@wonderofscience That is such a wonderful image. Much more realistic than most of the images from the moon perspective. 👍

This is one of the coolest things I've ever seen
My jaw dropped into the earth's crust
mat@wonderofscience
That is stunning and yes jaw dropping. Can I share this..? On fb for instance?

Alan@wonderofscience is there artificial interpolation between frames? it is incredibly smooth.
Hugh Young-BishNo. They just shot more frames than you think.

Chris White@wonderofscience I did expect to see some earth rotation, mind it depends on the time span I suppose.
Jon_Jon@wonderofscience Wow. Feels like being there.
Sudhir@wonderofscience Beautiful👍🏼❤️😊🙏

@wonderofscience Wow -- stunning.
janj@wonderofscience why are the angles of moon-shadows and neither clouds nor shadow of earth changing? where is the report fake news button here?
@jfriedensreich @wonderofscience
Because the moon only rotates once a month and the whole time elapsed is only minutes. Cloud movement on earth visible by naked eye from the moon would take days.
Stop being so ready to cry "Conspiracy!" based on ignorance.
Ro Gutiérrez Abréu ✨️@wonderofscience why does this remind me of a Monty Python animation? 😀 We live in amazing times that such a view is possible.
lazybird@wonderofscience Am i the only one who thought there’s something wrong with this image when scrolling down their timeline? 😅
Sue@wonderofscience
Stunning. Thank you for posting this

@wonderofscience
What is the actual frame rate? The "setting" is entirely due to the satellite's orbiting of the moon, right?
(Kayuga/Selene's lunar orbital period was 118 minutes, or 20 seconds per degree, so I'm guessing a frame rate of 1/a few seconds - far too fast to capture any cloud movement on earth.)
And what a difference an atmosphere makes!
The earth subtends about 2° as seen from the moon, so at 20 seconds per degree it takes 40 seconds to "set" (from touching to hidden).
In the video it takes about 5 seconds, so the speed is x8. If the video is 16 frames/sec, it was shot at 2 frames/sec.

Bowman Klinkenberg@wonderofscience I'm a sighted person and just learning about accessibility through alt text. I'll be using excellent narrative descriptions like this one as an example. Thanks!

Neil1808@wonderofscience When residents of the moon see the Earth setting do they call it an Earthset?
Spencer W Hunter@Neil1808 @wonderofscience
Unless they lived near the limb, the Earth would never set (or, on the far side, rise).

Justine S. Harrison@wonderofscience this is cool
@Lee_in_Iowa@wonderofscience Boy, our Moon sure has been kicked around out there! I wonder how much similar damage the Earth has that we can’t see under all the water and foliage.
Dr. Eric J. Fielding, PhD@Lee_in_Iowa @wonderofscience The Earth has much fewer craters than the Moon, because erosion and tectonic processes replace the surface over time. The Moon has all the craters of the past 4.5 billion years but most of the Earth surface is less than 0.2 billion or 200 million years old. Earth atmosphere also stops many incoming meteors.
@wonderofscience Whoa—read the alt text!

@wonderofscience How come there is black space around Earth - there are no stars visible?
Whenever I look up I can see milliones of stars; so I am qurious why there is only black space here …

@Pablito I believe its because of the brightness coming off the moon and earth. The camera sensor is calibrated for their brightness, and since stars are quite faint in comparison, it just looks dark.
@ZarrPlays Thank you, I did not realize the reflected light from our Earth is so strong.
Channel84(TJ)@wonderofscience so nice to be able to see things like this without hundreds of comments saying ‘flat earth’ and ‘cgi’.
