Evidence points to ‘iron snow’ falling on Earth’s inner core

Geologists have found evidence to suggest “iron snow” falls in the Earth’s core

A team of geologists from China and the US have found evidence to suggest that snow may be falling within the broiling hot core of planet Earth. Of course, this isn’t your everyday surface snow – the researchers say that these flakes would be made of iron alloys, gently settling down onto the solid inner core through the more fluid outer core.

Play Solar Tricktionary! :: NASA Space Place

The wind speed of a devastating Category 5 hurricane can top over 150 miles per hour (241km/hour.) Now imagine another kind of wind with an average speed of 0.87 million miles per hour (1.4 million km/hour.)

Welcome to the wind that begins in our Sun and doesn’t stop until after it reaches the edge of the heliosphere: the solar wind.

Tidal forces carry the mathematical signature of gravitational waves

Written by Emerging Technology from the arXiv

gravitational waves

In February 2016, an international team of physicists announced the first direct observation of gravitational waves. The waves had been produced by the gigantic collision of a pair of black holes, each about 30 times the mass of the sun—a smash so cataclysmic that it sent ripples through the fabric of spacetime.

Humans First!

Written by G.C. Beaujon

How much of our humanity are we willing to lose? It would appear that this question is becoming most pertinent in our age. But another, more fundamental, question foregrounds this one – what is a human being? Are people bio-mass? If so, then only one idea is required to exist on this planet, namely, how best to manage populations.

An Aether Perspective on Stellar Aberration

Written by Dr. Raymond H.V. Gallucci, P.E. (ret.)

Cosmic Adventure 4.5 Proving the Lights

Abstract.  It has been known for nearly three centuries that, to view a clear image of a star through a telescope, it is necessary to tilt the telescope slightly forward in the direction of the earth’s motion, a phenomenon known as “stellar aberration.”

By the mid-nineteenth century it had become generally accepted that much of Europe had once been covered by glacier.

The cause for such dramatic shifts in the Earth’s climate was unknown until James Croll (pictured above), a janitor, at Anderson’s University in Glasgow proposed the idea that variations in the Earth’s orbit might have precipitated ice ages.
