Astronomers using the James Webb Space Telescope have detected the oldest "dead" galaxy ever observed, at just 700 million years after the Big Bang. The stalled-out relic defies explanation by our current knowledge of the early cosmos.

More than 50 years after the Apollo era, major governments and well-funded private companies still struggle with lunar landing missions. Why is landing on the moon so hard in 2024?

A group of extremely bright stars may be slowly reshaping the Orion Nebula and stopping one of their neighbors from forming planets, new James Webb Space Telescope observations suggest.

A distant star system housing 6 planets that move in 'mathematically perfect' orbits has ignited a search for possible alien technosignatures.

A green "Grinch-like" shape in a supernova remnant imaged by the James Webb telescope may have come from a blast debris field, scientists proposed

Ambitious new missions to the moon, Venus, Jupiter and more are planned for 2024. Here is a preview of the exciting year in space ahead.

An analysis of 42 ancient stars in the Milky Way reveals the first hints of nuclear fission in the cosmos, hinting at the existence of elements far heavier than anything found naturally on Earth.

Scientists found signs of organic molecules in the first samples of potentially hazardous asteroid Bennu, as well as a 'head scratching' material that has yet to be identified.

The early galaxy AzTECC71 is so far away it keeps disappearing from telescope observations. A new study by the James Webb Space Telescope finally pins it down.

Hydrogen detected in Apollo-era moon rocks suggests that future astronauts could harvest water available right on the moon to use as rocket propellant and for life support.

New research finds that certain large exoplanets are shrinking due to internal processes, creating an abundance of rocky 'super-Earths'.

A Milky Way doppleganger discovered in the early universe suggests some key physical ingredient is missing from cosmological models.

Scientists made a twin version of our universe, showing the evolution of all forms of matter and energy, in the biggest cosmological computer simulation to date.

Contrary to conventional wisdom, a pair of black holes could exist in perfect pairs without leading to a cataclysmic merger, new research suggests. All it takes is a dose of cosmic expansion.

The strongest recorded Marsquake, which rattled for six hours in May 2022, left no visible traces on the Red Planet surface. Now, scientists think they know what caused it.

Naturally occurring superheavy elements beyond those listed in the periodic table could potentially explain why asteroid 33 Polyhymnia is so dense, new research suggests.

New research showing that elusive antimatter falls downward toward the Earth proves Albert Einstein right yet again.

Bright flashes in the clouds of Venus once thought to be lightning strikes may have a cosmic origin.

Half a century after the first humans landed on the moon, global interest is once again rising to visit our celestial neighbor. This time, nations have their sights set on the lunar south pole. Why?

The six-wheeled Pragyan rover just notched another milestone while exploring the lunar south pole.

The Aditya-1 solar mission launches hot on the heels of India's first moon landing.

India landed its Chandrayaan-3 spacecraft near the moon's south pole today (Aug. 23), making history for the nation and for lunar exploration in general.
