Milky Way Galaxy

Yes. The Milky Way is the name we give to our galaxy. All the stars we can see are in our own galaxy, so all the constellations we see are part of the Milky Way. At certain parts of the night sky we can see a dusty pattern through the sky which most people call the Milky Way. However, it is just part of it, and every star we can see is part of the Milky Way too, including the Sun and all the planets and of course Earth.

It is not. On the other hand, the Milky way sun creates the halo. When you see milky from above, it is diffucult to notice the halo. If you shift or rotate the view, you can see that the Milky way halo is a cicurference with the sun in the center and it covers all planets circling this sun.

The term galactic halo is used to denote an extended, roughly spherical component of a galaxy, which extends beyond the main, visible component. It can refer to any of several distinct components which share these properties

The milky way is approximately 100,000 light years across and 1,000 ly thick at the thickest part.

1 mile = 63,360 inches

1 ly = 9.461×1015 miles.

So 1,000 ly = 9.461 x 1018 miles = 5.99x1023 inches thick.

100,000 ly = 9.461 x 1020 miles = 5.99x1025 inches across.

The Milky Way stretches through various constellations, so it does not belong to any one of them.

No. The Milky Way galaxy is just one of billions of galaxies in the Universe. Just like there are billions of planets in the Milky Way Galaxy, there are also comparable numbers of planets in other galaxies.

The Milky Way is part of the Local Group, which is part of the Virgo Supercluster.

Yes, as far as we can tell (it is difficult to see when you are in it) the Milky Way is a barred spiral galaxy with at least four spiral arms. It is a disk of about 400 billion stars 1,000 light years thick with a diameter of about 100,000 light years.

The bar in the center of the spiral rotates every 15 to 18 million years, while the spiral arm pattern (these are a pressure wave effect) rotates every 50 million years. Our sun which is 26,000 light-years form the center, rotates about the galactic core (the galactic center harbors a compact object of very large mass, strongly suspected to be a supermassive black hole ) once every 220 million years.

There are all kinds of stars in our Milky Way galaxy. Our sun is a G2V type star. There are red giants, blue giants, white dwarfs, red dwarfs, brown dwarfs, and probably even black dwarfs (burned out suns), neutron stars, and pulsars. There are also herbig-haro objects, a peculiar type of star that emits collimated bipolar jets of radiation.

By the current best estimates, no. The sun will likely enter its red giant stage in about 5 billion years. The collision with the Andromeda galaxy is expected to occur in 3 to 4 billion years.

No. We are in the outer portion of the Milky way about 3/4 of the way to the edge. The center of the Milky Way could not sustain life.

A disk has multiple speeds - at it's perfect center it's standing still (as you approach the center the speed gets smaller and smaller as you approach 0) At the outer rim (where our star Sol and it's attending planets) are rotating around the galaxy center at about 500,000 mph, ~0.0007% of the speed of light.

Probably the furthest "named" object would be Sagittarius A a supernova remnant at about 30,000 light years.

The furthest object would be on the other side of the Galaxy at about 75,000 light years and could be a star, a nebula or just a grain of dust.

The Milky Way contains somewhere around 200 billion stars. These stars account for about 20% of the visible mass of the galaxy, the other 80% being interstellar gas.

However, most of the matter in our galaxy is of a form we have not yet identified, and we call it "dark matter." We don't know what it is, but we can measure its effect on the rotation rate of the stars, and we can calculate the distribution of the dark matter.

Estimated at around 25-30 thousand Light Years away

The milky way galaxy is a barred spiral shaped galaxy.

Aside from occupying space, our galaxy also rotates. It takes about 220 million years for it to spin once.

We have thoroughly explored our own planet Earth, have imaged many of the other planets from orbit, and we have no clue about any of the other planets that might be orbiting any of the TRILLION other stars in the Milky Way. Your question would be like looking closely at a single spoonful of sand in your sandbox and wondering about the biggest grain of sand on any of the world's beaches.

The biggest mountain that we know of is on Mars, Olympus Mons. We know little enough about Venus, just some radar surveys; details about the outer planets are unknown to us. We know nothing about anything outside our solar system, but it is statistically certain that taller mountains exist elsewhere in the galaxy.

Depending on what galaxy you are tlaking about -.-

Technically, you cannot take a picture of our own galaxy from outside, as the camera would have to travel tens of thousands of light-years out of the galaxy to do so. However, if you're on Earth, you see a large stream of countless stars in the night sky. That is part of the milky way galaxy. The "pictures" you see in the newspapers are just artists' impressions of how the Milky Way would look, not the actually appearance.

It would look dark and thin on the edges, and getting oh so thicker and brighter near the center.

An estimation of the absolute magnitude is −20.9.

See related question.

The galaxy cluster that contains the Milky Way is called the Local Group.

The Milky Way Galaxy is a galaxy ALL the time...
