Hace 22 horas · The cosmic microwave background ( CMB or CMBR) is microwave radiation that fills all space in the observable universe. It is a remnant that provides an important source of data on the primordial universe. [1] With a standard optical telescope, the background space between stars and galaxies is almost completely dark.
14 de may. de 2024 · Frank H. Shu. Cosmic microwave background (CMB), electromagnetic radiation filling the universe that is a residual effect of the big bang 13.8 billion years ago. Because the expanding universe has cooled since this primordial explosion, the background radiation is in the microwave region of the electromagnetic spectrum.
Hace 6 días · In radio astronomy, a fast radio burst (FRB) is a transient radio pulse of length ranging from a fraction of a millisecond, for an ultra-fast radio burst, to 3 seconds, caused by some high-energy astrophysical process not yet understood.
6 de may. de 2024 · Microwaves. Credit: NASA/JPL-Caltech. Microwaves are from about 1 millimeter (about the size of a sharp pencil point) to about 1 foot long. This window shows us the microwave energy known as the cosmic background radiation. It is the "noise" left from shortly after the Big Bang that began the universe billions of years ago.
26 de abr. de 2024 · It’s true: the cosmic microwave background (CMB) radiation, which we’ve concluded is the leftover glow from the Big Bang itself, is that key evidence. Here’s why it confirms the Big Bang,...
4 de may. de 2024 · The Cosmic Microwave Background (CMB) reveals the "quantum seeding" of the primordial universe, the minute fluctuations of radiation that the Big Bang spewed into an initially very small universe.
5 de may. de 2024 · 1 view 1 minute ago. Today, as Cosmic Radio just ended, and since there were over 1300 submissions, I think it's time to rank the best 50 songs! Of course, this is all personal opinion, but I...
