NASA| Moon Phases 2017 – Northern Hemisphere – 4K

 

By: NASA Goddard

Originally published on Dec 22, 2016
This 4K visualization shows the Moon’s phase and libration at hourly intervals throughout 2017, as viewed from the northern hemisphere. Each frame represents one hour. In addition, this visualization shows the Moon’s orbit position, sub-Earth and subsolar points, distance from the Earth at true scale, and labels of craters near the terminator.

Showstopper Nov. 14 Supermoon is the Closest Moon to Earth since 1948

 

By: NASA Goddard

Originally published on Nov 9, 2016

The moon is a familiar sight, but the days leading up to Monday, Nov. 14, promise a spectacular supermoon show. When a full moon makes its closest pass to Earth in its orbit it appears up to 14 percent bigger and 30 percent brighter, making it a supermoon. This month’s is especially ‘super’ for two reasons: it is the only supermoon this year to be completely full, and it is the closest moon to Earth since 1948. The moon won’t be this super again until 2034!

Pluto in a Minute: How Similar are Pluto and Charon to the Earth and the Moon?

 

By: NASA New Horizons

Originally published on Jul 8, 2015

What’s cool about Pluto? Get a quick peek at the latest science in this daily update from NASA’s New Horizons mission, on track for a flight past Pluto on July 14, 2015.The Pluto-Charon system is a lot more Earth-Mook-like than you’d think. This is Pluto in a Minute.

Let’s start with the similarities between the two planets first. They’re not that similar, but they do share some characteristics. Both Pluto and the Earth has nitrogen-based atmospheres, and both planets are also colored. Pluto has a reddish color, and the Earth, as we know, is green, brown, and predominantly blue.

Both planets also have relatively large moons. Our moon is a quarter of the size of the Earth and Charon is half the size of Pluto. And those two moons are similar as well. Our moon has an extremely tenuous atmosphere; whether or not Charon does have an atmosphere similar to our Moon’s is something New Horizons is going to check out. And both these moons are grey, though for different reasons. Our Moon is grey because of basalt or anorthosite, and Charon is grey from ice. And both these grey surfaces are heavily cratered, at least, we know that our own Moon’s is, though scientists suspect that Charon has its fair share of craters as well.

And, interestingly, both those moons were formed from impact events. Our own Moon was formed from debris after a Mars-sized planet smashed into the early Earth. Similarly, Charon was formed when a Pluto-sized body smashed into a young Pluto.
And one final commonality: both these moons are tidally locked to their home planets, which means they show the same face to the planet at all times.

NASA | A View From The Other Side (The Dark side of the Moon)

 

By: NASA Goddard

Originally published on Feb 4, 2015

A number of people who’ve seen NASA’s annual lunar phase and libration videos have asked what the other side of the Moon looks like, the side that can’t be seen from the Earth. This video answers that question. The imagery was created using Lunar Reconnaissance Orbiter data.

Scientists believe there is an ocean hidden beneath the surface of Jupiter’s moon Europa. NASA-JPL astrobiologist Kevin Hand explains why scientists are so excited about the potential of this ice-covered world to answer one of humanity’s most profound questions.

NASA | Earthrise: The 45th Anniversary

By:  NASA Goddard

In December of 1968, the crew of Apollo 8 became the first people to leave our home planet and travel to another body in space. But as crew members Frank Borman, James Lovell, and William Anders all later recalled, the most important thing they discovered was Earth.

Using photo mosaics and elevation data from Lunar Reconnaissance Orbiter (LRO), this video commemorates the 45th anniversary of Apollo 8’s historic flight by recreating the moment when the crew first saw and photographed the Earth rising from behind the Moon. Narrator Andrew Chaikin, author of A Man on the Moon, sets the scene for a three-minute visualization of the view from both inside and outside the spacecraft accompanied by the onboard audio of the astronauts.

The visualization draws on numerous historical sources, including the actual cloud pattern on Earth from the ESSA-7 satellite and dozens of photographs taken by Apollo 8, and it reveals new, historically significant information about the Earthrise photographs. It has not been widely known, for example, that the spacecraft was rolling when the photos were taken, and that it was this roll that brought the Earth into view. The visualization establishes the precise timing of the roll and, for the first time ever, identifies which window each photograph was taken from.

The key to the new work is a set of vertical stereo photographs taken by a camera mounted in the Command Module’s rendezvous window and pointing straight down onto the lunar surface. It automatically photographed the surface every 20 seconds. By registering each photograph to a model of the terrain based on LRO data, the orientation of the spacecraft can be precisely determined.

Full Moon Silhouettes. Full Moon Rising. Mount Victoria in Wellington ( New Zealand )

Originally Published on Jan 30, 2013. By Mark Gee

http://markg.com.au/2013/01/full-moon…
This is my “Full Moon Silhouettes” short, as seen originally on Vimeo. It is a real time video of the moon rising over the Mount Victoria Lookout in Wellington, New Zealand. People had gathered up there this night to get the best view possible of the moon rising. I captured the video from 2.1km away on the other side of the city. It’s something that I’ve been wanting to photograph for a long time now, and a lot of planning and failed attempts had taken place. Finally, during moon rise on the 28th January 2013, everything fell into place and I got my footage.

The video is as it came off the memory card and there has been no manipulation whatsoever. Technically it was quite a challenge to get the final result. I shot it on a Canon ID MkIV in video mode with a Canon EF 500mm f/4L and a Canon 2x extender II, giving me the equivalent focal length of 1300mm.
