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.

Photographs taken during the Apollo program now on Flickr

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.

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 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).

Earth 2.0: Kepler-452b

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!

“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.

“EPIC” Earth Image by NASA

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.

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.

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.

Ultra HD Video from the International Space Station

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.

Philae (Rosetta’s Lander) Wakes Up From Hibernation

Good news! ESA’s (European Space Agency) robotic lander Philae finally received enough solar radiation and now is out of hibernation. On the Rosetta blog, the ESA announced that “The signals were received at ESA’s European Space Operations Centre in Darmstadt at 22:28 CEST on 13 June. More than 300 data packets have been analyzed by the teams at the Lander Control Center at the German Aerospace Center (DLR).” It is the first contact with the spacecraft since going into hibernation in November.

According to the agency, “Philae ‘spoke’ with its team on the ground for 85 seconds, via Rosetta.”

The World Is Going To End, Again, In September 2015? Of Course Not

There’s a super crappy 1982 science-fiction movie named “The man who saves the world”. The story is absurd – in the opening, a narrator speaks a lot. He tells about somebody attacking on Earth, but a layer made by human brains (?) is protecting our planet. Then the battle begins: two space cadets of the world get shot in the space, crash-land on a desert planet, where an evil wizard seeks the ultimate power to take over the world. Although the movie borrows some background footage from Star Wars, the plot is mostly unrelated.

If a movie is bad then you should not watch it at all. But if a movie is really, really bad then it makes more fun than a good movie. This is one of those movies, called B-movies. Perhaps this is a C-movie.
