California-based startup Reflect Orbital aims to build a swarm of 4,000 giant mirrors in low Earth orbit to "sell sunlight" ...

Astronomers have captured the glowing "wings" of a vast nebula shaped like a bat, unfurling in deep space about 10,000 ...

Astronomers have captured a haunting image of a “cosmic bat” spreading its wings across deep space. This nebula, 10,000 light-years away, glows crimson as newborn stars ignite clouds of gas and dust.

The gas giant WASP-18b belongs to a class known as ultra-hot Jupiters — giant, searing, gaseous planets that orbit perilously close to their stars. Researchers used a new technique called ...

The space object, named Chiron, is believed to be a piece of rock measuring a whopping 130 miles wide at its broadest point - ...

The James Webb Space Telescope has looked back into deep time to find “rubies” or “little red dots” stretched across the universe.

About 50 light-years from Earth, a gas giant about half the mass of Jupiter orbits a sunlike star. The discovery of Pegasi 51 b ushered in a new era of exoplanet research.

Astronomers are hustling to use interplanetary spacecraft to study the interstellar comet dubbed 3I/ATLAS while the sun is ...

The comet is on what’s known as a hyperbolic trajectory, which means that it doesn’t follow an orbital path around the sun.

Astronomers observe Type II supernova SN 2024bch behaving differently, with energy from Bowen fluorescence rather than ejecta interaction, challenging models of stellar death and high-energy neutrino ...

Astronomers have unveiled the largest low-frequency radio color image of the Milky Way ever created, offering a sprawling, ...

An interstellar comet that originated outside our solar system has just made its closest pass to the sun, brightening ...
