This model is from the ESA's Planck mission to study the cosmic microwave background. After the Big Bang, for the first 380,000 years or so, the universe was so hot and dense that it was ...

This Cosmic Microwave Background Radiation (CMBR ... This radiation is now used to 'map' the early Universe. The diagram below is a heat map showing that temperature was not evenly distributed.

In 1927 Georges Lemaître proposed that the Universe began with an explosion called the Big Bang. Hubble’s research into the red shift of galaxy light showed that the Universe was expanding ...

The universe is a turbulent place ... We can, however, gather indirect evidence of the cosmic background of gravitational waves. Last year, the North American Nanohertz Observatory for ...

In 2020 Nobel Laureate Sir Roger Penrose claimed that an earlier universe existed before the Big Bang and can still be observed today as a scar on the cosmic microwave background (CMB).

Galanti and his colleagues had previously found evidence of axion-like particles in light from distant blazars – extremely active galaxies that blaze with light. But the brightest gamma-ray explosion ...

Distances to objects in the universe are measured indirectly and take advantage of the parallax effect. When an object is being measured against a stationary background, it appears to move when ...

Cosmic microwave background (CMB) fluctuations ... According to Turok, quantum uncertainty ensures that the Universe and anti-universe are not perfectly symmetrical, resolving philosophical ...

In contrast, theoretical models based on the cosmic microwave background predict an expansion ... "The discrepancy suggests our understanding of the universe may be incomplete," said Nobel ...
