A feeding black hole at the heart of a nearby galaxy is behaving similarly to cosmic titans that existed just after the Big Bang.
The universe is haunted by "cosmic ghosts" called neutrinos, which seem to be the "whispers" of stars that died in supernova explosions over the course of billions of years.
Using the ESA's Euclid space telescope, astronomers have discovered a treasure trove of black hole-powered quasars in the early universe, including the most ancient and distant ever seen.
When some stars die, they do not do so alone, potentially solving a long-standing mystery around a particular class of cosmic explosion called an interacting supernova.
To celebrate the fourth birthday of the James Webb Space Telescope, NASA has released a stunning image of the strangely shaped galaxy Centaurus A, the site of a cosmic collision 2 billion years ago.
NASA's exoplanet-hunting spacecraft TESS has a new method for detecting worlds beyond the solar system, and it is thanks to Einstein.
Mysterious "little red dots" discovered in the early universe by the James Webb Space Telescope could harbor buried black holes that fire high-energy neutrinos through the cosmos.
Celebrating America's 250th birthday, Space.com looks back at what our understanding of space was like in 1776 and what major developments occurred to change our thinking.
Infant stars celebrate their independence with cosmic fireworks in a stunning new image from the James Webb Space Telescope.
"It's like using a time machine to peer into the distant future of our solar system."
Astronomers have discovered a curious new exoplanet that challenges assumptions about hot Jupiters, some of the most extreme planets in the universe.
"With the launch of the ten-year Legacy Survey of Space and Time, the Rubin Observatory is opening a new window on the universe."
Using the James Webb Space Telescope, astronomers have spotted a massive and densely packed galaxy cluster at "cosmic noon" before such structures were thought to be possible.
The loudest crash of gravitational waves ever heard provides an intriguing way of studying event horizons, the boundaries at which nothing can escape the grip of these cosmic titans.
Astronomers have discovered two "super-puff" exoplanets orbiting the same star that have densities lower than cotton candy, making them the lightest worlds ever seen.
The ESA's dark universe detective spacecraft Euclid, has studied the heart of the Milky Way, creating the largest and most detailed photo of this region ever made.
"This discovery provides a crucial insight into how planets form even around massive, eccentric objects."
The expansion of the universe is still accelerating under the influence of dark energy, despite recent claims to the contrary averting a cosmological crisis, according to new research.
Scientists have discovered that dying stars don't go down without a fight, with red giants spitting out blobs of plasma and receiving a corresponding "kick."
The Orion A region has never looked as colorful and vibrant.
New research has failed to rule out self-annihilating dark matter as the source of a hotly debated gamma-ray emission known as the Galactic Center Excess radiating from the heart of the Milky Way.
A technique called echo mapping suggests supermassive black holes, like that at the heart of the Milky Way, are surrounded by clusters of dark matter.
"If confirmed, Shadow Blaster would be the first-ever individual dusty star-forming galaxy directly linked to a high-energy neutrino event."
