Scientists have known for some time that the Milky Way Galaxy is not alone in the Universe. In addition to our galaxy being part of theLocal Group– a collection of 54 galaxies and dwarf galaxies – we are also part of the larger formation known as theVirgo Supercluster. So you could say...
Surrounding the galaxy for thousand and thousand of light years is space.At great 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 ...
The first half of the twentieth century saw tremendous advances in the tools of the professional astronomers; telescoper, photographic film and spectroscopic detectors. This allowed our knowledge of the size and composition of the universe to grow in leaps and bounds....
that resemble a pattern. Constellations are areas of the sky where we have broken the sky into parts. All the stars in the constellations are withinthe Milky Way. A galaxy is a large collection of stars containing billions or trillions of stars. Galaxies exist outside our own Milky Way ...
earth seemed to be just a small bit of dust.It is only a small planet,and travels around the sun.The sun together with its planets,travels in the Milky Way,our galaxy.The Milky Way has about thirty billion stars like our sun,and is one of about a hundred million galaxies in the ...
Leo IV is one of more than a dozen ultra-faint dwarf galaxies near the Milky Way. These galaxies are dominated by dark matter, an invisible substance that makes up most of the universe's mass. january-2-2019-galaxy-cluster-sdss-j1004-4112 ...
The star lies near the center of theMilky Way, roughly 9,500light-yearsaway fromEarth. Located within the constellation Scutum, UY Scuti is a hypergiant star. Hypergiants — larger than supergiants and giants — are rare stars that shine very brightly. They lose much of their mass through ...
Male Student: So, the problem’s pretty widespread…Male Professor: It’s basically beyond control, as far as expecting to view the night sky anywhere near a city… I mean, uh, I’ve lived around here my whole life, and I’ve never seen the Milky Way within the city limits—and I ...
There are two possible explanations: 1. There is more stuff (matter) that we don't see with our telescopes. We call this dark matter. 2. Newton's laws and even GR are wrong on the scale of galaxies and everything bigger. This idea is usually called modified gravity (because we need ...
There are some, however, that claim that while the complex barred structure favored by many is possible, that it would make the Milky Way quite different from other barred spiral galaxies that we see and that it might be possible that we instead live in anirregular galaxy. This is less lik...
