A dazzling galaxy discovered by the James Webb Space Telescope (JWST) is forcing cosmologists to reexamine key assumptions ...

Physicists had long assumed that the elusive force has constant strength. But the latest results from a project to map the ...

Historically, a hypothesis known as the 'tired light' theory suggested that light loses energy during its long cosmic journeys, leading to the redshift.

An international team has discovered a giant spiral disk galaxy in the early cosmos which is three times larger than similar ...

The resulting spectrum confirmed the redshift to be 13.0. This equates to a galaxy seen just 330 million years ... and ...

The same shifts in frequency and wavelength are also observed for light coming from stars in distant galaxies. By comparing the light from distant stars with the spectrum of light from our Sun it ...

Jon Chase explains the scale of the solar system and universe using simple demonstrations at a shopping centre and race track. He explains the Doppler effect and introduces red-shift and cosmic ...

A tiny red speck, spotted by the James Webb Space Telescope, has set a date on an important era in the Universe's history. The speck, known as JADES-GS-z13-1-LA, is one of the earliest galaxies ever ...

My research interests lie in theoretical astrophysics and UV/X-ray space astronomy. I work on theories of galaxy formation, reionization, first stars, primordial metal production, and numerical ...

In 1929 Edwin Hubble published the first solid evidence that the universe is expanding. Drawing upon data from Vesto Slipher and Henrietta Leavitt, Hubble demonstrated a correlation between ...
