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).

Last week, NASA’s New Horizons spacecraft began sending stunning shots of Pluto on its flyover back to the Earth. Here is a beautiful Pluto flyover video created from the images from New Horizons’ closest approach to the dwarf planet on July 14.

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 exact moment of the Calbuco Volcano eruption captured by a currently anonymous hiker in Chile. The volcano erupted on April 22, 2015, for the first time in four decades (the last one was in 1972).

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)!
The Calbuco volcano in southern Chile has erupted twice and the people have been evacuated. It is the first eruption of the stratovolcano in 42 years; results in huge ash cloud over a mountainous area in the south of Chile.
The amazing footage from the area shows a huge column of lava and ash being sent several kilometers into the air.

The standard maps we see every day use Mercator Projection, a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. It developed for navigational purposes, has often been used in world maps. And like all the other types of projections, it can be deceptive.

In fact, every map tells lie, since it’s impossible to transform perfectly the three-dimensional world into two-dimensional surfaces like paper or computer screen. Map projections are necessary for creating maps and every map projections distort the surface in some fashion (a map projection is a systematic transformation of the latitudes and longitudes of locations on the surface of a sphere or an ellipsoid into locations on a plane).
