What time is it on Mars? Scientists finally have a precise answer
On Earth, telling time is easy. Our clocks are synchronized using atomic clocks, GPS satellites, and fast communication networks.
But according to Einstein’s theory of...
Scientists detect static discharge on airplanes using giant European telescope
Scientists have accidentally uncovered a surprising behavior in commercial airplanes: they emit radio waves when they release built-up static electricity.
This discovery, made by an...
Two hot stars passed near our solar system and left a lasting mark
Around 4.4 million years ago—long before humans existed—two massive, blazing-hot stars swept past our solar system.
They didn’t come close enough to pose any danger,...
Chang’e-6 uncovers strange “sticky” soil on the moon’s far side
Scientists have finally taken a close look at the first-ever soil samples brought back from the far side of the moon, and the results...
Why galaxies die faster in crowded regions
Astronomers have long known that galaxies grow and change over billions of years, but new results from a major international project show that where...
The universe was warm before it was bright
So first the Big Bang happens. Everything is incredibly hot and dense; there are photons flying everywhere, but they keep colliding with electrons and...
Scientists capture ultra-rare, ultra-sharp images of powerful solar flares
Scientists have achieved something that almost never happens in solar research: they captured high-resolution images of an active region on the sun at the...
Stars surprisingly survive near the Milky Way’s black hole, study finds
Astronomers have long believed that the region around the Milky Way’s central black hole, Sagittarius A*, is one of the most dangerous places in...
Meteorites are ancient time capsules that reveal how our solar system was born
When a meteor flashes across the night sky, it’s more than a beautiful streak of light.
It’s a delivery from deep space—an ancient piece of...
Astronomers discover 400 “sibling” star clusters hidden in the Milky Way
Astronomers have uncovered more than 400 pairs of star clusters in our Milky Way—cosmic siblings that were born together or later became partners as...
Living microbes found in a meteorite crater may offer clues to life on Mars
Scientists have discovered living, methane-producing microbes deep inside a massive meteorite impact crater in Sweden, and the find could change the way researchers think...
Scientists discover a fast-spinning red giant star orbiting a silent black hole
Astronomers have uncovered the unusual history of a distant red giant star by “listening” to tiny vibrations rippling through it.
These vibrations, known as starquakes,...

New study reveals a star’s unexpected survival
As the star is shredded, its remnants are transformed into a stream of debris that rains back down onto the black hole to form a very hot, very bright disk of material swirling around the black hole, called an accretion disc.
Dust particles from Mars can make little sparks
Friction that results from dry Martian dust particles making contact with each other may produce electrical discharge at the surface and in the planet’s...
Earth-size stars and alien oceans: An astronomer explains the case for life around white...
The sun will someday die. This will happen when it runs out of hydrogen fuel in its core and can no longer produce energy...
Scientists find unexpected old surface on near-Earth asteroid Bennu
In a new study, researchers have discovered that the surface geology on asteroid Bennu is older than expected.
Bennu is a carbonaceous asteroid whose surface...
Scientists discover possible rogue planets hidden in old survey data
Scientists have found what appear to be rogue planets hidden in old survey data.
