As strong impulses strike the Earth’s magnetopause, the abrupt boundary between the planet’s magnetosphere and the surrounding plasma, ripples travel...
By analyzing several years of weather radar observations in Finland, a research team led by University of Helsinki scientists has discovered that planes...
A lunar rock sample collected by Apollo 14 astronauts in 1971 contains traces of minerals with a chemical composition common to Earth and very unusual...
Planetary researchers believe that our Moon was created more than 4.4 billion years ago in a catastrophic collision between proto-Earth and a hypothetical...
Freak waves are so called because of their unexpectedly large size relative to the population of smaller waves in which they occur. The 84-foot- (25.6...
On Sunday, December 16, 2018, comet 46P/Wirtanen will make a close pass of Earth. The comet will be at its closest distance to our planet in over four...
Approximately 2.6 million years ago (Pliocene epoch), a tsunami of cosmic energy from a massive supernova or a series of them about 150 light-years away...
Some 252 million years ago, intense volcanic activity belched massive volumes of greenhouse gasses into the atmosphere and triggered rapid changes to the...
An international collaboration of researchers from the Deep Carbon Observatory (DCO) has made several important discoveries, including how much and what...
Volcanoes are not fed by liquid magma formed in large, underground caves called ‘magma’ chambers; instead, they are fed by so-called ‘mush’ reservoirs...
