In fact, that will be the fate of our own sun in roughly 5 billion years. But how quickly does the night sky change, and in our galaxy, the Milky Way, how many stars die each year? According to James De Buizer, a research scientist at the Search for Extraterrestrial Intelligence (...

阅读理解。 Do you know how many stars there are in the universe? The answer is WANY! 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...

The difference is distance: The other stars we see are light-years away, while our sun lies only about eight light minutes away — many thousands of times closer. Officially, the sun is classified as a G2 type star, based on its temperature and the wavelengths or spectrum of light ...

anywhere from a few light-years to a few billion light-years away. And everything astronomers "see" in the distant universe is literally history. When astronomers study objects that are far away, they are seeing light that shows the objects as they existed at the time that light left them...
To best capture the Milky Way, you need to findthe dates of ideal visibility and pick a night when the sky will be clearand free of light pollution and moonlight. There are many tools and apps that will help you find the best dates to photograph the Milky Way, including its position ...
If you could travel at light speed. Which, unless you’re aphoton(a particle of light), you can’t, and, by current physics, might never be possible. But I digress. Can we get back to those…X-planets? Exoplanets. Let’s toss around some more big numbers. First, how many are the...
