Early in its evolution, Earth suffered an impact by a large body that catapulted pieces of the young planet's mantle into space. Gravity pulled many of these pieces together to form the moon, which took up orbit around its creator. The late-stage phase of planet formation with protoplanets...
It will begin to swell, blasting interplanetary space with savage solar winds that begin to strip away its upper layers. Though our sun isn't massive enough to explode as a supernova, it will turn into a red giant star, possibly expanding beyond the orbit of Earth. And that's not good...

Like a diamond undergoing extreme heat and pressure to form in the deep layers of the earth,we need experiences of contraction and discomfortto grow and evolve on all levels. In the poetic words of Rumi, the wound (core wound) is the place where the Light (the presence of the Soul, Spi...
How did Earth form? How old is the universe? And in another effort to calculate the age of the planet, scientists turned to the rocks that cover its surface. However, because plate tectonics constantly changes and revamps the crust, the first rocks have long since been recycled, melted ...
There are two layers of silicon in solar cells. Each one is specially treated, or "doped," with phosphorus and boron to create positive and negative sides of the solar cell, respectively. When photons hit the solar cells they create an electric field at the junction between the layers. Th...
To trap in the earth’s accumulated warmth, drape young or small trees with burlap, sheets, or tarps that extend to the ground, and use a frame or stakes to reduce contact between the cover and the leaves of the tree. You can keep the covers in place with twine or clothespins. You ...

If both of these automated systems fail to work, the crew can initiate the process from its console in the capsule. As a very last resort, signals from thermal sensors on the tail of the vehicle will detect the rising heat from the increasing friction of the Earth's atmosphere as the spa...
—When did Antarctica become a continent? —What is the rarest mineral on Earth? —How big is the largest possible earthquake? As geologists make sense of this dynamic puzzle, Earth's moving plates create some fascinating scenarios. The Pacific Plate is probably the fastest, moving northwest 2.8...
