Gemini and "surrounding"
Gemini truly starts where Taurus ended - with Orion. The famous star Betelgeuse is at 3°45’ sid. Gemini. At 5 degrees on the ecliptic we find the "anti GEN" point (Galactic Equatorial Nodes).
Pollux and Castor are the name-giving "Twin Stars" - they are a little north of the ecliptic in the later part of the Sign/constellation - it's like they stand with their feet on the galactic equator and the heads near Cancer.
Traditionally Gemini is of mutable air and therefore about the logic mind. Gemini is about communication and commerce but also collaboration and brings attributes like being very social, fast, curious and openness to the New, whatever that may be.... Pollux and Castor (the Twins) are of two realms. - Pollux is the one connected to the "higher and spiritual realms" and Castor managing the earthly day to day life - they work together, hand in hand, combining the two realms, anchoring the energies.
Planetary points in Gemini: (2020 heliocentric data)
Northnode: Jupiter 15°, Pluto 25°, Saturn 28°
Perihelion: Earth 15-18° , Saturn 5°
The "anti" Galactic Equatorial Node: It's an axis - it's the two points on the ecliptic, where the Galactic Equator crosses the ecliptic, which currently happens at around 5 degrees of Gemini and Sagittarius. There are many cycles that are affecting Earth, the Galaxy and the Universe - the Mayan calendar speaks of them but also many other traditions and mythologies, we just started to re-discover them again. At the moment the moment this GEN axis is emphasized on as the precession cross is over-laying it (the solstices parallel and equinoxes square).
Astrologically these points are important areas for the Human evolution as well as that of Earth, the solar system and the probably the whole galaxy as it shows our "connection" and "collaboration" in much wider sense - we can see that in the so called "ages" and their shifts but also the whole precessional cycle...
Orion: As already mentioned on the "Taurus page", Orion can be seen quite differently throughout the ages and mythologies. From the mother Spider, the Hunter and Protector to the souls travel gate and modern star gate there is all available.... I see Orion as a passage-Keeper or Guardian - the ongoing process of integrating both, the physical and the mental/spiritual. On the Taurus side more the physical, on the Gemini side more the mental - but connected by the Orion's Belt - which can, when consciousness rises, become a gate as well....
Sirius of Canis Major: Sirius is the brightest star in the sky and has been used for seasonal detection, navigation and various other practical uses throughout the earlier part of this cycle. There are many different mythologies and tales around this beautiful Star. In Egypt the goddess Isis is "assigned" to Sirius but when "digging deeper", there are also the beliefs, that our ancestors were extraterrestrials and some from the Sirius-system (when looking at ancient paintings, carvings and texts there is no other interpretation and I think there was for sure contact!!). Sirius brings teaching through life lessons and high mental abilities combined with a sense of responsibility that sometimes may take the couleur of control....
Nebula IC near Castor of Gemini
This oddly colorful nebula is the supernova remnant IC 443 as seen by NASA's Wide-field Infrared survey Explorer, or WISE. Also known as the Jellyfish nebula, IC 443 is particularly interesting because it provides a look into how stellar explosions interact with their environment. IC 443 can be found near the star Eta Geminorum, which lies near Castor, one of the twins in the constellation Gemini.
Just like human beings, stars have a life cycle -- they are born, mature and eventually die/transform. The manner in which stars die depends on their mass. Stars with mass similar to the sun typically become planetary nebulae at the end of their lives, whereas stars with many times the sun's mass explode as supernovae. IC 443 is the remains of a star that went supernova somewhere between 5,000 and 10,000 years ago. You can read more here:
