are stars visible in outer space?

Fast exposure times means they can get good pictures of the bright Earth or lunar surface, but it also means no stars in the picture. Even in space, stars are relatively dim, and simply don't produce enough light to show up in photos set for bright sunlight.

Most stars are much like the Sun—giant balls of gas burning billions of miles away. These spherical stars pump out a steady stream of light that crosses vast stretches of space before it illuminates the night sky.

But the stars, including the Sun, travel in their own separate orbits through the Milky Way galaxy. The stars move along with fantastic speeds, but they are so far away that it takes a long time for their motion to be visible to us. You can understand this by moving your finger in front of your eyes.

Gas, dust and other bits of matter float around "emptier" areas of the universe, while more crowded regions can host planets, stars and galaxies. No one knows exactly how big space is. ... This means we can "see" into space at a distance of almost 13.7 billion light-years.

But relatively recently, scientists have discovered that a new form of diamond exists. ... It is now known that there are diamonds in outer space; some, tiny fragments not even big enough to put on a ring, but more recently, stars as big as the sun and planets as big as the Earth, comprised largely of diamond.

Unlike stars, planets don't twinkle. Stars are so distant that they appear as pinpoints of light in the night sky, even when viewed through a telescope. Because all the light is coming from a single point, its path is highly susceptible to atmospheric interference (i.e. their light is easily diffracted).

Why Do Stars Appear to Move in the Night Sky? ... These apparent star tracks are in fact not due to the stars moving, but to the rotational motion of the Earth. As the Earth rotates with an axis that is pointed in the direction of the North Star, stars appear to move from east to west in the sky.

Every star you see in the night sky is bigger and brighter than our sun. You can't see millions of stars on a dark night.

1 Answer. Stars produce electro magnetic radiation in many wave lengths. But Earth's atmosphere blocks some of them. On earth's surface we get visible light, radio waves and some infra red.

Some stars are known to have planets orbiting around them (our sun is one example!), but not all stars have planets. A solar system is a star with its planets. Our solar system consists of the sun, the Earth and eight other planets.

The sky is always the same and the stars are always there even if you cannot see them because daylight outshines them or the Earth blocks your view of them. Stars don't appear in the same constellations, they remain there. They do move, though. It just that they are so far away that you can't detect their motion.

Why do stars only come out at night? The stars are in the sky both day and night. During the day our star, the Sun, makes our sky so bright that we cannot see the much dimmer stars. At night, when the sky is dark, the light of the stars can be seen.

No. Pulsars themselves are really tiny, and in addition they radiate mainly radio and x-rays, not visible to our eyes. ... What you may see with a small telescope are supernova remnants harbouring pulsars - like the Crab nebula.

Stars make their own light, just like our sun (the sun is a star — the closest star to Earth). But the stars are very, very far away from our solar system so they appear to be very tiny to us, even though up close they are large. The planets are much closer, inside our solar system.

Originally Answered: Are the stars visible at 7pm still visible at 11pm in their original position? No. Because as the Earth rotates on its axis once a day, your point of view rotates with it. In the northern hemisphere, the stars appear to rotate around a point near the North Star (Polaris) once every 24 hours.

Stars are so far away they are point sources, and twinkle a lot. The visible planets will twinkle much less, since they are not point sources. ... Satellites are not point sources, and will twinkle much less than stars. Most satellites have a high velocity across the sky.

To date, scientists have explored about 4 percent of the visible universe. That's made up of planets, stars and galaxies that astronomers can see.
