The beauty of our little planet , in our little insignificant corner of the Milky Way is all the more beautiful because its our HOME.
Earthrise is a photograph of the Earth taken by astronaut William Anders in 1968, during the Apollo 8 mission. Nature photographer Galen Rowell declared it “the most influential environmental photograph ever taken.” This had been preceded by the crude 1966 black-and-white raster earthrise image taken by the Lunar
Planet Earth seen from space (Full HD 1080p) ORIGINAL
Earthrise is the name given to NASA image AS8-14-2383, taken by astronaut William Anders during the Apollo 8 mission, the first manned voyage to orbit the Moon.
Initially, before Anders found a suitable 70 mm color film, mission commander Frank Borman took a black-and-white photograph of the scene, with the Earth’s terminator touching the horizon. The land mass position and cloud patterns in this image are the same as those of the color photograph entitled Earthrise.
The photograph was taken from lunar orbit on December 24, 1968, with a highly modified Hasselblad 500 EL with an electric drive. The camera had a simple sighting ring rather than the standard reflex viewfinder and was loaded with a 70 mm film magazine containing custom Ektachrome film developed by Kodak. An audio recording of the event is available with transcription which allows the event to be followed closely – excerpt:
Anders: Oh my God! Look at that picture over there! There’s the Earth coming up. Wow, is that pretty.
Borman: Hey, don’t take that, it’s not scheduled. (joking)
Anders: (laughs) You got a color film, Jim?
Hand me that roll of color quick, would you…
Lovell: Oh man, that’s great!
There were many images taken at that point. The mission audio tape establishes several photographs were taken, on Borman’s orders, with the enthusiastic concurrence of Lovell and Anders. Anders took the first color shot, then Lovell who notes the setting (1/250th of a second at f/11), followed by Anders with another two at varying exposures.
A nearly full-page black and white reproduction of Borman’s image may be viewed on page 164 of his 1988 autobiography, captioned, “One of the most famous pictures in photographic history — taken after I grabbed the camera away from Bill Anders”. Borman was the mission commander and notes (pg. 212) that this is the image “the Postal Service used on a stamp, and few photographs have been more frequently reproduced” [but see above]. The photograph reproduced in the Frank Borman autobiography is not the same image as the Anders photograph; aside from the orientation, the cloud patterns differ.
The stamp issue reproduces the cloud, color, and crater patterns of the Anders picture. Anders is described (pg. 193) by Borman as holding “a masters degree in nuclear engineering”; Anders was thus tasked as “the scientific crew member … also performing the photography duties that would be so important to the Apollo crew who actually landed on the Moon”.
The as-published photograph shows Earth:
- Polar orientation: south to left, north to right (Antarctica at 10 o’clock)
- Equator: center, running westward toward top right-hand corner
- Nightfall terminator crossing the African continent (lightish region to left is Namib Desert, Namibia; to right is Western Sahara/West Africa)
- Rotated clockwise approximately 135° from our typical North/South-Pole-oriented perspective
In Life ‘s 100 Photographs that Changed the World, wilderness photographer Galen Rowell called Earthrise “the most influential environmental photograph ever taken.” Another author called its appearance the beginning of the environmental movement.
In 1969, the U.S. Postal Service issued a stamp (Scott # 1371) commemorating the Apollo 8 flight around the Moon. The stamp featured a detail (in color) of the Earthrise photograph, and the words, “In the beginning God…”, recalling the Apollo 8 Genesis reading.
On April 6, 2008 (Japan Standard Time), the first 1080p high-definition Earthrise video was captured, both a full Earthrise and Earthset video, by the JAXA lunar orbiter mission, SELENE (better known in Japan by its nickname Kaguya). After successfully orbiting the Moon for 1 year and 8 months, it was crashed intentionally onto the lunar surface at 18:25 UTC on June 10, 2009.
2013 simulation video
In 2013, in commemoration of the 45th anniversary of the Apollo 8 mission, NASA issued a video about the taking of the photograph. This computer-generated visualization used data from the Lunar Reconnaissance Orbiter spacecraft, which had provided detailed images of the lunar surface that could be matched with those taken every 20 seconds by an automatic camera on Apollo 8. The resulting video, re-creating what the astronauts would have seen, was synchronized with the recording of the crew’s conversation as they became the first humans to witness an Earthrise. The video included explanatory narration written and read by Andrew Chaikin.
Potential earthrises as seen from the Moon’s surface
An earthrise that might be witnessed from the surface of the Moon would be quite unlike moonrises on Earth. Because the Moon is tidally locked with the Earth, one side of the Moon always faces toward Earth. Interpretation of this fact would lead one to believe that the Earth’s position is fixed on the lunar sky and no earthrises can occur, however, the Moon librates slightly, which causes the Earth to draw a Lissajous figure on the sky. This figure fits inside a rectangle 15°48′ wide and 13°20′ high (in angular dimensions), while the angular diameter of the Earth as seen from Moon is only about 2°. This means that earthrises are visible near the edge of the Earth-observable surface of the Moon (about 20% of the surface). Since a full libration cycle takes about 27 days, earthrises are very slow, and it takes about 48 hours for Earth to clear its diameter. During the course of the month-long lunar orbit, an observer would additionally witness a succession of “Earth phases”, much like the lunar phases seen from Earth. That is what accounts for the half-illuminated globe seen in the photograph.
And now for a bit of me pondering the age old question , Are we alone? Just for fun mind you!
I’m no expert, but I sincerely believe that we are not alone in the universe .
- Come on – between 100 billion – 400 billion stars in our galaxy ( Milky Way )
- and over one 100 billion galaxies out there!
- And I’ve not even touched on the multiverse
- The numbers alone our mind boggling
I just find it inconceivable that out of these vast numbers our solar system is the only place that life took hold and evolved into the beautiful earth we know today.
I’m no Expert . But I assume that every thing that was needed to create the conditions for life on earth were no doubt abundant throughout space during the birth and evolution of space and the birth of Galaxies .
If the elements for life found their way to out tiny corner of the Milky Way , why not elsewhere?
I’m not saying that life is abundant throughout our galaxy and the billions of other galaxies out there , but surely the same elements that kick started life on earth must have travelled through space and found a home on other worlds out there.
Unfortunately due to the vast distances to these other worlds and galaxies we will never be able to travel to them or indeed send space ships and probes to unlock their secrets.
Our own Milky Way is so huge that even at the speed of light it would take 100,000 years to travel across it!
I expect that most life forms out there are single cell and far below the complex life forms that are found on earth.
But what if there are other more advance civilizations out there? No matter how advance they may be they will still be faced with the vast distances of space and time and would face the same frustrations as us , being stuck in their tiny corner of their galaxies and asking themselves the age of question”
“ARE WE ALONE”
The mind boggle….
The Drake Equation
The Drake Equation is used to estimate the number of communicating civilizations in the cosmos, or more simply put, the odds of finding intelligent life in the universe. N = The number of civilizations in the Milky Way galaxy whose electromagnetic emissions are detectable
a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km (nearly 6 million million miles).
