2nd in a series of posts inspired by Elite Dangerous, a space video-game that I’ve been playing; full of images, cool astronomy & science facts, and associated sci-fi & pop culture trivia.
Sol Region Sight-Seeing Tour – Stop #2:
Pollux / β Geminorum
Pollux is 34 lightyears from Sol, and the closest giant star to our sun. Pollux is 18 ly from Stop 1 on our tour, it’s “twin” Castor. Pollux is the 18th brightest star as seen from Earth (including the Sun) and the brightest star in constellation Gemini. Pollux is an orange-hued “evolved giant” star in a special spectral class, called Class KO-III. Earlier in its life it would have been a Class A (hot white or blue/white dwarf star), but Pollux has exhausted the hydrogen in its core, and expanded and cooled as a result. As such the star has moved off the line of main sequence or “adult” stars and entered it’s old age “giant” phase, and is estimated to be about 724 million years old. It is about two times the mass, and almost NINE times the radius of our Sun. Continue reading Sol Region Sight-Seeing Tour #2 – Pollux
The Tour? Why that’s a geeky idea I had to dig up all the fact and fiction about the stars around and including our Sun, known as Sol in science and science fiction. Ostensibly, as a bit of a learning experience while I go about the playing a video-game.
You see, I’ve been playing a “space flight simulator” video game I really love called Elite Dangerous that has excited my long interest in Astronomy. The game is set in the future where humanity has moved out to begin to settle and explore our galaxy. As such the game includes a 1 to 1 online mock-up of our Milky Way Galaxy with as much as we know to be true added to it, and fairly realistic algorithms for what we don’t know, and a lot of fictional future-history and lore added to give it all some drama, and all kinds of different ways to “play” depending on your interests. From exploration, pvp & pve combat, mining, commodity trading, power play politics, passenger liner business, bounty hunting, and much more.
I wanted to explore some of the famous stars we know in our real night skies.
I love these kind of articles that combine my favorite geeky sci fi show with nerdy hard core numbers. Not to spoil it, but the answer is, “Yes, it’s entirely feasible she could.” I had actually questioned the physics of this scene, but this guy does the math and I believe his results. Check it out. Great stuff!
I’ve been reading Red Mars by Kim Stanley Robinson. I’m about 1/3 of the way through it and so far it gets about 3.5 out of 5 stars. I’ve always been fascinated by Mars and have fantasized about visiting it.
Anyway, reading the book got me interested in looking up some good images of Mars so I could “see” where some of the events of the book take place. Continue reading Living Mars
“If scientific reasoning were limited to the logical processes of arithmetic, we should not get very far in our understanding of the physical world. One might as well attempt to grasp the game of poker entirely by the use of the mathematics of probability.” — Vannevar Bush (engineer, inventor, science administrator 1890-1974)
We all know that the answer to Life, The Universe, and Everything is 42. If only we knew what The Question actually was this answer might make sense. While this cool website won’t provide you with The Question of the Universe, it will show you exactly “how vastly hugely mindbogglingly big it is.”
Needless to say this Scale of the Universe website is VERY cool! Plan to browse awhile. And “Don’t Panic!”. Peril-sensitive glasses are NOT required to to view safely.
