What’s inside a neutron star? New study points to answers in gravitational waves
Neutron stars are among the most mysterious objects in the universe.
Formed when massive stars collapse after exploding as supernovae, these incredibly dense objects pack...
Scientists decode ancient magnetic signals in asteroid Ryugu samples
Scientists studying tiny samples from the asteroid Ryugu have uncovered new clues about the magnetic environment that existed when the solar system first formed.
The...
How old is the universe? The oldest stars in the Milky Way may hold...
How old is the universe?
Scientists have long tried to answer this question, but different measurement methods have produced conflicting results.
Now, researchers from the University...
The coldest ‘stars’ in the galaxy might actually be alien megastructures
Ever since physicist Freeman Dyson first proposed the concept in 1960, the "Dyson sphere" has been the holy grail of techno-signature hunters.
A highly advanced...
Scientists spot unexpected cold region inside Jupiter’s northern lights
Jupiter’s northern lights are the most powerful in the solar system, but new observations from the James Webb Space Telescope (JWST) have revealed surprising...
Mars Express reveals a landscape filled with ancient craters on the red planet
A new image captured by the Mars Express orbiter offers a striking view of one of the most heavily cratered regions on Mars.
The image...
Scientists discover super-tough microbe that could survive a journey from Mars to Earth
Life on Earth may not be as isolated as we once thought. New research from Johns Hopkins University suggests that tiny life forms could...
Red dwarf stars might starve alien plants of the quality light they need to...
Red dwarfs make up the vast majority of stars in the galaxy.
Such ubiquity means they host the majority of rocky exoplanets we’ve found so...
How long do civilizations last
It is one of the most famous questions in science, and it was asked, as legend has it, over lunch.
Enrico Fermi, the physicist who...
Scientists discover cost-saving way to build structures on the moon
Scientists are exploring an exciting idea for future space missions: building structures on the Moon using the Moon’s own soil.
A new study shows that...
Giant dying stars create tiny cosmic dust that could form new planets
A new study shows that some of the largest and most powerful stars in the universe are producing incredibly tiny particles of carbon dust—material...
New method may finally resolve the “Hubble tension” puzzle
Scientists have known for nearly a century that the universe is expanding, with galaxies moving away from each other over time.
The speed of this...

Astronomers watch a giant black hole “wake up” for the first time
Astronomers have caught a rare cosmic event in action—a supermassive black hole “waking up” after a long period of inactivity. Using the Very Long...
Scientists expand cosmic ‘cheat sheet’ to search for alien life in exoplanets
To understand where exoplanets are in their own evolution, astronomers can use Earth’s biological milestones as a Rosetta stone.
Using nature's color palette from early...
Statistically speaking, we should have heard from aliens by now
The Fermi Paradox, named after physicist Enrico Fermi, highlights a contradiction in our understanding of alien life: despite billions of stars with potentially habitable...
Solar storms could scramble whales’ navigational sense
When our sun belches out a hot stream of charged particles in Earth's general direction, it doesn't just mess up communications satellites.
It might also...
The Moon’s oldest crater reveals new secrets about its past
The South Pole-Aitken basin is the moon’s largest and oldest visible crater, formed around 4 billion years ago.
It’s like a giant time capsule, holding...
