We know the universe is and always was expanding, but we’ve never really known just how fast it’s happening. That is, until now. Researchers have used gravitational lensing to and watched a star die 5 ...

In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding? Astronomers have tried two main methods to figure it out, but their numbers don’t ...

In this mosaic image stretching 340 light-years across, Webb’s Near-Infrared Camera (NIRCam) displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of ...

A new study published in the Journal of Cosmology and Astroparticle Physics proposes an alternative model which gives the universe an expiration date. According to this new model, everything will come ...

IT IS ONE of the biggest mysteries in cosmology—and getting bigger all the time. Ever since Edwin Hubble, an American astronomer, published observations of distant galaxies in 1929, scientists have ...

If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. Space is big, and ...

On 1 January 1925, US astronomer Henry Norris Russell made a startling announcement to the American Astronomical Society in Washington DC: observations by fellow astronomer Edwin Hubble showed that ...

A more precise distance to the Coma galaxy cluster was measured. This measurement increases the discrepancy between observed and predicted universe expansion rates. The discrepancy, called the Hubble ...
