By now, you have seen the Earth image by the #Artemis crew at least a hundred times. In this annotated version, several #optics effects are highlighted. It also shows how fragile planet #Earth is, with a super thin #atmosphere protecting us from the harsh vacuum of space. Let's protect it.

    @pfsmet and we're doing all we can to further thin that protective layer as fast as possible #Artemis #optics #Earth #atmosphere

    @pfsmet so the sun, reflecting off the moon, is bright enough to illuminate Earth like that? I wouldn’t have expected that.

    @pfsmet Why did the author of this image feel the need to rotate the orientation? There's no "up" in space except for "out of the local gravity well".

  • @pfsmet If this is the night side of Earth, lit only by moonlight and presumably photographed in long exposure, shouldn't the city lights be much brighter than this? Or are city lights a lot less visible from orbit than I've been led to believe? 😵‍💫

    @pfsmet to be honest, I have not seen it even once. It's just like all other photos of the Earth. The exciting part is the up close photos from the Moon.

    @pfsmet Nice! I think the brighter reflection in the middle of the image is a reflection from inside the spacecraft, but there is another reflection next to it which is the moon reflecting off the sea

    @pfsmet Every time a picture of the Earth from the Artemis is shown on my timeline, my thoughts are that we should get rid of billionaires, the power of fossil fuel industries and dictators. Our world should not be ruled and ruined by these madmen.

    @pfsmet We are all one single species. Still involved in stupid wars, and even more stupid wars. Why aren’t we solving our real issues? Providing food, shelter, healthcare, and education for everyone. That’s step 1, and we haven’t even accomplished that. Why haven’t we designed an efficient distribution of food. Why healthcare is a privilege and not a right? Why our decisions are not based on science and ethics? Oh, right, superpowers, megacorps, billionaires, and their privileges and greed.

    @pfsmet thank you for the annotations! Even if the image looks spectacular, this view itself is misleading in my eyes, as Earth isn’t so bright at night. The only light sources are at this point stars, the Moon, and light from the sun (in various ways), airglow and artificial light from the ground - I do like this image with a more natural view more: https://www.nasa.gov/image-detail/amf-art002e000193/
