Our research on a Martian meteorite provides new clues about early surface conditions on the red planet.
In 100 years, perhaps this map showing humanity clustering around the equator will seem “so 21st century.”
Researchers have discovered 830-million-year-old microbes living inside a salt rock on Earth. Could the same occur on Mars?
On the largest scales, galaxies don't simply clump together, but form superclusters. Too bad they don't remain bound together.
While Mars is known as a frozen, red planet today, it has all the evidence we could ask for of a watery past, lasting for approximately the first 1.5 billion […]
Binary black holes eventually inspiral and merge. That's why the OJ 287 system is destined for the most energetic event in history.
Chemical changes inside Mars' core caused it to lose its magnetic field. This, in turn, caused it to lose its oceans. But how?
America’s war in Southeast Asia is fading fast from memory. These maps offer a horrific reminder.
The observable Universe is 92 billion light-years in diameter. These pictures put just how large that is in perspective.

Here's why mega-eruptions like the ones that covered North America in ash are the least of your worries.
Theoretically, we know what happened on the red planet. Here’s how we’ll find out whether we’re right. When it comes to the worlds beyond Earth in our Solar System, it’s only […]
To preserve biodiversity and ecosystems, protected areas should be connected into a gigantic World Park.

The majority of countries are democracies. But how many people enjoy democratic rights?
Here’s how it works.
Gigantic ranges called "supermountains" formed twice in Earth's history, and they may have had a profound influence on evolutionary history.
Any dataset that can be quantified over time can be turned into a contest that is both exciting and (a little bit) enlightening.
The light from Earendel took 12.9 billion years to reach Hubble. The star is millions of times brighter than our Sun and 50 times as massive.
