains a supermassive black hole, one of the largest discovered. [5] IC 1101 is located at 354.0 megaparsecs (1.15 billion light-years) from Earth. It was discovered on 19 June 1790, by the German-British astronomer William Herschel. [6]
In April 2023, a study investigated four extremely redshifted objects discovered by the James Webb Space Telescope. [5] Their study suggested that three of these four, namely JADES-GS-z13-0, JADES-GS-z12-0, and JADES-GS-z11-0, are consistent with being point sources, and further suggested that the only point sources which could exist in this time and be bright enough to be observed at these ...
It has the largest system of gravitational arcs ever found. [5] Abell 1689 shows over 160,000 globular clusters, the largest population ever found. [6] There is evidence of merging and gases in excess of 100 million degrees. [5] The very large mass of this cluster makes it useful for the study of dark matter and gravitational lensing. [7] [8]
For years, science has assumed galaxies and dark matter go hand in hand. Now, a galaxy has been discovered that's almost completely devoid of it. This galaxy without dark matter is bending the ...
