AllanICarswellObservatoryHappy Space Science Saturday! Did you know that today Saturn begins its retrograde motion? Normally, Saturn moves eastward against the background of stars, but during retrograde it appears to pivot and move westward through the constellations. This apparent backward motion isn’t because Saturn actually reverses its orbit, but rather because of Earth’s own motion around the Sun. As Earth passes Saturn in its orbit, our changing perspective makes Saturn appear to move backward in the night sky.<br> <br> <br> <a href="https://pixelfed.social/discover/tags/Orbit?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Orbit</a> <a href="https://pixelfed.social/discover/tags/Retrograde?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Retrograde</a> <a href="https://pixelfed.social/discover/tags/Saturn?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Saturn</a> <a href="https://pixelfed.social/discover/tags/SpaceExploration?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#SpaceExploration</a> <a href="https://pixelfed.social/discover/tags/Space?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Space</a> <a href="https://pixelfed.social/discover/tags/Astronomer?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Astronomer</a> <a href="https://pixelfed.social/discover/tags/Astronomy?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Astronomy</a> <a href="https://pixelfed.social/discover/tags/SpaceScienceSaturday?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#SpaceScienceSaturday</a> <a href="https://pixelfed.social/discover/tags/YorkU?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#YorkU</a> <a href="https://pixelfed.social/discover/tags/Observatory?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Observatory</a> <a href="https://pixelfed.social/discover/tags/AllanICarswellObservatory?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#AllanICarswellObservatory</a> <a href="https://pixelfed.social/discover/tags/Stargazing?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Stargazing</a> <a href="https://pixelfed.social/discover/tags/YorkUniverse?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#YorkUniverse</a> <a href="https://pixelfed.social/discover/tags/Telescope?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Telescope</a> <a href="https://pixelfed.social/discover/tags/Planets?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Planets</a> <a href="https://pixelfed.social/discover/tags/Stars?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Stars</a> <a href="https://pixelfed.social/discover/tags/Science?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Science</a> <a href="https://pixelfed.social/discover/tags/Physics?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Physics</a> <a href="https://pixelfed.social/discover/tags/Toronto?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Toronto</a> <a href="https://pixelfed.social/discover/tags/YorkUObservatory?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#YorkUObservatory</a> <a href="https://pixelfed.social/discover/tags/AICO?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#AICO</a> <a href="https://pixelfed.social/discover/tags/Cosmos?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Cosmos</a> <a href="https://pixelfed.social/discover/tags/LearnAstronomy?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#LearnAstronomy</a> <a href="https://pixelfed.social/discover/tags/SpaceFacts?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#SpaceFacts</a>

A Swarm of New Asteroids, discovered by the Vera C. Rubin Observatory in about 10 hours of observations

rubinobservatory.org/gallery/c

0:00: Introductory animation 0:02: We start with a sprawling, textured field of galaxies scattered across the deep black of space. Rubin’s field of view is overlaid as a plus-shaped grid. A rectangle panel expands from the center right to show the grayscale sequence of the point of light of an asteroid moving left to right across the background. 0:12: Another panel expands from the right to show another asteroid moving left to right. 0:13: Yet another panel expands from the top with another asteroid moving diagonally to the upper right. 0:15: Six more panels with moving asteroids expand, to form a grid of nine. 0:20: Many more panels expand, forming a grid of 36. 0:28: The panels disappear, showing the original field of galaxies. Now, about 1000 teal dots appear on screen, representing Rubin’s discoveries on night 1 of observations. They’re generally moving toward the upper right at a leisurely pace. There are a few dots in purple and yellow, representing other types of Solar System objects. 0:32: More and more dots continue to appear as time progresses from night 1 to night 7, totaling 2104 objects. They’re mostly teal, representing main belt asteroids, but there are a couple dozen purple and yellow dots too. 0:42: The view rotates clockwise by about 45 degrees and zooms out to show the direction of observations and the objects detected from the perspective of Earth, seen in the foreground 0:45: The view continues to zoom out to show a bird’s eye view of the Solar System. Earth’s orbit is a circle inside the donut shape of the main asteroid belt filled with millions of dots. Rubin’s new detections are highlighted using the same colors as before, now seen as a narrow 3D cone shape extending from Earth out into the Solar System toward the top of the video.
rubinobservatory.orgA Swarm of New Asteroids (Video-EN)In about 10 hours of observations, NSF–DOE Vera C. Rubin Observatory discovered 2104 never-before-seen asteroids in our Solar System, including seven near-Earth asteroids (which pose no danger). Annually, about 20,000 asteroids are discovered in total by all other ground and space-based observatories. Rubin Observatory alone will discover millions of new asteroids within the first two years of the Legacy Survey of Space and Time. Rubin will also be the most effective observatory at spotting interstellar objects passing through the Solar System.

The 4 biggest mysteries the new Vera Rubin Observatory could solve

No telescope has basked in the night sky quite like this before. Here's what it could reveal about the universe.

Just two days to go before the public reveal of the first images!

It's also the sort of business that I feel like any state foreign intelligence service ought to be willing to fund. Just in case something they regarded as not being useful to them in space needed to be de-orbited in a responsible and timely manner. I feel like we should try to persuade the band to capitalise on that... 🤪

Regardless, astronomers of the world will be willing to give Space Junk Removal Service a listen ❤️
