The Milky Way is Earth’s home galaxy, the stellar town in which we reside. It’s significant, that contains a couple hundred billion stars. And it is so roomy that, even traveling at the pace of light-weight, it would get far more than one hundred,000 many years to get from a single facet to the other. (It’s Frisbee shaped, while so, from major to base, you could travel as a result of on a shorter, thousand-light-weight-yr jaunt.)
Current study has doubled the Milky Way’s span to potentially two hundred,000 light-weight-many years, exhibiting that when the population of stars grows less dense in our galaxy’s outer rim, a gauzy scattering stretches perfectly previous what experts experienced earlier noticed.
Between the stars are big pillars of gasoline and dust, and at the middle of it all lurks a black hole weighing 4 million times the mass of our sun.

The Milky Way also consists of far more mysterious stuff. Much like the rest of the universe, some thing like 95 p.c of the Milky Way’s mass is taken up by invisible dark make a difference, detectable only by its gravitational sway. Insert it all collectively, and the Milky Way — with its couple billion stars — ends up clocking in at around 1.five trillion times the mass of our sun.
Yet from a different, far more cosmic perspective, you could argue that the Milky Way is reasonably unimpressive. Our nearest full-sized galactic neighbor, Andromeda, is twice as huge (while the two galaxies have about the identical mass). And the universe consists of galactic leviathans like IC 1101, which consists of some one hundred trillion stars and stretches 4 million light-weight-many years throughout.
