A new AI-powered framework could transform how astronomers measure the expansion of the Universe. By analyzing images of Type Ia supernovae and modeling their environments in unprecedented detail, ...

For decades, physicists have searched for one of the faintest signals in the cosmos: a background of neutrinos released by ...

Researchers confirm the universe's expansion is still accelerating, challenging previous claims of dark energy weakening and halting this growth.

The expansion of the universe is still accelerating under the influence of dark energy, despite recent claims to the contrary.

In recent years, whenever astronomers have gazed into the night sky, they’ve noticed something peculiar: Some of its massive stars—the true titans of the cosmos—appear to be missing. The largest of ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new Type II supernova. The newly detected supernova, named SN Eos, exploded when the universe was ...

A unified solution: Comprehensive models The new study tackles this problem by modeling everything at once: supernova explosions, the galaxies that host them, the dust that dims and reddens their ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

The James Webb Space Telescope is weighing in on a longstanding debate over why we don’t see more of the most massive red supergiant stars go supernova. NASA/ESA/CSA/Northrop Grumman In recent years, ...
