Why the Small Magellanic Cloud is behaving so strangely
Astronomers have discovered that one of our closest neighboring galaxies is going through a dramatic transformation—and they can watch it happening in real time.
The...
Giant craters may reveal if Psyche is a lost planetary core
When we think of asteroids, we almost immediately think of giant rocks bouncing around like the iconic chase scene in Empire Strikes Back, and...
Earth was already moving 3.5 billion years ago, study finds
The story of our planet is written in the slow movement of its surface.
Over billions of years, shifting tectonic plates have shaped continents, opened...
How will Martian gravity affect skeletal muscle
NASA and the China National Space Agency (CNSA) plan to send astronauts to Mars as early as the next decade.
Naturally, this ambitious goal requires...
This pair of brown dwarfs can’t get enough of each other
Binary stars are known to transfer mass to one another. In extreme cases, mass transfer can even cause a supernova explosion. That happens when...
When two ‘failed stars’ team up to light the sky
Brown dwarfs are often called “failed stars” because they are too small to keep nuclear fusion going in their cores, the process that makes...
Scientists discover “rotten egg” planet with a massive ocean of lava
Astronomers have discovered a strange new kind of planet beyond our solar system—one that may be covered by a vast, long-lasting ocean of molten...
A giant space rock’s scars may reveal how planets were born
Asteroid 16 Psyche has puzzled scientists for more than 200 years.
Now, new research suggests that its large craters could hold the key to understanding...
A “cotton candy” planet wrapped in haze leaves scientists puzzled
Astronomers have taken a closer look at one of the strangest planets ever discovered, and it is raising more questions than answers.
The planet, called...
Scientists discover one of the oldest stars ever, with almost no iron
Astronomers have discovered one of the oldest and most primitive stars ever found, offering a rare glimpse into the early universe.
The star, named PicII-503,...
Nearby galaxies suggest the universe may be expanding more slowly than thought
For decades, scientists have tried to measure how fast the universe is expanding.
This expansion rate is known as the Hubble constant, and it plays...
Astronomers discover powerful “cosmic laser” shining from halfway across the universe
Astronomers using a powerful radio telescope in South Africa have discovered an extraordinary cosmic signal coming from more than 8 billion light-years away.
The signal...

Astronomers spot a black hole shredding a star far from any galactic center
In a groundbreaking discovery, astronomers have detected powerful radio signals from a black hole tearing apart a star—and surprisingly, it didn’t happen in the...
Scientists warn: Moon dust could threaten future astronauts
New research using moon rocks from the Apollo missions has revealed hidden dangers facing future astronauts.
The study, published in Scientific Reports and led by...
Would a deep-Earth water cycle change our understanding of planetary evolution
Every school child learns about the water cycle--evaporation, condensation, precipitation, and collection.
But what if there were a deep Earth component of this process happening...
Solar beats nuclear at many potential settlement sites on Mars
The high efficiency, light weight and flexibility of the latest solar cell technology means photovoltaics could provide all the power needed for an extended...
Webb Telescope unveils rare galaxy collision from 7 billion years ago
Astronomers using NASA's James Webb Space Telescope have discovered a rare and intriguing cosmic formation that looks like a question mark in space.
This shape...
