We live in the Milky Way Galaxy, which is a collection of stars, gas, dust, and a supermassive black hole at it's very center. ... There is also a bulge in the middle that consists of mostly old stars.

What is surrounding the Milky Way?
The Milky Way galaxy is in the recycling business. Our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars, according to a NASA-funded study in the journal Nature Astronomy.
What structure is at the center of the Milky Way?
Like most other large galaxies, the Milky Way harbors a supermassive black hole at its center. Known as Sagittarius A* — abbreviated as Sgr A* — this galaxy is about four million times the mass of the Sun.
Is the sun the center of the Milky Way?
The Sun does not lie near the center of our Galaxy . It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way.
What does Milky Way look like?
The Milky Way is a spiral galaxy . ... The spiral arms contain stars, cold molecular gas, glowing star- forming regions and dark dust. The galactic bulge contains mainly older stars, and appears redder than the spiral arms. Since the central bulge is elongated, the Milky Way is classified as a barred spiral galaxy.
What are the main parts of the Milky Way?
This structure can be viewed as consisting of six separate parts: (1) a nucleus, (2) a central bulge, (3) a disk (both a thin and a thick disk) , (4) spiral arms, (5) a spherical component, and (6) a massive halo. Some of these components blend into each other. Three views of the Milky Way Galaxy.
What is in the center of our galaxy?
The centre of the galaxy is a dense and chaotic place, with stars and gas hurtling around the Milky Way's supermassive black hole, Sagittarius A* . It has a mass more than 4 million times the mass of the sun crammed into a diameter just about 30 times the sun's width.
What do astronomers believe exists in the center of nearly every galaxy?
Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas.
Can I see Milky Way today?
You can see the Milky Way all year , no matter where you are in the world. It's visible just so long as the sky is clear and the light pollution is minimal. However, the Milky Way also appears to move in the sky, as the Earth rotates.
How many Milky Ways are there?
All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.
Does the Milky Way move?
The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference. The oldest stars in the Milky Way are nearly as old as the Universe itself and thus probably formed shortly after the Dark Ages of the Big Bang.
What might happen if you got too close to the center of the Milky Way galaxy?
What might happen if you got too close to the center of the Milky Way galaxy? You would be burned up by the galaxy's brightest stars . You would be spun outwards toward the edge of the galaxy. You would be trapped in the gravitational pul of a black hole.
Where is the center of the Milky Way?
The center of the galaxy is located between the Tail of Scorpius and the Teapot of Sagittarius . In a dark sky, you can see clouds of “steam” ascending from the Teapot's spout in this region. Really, they are stars in our Milky Way galaxy.
What is the center of the universe?
There is no centre of the universe ! According to the standard theories of cosmology, the universe started with a “Big Bang” about 14 thousand million years ago and has been expanding ever since. Yet there is no centre to the expansion; it is the same everywhere.
