BERKELEY — Eta Carinae, the galaxy’s biggest, brightest and perhaps most studied star after the sun, has been keeping a secret: Its giant outbursts appear to be driven by an entirely new type of ...

Some volcanoes can produce eruptions so powerful they release oceans of dust and toxic gases into the air, blocking out sunlight and changing a planet’s climate for decades. By studying the topography ...

When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through a ...

Add to the long list of global warming concerns that melting ice caps could trigger more volcanic eruptions. Worse, researchers said Monday at a scientific conference in Prague, the increasing ...

Volcanoes often give little warning before they erupt, but now scientists have discovered an unexpected early warning sign—trees. This new finding comes from a joint study by researchers from NASA, ...
