It's 7 billion years ago, and the universe's heyday of star formation is beginning to slow. What might our Milky Way galaxy have looked like at that time? Astronomers have found clues in the form of a ...

Space is full of punctuation. Look carefully, and you'll see periods, colons, ellipses, even commas. Complex symbols are slightly more elusive, but the JWST has just spotted one in the wild. There, in ...

When the James Webb Space Telescope (JWST) captured a recent image of two baby stars forming in a nearby system, scientists weren’t expecting anything out of the ordinary. But tucked away in the ...

The galaxy cluster MACS-J0417.5-1154 is so massive it is warping the fabric of space-time and distorting the appearance of galaxies behind it, an effect known as gravitational lensing. This natural ...

Astronomers using the James Webb Space Telescope have discovered a pair of distant galaxies being twisted into a cosmic question mark thanks to a rare form of gravitational lensing. When you purchase ...

Space scientists have pictured a 'cosmic question mark'. Astronomers using NASA’s James Webb Space Telescope say the observation of a distant galaxy cluster offers clues about how stars are formed.

Clusters of galaxies are the largest structures in the Universe that are held together by gravity. Because of their immense size and mass, galaxy clusters are extremely useful as tools to probe a ...
