*Looks behind*
Wow! Look at the size of that Telescope! I wonder how well you can see Alpha Centauri with this?

Forget Alpha Centauri. I can see the Tau Seti System, the Vesuvi System, the Endriarch 41 System (Vulcan), the Cardassia System, and the Bajor System... all perfectly.

Before I study the further areas of space, I would like to get the chance to study some of the closer stars and systems, like Alpha Sentauri, or Canis Major.

Alpha Centauri, also known as Rigil Kentaurus, Rigil Kent, or Toliman.

Constellation: Centaurus
Distance from Sol: 1.34 Parsecs (4.37 Light-years//Approximately 41.34 trillion kilometeres).
Spectral Type: G2V/K2IV
Apparant Magnatude: -0.01/+1.33
Absolute Magnitude: 4.38/5.71

Approximate Age: 4.85 Billion Years Old

Is it a medium size star by any chance?

Its actually two types of classification. You have to remember, Alpha Centauri is a binary star, meaning that there is two stars rather than one.

Alpha Centauri A is a Class G star, just like Sol. Alpha Centauri B is a Class K star, which is slightly smaller. Now Proxima Centauri, which is also known as Alpha Centauri C, is a Class M star, which resembles something of a red dwarf. So technically, Alpha Centauri A or B is NOT the closest star to Sol, it is Alpha Centauri C (or Proxima Centauri) which is 1.3009 parsecs from Sol.

If Proxima Centauri is a Red Dwarf, wouldn't that mean that it has nearly completed its cycle? and if it explodes into a nova (Correct me if I'm wrong), could it possibly have an impact on our Solar System when it does come to the end?

Allow me to present today's Astronomy Class. *Class goes "YAY!*

We now return to the topic of stars and their life cycle. We can simply explain that there are certain types of stars that go nova at the end of their cycle, and others just swell up and shrink into a red dwarf, and continue reducing itself to a white dwarf before fading out. One example of a star that will swell up billions of years from now is the Alpha Centauri binary star and the Sol Star. These two stars will swell up at the end of their life cycles into a red giant. After that phase, it begins to shrink down into a red dwarf, and continuing into the as-before-mentioned white dwarf, thus estingiushing itself.

Larger stars, including Super Giants end their lives in a much more spectacular manner. These stars are only in existance for hundreds of millions of years, rather than the tens of billions their smaller counterparts are. When their life-cycle reaches an end, the star itself becomes dangerously unstable and explodes, in the terminology, it would be best referred as going nova. After the final cycle is complete, the remains of the star, that of the core, becomes a pulsar, rotating billions upon billions times a second, and have an extreme gravity pull. When a star goes nova, it does not alter the gravitational forces of the Universe. Everything else outside the regular star system goes virtually untouched. It is said that there is one star going nova every century.

And lastly, the third life-cycle of a star is a Super Giant, which only lasts a few million years. These stars are so large, their entire life cycle is severely unstable and could go at any moment. At the end of their life cycle, these stars go Super Nova, but the process is so violent, that the explosion itself is said to be so powerful, that it collapses beyond the pulsar, which is also known as a neutron star, into a black hole...

So, to recap...

Nebula > Regular Star > Life Cycle Ends - Iron now used as fuel > Swelling > Shrinking into Red Dwarf > Cooling into White Dwarf = Continues cooling into nothing.

Giant Nebula > Giant Star > Life Cycle Ends - Iron now used as fuel > Instability > Nova = Collapses into Neutron Star (a.k.a. Pulsar).

Super Giant Nebula > Super Giant Star > Constant Instability > Life Cycle Ends - Iron now used as fuel > Extreme instability > Super Nova > Collapses beyond the Neutron Star = Black Hole

Remember class, when a star's life cycle ends, it goes through a series of changes. These changes will only affect what is in a star system and will not have any impact on any star systems.

Thank you for posting this. Unfortunately, I'm a little rusty on my Astronomy. If only there was a way that I could take part within more science at the moment. I don't think I can wait until January to continue learning the subject.

Did joeoflula got banned?

I don't know. You should talk to Zezima if you want to know the answer.

Ok, nobody banned him according to his profile, he is an active user. But for some reason, when he logs on, he can onlt see the banner and it says, "you have been banned from this forum" even though he isnt really. I dont know why that is happening though.

I saw that as well. Could it be because of a problem with the Administrator Panel?

It worked! I win I win I win! :D

Question:If you try to go back into Sega of America forums and they find out that you're you do they instant ban you?

I wouldn't know. It may happen, but I can't give you an exact answer.

Well could you ask them?

First of all, why exactly are you asking this?

Because...

You were banned from the SEGA of America foruma?

GET OUT OF MY MIND!

well, as soon as they found out i was me i was bannned.

You got banned? That sucks. :silent:

he was on for the 5 hours i was on. XD
