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!

There are between 200 and 400 billion stars in the Milky Way, mostly spread out in a spiral disk surrounding a dense central region. Vast clouds of gas and dust called nebulae occupy much of the space between these stars, called the interstellar medium. There may also be debris and planetary objects…

"The middle of nothing" actually doesn't make any sense. By saying "middle" you are implying spatial dimensions. Space is something, and nothing is literally nonexistence. So you can't say the Universe is in the middle of "nothing." The Universe isn't in the middle of anything, it is everything. &n…

Measuring Galaxies and Black Holes If you know how far away it is, and the angle that it subtends, you can tell its size. For example, if something is 100 meters away and it fills 10 milliradians, it's 100 * 0.01 = 1 meter across. (A milliradian is 1/1000 of a radian, and a radian is about 57 degree…

Projection of Light Black holes do NOT project light. Hence the name black hole. Their gravity field is so strong that nothing escapes, not even light photons. The only way we know they exist by the bending of the trajectory of photons passing them. Galaxies project light via radiant energy, i.e…

The main difference is that a star emits its own energy, which it converts through nuclear fusion; a planet does not. As a result, you can expect a star to have a surface that's quite a bit hotter than that of a planet. What an object is depends, to a great extent, on its mass; objects up to about 1…
