The Milky Way is Earth’s residence galaxy, the stellar city in which we reside. It’s hefty, made up of a couple hundred billion stars. And it is so spacious that, even traveling at the velocity of light, it would acquire extra than 100,000 a long time to get from just one aspect to the other. (It’s Frisbee shaped, however so, from prime to bottom, you could push as a result of on a shorter, thousand-light-year jaunt.)
Current research has doubled the Milky Way’s span to probably 200,000 light-a long time, displaying that whilst the population of stars grows less dense in our galaxy’s outer rim, a gauzy scattering stretches well past what researchers experienced beforehand observed.
Amongst the stars are huge pillars of gas and dust, and at the centre of it all lurks a black hole weighing four million occasions the mass of our solar.

The Milky Way also contains extra mysterious stuff. Substantially like the rest of the universe, something like 95 percent of the Milky Way’s mass is taken up by invisible dark make any difference, detectable only by its gravitational sway. Insert it all with each other, and the Milky Way — with its couple billion stars — ends up clocking in at approximately one.5 trillion occasions the mass of our solar.
Still from another, extra cosmic perspective, you could argue that the Milky Way is quite unimpressive. Our closest comprehensive-sized galactic neighbor, Andromeda, is 2 times as large (however the two galaxies have about the same mass). And the universe contains galactic leviathans like IC 1101, which contains some 100 trillion stars and stretches four million light-a long time throughout.
