A new method could improve cosmology research by analyzing supernovae together with the galaxies that host them.

You’d think that supernovae – the death throes of massive stars and among the brightest, most powerful explosions in the universe – would be hard to miss. Yet the number of these blasts observed in ...

Across the sky, astronomers are stitching together vast samples of galaxies to understand how often supermassive black holes flare, feed, and reshape their surroundings. The headline image of an ...

Image of the Kinman Dwarf galaxy taken with the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 in 2011, before the disappearance of the massive star. (NASA, ESA / Hubble, J. Andrews, University ...

James Webb was built to look through cosmic dust and back toward the first galaxies, but its latest findings are doing more ...

An international team of astronomers has identified three ultra-massive galaxies—each nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang. The ...

JWST observations show that early galaxies were chaotic, gas-filled systems rather than stable disks. Researchers from Cambridge studied over 250 galaxies and found most were turbulent, still forming ...

One of the most puzzling findings from the JWST's observations of the early universe is the size of black holes. According to ...

The James Webb Space Telescope caught a glimpse of these violent bundles of gas and stars. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The ...

Using the James Webb Space Telescope, scientists spotted thin and thick disks in galaxies as far back as 10 billion years ago—something never seen before. These observations reveal that galaxies first ...
