To get a direct image of a planet, we need to gather the light it is reflecting. Planets in our own solar system are much closer and thus, they appear bigger - and they can often be found far enough away from where the Sun appears to be, so that the Sun's light doesn't affect the imaging effort.
However, when a star is many light years away, and a planet is around it, it will appear very, very close to its parent star - which is essentially blinding it out.
Imaging trying to gather the light reflected off a grain of sand which is sitting next to a large flashlight shining in your face.
Because of their distance from us. The light emitted by such planets is very faint, compared to their host stars, the planets are very, very close to their host stars (as seen by us), and the star outshines them (i.e., an object of the same brightness would be easier to observe without the presence of another, much brighter, object nearby).
For the most part, planets are invisible to us. Stars make their own brilliant light: we can see some of them, but planets do not. We know about most extrasolar planets by observing how they make their star wobble ever so slightly from the force of gravity.
Dark planet. Bright star. The planet being further from the star can make it more difficult as well. So distance and the contrast of light and no light.
It is likely that stars are way brighter, and that planets are much dark, epsecially if the planet is far away from its orbiting star.
Because of the way the planets are changing phases
Their light is overwhelmed by the light of their star.
a satellite
It takes pictures of nebulae, stars, planets galaxies, supernova remnant and more.
Plants take in carbon dioxide and give off oxygen. I think the question is about planets. Planets take in energy from the Sun (mainly in the visible part of the spectrum). Planets then give off infra red radiation.
Generally I'd say Jupiter, but Uranus and Venus also have the same gaseous stripes as Jupiter. Take a look at some satellite pictures of the planets and decide for yourself
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
its called a satellite, a large object floats in space above earth to take pictures of stars and planets

Mostly to study other planets and to find out about our solar system. They are used to take pictures of planets as well.
To see planets, stars, comets and to take pictures.
To take pictures of space objects and observe planets and their movement.
Because nobody is there to take it... plus, we want a more detailed image of it. Also, fpr gas giants, it would be very difficult to capture
well it really didnt discover anything it was sent into space to take pictures of planets
artificial satellites are used for scientists to study planets and take pictures and learn about space. natural satellites are just pretty much there, they rotate the planets just like our planets rotate the sun. the moon is one of earth's natural satellites.
Things that the Voyagers both did was take pictures of gas planets and record sounds from them planets as they orbited them. Now the Voyager 1 heads to the interstellar space while the voyager 2 does work on the outer solar system.
No you can take pictures
