When we talk about the enormity of the cosmos, it’s easy to toss out big numbers – but far more difficult to wrap our minds around just how large, how far, and how numerous celestial bodies really are. As with many things that talk about items on an astronomical scale, this requires a little bit of information to accurately process. Short answer : The Milky Way is larger than your average galaxy, but it is not nearly as large as the largest gala Due to relativity, the speed of the Milky Way varies when compared with different objects in space. For example, I have learned from my research that the Milky Way and Andromeda galaxy are approaching each other with a speed of about 130 km/s, however the collision of these two galaxies will not occur for about 5 billion years ( AstroFile ).

“For some context, the lowest mass galaxies are around a The Milky Way is 2.5 times more massive than M32 was when it tangled with Andromeda and it's expected to make new stars over time, getting even larger. The rotation and trajectory of our galaxy will ultimately determine whether Andromeda and the Milky Way collide head-on or if our galaxy is slowly unwound. We have time to make these predictions. “There are other galaxies, typically more spherical galaxies, that have a very pronounced shell structure, so you know that these things happen, but we’ve looked in the Milky Way and hadn’t seen really obvious, gigantic shells,” says Thomas Donlon II, a Rensselaer graduate student and first author of the paper. The Milky Way galaxy compares fairly averagely- it's a spiral galaxy of the larger sort, revolving slowly and is relatively at a medium age as far as galaxies go.
also interact within galaxies. Even the Milky Way galaxy as stated by the Hubble Expansion of the Universe the universe is expanding at a steady rate, but as the universe expands it is not simply moving apart; many galaxies are, in fact, interacting with one another in a sort of cosmic pinball. Possibly the Milky Way is one of the very few local galaxies that could be a direct descendant of very distant, z=2-3 galaxies, thanks to its quiescent history since thick disk formation.

The diameter of the disk is about 100,000 The Milky Way is our home galaxy. The Milky Way is spirally shaped having length of about 1,00,000 light-years, and width of 10,000 light-years. It contains billions of stars which include our sun. You can get a glimpse of the band of stars in the Milky Way from a dark place at night. Finally, I show that as far as structural parameters are concerned, NGC 891, 5033 and 5375 closely resemble the Milky Way Galaxy.

The outer planets follow in the same direction with for instance Neptune in It is different from many other similar bodies in that it rotates very fast, one turm in 4 On its journey through the Milky Way it happened to cross our solar system. We also study other stars than the Sun, and for some of them we can even detect more about our galaxy – the Milky Way – and about all the other galaxies,

English: M33, the Triangulum Galaxy, is a perennial favorite of amateur and These observations of M33 allow astronomers to compare the population of young, massive stars with other components of the galaxy, such as interstellar dust and
