It's Sega Saturn #Homebrew Week here at SHIRO! We're highlighting all the great fan-made projects over the years starting with the earliest ones: SegaXtreme's C4 competitions in 2003 to 2007!

If you've got a homebrew project in the works, you should enter it into the SegaXtreme SEGA Saturn 30th Anniversary Game Competition! But there's not much time left before the deadline April 11. Check out the competition's thread: segaxtreme.net/threads/sega-sa

#PhotoOfTheDay: #Saturn by #JWST

On June 25, 2023, NASA’s James Webb Space Telescope turned to famed ringed world Saturn for its first near-infrared observations of the planet.

Saturn itself appears extremely dark at this infrared wavelength observed by the telescope, as methane gas absorbs almost all of the sunlight falling on the atmosphere. However, the icy rings stay relatively bright, leading to the unusual appearance of Saturn in the Webb image.

Here is an image of Saturn with its rings seen edge-on by Hubble on Aug 6, 1995. The rings appear as a thin gray line. The thicker darker line below it and across Saturn is the shadow of the rings on Saturn's cloud-tops, caused by the Sun which was above the ring plane.

The 2nd image was taken a few months later on Nov 17, 1995. The tilted ring is now visible but is still dull gray in color.

[top] - This is a NASA Hubble Space Telescope snapshot of Saturn with its rings barely visible. Normally, astronomers see Saturn with its rings tilted. Earth was almost in the plane of Saturn's rings, thus the rings appear edge-on. In this view, Saturn's largest moon, Titan, is casting a shadow on Saturn. Titan's atmosphere is a dark brown haze. The other moons appear white because of their bright, icy surfaces. Four moons - from left to right, Mimas, Tethys, Janus, and Enceladus - are clustered around the edge of Saturn's rings on the right. Two other moons appear in front of the ring plane. Prometheus is on the right edge; Pandora, on the left. The rings also are casting a shadow on Saturn because the Sun was above the ring plane. [bottom] - This photograph shows Saturn with its rings slightly tilted. The moon called Dione, on the lower right, is casting a long, thin shadow across the whole ring system due to the setting Sun on the ring plane. The moon on the upper left of Saturn is Tethys. Astronomers also are studying the unusual appearance of Saturn's rings. The bottom image displays a faint, narrow ring, the F-ring just outside the main ring, which normally is invisible from Earth. Close to the edge of Saturn's disk, the front section of rings seem brighter and more yellow than the back due to the additional lumination by yellowish Saturn. The color images were assembled from separate exposures taken Aug 6 (top) and Nov 17 (bottom), 1995 with the Wide Field Camera-2.

Today observers from Earth would see the rings of #Saturn exactly from the edge if the Sun weren't in the way: bsky.app/profile/astroroyalsco. An animation: bsky.app/profile/leighfletcher. More: scicomm.xyz/@AkaSci@fosstodon.. And an almost-edge-on view in November: bsky.app/profile/kilroi22.bsky

Bluesky Social · Astronomer Royal for Scotland | Catherine Heymans (@astroroyalscot.bsky.social)It's #Saturn ring-plane crossing day! A once in a 13-15 yr event when Saturn's rings are edge on, as viewed from Earth, making them appear to disappear! I'm so infuriated that the Sun is in the way meaning no-one will see it! 😡 We'll just have to imagine it 😞 👇The last time it was seen in 1995. 🔭🧪

Killarney Provincial Park and the Allan I. Carswell Observatory present the Astronomer in Residence (AIR) program, an astronomy outreach endeavour! This is an exciting chance to share your love of astronomy in the wonderful outdoors of the dark sky site at Killarney Provincial Park. Be a part of live, in-person tours as well as remote events, and share your adventures on the Astronomer in Residence Blog.
Perks: Limited stipends available ($400/week). Be sure to note in your application if this is a limiting factor!
This wonderful image of Saturn was taken by former AIR Robin Metcalfe during her residency.

In Science-Fiction-Filmen weiß man immer, dass man auf einem anderen Planeten ist, wenn am Himmel zwei oder drei Monde zu sehen sind. "Wow! Zwei Monde!" denkt man als Zuschauer.

Aber schon bei "unseren" Saturn sind 274 Monde bekannt! Gerade erst sind 128 dazu gekommen!
