distances,however,billions of other galaxies are scattered.These galaxies are of many shapes and sizes.The Milky Way Galaxy is shaped like a spiral(螺旋型)disk.Other galaxies have been found to be shaped like spirals,too.In addition,still other galaxies are elliptical or irregular in shape. ...

Our Galaxy, the Milky Way, is a disk of stars about 100,000 light-years across, and about 1,000 light-years thick. ... So, to leave our Galaxy, we would have to travelabout 500 light-years vertically, or about 25,000 light-years away from the galactic centre. What is inside a b...
As an analogy, consider the shape of our galaxy, theMilky Way. We can infer that it is a spiral based on maps of the stars in its spiral arms, but we cannot go outside the galaxy to see this spiral structure firsthand. However, withtelescopes, we can see other spiral galaxies from ...
What color is the Milky Way Galaxy? What do irregular galaxies look like? What distinguishes one type of spiral galaxy from another? What galaxy do we live in? What is the largest star cluster in our galaxy? What is the shape of the Magellanic Clouds?
The Milky Way has three main parts: the core, the disk and the halo. The core isn't spherical; it's elongated into the shape of a bar anywhere from 5,000 to 20,000 light-years long. Up to a quarter of all the stars in the Milky Way reside in the core; the density of stars ...
What is the diameter of the Milky Way? What is our star cluster? What is the shape of the Milky Way Galaxy? What is an equatorial telescope? What are comets from the Oort cloud called? What is planetary astrophysics? What does the redshift of galaxies indicate?
Our Milky Way galaxy is a cannibal. It has grown by consuming other galaxies. Yet, it too, may be destined to collide and merge with an even bigger galaxy: Andromeda. Though galaxy collisions are normal events and NASA suspects this collision is inevitable (in billions of years), new ...
shape into it’s original form. In the Veil Nebula, there are three different colors that represent something. The red is from the glow of hydrogen, blue represents oxygen and lastly, green is from sulfur. The cooler gas is made from a shock collision that later developed into a huge ...
Astronomers have used the James Webb Space Telescope to spy fireworks of light radiating near the supermassive black hole at the center of our Milky Way galaxy. The swirling disk of gas and dust that feeds matter into the black hole, called Sagittarius A*, is responsible for the pyrotechnic ...
