The James Webb Space Telescope's detection of tellurium in the violent environment of a dead-star merger is a step toward determining where the universe's heaviest elements come from.

The NOAA satellites GOES-East and GOES-West watched as the shadow of the moon darkened the surface of Earth on Saturday, Oct. 14.

The European Space Agency's Gaia telescope revealed half a million newfound stars, and detailed the orbits of over 150,000 asteroids.

The European Space Agency's dark energy and dark matter spacecraft has once again found its guiding stars and is preparing for full "science mode."

Astronomers detected the dusty afterglow of a massive planetary collision in a star system 3,600 light-years away, where two giant icy worlds met their end.

The surprising detection of light 200 times more powerful than previous observations from the nearby pulsar Vela indicates hidden physics around dead stars.

Two conflicting methods to measure the expansion rate of the universe give different results, but researchers could resolve the disparity by watching merging neutron stars explode.

A team of astronomers has used a tricky technique to study an ancient galaxy previously lost in the glare of a blazing quasar.

Some of the moon's surface water may have an Earthly origin, due to high-energy interactions between the sun and Earth's magnetic shield, new research suggests.

Studying the mysterious form of matter around ancient quasar galaxies could have profound implications for our understanding of how the cosmos evolved.

"We aren’t going to see little green men but rather spectral signatures of these key chemicals, or what we call biosignatures."

Black holes can swallow matter, and they grow by accreting gas, dust and even the occasional star. But are they the vacuum-mouthed monsters they are often presented to be?

Is something fishy happening on the Red Planet, or is it all in our minds again?

Black hole sun, won't you come? It all depends on a star's mass before it dies.

Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same.

The use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab.

The discovery represents the first evidence that low-mass T.Tauri stars, which are less than 10 million years old, can emit gamma radiation.

So-called 'picojets' spotted by ESA's Solar Orbiter could be feeding high-speed gas outflows from the sun in the form of both energy and matter.

Scientists are still in the dark about what is causing a huge shadowy patch to appear against the blue background of Neptune’s sky.

Also known as "failed stars," brown dwarfs are celestial bodies that sit on the boundary between gas giant planets and tiny stars.

The puzzle of how supermassive black holes grew so large just after the Big Bang could soon be solved.

A century-old mystery of how galaxies change shapes has been solved by considering 'survival of the fittest' collisions between cosmic titans.

Astronomers have found planets that are twice as wide as Jupiter and more than 10 times as heavy, but there's a limit to how big planets can get.

The sun's corona is 200 times hotter than its surface, defying models of stellar bodies. Now, this 80-year-old puzzle may finally have a solution.

Superfast changes to the intensity of a jet blasting out from a small black hole have been detected for the first time.
