This mysterious particle may be proof that black holes can explode
In 2023, physicists detected something that should not have existed: a single subatomic particle called a neutrino carrying an almost unimaginable amount of energy.
This...
Is there really a black hole at the Milky Way’s center—or something even stranger?
For decades, astronomers have believed that a supermassive black hole sits at the heart of our galaxy.
This object, known as Sagittarius A*, is thought...
Is there a link between primordial black holes, neutrinos, and dark matter
Humanity has worked itself into a position where we can detect a single high-energy particle from space and wonder where in Nature it came...
After 50 years, Jupiter’s true size is finally revealed
For more than half a century, scientists believed they had a solid grasp of Jupiter’s size and shape.
As the largest planet in the solar...
Webb Telescope spots rare five-galaxy merger just 800 million years after the big bang
Astronomers have spotted an unexpected and dramatic event in the early universe: a tightly packed collision involving at least five galaxies just 800 million...
Why planets with two suns almost never survive
Planets with two suns, like the famous desert world Tatooine from Star Wars, capture our imagination.
Yet in real life, these so-called circumbinary planets—planets that...
The universe’s first matter really was a soup—and scientists can now see it slosh
In the very first moments after the Big Bang, the universe looked nothing like it does today.
Instead of stars, atoms, or even protons, everything...
NASA rover finds 3.5-billion-year-old Martian shoreline in Jezero crater
Scientists exploring Mars have uncovered strong new evidence that the Red Planet once had wave-washed beaches and long-lasting water activity, making it an even...
For the first time, scientists detect molecule critical to life in interstellar space
The chemical is known as thiepine, or 2,5-cyclohexadiene-1-thione (C₆H₆S), a ring-shaped sulfur-bearing hydrocarbon produced in biochemical reactions.
When examining the molecular cloud G+0.693–0.027, a star-forming...
A new cosmic map reveals how dark matter built the universe we live in
Scientists have created the most detailed map yet of dark matter—the mysterious substance that makes up most of the universe and quietly shapes everything...
A hidden dark matter sheet may be steering our cosmic neighborhood
Astronomers may have solved a long-standing mystery about how galaxies near the Milky Way move through space.
New computer simulations suggest that our galaxy is...
Perseverance Rover discovers an ancient Martian beach, complete with waves
When the rover now named Perseverance landed in Jezero crater in early 2021, scientists already knew they had picked an interesting place to scope...

No collision, no life: How a cosmic crash may have made Earth habitable
Earth is the only known planet that supports life. It has liquid water, a breathable atmosphere, and the right conditions for plants, animals, and...
Scientists found most promising habitable exoplanets
In a new study, researchers identified the most promising target stars for life.
The list is for NASA's new Transiting Exoplanet Survey Satellite (TESS).
It is...
NASA is done setting fires inside its doomed cargo spacecraft
Fire on a spacecraft can be catastrophic.
It can spread quickly in a confined space, and for trapped astronauts, there may be no escape.
It’s fading...
Magma in Martian mantle is still active! It triggers marsquakes again and again
Volcanic activity beneath the surface of Mars could be responsible for triggering repetitive marsquakes, which are similar to earthquakes, in a specific region of...
Cosmology is at a tipping point—we may be on the verge of discovering new...
For the past few years, a series of controversies have rocked the well-established field of cosmology.
In a nutshell, the predictions of the standard model...
