Mars has fascinated scientists for decades, particularly its intriguing gullies etched into the sandy dunes of theRed Planet. These long, narrow features initially suggested the presence of liquid ...

For decades, chemistry students have learned a simple truth: polar and nonpolar substances don’t mix. Water and oil stay apart.

Scientists from Chalmers University of Technology in Sweden and NASA have made a surprising discovery on Saturn’s largest moon, Titan, that challenges one of the most basic principles in chemistry.

In 1986, excavators surveying land for a power plant in Romania accidentally unearthed a strange cave. It had been sealed up from the atmosphere for 5.5 million years, making the interior a science ...

Chalmers University scientists discovered that Titan’s icy surface allows polar and nonpolar molecules to mix — defying the “like dissolves like” rule. This rare chemistry could explain Titan’s alien ...

The phenomenon is known as noctilucent clouds; it is not weather in the traditional sense. These clouds form in the coldest layers of the upper atmosphere and are often enhanced by water vapor and ...

When scientists squeezed a drop of water between two diamonds to endure pressures tens of thousands of times higher than Earth’s atmosphere, something unexpected happened. The liquid solidified at ...

Ryugu’s samples reveal that water activity on asteroids lasted far longer than scientists thought, possibly reshaping theories of how Earth gained its oceans. A billion-year-old impact may have melted ...

The study projects that Japan’s lower atmosphere will become more humid – by about five grams of water vapor per kilogram of air. As the air grows heavier, storms will rise higher and hit harder.

For millions of years, a tiny icy fragment wandered through space—like a sealed bottle drifting across a cosmic ocean. This summer, that “message in a bottle” arrived in our solar system. Scientists ...

Did life really exist on Mars after all? Unfortunately, there is no conclusive evidence for this yet. Nevertheless, it would seem that some form of life was the driving force behind the mysterious ...

The equatorial regions of Mars are home to unexpectedly enormous layers of ice, and they may have been put there by dramatic volcanic eruptions billions of years ago ...
