WebOur galaxy, the Milky Way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and about six times as much dark matter as all the stars and gas put together. And it’s all held together by gravity. Like more than two-thirds of the known galaxies, the Milky Way has a spiral shape. At the center of the spiral, a lot of …

WebOne profound result of Einstein’s theory of general relativity: gravity bends the path of light, much as it affects the path of massive objects. Very massive astronomical bodies, such as galaxies and galaxy clusters, can magnify the light from more distant objects, letting astronomers observe objects that would ordinarily be too far to see.
