Astronomers Devise a New Way to Measure Cosmic Expansion with Lensed Supernovae Researchers in Munich have used the Large Binocular Telescope in Arizona to capture five images of one and the same supernova in a single picture. The gravity of two foreground galaxies has deflected the light from a supernova far in the background along different paths to Earth.

How fast is the universe expanding? Supernova could provide the answer The image of an extremely rare supernova could solve the mystery of the expansion rate of the universe.

Munich astronomers imaged and modelled an exceptionally rare #supernova that could provide a new, independent way to measure how fast the #universe is expanding: go.tum.de/991366 🌌

New theory of universe expansion may upend way we look at cosmos A study has challenged the common conception that the universe’s expansion is accelerating, supporting the idea that reality could one day end in a ‘big crunch’

Great article in @thetimes.com by @rhysblakely.bsky.social about the Son et al. (2025) #MNRAS paper published by @royalastrosoc.bsky.social on supernova host-galaxy ages and the implications for #CosmicExpansion - is there now a real case for evolving #DarkEnergy?

Sounds impossible, but it's a real consequence of #CosmicExpansion. A new explainer breaks down how the universe's ultimate speed limit has a very important loophole: space itself.
