Let’s let NASA paint the pic­ture for you:

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. [See the orig­i­nal pho­to here.] 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.

This video above is pub­lic domain and can be down­loaded here. In 1972, astro­nauts took anoth­er famous pic­ture of the Earth, known as The Big Blue Mar­ble. You can watch a film (“Overview”) that com­mem­o­rates that pho­to­graph and explores the whole con­cept of see­ing the Earth from afar. And, of course, you should always see the Carl Sagan-nar­rat­ed film, The Pale Blue Dot, too.

So many of the images we see of out­er space are either cold and flat—a plan­et sphere sur­round­ed by scores of pin­point stars against the back­drop of black space—or they’re artists’ ren­der­ings.

The pic­tures fea­tured in The Beau­ty of Space Pho­tog­ra­phy are nei­ther of those. They’re more like con­cep­tu­al art: beau­ti­ful, mys­te­ri­ous, and intrigu­ing.

The video above is the lat­est episode of PBS’s Off Book, a web series that explores new Inter­net cul­ture. In this episode, the pro­duc­ers inter­view three astro­physi­cists, and they are any­thing but the pock­et-pro­tec­tor types. These sci­en­tists are artic­u­late, thought­ful, and pas­sion­ate about space and about pho­tograph­ing what they see through super-pow­er­ful tele­scopes.

Work­ing for dif­fer­ent insti­tu­tions, each sci­en­tist uses pho­tog­ra­phy as a major tool to study space. The images have func­tion­al val­ue of course, to assist with mea­sur­ing and doc­u­ment­ing find­ings. But there’s no deny­ing their beau­ty. Astro­physics also touch­es on philo­soph­i­cal ques­tions, so the pic­tures trig­ger a sense of awe that bor­ders on the exis­ten­tial.

The blue and pink swirls of cloud dust and deep spi­ral-shaped galax­ies in these pic­tures are breath­tak­ing because, as astro­physi­cist Emi­ly Rice says, we know what they are and yet they are unfath­omable.

The images are of such high qual­i­ty that they con­vey some of the depth and grandeur of space. The pic­tures seem to con­tain the unbe­liev­able immen­si­ty and allow us to focus in on just a small, beau­ti­ful piece of what is all around out there.

But that’s just part of the fun of this short video. Lis­ten­ing to the sci­en­tists talk about their work is like hav­ing an expert guide you through the uni­verse, a docent who’s excit­ed and edu­cat­ed about things that none of us can tru­ly com­pre­hend even as we gape at their beau­ty.

The oth­er sci­en­tists fea­tured in this short are David Hogg (NYU) and Zolt Lev­ay (Space Tele­scope Sci­ence Insti­tute).
