Isn’t it surprising that scientists have a better understanding of how many stars there are in the galaxy (银河系) than how many species there are on Earth Their estimates of global species diversity vary from 2 to 100 million species. Most people agree on an estimate of somewhere near l...
Although there are only six known pairs of neutron stars on a path for collision, scientists believe there are many more out in space and that these types of mergers could happen as frequently as once or twice a year. What about space collisions on a much smaller scale, such as one betwe...
100 billion stars in our galaxy the Milky Way. But the Milky Way is just one of billions of galaxies that we know about! Some other scientists say there are 2 000 000 000 000 000 000 stars! The largest star that we know about is called the Pistol Star (手枪星). The PistolStar ...
There are about 100,000,000,000 stars in the Milky Way Galaxy.Some of these stars are much larger than the Sun and others are much smaller. There are trillions of galaxies in the universe. Dwarf galaxies (系) may have as few as ten million stars, and giant galaxies (巨星系) may...
aQuicktimeVR also includes Object Movies. In opposite to panoramas, which are an environment viewed from a centered single point of view, quicktimeVR objects are a set of photos of an object captured from around a circle pointing to the object. It is QuicktimeVR也包括对象电影。 在相对于全景...
Centauri (半人马比邻座星) isthe closest star at 4.2 light years away: Some of the brightest stars are more distant Rigel (参宿七), in the constellation Orion (猎户星座), is the seventh brightest star inthe sky but is 900 light years away. To see the faraway stars, scientists use the Hu...
An of research done by Chiara Feruglio with the National Centre for Scientific Research and colleagues, which found that the flow rate of gas from a distant galactic centre was large enough to cause star formation to stop, is presented.

Earth resides. Part of it is visible on a clear night (from sufficiently dark locations) as a thick opaque band of stars and dust stretching across the sky. We can see thousands of these stars with the naked eye, and many more with a telescope. But how many stars are in the Milky ...
The sun is just one of about 200 billion stars in the Milky Way, our home galaxy, which is just one galaxy in the universe. 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,...
