A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers.
Using the James Webb Space Telescope, an international team of astronomers led by the University of Cambridge have spotted a 'dead' galaxy when the universe was just 700 million years old, the oldest such galaxy ever...

Vera Rubin’s research forced cosmologists to radically reimagine the cosmos.
In the 1960s and ’70s, Rubin’s observations of stars whirling around within galaxies revealed the gravitational...
Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research...
Like a celestial beacon, distant quasars make the brightest light in the universe. They emit more light than our entire Milky Way galaxy. The light comes from matter ripped apart as it is swallowed...
