CosmicRamiA while back (around seven months ago) I posted an image of ISS (first image), but captured FROM ABOVE (higher orbit). This is the work of Aussie company HEO!This type of work is really fascinating as things (like satellites) are all moving at high velocities up there (28,000 km/h) - so other things (like other satellites or space stations) zip past quickly. You would then need to 'de-zip' the object to make a crisp clear image.Well, they've done it again.This time, imaging the Chinese Space Station (second image) from a distance of 83 kilometres (resolution of 0.17 m/px) 🤯This is really cool stuff. I promise.📸 BlackSky / HEO<a href="https://aus.social/tags/Space" class="mention hashtag" rel="nofollow noopener" target="_blank">#Space</a> <a href="https://aus.social/tags/EarthObservation" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthObservation</a> <a href="https://aus.social/tags/SpaceStation" class="mention hashtag" rel="nofollow noopener" target="_blank">#SpaceStation</a> <a href="https://aus.social/tags/Astrodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#Astrodon</a>

ArvitZThe Whirlpool Galaxy - Messier 51a + 51b-----------------------Capturing this beautiful all-time favorite target involved taking my big 8" RC out of the city. This time the field work was much more successfull than earlier attempts this year... there was no wind and *only* 1.5 h of setup time.I am glad to have captured 3 h of RGB data before the moonrise. Especially because I had to motivate myself for work the next day.<a href="https://app.astrobin.com/i/i80has" rel="nofollow noopener" translate="no" target="_blank">https://app.astrobin.com/i/i80has</a><a href="https://mastodon.world/tags/astronomy" class="mention hashtag" rel="nofollow noopener" target="_blank">#astronomy</a> <a href="https://mastodon.world/tags/astrodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#astrodon</a> <a href="https://mastodon.world/tags/photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#photography</a> <a href="https://mastodon.world/tags/space" class="mention hashtag" rel="nofollow noopener" target="_blank">#space</a>

CosmicRamiWhooooaaaa! The new <a href="https://aus.social/tags/JWST" class="mention hashtag" rel="nofollow noopener" target="_blank">#JWST</a> image is so good! So much physics going on — physics Einstein himself thought about!This is called an Einstein Ring. When a massive foreground galaxy (in this case, an elliptical galaxy) warps the space-time around it, light from behind it bends in our direction.The JWST caught this fantastic example, where the background spiral galaxy is getting warped into our view. It appears as a ring, but we can see its structures like its spiral arms, gas features and star clusters. Incredible science happening here! 📸 ESA/Webb/NASA/CSA/G.
