Do you know how many stars there are in the universe? The answer is MANY! Our sun is one of about 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...
How many stars are in the Andromeda Galaxy? What is the magnification of the Hubble Telescope? What has the Hubble Telescope discovered about the universe? How many miles of wire are in the Hubble Telescope? What can the Hubble Telescope see?

the next star over. A little more than four light-years away, or 24 trillion miles as the crow flies. If an airline offered a flight there by jet, it would take 5 million years. Not much is known about this world; its close orbit and the periodic flaring of its star lower its chan...
How did they form so early in the universe? 这是一个有趣的谜团 This is an interesting mystery. 类星体是我们能看到的最远的天体 We see quasars about as far as we can see. 这意味着这些天体存在于最早的星系中 That means these objects existed in the very earliest galaxy. 这意味着有一百万...

What you’re seeing is a portion of the Milky Way, our home galaxy, which measures 100,000 light-years in diameter. (A light-year is the distance light travels in one year — almost 6 trillion miles, or 9.5 trillion kilometers.) Its core hosts a supermassive black hole — a giant gr...
A light year is the distance light can travel in one year, or about 6 trillion miles. So the baby planet may seem far, but compared with many other distant stars and galaxies in our universe, it’s actually relatively close. Our galaxy, the Milky Way, is 100,000 light years wide. ...
