NASA's Chandra X-ray space telescope has spotted the cosmic serial killer that, like Michael Myers, is back for a sequel, killing a star and attacking a second star with its remains.

Astronomers using the James Webb Space Telescope had to race against time to image a young exoplanet before it disappeared for a decade.

'If we can understand how these materials came to be on Earth, it might give us clues to how life originated here, and how it might emerge elsewhere.'

Using the James Webb Space Telescope, astronomers have found a "first of its kind" world, an exoplanet that is twice the size of Earth and has an atmosphere packed with steam.

A powerful geomagnetic storm illuminated auroras that lit the skies over Earth on Thursday (Oct. 9) after X 2 solar flare that erupted from the sunspot AR 3848 on Tuesday (Oct. 8) evening.

NASA's Hubble Space Telescope and New Horizons Pluto probe have teamed up to image the ice giant Uranus, which will help inform future direct imaging of exoplanets.

There's too much antimatter in cosmic rays, showers of charged particles that pelt Earth. Could this be explained by annihilating dark matter? If so, does it point to the existence of WIMPs?

Using the Gaia space telescope, astronomers have observed 55 massive stars ejected from their home star cluster in the Large Magellanic Cloud at speeds equivalent to 80 times the speed of sound.

Astronomers have discovered the most distant and, thus, earliest strongly rotating galaxy ever seen that is well-organized rather than chaotic and messy, challenging our theories of cosmic evolution.

"Venus is certainly a good example of one extremity of the greenhouse effect run amok."

The James Webb Space Telescope has taken an intricate look at how pancakes of gas and dust feed infant stars and help them grow before influencing the birth of planets.

The James Webb Space Telescope has spotted the earliest supermassive black hole-driven quasar wind ever seen, pushing away matter at 6,000 times the speed of sound and killing its host galaxy.

Using NASA's exoplanet-hunting spacecraft, TESS, astronomers and citizen scientists have discovered a record-breaking system of three tightly bound stars that could fit between the sun and Mercury.

The James Webb Space Telescope has observed a distant cosmic explosion that erupted in the early universe called "supernova Hope" that could help resolve lingering "Hubble trouble."

The secrets of Mercury's strange magnetic bubble are gradually being unlocked by the BepiColombo spacecraft as it makes its rapid flybys of the world.

On Wednesday (Oct. 2), an annular eclipse swept over the Pacific Ocean, Chile, and Argentina, wowing skywatchers who were on hand to catch the "ring of fire" in all of its glory.

NASA has turned off one of Voyager 2's science instruments as power conservation becomes crucial for the interstellar exploring spacecraft located 12.8 billion miles from home.

The potential detection of "Dyson spheres" indicating advanced alien civilizations may actually be supermassive black hole powerful galaxies obscured by dusty shrouds called "hot DOGs."

Using the James Webb Space Telescope, astronomers have discovered carbon dioxide and hydrogen peroxide at the surface of Pluto's largest moon, Charon, potentially shedding light on its origins.

Astronomers have discovered a low-mass "sub-Earth" planet orbiting the closest solo star to the solar system, Barnard's star, that has a year lasting just three Earth days.

On Wednesday (Oct.2), an annular eclipse will sweep over the globe; here is what you can expect from this ring of fire eclipse, including how it will progress.

Scientists calculated that, on Sunday (Sept. 29), our planet should have captured the asteroid 2024 PT5, claiming it as a very temporary "mini-moon."

Could dark matter decay have given massive clouds of hydrogen gas the time they needed to birth supermassive black holes seen by the James Webb Space Telescope?

A 13-year survey conducted by the VISTA telescope has resulted in the creation of the most detailed Milky Way map ever. It contains a stunning 1.5 billion objects.

A newly discovered Earth-size world orbiting a dead white dwarf star gives scientists a hint of what the solar system may look like in billions of years.
