In this article, we'll find out how galaxies were discovered and what types exist, what they're made of, their internal structures, how they form and evolve, how they're distributed across the universe, and how active galaxies might emit so much energy. Contents What Is a Galaxy...

If a smaller galaxy and a much larger companion merge, it can spell the end of the smaller galaxy. Indeed, the European Space Agency'sGaiasurvey has discovered the bones and corpses of cannibalized galaxies littered throughout theMilky Way. One such example is known as theGaia sausage. This...
In 2017, astronomers foundtwo huge galaxies from the ancient universethat were formed in a sea of dark matter. The extraordinarily large size of the galaxies is making scientists wonder if they gradually grew bigger over time, or if some other process might have been responsible. Only a few m...
How was dark matter discovered? How do lenses refract light? How does an atom emit a photon? How is a photon emitted? Why doesn't electromagnetism affect light? How are electromagnetic waves generated? What is the origin of synchrotron radiation in radio galaxies?
For years, scientists believed that circlingthe center of galaxies, including our own Milky Waygalaxy, were not only stars, but lots of stellar blackholes(恒星黑洞). But scientists had yet to findevidence until now.In fact, a study suggests there may be more than10,000 black holes in the...
At the Mount Wilson observatory above Los Angeles, astronomer Edwin Hubble discovered galaxies aren't stuck in one place. => 在洛杉矶的威尔逊山(Mount Wilson)天文台,天文学家埃德温·哈勃(Edwin Hubble)发现,星系并没有卡在一个地方。 Not only are they moving, but they're flying away from Earth ...
“The galaxies are comparable in size to the Magellanic Clouds, dwarf satellite galaxies of theMilky Way,” Geha said. “Previously, such galaxies were thought to be too small to have such massive black holes,” she added. In the nearby Universe, astronomers have found a direct relationship ...
An amateur Italian astronomer discovered five dwarf galaxies, and they are now named after him. Amazingly, these aren’t even astronomerGiuseppe Donatiello’sfirst discoveries. He’s made 11 celestial finds in all, nine of which bear his name,according to an interview he did withSpace.com. ...
