So, how many galaxies are in the universe? 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...
How many galaxies can you name? Researchers have identified two ancient star groups that appear to be among the Milky Way Galaxy’s earliest parts. The groups are named after the Hindu gods Shakti and Shiva. They were discovered using observations from the European Space Agency’s Gaia space ...
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?
All galaxies on average are moving away from us, and, stranger still, those that were twice as far away were moving twice as fast. => 所有的星系平均正在离我们而去,而陌生人呢,那些距离两倍远的地方的移动速度却快了一倍。 And those that were three times as far away were moving three times ...
Only a few months after that discovery, astronomers also found a group of galaxies that were orbiting in sync with each other in a pattern that may be explained by dark matter. But in 2018, a group of researchers challenged the dark matter theory when they discovered that a galaxy called ...

For researchers like Bullock, whose career and everything he has discovered depends on dark matter being the thing that causes galaxies to behave the way they do, the confirmation that galaxies lacking dark matter can be explained in a universe where there is plenty of dark matter is a si...
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...
