What causes stars to be visible?

Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.

How does a star look like from Earth?

Viewing the stars from Earth is a bit like looking at them through a a water filter because, compared to the emptiness of space, the atmosphere is dense. Moreover, air is always moving, so starlight appears to be shifting and shimmering.

What’s the best way to see stars in space?

Why can you not see stars from space?

Actually you can see millions of stars from space with your naked eye, but when you take photographs in space and have something bright in the frame like a spacecraft, spacesuit, or lunar soil, you have to stop the exposure way down to prevent overexposure. And that is why you might have not been able to see the stars in the pics taken from space.

Can you see the Milky Way from Earth?

For example, if you are outside (on Earth) on a dark night and can see thousands of stars, if you just take your camera or phone camera and snap a quick picture, you’ll just get a darkness. Earth-bound astrophotographers need long-exposure shots to capture the Milky Way.

It contains hundreds of billions of stars, star clusters, and clouds of gas and dust (called nebulae) where stars are born. Here are the ten brightest stars in Earth’s night sky.
