The cosmic microwave background (CMB) is radiation that fills the universe almost uniformly—basically the leftover glow from the early cosmos. It has an almost perfect blackbody spectrum at about 2.7 ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

A portable detector the size of a cookie box reveals in real time the cosmic particles that pass through your body every ...

Discover why astronomy and cosmology are the universe's mapmakers. Discover how scientists trace galaxies, the cosmic web, and the large-scale architecture of our entire existence in three dimensions ...

Examine the varied employment options available with a degree in cosmology. Graduates use advanced skills in mathematical ...

Mars is not just a colder, dustier version of Earth. It is a planet soaked in high‑energy particles that batter rock, metal, ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields from the Big Bang may offer a solution.

Ralph Asher Alpher (February 3, 1921 – August 12, 2007) was an American cosmologist who carried out pioneering work in the ...

Physicists suggest that a single, extraordinarily powerful cosmic signal detected on Earth could be linked to the explosive end of a tiny black hole from the early universe. That signal now stands as ...

Discover seven unusual galaxies defying scientific predictions, from impossibly bright early universe objects to astrophysics ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been ...
