A massive, rotating disk galaxy designated DLA0817g and nicknamed the "Wolfe Disk," formed just 1.5 billion years after the ...

Space observatories tend to work quietly, collecting data long before images reach the public. In March 2025, NASA launched the SPHEREx space telescop.

An international team of astronomers has performed multi-wavelength observations of the nearby Araish galaxy to investigate the origin of its radio emission. As a result, they detected an extended ...

Astronomers have puzzled for decades over how massive elliptical galaxies appeared so early in cosmic history. The standard ...

Long strands of glowing gas stretch behind a distant galaxy, dotted with pockets of newborn stars. The shape looks almost biological, like tentacles drifting through water. Yet this structure formed ...

Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing ...

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

How space telescopes capture distant galaxies using infrared imaging, precision optics, and astronomy technology beyond Earth's atmosphere.

He came up with a new one, called the Late-Transition Interacting Thawer (LTIT) model, which models how dark energy could "thaw" after a certain amount of time after the universe started and is slowly ...

Physicist Sean Carroll explains how physics, astronomy, philosophy, and classics all help us understand the expanding ...

Webb telescope data confirm a supermassive black hole fleeing its galaxy, carving a 200,000 light-year wake of new stars.

A massive star in the nearby Andromeda galaxy has simply disappeared. Some astronomers believe that it's collapsed in on ...
