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. <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>

Over the years the average number of days in a year has ranged from 372 to 490 days. The rotational speed has been slowing. over time. Atomic clocks are better able to track time and so an extra second is sometimes added- important for GPS. But since 2020 Earth has been speeding up. <a href="https://www.iflscience.com/nobody-expected-this-earths-rotation-will-speed-up-tomorrow-bucking-the-downward-trend-79905" rel="nofollow noopener" translate="no" target="_blank">https://www.iflscience.com/nobody-expected-this-earths-rotation-will-speed-up-tomorrow-bucking-the-downward-trend-79905</a>

Mikko TuomiStudies from recent years have reached different conclusions regarding how frequently super-Earths are accompanied by long period giant <a href="https://scicomm.xyz/tags/planets" class="mention hashtag" rel="nofollow noopener" target="_blank">#planets</a> and vice versa.This relation has been predicted to be mass dependent by <a href="https://scicomm.xyz/tags/planet" class="mention hashtag" rel="nofollow noopener" target="_blank">#planet</a> formation models.Accordingto a new paper, cold Jupiters are six times more massive when not in company of an inner super-Earth, while super-Earths are not significantly more massive while in company of an outer giant planet.There is also an occurrence enhancement for Saturn-mass planets while in presence of a super-Earth by a factor of 4, and for super-Earths in presence of Saturns by the same factor.This positive correlation disappears for super-Jupiters.<a href="https://scicomm.xyz/tags/astronomy" class="mention hashtag" rel="nofollow noopener" target="_blank">#astronomy</a> <a href="https://scicomm.xyz/tags/exoplanets" class="mention hashtag" rel="nofollow noopener" target="_blank">#exoplanets</a> <a href="https://astrobiology.com/2025/06/saturns-but-not-super-jupiters-occur-more-frequently-in-the-presence-of-inner-super-earths.html" rel="nofollow noopener" translate="no" target="_blank">https://astrobiology.com/2025/06/saturns-but-not-super-jupiters-occur-more-frequently-in-the-presence-of-inner-super-earths.html</a>

Mikko TuomiIdentifying the formation period of planetary systems, such as our solar system, could be the beginning of the journey to discover the origin of life.The key to this is the unique substructures found in protoplanetary disks—the sites of <a href="https://scicomm.xyz/tags/planet" class="mention hashtag" rel="nofollow noopener" target="_blank">#planet</a> formation.A protoplanetary disk is composed of low-temperature molecular gas and dust, surrounding a <a href="https://scicomm.xyz/tags/protostar" class="mention hashtag" rel="nofollow noopener" target="_blank">#protostar</a>.If a planet exists in the disk, its <a href="https://scicomm.xyz/tags/gravity" class="mention hashtag" rel="nofollow noopener" target="_blank">#gravity</a> will gather or eject materials within the disk, forming characteristic substructures such as rings or spirals. In other words, various disk substructures can be interpreted as "messages" from the forming <a href="https://scicomm.xyz/tags/planets" class="mention hashtag" rel="nofollow noopener" target="_blank">#planets</a>.<a href="https://scicomm.xyz/tags/astronomy" class="mention hashtag" rel="nofollow noopener" target="_blank">#astronomy</a> <a href="https://scicomm.xyz/tags/exoplanets" class="mention hashtag" rel="nofollow noopener" target="_blank">#exoplanets</a> <a href="https://phys.org/news/2025-06-super-resolution-imaging-reveals-planet.html" rel="nofollow noopener" translate="no" target="_blank">https://phys.org/news/2025-06-super-resolution-imaging-reveals-planet.html</a>
