The Planets That Go Quiet While Their Stars Still Shine
A world can receive the right amount of sunlight and still lose the machinery that keeps its climate alive.
The Same Unidentified Mark Appeared on Titan and Pluto
Two frozen worlds. One missing sliver of infrared light. And a chemical story we cannot yet read.
Mars Is Erasing Its Own Past While We Watch
The strangest thing about Mars may not be what is buried beneath its surface.
Europa’s Ocean May Be Hiding a Terrible Silence
Two spacecraft are on their way to Jupiter’s icy moons. A study raises a troubling question about the energy beneath Europa’s ocean.
The Planet That Wouldn’t Keep Its Core
Juno found that Jupiter’s center is less like a buried stone and more like a question without a clean edge. Then a leading explanation for how it got that way ran into trouble.
Life May Not Need a Spaceship to Cross Between Worlds
Moss spores spent nine months exposed outside the International Space Station and most of them still germinated. The experiment does not prove panspermia, but it makes one of its strangest requirement
A Planet 48 Light-Years Away May Have an Atmosphere. Then JWST Made It Stranger.
LHS 1140 b may be one of the most important worlds we have ever found beyond the Solar System, but the closer astronomers look, the stranger the planet becomes.
Silicon Should Have Won the Contest for Life. So Why Are You Made of Carbon?
Earth is overflowing with silicon. Carbon is comparatively scarce. Yet every living thing we have ever discovered is built around carbon, and the reason reaches from the sand beneath your feet to a st
Water Has a Second Life We Are Only Beginning to See
A glass on your desk, a lake under winter ice, an ocean sealed inside a moon. The same molecule may be keeping more than one arrangement within reach.

Cassini Found an Alien Ocean. Then Humanity Killed It.
The spacecraft’s greatest discovery made its continued existence unacceptable
Did Life Begin Twice? The First Cells May Have Escaped from Stone
A study suggests biology did not arrive fully formed. Part of its metabolism may have assembled inside hydrothermal rock, then completed itself independently along the two oldest branches of life.
They Made Ice at 4,274°F. It May Be Hiding Inside Countless Alien Worlds
Scientists crushed water beneath more than two million atmospheres and heated it beyond iron’s ordinary-pressure melting point. It became a crystal with a liquid moving through it.

The Sun May Have Abandoned Earth. What Happened Next Could Be Us.
A scientific review argues that the solar system may have struck interstellar clouds that crushed the heliosphere inside Earth's orbit, exposing the planet to alien gas and intense radiation.
The Sun Bombarded the Young Earth. The Sky Began Making Life’s Ingredients.
An experiment suggests ancient proton storms may have warmed a faint world while manufacturing amino-acid precursors at the same time.

The Planet That Vanished From the Star Next Door
Webb saw a possible Saturn-mass world beside the nearest solar twin. When it looked again, the planet was gone. Now a recommissioned telescope may get the second look astronomy has been waiting for.

Life May Have Begun Twice on Earth, and That Changes the Search for Alien Life
A study suggests that bacteria and archaea independently completed the journey from chemistry to free-living cells, raising a profound possibility about how readily the universe creates life.
The Fermi Paradox May Be Hidden in Our DNA
The Bio-Archive Hypothesis asks whether life itself could be a cosmic information-storage system carrying a message across worlds, extinctions, and billions of years.
They Came in Peace. Their Biology Did Not.
The darkest first-contact scenario does not begin with an invasion. It begins with two living worlds touching for the first time.
The Silence May Be the Answer
The universe may not be empty. It may simply be what remains after everyone else is gone.

The “Habitable” Planets That May Be Anything But
The universe has given us thousands of worlds, but the closer we look, the less welcoming many of them become.
What If the Survivors Learned Never to Speak?
The silence of the universe may not mean we are alone. It may mean every civilization that survived learned the same rule.

They Were Found: The Darkest Answer to the Fermi Paradox
What if the silence of the universe is not emptiness, but a galaxy-size crime scene?

The First Alien Signal May Come From a Dead Civilization
What if first contact isn’t a greeting from the stars, but a warning from a civilization that didn’t survive itself?

Earth May Be Special Because It Is Dry Enough to Escape
What if the universe is full of life that never gets a sky? Why Earth may be rare not because it has water, but because it has land.
What If Earth Is the Exhibit?
The most terrifying answer to “Where is everybody?” may be that they’re already here, and deliberately refusing to answer.

What If Intelligence Is Evolution’s Most Dangerous Mutation?
The Biological Great Filter may be the darkest answer to the Fermi Paradox.

What If the Universe Is Silent Because Something Ate Everybody?
A civilization does not need to build something evil to destroy itself. It only needs to build something that keeps going.

This Organism Eats Stars
Astrophage from Project Hail Mary may be fictional, but the reason it feels so disturbing is that almost everything about it follows a rule.
