Astronomers have observed a so-called standard candle supernova generating clouds of cosmic dust, bringing us a step closer to understanding the life and death cycle of stars.
Astronomers may finally know why some death shrouds created by the deaths of sun-like stars lack the element sulfur.
The James Webb Space Telescope could target tiny and bright galaxies in the early universe to unveil some secrets about the universe's most mysterious stuff, dark matter.
"The scientific breadth and impact of the survey is quite overwhelming; it’s hard to put into a few words."
Scientists want to know how galaxies get ensnared in the universe's 'cosmic web' and how this network of filamentary gas and dust drives galactic evolution.
Stars around the outskirts of our galaxy may hint at a secret about the Milky Way's dark matter.
The "peculiar," twisted galactic disk of the "trainwreck" lenticular galaxy NGC 4753 offers evidence of its violent collision with a dwarf galaxy over 1 billion years ago.
The motions of satellites in galaxy groups tell us that such groupings, and therefore possibly the universe, are younger than what standard cosmology tells us.
