How does gas cycle through galaxies
WebSep 15, 2016 · The reason galaxies die, according to new research, lies with the supermassive black holes that lurk at the centers of dead galaxies. In a recent paper, scientists revealed these black holes are spewing out energy that heats up gas in lifeless galaxies—gas that otherwise would cool and condense into new generations of stars. WebJan 4, 2024 · The dust and gas in spiral galaxies are consistently fueling the formation of new stars. Elliptical galaxies lack the spiral arms of their more flamboyant cousins. Their appearance ranges...

WebAs the cloud collapses, a dense, hot core forms and begins gathering dust and gas. Not all of this material ends up as part of a star — the remaining dust can become planets, asteroids, or comets or may remain as dust. In some cases, the cloud may not collapse at … WebSome spiral galaxies may have formed in relatively isolated regions from a single cloud of gas that collapsed to make a flattened disk, but others acquired additional stars, gas, and …

WebAfterward the galaxies changed only slowly as the stars evolved. This is what astronomers call a “top-down” scenario. The second model suggests that today’s giant ellipticals were formed mostly through mergers of smaller galaxies that had already converted at least some of their gas into stars—a “bottom-up” scenario. WebGalaxies Our galaxy, the Milky Way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and at least ten times as much dark matter as all the stars and gas put together. And it’s …
