New Indian telescope identifies its first supernova
A newly built International Liquid Mirror Telescope (ILMT) in India has identified its first supernova—designated SN 2023af. The finding, reported November 8 on the pre-print server arXiv, proves that ILMT may be capable ...
Hubble sets sights on an explosive galaxy
When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and intensely luminous—so ...

Heavier stars might not explode as supernovae, just quietly implode into black holes
A supernova is a brilliant end to a giant star. For a brief moment of cosmic time, a star makes one last effort to keep shining, only to fade and collapse on itself. The end result is either a neutron star or a stellar-mass ...

Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova
A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers ...

Even if we can't see the first stars, we could detect their impact on the first galaxies
For a long time, our understanding of the universe's first galaxies leaned heavily on theory. The light from that age only reached us after traveling for billions of years, and on the way, it was obscured and stretched into ...
