The foggy season has arrived in San Diego, often called May Gray and June Gloom. But how does it form, and why does it clear some days and not others?

By studying seismic waves, researchers have found a layer deep beneath the surface of Mars that could contain enough liquid ...

Something like Earth's aquifers, where groundwater seeps into rock pores. We calculated the "aquifer layer" on Mars could hold enough water to cover the planet in a global ocean 520–780m deep—several ...

According to geologists at the UK’s Heriot Watt University, gigantic waves of mud and sand sediment about 250 miles off the ...

While the region closest to Alaska still has stable stratification of sea water layers, the combination of factors in other regions of the Arctic Ocean drives what researchers say is a positive ...

Beneath Mars’ barren crust, scientists may have found a hidden oasis—liquid water, deep below, waiting to reshape our view of ...

We calculated the “aquifer layer” on Mars could hold enough water to cover the planet in a global ocean 520–780m deep — several times as much water as is held in Antarctica’s ice sheet.

Researchers have made micro plastic measurements in the Atlantic Ocean for the first time. In the first 200 meters of the water layer, they estimate that there are approximately 12 to 21 million ...

Astronomers have long been intrigued by the makeup of the asteroid belt’s largest body. When it was first spotted in 1801, ...
