Benjamin SimpsonNature is amazing. On Exoplanet 45346 the Spatio Vine formed into a space elevator. I mean, it’s not technically an elevator, because there are no elevators, but it grows on the planet surface and one single huge strong vine grows up and out into space (Jack and the Beanstalk!!) and once there grows a huge heavy knob of weight so that it stays in orbit. It defies logic, and makes no sense, but it is real. Some conjecture that an alien race manufactured/formed/genetically modified the vine, but there is no evidence of a civilization on the planet, so the questions continue.<br> <br> <a href="https://pixelfed.social/discover/tags/scifi?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#scifi</a> <a href="https://pixelfed.social/discover/tags/exoplanet?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#exoplanet</a> <a href="https://pixelfed.social/discover/tags/nature?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#nature</a> <a href="https://pixelfed.social/discover/tags/macro?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#macro</a>

Benjamin SimpsonOn Exoplanet 34476, when the sun is setting, the soft mournful whale-like cries of the Bandi float over the hills and valleys. Because this planet is small, and the gravity is only half that of earth, the Bandi can look like they are floating despite having the mass of an elephant. Sometimes when I think of all the horror and hate of the world, I can look at this photo, remember that moment, that feeling of calm and hope, and I think it might be ok. Not always, but sometimes.<br> <br> <a href="https://pixelfed.social/discover/tags/scifi?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#scifi</a> <a href="https://pixelfed.social/discover/tags/exoplanet?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#exoplanet</a> <a href="https://pixelfed.social/discover/tags/nature?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#nature</a> <a href="https://pixelfed.social/discover/tags/insect?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#insect</a> <a href="https://pixelfed.social/discover/tags/macro?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#macro</a>

Benjamin SimpsonAttacked! <br> Attacked! I say! <br> I was most innocently walking through a forest on Exoplanet 55346 when a giant carnivorous Duchessfoul surprised me! Boy was I shaking!

Benjamin SimpsonThe Octoacme -the land octopus of Exoplanet 26973- builds mounds on the desolate plain. When a nocturnal bird flies too close to the mound, its tentacles strike with speed, agility and precision. But me, after sitting for hours waiting for the moment, stupidly missed it. But then again, the Octoacme also missed the bird, so I don’t feel so bad that the bird is just out of frame.<br> <br> <a href="https://pixelfed.social/discover/tags/nature?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#nature</a> <a href="https://pixelfed.social/discover/tags/apple?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#apple</a> <a href="https://pixelfed.social/discover/tags/scifi?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#scifi</a> <a href="https://pixelfed.social/discover/tags/exoplanet?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#exoplanet</a> <a href="https://pixelfed.social/discover/tags/macro?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#macro</a>
