Webb Spots Possible Red Supergiant Star in Early Universe

Nov 2, 2022 by Natali Anderson

Nicknamed Quyllur, the newly-detected red supergiant candidate is so far away that its light has taken 10.7 billion years to reach Earth. This Webb image...

This image from the NASA/ESA Hubble Space Telescope shows ACT-CLJ0102-4915. Massive galaxy clusters such as ACT-CLJ0102-4915 are useful tools for studying very distant objects, because this lens-like behavior amplifies the light from faraway galaxies in the background. They also contribute to a range of topics in cosmology, as the precise nature of the lensed images encapsulates information about the properties of spacetime, the expansion of the cosmos and the distribution of dark matter within the cluster.
