The revolutionary James Webb Space Telescope and next-gen radio telescopes are probing what’s known as the epoch of ...

According to a tenet scientists call the cosmological principle, our place in space is in no way exceptional. But recent ...

Independent methods measuring the expansion rate of the universe do not agree on its value. This is known as the Hubble ...

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 ...

"I never dreamed of Webb seeing them in such large numbers." ...

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).

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 ...

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 this model, dark matter and dark energy are crucial to explaining the structure of the universe on the largest scales. But the model also has to account for the cosmic microwave background and ...

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 ...
