Astronomers using the James Webb Space Telescope have spotted something that shouldn’t exist—at least not so early in the ...
Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory puts that timeline at roughly 5 to 10 billion years in galaxies. Yet ...
The James Webb Space Telescope (JWST) has revealed a slow-rotating galaxy, XMM-VID1-2075, from the early universe, ...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope have looked deeply at thousands of young star clusters in four nearby galaxies, studying ...
Supermassive black holes lurk at the centers of massive galaxies, including our own Milky Way. Puzzlingly, supermassive black ...
Early galaxies were star-forming machines, furiously gobbling up gas and spitting out stars. A new model helps explain why ...
The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. It was 2018, and the discovery had just been announced. A team ...
If you’ve ever been to a place with minimal light pollution and looked skywards at nighttime, you’ve probably seen our Milky Way galaxy. It manifests as a thick, hazy band of stars streaking across ...
