Cosmology Grid List Latest about Cosmology What is the speed of light? By Briley Lewis published 30 May 23 Light is faster than anything else in the known universe, though its speed can change depending on what it's passing through. What's the difference between outer space and deep space? By Briley Lewis published 24 May 23 Space, outer space, and deep space — which is further out, and which is the real final frontier? James Webb Telescope finds evidence of 'celestial monster' stars the size of 10,000 suns lurking at the dawn of time By Ben Turner published 19 May 23 The James Webb Space Telescope has found key chemical fingerprints of supermassive stars just 440 million years after the Big Bang. Scientists watched a 'reappearing supernova' explode 5 times in a row — and it could help reveal how fast the universe is expanding By Isobel Whitcomb published 18 May 23 After showing up five times in Hubble images, a 'reappearing supernova' is helping scientists solve one of astronomy's biggest mysteries. Scientists discover secret 'symmetries' that protect Earth from the chaos of space By Anna Demming published 9 May 23 A new analysis of chaos in the solar system reveals how planetary collisions are avoided over billions of years. Astronomers find remnants of the oldest stars in the universe By Joanna Thompson published 8 May 23 A gas cloud 13 billion light-years away may be the resting place of some of the earliest stars in the universe. 'Green Monster' supernova is the youngest in the Milky Way, James Webb telescope reveals By Stephanie Pappas published 12 April 23 New James Webb Space Telescope images reveal the grisly past of Cassiopeia A, the youngest known supernova remnant in the Milky Way. Bizarre object 10 million times brighter than the sun defies physics, NASA says By Briley Lewis published 11 April 23 A bizarre 'ultraluminous X-ray source' shines millions of times brighter than the sun, breaking a physical law called the Eddington limit, a new study finds. Strange radio bursts that outshine entire galaxies may come from colliding neutron stars, new study suggests By Robert Lea published 6 April 23 Powerful bursts of radiation called fast radio bursts could be launched when neutron stars collide and merge, gravitational wave detections indicate. James Webb telescope discovers the 4 oldest galaxies in the universe, born just 300 million years after the Big Bang By Briley Lewis published 6 April 23 Astronomers using the James Webb Space Telescope have detected the four oldest galaxies in the known universe, which are forming stars much faster than thought possible. 123456789Archives Live Science newsletter Stay up to date on the latest science news by signing up for our Essentials newsletter.
