Timeless Dreams – the Earth in daytime and nighttime

You must watch this! An amazing video by the filmmakers led by Julian Tryba: in May 2015, over the span of three weeks, they traveled in the Southwest of the United States (3,000 miles through Utah, Arizona, Nevada, and California) and filmed timelapses of several strikingly beautiful landscapes. Then they spliced the films together to create this wonderful video, a strange day-night world.

Moon Transiting the Earth – EPIC View

An “EPIC” animation of the Moon transiting the Earth created with actual satellite images of the far side of the moon, illuminated by the Sun. The images are taken by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope attached the Deep Space Climate Observatory (DSCOVR). While the moon was crossing between the DSCOVR and the Earth, EPIC took these beautiful photos almost one million mile from Earth.

The distance between the Moon and Earth varies from around 356,400 km to 406,700 km at the extreme perigees (closest) and apogees (farthest).

A Bowling Ball and Feather Falling in a Vacuum (video)

It’s one of the basic Newton laws: how fast something falls due to gravity is determined by a number known as the “acceleration of gravity”, which is 9.81 m/s2 at the surface of Earth. The acceleration of gravity, shortly “a” means that in one second, any object’s downward velocity will increase by 9.81 m/s because of gravity. The gravity accelerates everything at exactly the same rate.
