Webb's First Deep Field is the first full false-color image from the JWST, [12] and the highest-resolution infrared view of the universe yet captured. [11] The image reveals thousands of galaxies in a tiny sliver of the universe, with Webb's sharp near-infrared view bringing out faint structures in extremely distant galaxies, offering the most ...
The Hubble Ultra-Deep Field (HUDF) is a deep-field image of a small region of space in the constellation Fornax, containing an estimated 10,000 galaxies.The original data for the image was collected by the Hubble Space Telescope from September 2003 to January 2004 and the first version of the image was released on March 9, 2004.

The discovery (by chance in 1965) of the cosmic background radiation suggests that the early universe was dominated by a radiation field, a field of extremely high temperature and pressure. [ 1 ] The Sunyaev–Zel'dovich effect shows the phenomena of radiant cosmic background radiation interacting with " electron " clouds distorting the ...
Assuming the universe keeps expanding and it does not suffer a Big Crunch, a Big Rip, or another similar fate, the cosmic microwave background will continue redshifting until it will no longer be detectable, [112] and will be superseded first by the one produced by starlight, and perhaps, later by the background radiation fields of processes ...
Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, [7] having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
The cosmic neutrino background (CNB or C ν B [a]) is the universe's background particle radiation composed of neutrinos.They are sometimes known as relic neutrinos.. The C ν B is a relic of the Big Bang; while the cosmic microwave background radiation (CMB) dates from when the universe was 379,000 years old, the C ν B decoupled (separated) from matter when the universe was just one second old.
"Late universe" measurements using calibrated distance ladder techniques have converged on a value of approximately 73 (km/s)/Mpc. Since 2000, "early universe" techniques based on measurements of the cosmic microwave background have become available, and these agree on a value near 67.7 (km/s)/Mpc. [64] (This accounts for the change in the ...
In the baryonic material of the Universe there are two sources of large amounts of energy: nuclear fusion and gravitation. Nuclear fusion takes place inside the stars, and we can really see this light redshifted: this is the main source of the cosmic ultraviolet- and visual background .
