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 to 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 miles 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).

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.

This also means a heavy object like a bowling ball and a lightweight object like a feather should fall down with the same speed, regardless of their shapes. But we see this phenomenon very rarely in our daily lives. The reason is the air resistance. That’s why people (including Aristotle) thought that the heavier objects fall faster for thousands of years.
An amazing ultra high definition video, from the International Space Station (ISS). The ISS has introduced a new 4K Ultra High-Definition (UHD) video, providing an unprecedented look at what it’s like to live and work aboard the International Space Station.

The world’s deepest lake is the Lake Baikal, which has a depth of 1,642 meters (5,387 feet). It is a rift lake in the south of the Russian region of Siberia. Its bottom is at 4,215 feet (1,285 meters) below the sea level. In terms of volume, Lake Baikal is also the world’s largest freshwater lake; it contains roughly 20% of the world’s unfrozen surface fresh water with 23,615.39 cubic kilometers (5,700 cubic miles). It contains more water than that of all the North American Great Lakes combined.

When I was a child, I always dreamed about watching Earth from the space. Back in the 1980s, we were almost sure that around the year 2000, the space travel would be so common. Remember TV shows like “Space: 1999”. Unfortunately, the space race lost its momentum during the 1990s and 2000s.

But thanks to the Internet and computer science, we all able to see the earth from the space. And live! And HD! 24 hours a day (the feed will sometimes go down as the signal switches between the cameras – the screen is grey when the cameras are down)!
