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

This is only the third interstellar comet scientists have observed. Its extreme brightening, unusual composition, and intense ...

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 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 - ...

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 ...

Despite it’s comparative size to our star, it’s still the least massive object ever detected using gravitational lensing.

Astronomers just caught a rare glimpse of an interstellar comet as it zoomed past Mars. Images of the object, dubbed 3I/ATLAS, were captured by two of the the European Space Agency's Mars orbiters -- ...

Another interesting consequence of relativity is that as time stretches out at high speeds, distances diminish. It’s hard to ...

More than a thousand years ago, astronomers from the Maya civilization developed one of the most sophisticated time-keeping ...
