Early Universe:Neutron StarsNeutron Stars:Early UniverseIt is known that most part of neutron stars consist of supernovae remnants and that also a small part of them can be made from white dwarfs that, with suitable accretion conditions, overcame the Chandrashekar limit becoming neutron stars. ...
During the first 500 million years of cosmic history, the first stars and galaxies formed, seeding the Universe with heavy elements and eventually reionizing the intergalactic medium1,2,3. Observations with the James Webb Space Telescope (JWST) have uncovered a surprisingly high abundance of candida...
The extreme astrophysical processes and conditions that characterize the early Universe are expected to result in young galaxies that are dynamically different from those observed today1–5. This is because the strong effects associated with galaxy merge

The Aftermath of a Neutron Star Collision Resembles the Conditions in the Early Universe Neutron stars are extraordinarily dense objects, the densest in the Universe. They pack a lot of matter into a small space and can squeeze several solar masses into a radius of 20 km.Whe...
Two teams of astronomers led by researchers at the University of Cambridge have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars - extremely luminous objects powered by supermassive
WASHINGTON, Oct. 17 (Xinhua) -- Italian and American astronomers discovered a large structure in the early Universe, formed just two billion years after the Big Bang, according to a study published on Wednesday in the journal Astronomy & Astrophysics. ...
New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early Universe took place sooner than previously thought. A European team of astronomers have found no evidence of the first generation of s
