The latest Swedish-led search for technosignatures in the form of Dyson spheres has again come up empty-handed. The two latest stellar candidates in the hunt for such hypothetical extraterrestrial technology have been eliminated as Dyson spheres.

Using the James Webb Space Telescope, astronomers have studied 72 young sun-like stars to discover that forming planets is a real race against time.

A new James Webb telescope study suggests the universe's enigmatic "little red dots" may not have vanished after all — they may simply look different as we observe them across cosmic time.

The James Webb Space Telescope, the most powerful observatory ever launched, orbits the Sun about a million miles from Earth, far beyond the reach of any current spacecraft carrying astronauts. That distance is not an accident or an inconvenience to be worked around;

James Webb Space Telescope is finding that between the brightest stars, the cosmic skyscrapers, there are much fainter stars, meaning early galaxies are more massive than we believed.

Hubble has been collecting data for 35 years, and the total sits at roughly 400 terabytes. NASA's next great observatory could produce 500 terabytes in a single

While NASA’s Hubble Space Telescope is known for its sharp observations in ultraviolet, visible and near-infrared light, and the James Webb Space Telescope primarily observes the universe in infrared, Roman is designed to survey much larger areas of the sky while maintaining Hubble-like image quality.

Light from a distant galaxy has travelled for more than 12.5 billion years to reach Earth, allowing astronomers to see the universe when it was only about 1.2 billion years old. At that remarkable stage in cosmic history,
