Where are we in the Galaxy?

[Jedi Master Kael Caivera]

well technically there are two answers... seeing as how the Milky Way is a spiral galaxy we are on a spiral arm but we are also in the outer rim of the galaxy

[Shara]

We're in the Milky way. That's all I know.

And guys, I bet the candy bar is named after the Galaxy. Not the other way around...

The speed and distance of the Sun can be used to find the orbital period of the Sun, about 240 million years. The mass of material inside the Sun’s orbit, found from Newton’s form of Kepler’s third law, is 100 billion solar masses. * in other words we only go around the core every 240 million years*
The observed flat rotation curve of the Galaxy is drastically different from what is expected from a simple Keplerian motion. This implies that the mass of the Galaxy increases with increasing distance and is probably many times more than the mass estimated from the visible part of the Galaxy. This invisible mass, most of which appears to be in the galactic corona, is called dark matter and its true identity is yet unknown.
Young objects are used as spiral tracers to map the spiral arm segments near the Sun. They include O and B associations young open clusters, emission nebulae (HII regions), and higher-mass variable stars.



Now, for extra credit, who knows what Galaxy CLUSTER we are part of?

LOL, yeah boring I know,,

Yes, we are a outer rim/ spiral arm/ potentially binary system.. We are also in the outer edge of the Libra Galaxy Cluster

sorta blows your mind..our galaxy is a very very very small galaxy, features several million nebulas, several billion suns, trillions of planets,,,

part of a galaxy cluster that contains billions of galaxies, most of them larger than ours by far

and there are billions of galaxy clusters,, that we can SEE,, there is a limit to how far radioscope can go, but wow,, just really really amazing

GOD DAMNIT ADENA


I spend 15 mins looking for the freaking name and you post that

[Renthous Vacvar]

I love Astronomy. That's my other hobby after baseball. I can spend hours outside looking at the starts and wondering what life is like on other planets

[Halan]

Cough stolen from a movie cough

[Renthous Vacvar]

no I'm being completely honest Matt. And besides I have no clue what movie you're talking about

[Halan]

I swear thats a line from a movie but alas I cannie remember...

[Renthous Vacvar]

still no clue but oh well

Possibly 'Contact'?

[Joseph Gray]

We're in one of the Spiral Arms, lasted I checked.

thats as simple english as it gets dear really, that is fourth grade level comprehention at most..or atleast was when I was that age...have the schools gone to hell THAT badly? I REALLY need to get into teaching

basiacly, we are far out in the unfassionable end of the galaxy, back water, far away from the middle...our solor system rotates around the center every 200 million years or so, the fact that our galaxy is flat suggests that darkmatter *which makes up the majority of the compounds* exserts its own mass
