Earth and Moon Seen by Passing Juno Spacecraft

When NASA’s Juno spacecraft flew past Earth on Oct. 9, 2013, it received a boost in speed of more than 8,800 mph (about 7.3 kilometer per second), which set it on course for a July 4, 2016, rendezvous with Jupiter. One of Juno’s sensors, a special kind of camera optimized to track faint stars, also …

UCLA: The Spark of Life: Darwin and the Primeval Soup

New research shows that life probably arose on Earth almost four billion years ago, at a time when the planet’s surface was pounded by huge waves and tides, and periodically devastated by volcanic eruptions. In this talk hosted by The University of California, the authors of “Spark of Life”, UCSD’s Jeffrey Bada and Christopher Wills, …

Markus Landgraf: An Elevator to Space

The concept for a space elevator was actually first published in 1895 by Konstantin Tsiolkovsky but limited by contemporary materials it has until recently been a science fiction dream. These elevators is also referred to as , space bridges, space lifts, space ladders, sky-hooks and orbital elevators.

3 Extreme Climate Fixes

Scishow talks about a few – maybe crazy, maybe reasonable – geoengineering schemes that some scientists have come up with in order to “fix” climate change, including designer clouds, ocean fertilization, and stratospheric shading with sulfur dioxide. The concept of geoengineering refers to “the deliberate large-scale intervention in the Earth’s climate system, in order to moderate global …
