NASA’s Roman Space Telescope will launch with cutting‑edge science and over 1.35 million names hitching a ride to deep space. NASA’s upcoming launch of the Nancy Grace Roman Space Telescope will carry not only cutting‑edge instruments but also a...

James Webb spots three actively feeding supermassive black holes in a galaxy just 1.2 billion years after the Big Bang. An international team led by the Max Planck Institute for Extraterrestrial Physics has used the James Webb Space Telescope to reveal...

Astronomers have long struggled to explain how such gargantuan objects appeared just a few hundred million years after the Big Bang. Evidence from these ancient mergers could reveal whether these black holes grew from “large seeds” or through a rapid...

stars, primordial black holes are theorized to have formed within the high-density fluctuations present shortly after the Big Bang. Because these objects emerged during extreme cosmic phase transitions, they represent a unique archive of the Universe’s...

provide the best platform to investigate complex questions like matter formation, short of having witnessed the Big Bang itself.” The successful modeling of these dynamics suggests that quantum simulators will play an increasingly vital role in mapping...

The resulting observations identified the earliest supernova ever detected, dating back to 730 million years after the Big Bang. Perhaps most surprising to researchers, such as University College Dublin’s Antonio Martin-Carrillo, was the striking...

differ significantly from the stellar-mass black holes created by collapsing stars today. If they formed shortly after the Big Bang, they would have emerged from regions of intense density. The researchers examined three primary formation...

of Reionization A primary goal of the Lumina project is to chart the period known as cosmic reionization. Following the Big Bang, the universe was filled with neutral hydrogen gas. As the first stars and galaxies ignited, their energetic output stripped...

The James Webb Space Telescope has uncovered unexpected secrets of the early Universe, challenging our understanding of how the cosmos first took shape. The James Webb Space Telescope (JWST) has identified four distinct pairs of mysterious cosmic...

Scientists are using lunar lasers and binary pulsars to transform familiar astronomical systems into powerful detectors for ancient gravitational waves. For billions of years, the Moon has traced a steady path around Earth. Now, physicists suggest this...

Astronomers have traced a fleeting radio signal to a distant galaxy, unlocking a powerful new method to investigate the history of the early universe. Astronomers have captured a fleeting radio pulse that originated more than 10 billion years ago,...
