Image Description and Details: WR 134 est une étoile variable située à environ 6 000 années-lumière de la Terre dans la constellation du Cygne. WR 134 expulse une partie de ces couches externes qui sont ensuite soufflées par le rayonnement intense et les vents stellaires rapides de l’étoile. L’éjecta est ensuite entré en collision avec la nébuleuse ambiante entourant l’étoile pour former cette espèce de disque (en bleu dans l’image).

Image Description and Details: This is the cometary globule inside IC1396, in Cepheus. It is named "the elephant trunk" due to the similarity with the trunk of this big animal. The globule contains many different protostars and it is shaped by a very energetic star in the center of the nebula complex. In this image I composed 3 different sessions: SHO and L-Extreme images taken with my C11HD from my backyard and RGB images taken with CDK500 from Skygems remote service.

Image Description and Details: M 2-55 is an evolved rarely-imaged planetary nebula in the constellation Cepheus. It was first discovered and identified by the German-American astronomer Rudolph Minkowski on photographic plates at Mount Wilson in 1947. The plates were taken by W.C. Miller with a 10" f/5.2 refractor.
IM 2-55 possesses two sets of bipolar lobes.
It was only in 2020 that a team of Chinese professional astronomers detected an arc of material running from the SE to the SSW. (Chih-Hao Hsia et. al, March 13th 2020, “Discovery of Extended Structures around Two Evolved Planetary Nebulae M 2-55 and Abell 2”). They concluded that this arc was furnishing strong evidence for an interaction of the expanding nebula of \m 2-55 with its surrounding interstellar material. The presence of fragmentation in the arc may be the result of a phenomenon known as Rayleigh-Taylor (RT) instabilities.

This mesmerizing animation captures the celestial ballet between Jupiter, the largest planet in our solar system, and its volcanic moon, Io. In this GIF, Jupiter's massive gaseous sphere slowly rotates, revealing its intricate cloud bands and swirling storms, while Io, the innermost of Jupiter's Galilean moons, orbits gracefully in close proximity. This dynamic display showcases the intricate interplay of gravitational forces and celestial mechanics, offering a vivid glimpse into the captivating dance of celestial bodies in the cosmos.
