New simulations suggest Earthlike planets may be much more typical than previously thought whereas water worlds may not.

For decades, Saturn has fascinated scientists with its rings, storms, and unusual north-pole hexagon. Now, the James Webb Space Telescope (JWST) has uncovered something even stranger: dark bead-like ...

A new study challenges the idea that Hycean planets are ocean worlds. Chemical reactions between hydrogen-rich atmospheres and molten interiors may reduce surface water, making these sub-Neptunes less ...

Exoplanets, celestial bodies that orbit stars beyond the familiar confines of our solar system, continue to captivate scientists around the world. Their diverse and often unexpected attributes offer ...

TRAPPIST-1e shows no signs of its first atmosphere, but hints of a secondary one remain. Liquid water could still be possible ...

With only 7.5% of Earth's surface covered in fertile, agricultural soil, it's critically important to maintain the soil to grow food, filter water, and regulate the climate.

A new NASA mission will capture images of Earth's invisible "halo," the faint light given off by our planet's outermost atmospheric layer, the exosphere, as it morphs and changes in response to the ...

Current tsunami warning systems rely on seismic data to estimate whether an undersea quake could produce a tsunami, and on ...

ARCA's deep-sea sensors near Sicily detect a highly energetic neutrino, potentially revealing secrets about cosmic phenomena ...

Ice core records of atmospheric hydrogen reveal a huge rise in concentration since the Industrial Revolution which has ...

Punishing trials in a long-awaited sequel tend to obscure its narrative and atmosphere.

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, ...
