These Researchers Want to Run a Cable From the Earth to the Moon

by Dan Robitzski, Futurism

It’s a space elevator concept that could actually work.

It would be much easier to escape Earth’s gravity if you could skip the energy-intensive rockets.

That’s the idea behind the Spaceline, a newly-proposed type of space elevator that would link the Earth and the Moon in a bid drastically cut the cost of space travel.

Sun and Earth Aligned: Ancient Andean Calendar is Illuminated on the Atacama Desert

by Ashley Cowie, Ancient Origins

On the winter solstice of 2017 a dedicated historian at Chile’s Pre-Columbian Art Museum in Santiago, Dr. Cecilia Sanhueza, was following a hunch in the Atacama Desert, Chile. She observed “a row of three cairns… and two square piles of stones, each about 1.2 meters (four feet) high” to see how they coordinated with the rising sun on the winter solstice. Her discovery that night is being heralded as big news, according to an article in The Economist. Continue reading Sun and Earth Aligned: Ancient Andean Calendar is Illuminated on the Atacama Desert

Earth’s core may have hardened just in time to save its magnetic field

by Carolyn Gramling, ScienceNews

This shift both prevented the protective magnetic field from collapsing and recharged it.

Earth’s inner core solidified sometime after 565 million years ago — just in time to not only save the planet’s protective magnetic field from imminent collapse, but also to kick-start it into its current, powerful phase, a new study suggests.

Solar wind is blasting Earth’s oxygen onto the surface of the Moon

Seeding the Moon with the ingredients of life

We all know that there’s no air to breathe on the Moon, but new evidence suggests that the lunar surface is continually being showered by oxygen escaping Earth – and may have been for billions of years, since Earth’s atmosphere developed.

Who needs asteroids? Earth makes its own water deep within the mantle

by Peter Dockrill, Science Alert

Our planet could be self-sufficient

Life on Earth depends on the existence of water, but despite it covering some 70 percent of the planet’s surface, scientists have never really been sure where it all comes from.

While the popular view has been that icy asteroids or comets could have brought water to Earth billions of years ago in an epic collision that filled the planet’s oceans, a new study shows Earth’s inner regions had the necessary ingredients to make water all along, hidden deep underground.
