Researchers track slowly splitting ‘dent’ in Earth’s magnetic field

A small but evolving dent in Earth's magnetic field can cause big headaches for satellites. Earth's magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the... Continue Reading →

Geologists determine early Earth was a ‘water world’ by studying exposed ocean crust

The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say after analyzing oxygen isotope data from ancient ocean crust that's now exposed on land in Australia. And that could have major implications on the... Continue Reading →

Earth’s heavy metals result of supernova explosion, research reveals

That gold on your ring finger is stellar -- and not just in a complimentary way. In a finding that may overthrow our understanding of where Earth's heavy elements such as gold and platinum come from, new research by a... Continue Reading →

3D Earth in the making

A thorough understanding of the ‘solid Earth’ system is essential for deciphering the links between processes occurring deep inside Earth and those occurring nearer the surface that lead to seismic activity such as earthquakes and volcanic eruptions, the rise of mountains... Continue Reading →

Aerosol Earth

Aerosols are all around us. From the smoke from a fire, to the dust in the wind to the salt in sea spray — these solid particles and liquid droplets are always swirling in our atmosphere, oftentimes unseen. The Goddard Earth Observing... Continue Reading →

The Umbra of Earth

The dark, inner shadow of planet Earth is called the umbra. Shaped like a cone extending into space, it has a circular cross section most easily seen during a lunar eclipse. For example, on January 21 the Full Moon slid across the northern half... Continue Reading →

Oxygen ions sent from Earth have been spotted on the moon

Earth’s atmosphere may have been leaking oxygen onto the moon for billions of years. Energetic particles from the solar wind bombard the moon nearly all time, except for a five-day window each month, when Earth passes between the sun and... Continue Reading →
