Scientists map the largest structures in the universe
clusters of galaxies.
These gigantic structures, which contain hundreds or even thousands of galaxies bound together by gravity, offer important clues about how the universe...
Astronomers discover a surprisingly mature spiral galaxy from the early universe
Astronomers have discovered a beautiful, well-formed spiral galaxy from a time when the universe was still very young—only 1.5 billion years after the Big...
Astronomers discover giant spinning thread of galaxies 140 million light-years away
Astronomers have discovered one of the largest rotating structures ever seen in the universe: a razor-thin line of galaxies inside a massive, spinning cosmic...
Scientists capture the first high-detail “real-time” images of stars exploding
Astronomers have captured the most detailed close-up images ever taken of stars exploding, known as novae.
These pictures were taken within days of the eruptions...
Did asteroids invent gum billions of years ago?
What is “gum”? Most people have probably never considered this question, and might answer something like a chewy material you can put in your...
Do super-Jupiters look like Jupiter? New Webb discovery says the answer is more surprising...
At first glance, giant planets called super-Jupiters might seem like close cousins of Jupiter. Some are even ten times more massive.
For years, astronomers assumed...
New tech could shield space electronics from deadly cosmic radiation
Modern life depends heavily on electronics that can survive in extreme environments.
Satellites that provide TV broadcasts, GPS signals, phone services and internet must operate...
Astronomers find hidden star that solves a major cosmic dust mystery
Only 70 light-years from Earth, a star called Kappa Tucanae A hosts one of astronomy’s strangest mysteries.
Around it swirls dust so scorching—more than 1,000...
Asteroid Bennu holds clues to how life began: Sugars, organics, and stardust
NASA’s OSIRIS-REx mission brought back pristine pieces of the asteroid Bennu in 2023—and these tiny grains are turning out to be a treasure chest...
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,...

An exploding black hole could be seen within the decade, study finds
For decades, physicists have suspected that black holes might not last forever—that at the very end of their lives, they could explode in bursts...
NASA’s DART mission hits asteroid in first-ever planetary defense test
After 10 months flying in space, NASA’s Double Asteroid Redirection Test (DART) – the world’s first planetary defense technology demonstration – successfully impacted its...
Galaxies discharge metal-tinged gases into the universe
Astronomers at the University of California, San Diego have learned more about what exhaust from galaxies is composed of and how galactic emissions are...
Asteroid samples returned to Earth were immediately colonized by bacteria
We’ve known for a while that complex chemistry occurs in space.
Organic molecules have been detected in cold molecular clouds, and we have even found...
Why don’t we see robotic civilizations rapidly expanding across the universe
In 1950, while sitting down to lunch with colleagues at the Los Alamos Laboratory, famed physicist and nuclear scientist Enrico Fermi asked his famous...
