Every galaxy has a unique story to tell. The history of each one is evident in its shape. Scientists divide galaxies up into a handful of appearance-based categories. The Milky Way is what's known as a spiral g
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. ...

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 ...

ruled that a planet is a celestial body that orbits the sun, is massive enough to have a nearly round shape, and has cleared its orbit of debris. Under this designation, Pluto and similar small objects are considered "dwarf planets," although not everyone agrees with the designation. After ...
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 ...
