The astronauts aboard the International Space Station (ISS) occasionally take photos of Earth. Some of them are really cool. Here are the top ten most beautiful Earth images taken from the ISS in 2015 (well, IMHO, of course).

Aboard the International Space Station, Expedition 46 Commander Scott Kelly of NASA, Flight Engineer Tim Kopra of NASA and Flight Engineer Tim Peake of the European Space Agency wished the people of Earth a Happy New Year. Kelly is nearing the completion of the ninth month of a year-long mission on the orbital laboratory, while Kopra and Peake arrived December 15, 2015, to begin a six-month mission on the complex.

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.

Thousands of (more than 9600) photos taken by the astronauts during the Apollo Program (1966-1972) now on the popular image and video hosting website Flickr. Network and administrative data systems specialist and Project Apollo Archive‘s creator Kipp Teague recently updated new and unprocessed versions of original NASA photo scans to the image sharing site.

You can see all the archive on the Project Apollo Archive page on Flickr. The photos are taken by the Sweden-made “Hasselblad” cameras from the Earth, from the Lunar orbit and on the surface of the Moon by astronauts with their chest-mounted cameras.
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).

NASA’s space observatory Kepler may have discovered a possibly Earth-like planet, a rocky world orbiting a Sun-like star at almost the exact same distance Earth orbits our own Sun: Kepler-452b!
Continue reading Earth 2.0: Kepler-452b
“The new Earth” is located 1,400 light-years from us. It orbits a Sun-like star that is 4% more massive and 10% brighter than our Sun. Kepler-452b is 1.6 times the size of Earth and the scientists are fairly sure that it is a rocky world.
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.

At the Sun-Earth L1 Lagrangian point, 1,500,000 km (930,000 mi) from Earth; NASA’s Deep Space Climate Observatory took an amazing photo of the entire sunlit side of Earth on July 06, 20145. The photo was taken by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope.

The final image showing the North and Central America was generated by combining three separate images to create a photographic-quality image. The camera takes a series of 10 images using different narrowband filters — from ultraviolet to near infrared — to produce a variety of science products. The red, green and blue channel images are used in these color images.
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.
