Earth's solid-metal inner core is a key component of the planet, helping to give rise to the magnetic field that protects us from harmful space radiation, but its remoteness from the planet's surface means that there is much we don't know about what goes on down there. But some secrets of the inner core are being revealed by acoustic waves passing through the planet's heart and iron squeezed to enormous pressures in the lab.
A fundamental property of the rarest element on Earth, astatine, has been discovered for the first time, scientists say.
If an extreme solar storm aimed at the Earth hits in just the right way, it could put interconnected electrical grids around the world at serious risk, experts say.
Scientists have discovered a striking similarity between certain ocean currents on Earth and the bands that characterize the surface of large, gaseous planets like Jupiter. Boris Galperin of the University of South Florida's College of Marine Science in Saint Petersburg and colleagues in the United States, Israel, and Japan report their findings later this month in Geophysical Research Letters, published by the American Geophysical Union.
A recently discovered comet is closer than it's ever been to Earth, and stargazers in the Northern Hemisphere finally get to see it.
The Earth's oceans and the water that once flowed on Mars likely came from a similar source: meteorites that landed on the planets when they were first forming, new research suggests.
Surrounding our planet are rings of plasma, part of Earth’s magnetosphere, which are pulsing with radio waves. These aren’t audible to the human ear, but radio dishes and antennas always pick them up. Recently, NASA scientists recorded some of the Earth’s pulses and transformed them into acoustic waves – the end result is a short song chanted by our very planet.
Walking barefoot on the earth has been a staple part of human and animal life since the beginning of time. In the past couple of generations, humans have made shoes, sandals and boots that insulate us from the natural energies of the Earth
The B612 Foundation - named for the asteroid that was home to the prince in The Little Prince - has announced a plan to build, fly and operate the first private space telescope.
