Galaxies
Galaxies are large systems of stars and interstellar matter, and they contain billions of stars. Our own galaxy, the Milky Way, has 200 to 400 billion stars, and there are over one billion known galaxies. Questions that have to do with galaxies in general and specific galaxies are perfect for this category!

How long does it take for light from Schedar to earth?
If you mean "How long does it take for light from Schedar to reach Earth?", then just use the formula: Distance equals speed times time, or more easily look up the distance in terms of lightyears. Wikipedia gives Schedar as being 228 LY's away...or it will take 228 years for the light to reach Earth.
Is galaxy pegasis stronger then ldrago destroy?
To be exact,i think the the match for that is meteo ldrago.But,ldrago destroy is very powerful and won't come out until next year,maybe as early as May or as late as August.Its hard to tell,because when the season of Beyblade Metal 4D is about to start,it will come out.On TV,it'll appear as a big bang pegasus and ldrago destroy pasck.That's what they did for metal masters!So,the point is that ldrago is stronger.Don't believe me?Go at it with big bang pegasus or search for more answers at other sites.There you have it.
Has anyone been to another galaxy?
no one has been went to another galaxy and they even cant pass the one planet
Well, we're inside the Milky Way galaxy, so obviously it's the closest.
The closest satellite galaxy to us is the Canis Major Dwarf Galaxy at a distance of about 25,000 light years.
Most scientists say that the closest galaxy that isn't a satellite of the Milky Way is Andromeda, about 2 million light years away.
However some argue the Large Magellanic Cloud is a separate galaxy, and not a satellite of our own galaxy. If they are correct then the nearest galaxy is 169,000 light years away.
Are there any galaxies in Gemini?
Gemeni is believed as a zodiac sign. I also think it is one of the moon. If it is a moon there shouldn't be a galaxy in Gemeni
Are there at least 350 billion or more large galaxies in the observable universe?
Yes, because scientists have found hundreds and hundreds of galaxies already and scientists say that there are more galaxies out there that they haven't found!
How many galaxys are there out?
There are an estimated 1011 galaxies in the observable Universe. Please note that the entire Universe is much bigger than that, but it is not known how much bigger. It may, or may not, be infinitely big, in which case there might be infinitely many galaxies.
You can count the stars, bu it is as hopeless as tryin to count all the grains of sand in the Sahara Desert. So in other word youcna count stars but you can't. In our galaxy we have 100 billion stars and there are a 100 billion galaxies, at least.
Is it true that the farther away from Earth a galaxy is the slower it is moving?
incorrect. The farther away from earth a galaxy is, the faster it is moving.
Arcturus (Alpha Boötis) is the brightest star in the constellation Boötes.
Coordinates are 14h 15m 39.7s, +19° 10′ 56

How did merchants raise money to invest in exploration?
Merchants raised money to invest in exploration by holding raffles and contests in parts of Europe. Some merchants set up street markets as well as their established buildings to make extra money for exploration.
How big a box needs to be to hold 7000000000000000000000 pennies?
A United States of America penny has a radius of 9.525mm, and a thickness of 1.55mm.
The volume of a penny is given by pi * 9.5252 * 1.55 = 441.8 mm3
Assuming we melted the pennies down so that no space was wasted, the volume of the box needed to hold them all would be
441.8 * 7 000 000 000 000 000 000 000 = 3.093 x 1024 mm 3
Or, to put it another way, if the box was a cube, each side of the box would have to be about 90 miles long.
Why did they name it the little dipper?
I suspect that once the more obvious asterism of the Big Dipper was named, the nearby and similar group was simply called the Little Dipper.
World cultures did not always agree, (heck, they almost never agreed) on which stars were in which asterisms, or what they represented. The which we call the Big Dipper has variously been The Plow, The Sickle, The Cart, the Great Bear (hence the constellation of Ursa Major, which is the Big Dipper plus some other stars) and, in the years following Charlemagne, Charles' Wain (wagon).
Note the distinction between asterisms, which are groups of stars seeming (often to those with strong imaginations) to form animal or other shapes, and constellations, which are tracts of sky, very like countries on a geopolitical map.
Some asterisms are the hearts of constellations, as the Big Dipper is part of Ursa Major, but some are larger. The "Summer Triangle" of Vega, Deneb and Altair takes in parts of three constellations.
What is the relationship between brightness and temperature shown within the main sequence?
As temperature increases the absolute brightness increases
Why the thiele tube is shaped the way it is?
The thiele tube allows convection currents in the oil when it is heated meaning there is fairly uniform distribution of temperature.
What is the mass of eta carinae?
Eta Carinae is a stellar system in the constellation Carina.
It has a mass of about 100 -> 150 Suns. [See related question]
Castor, like all visible stars are within the Milky Way Galaxy - Our galaxy.
