Space Elevator Feasibility | How Space Elevators Will Work

Two scientists have released a proof-of-concept paper that reveals designs for a space elevator. Solar-powered vehicles would move along a carbon nanotube cable stretching from the moon down into Earth’s geostationary field.Scientists have long suggested that space elevators could dramatically reduce the cost of sending humans into space.For decades, the idea of riding an elevator…

Mysterious ‘alien’ shapes on Venus are doing strange things to its climate, scientists say

Unexplained shapes seen on Venus, which some scientists have suggested could be signs of alien life, are even more mysterious than we thought. Researchers studying the Venusian surface have found that the strange dark spots are affecting the planet’s climate, after a new breakthrough study. Scientists have known about the dark “splotches” on the surface…
