Astronomers may have found the long-missing half of the universe's regular matter—and it appears to have been right under our ...

Astronomers tallying up all the normal matter—stars, galaxies and gas—in the universe today have come up embarrassingly short ...

The Case of the Missing Matter "We robustly show that the gas is much more extended than the dark matter" relative to ...

For decades, scientists have known that ordinary matter — everything made of atoms — accounts for just 15% of the universe’s ...

Astronomers have known for many decades that the universe is expanding; in the 1990s, the first image of the cosmic microwave background ... higher rate around 7 billion years ago," said Arnaud ...

It wasn’t until approximately 380,000 years after the Big Bang that the universe cooled enough for light to escape, leaving behind an imprint known as the Cosmic Microwave Background (CMB).

This has given scientists their best look yet at the Cosmic Microwave Background (CMB) - the leftover radiation from the Big Bang which fills the entire observable universe. What looks like clouds ...

The map shows the cosmic microwave background (CMB), a faint remnant radiation from the early stages of the universe. It began as the earliest light just 380,000 years after the big bang ...

The cooled remnant of the first light that permeated the universe is known as the cosmic microwave background—leftover radiation from the Big Bang that can still be detected in the distant universe.

A telescope in Chile has spent years working on by far the most precise map of the earliest visible universe. It now reveals a lot about the cosmos. An international research group has created the ...

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.

Scientists believe that the continuous microwave background radiation is the remains of the heat energy from the Big Bang, spread thinly across the whole Universe. Heat energy left over from the ...
