Answer 1

Jupiter looks like a small dot. You can find a picture here:

Renny pointed out rightly that there won't be any twinkle.

Mars has only a thin atmosphere; however, it is extremely dusty and there is much light that is scattered about. The sky is thus rather bright during the daytime and stars are not visible.

During the Martian day, the sky is a yellow-brown "butterscotch" colour. Around sunset and sunrise, sky is pinkish-red in colour, but in the vicinity of the setting Sun it is blue. This is the exact opposite of the situation on Earth. At times, the sky takes on a violet colour, due to the scattering of light by very small water ice particles in clouds. Twilight lasts a long time after the Sun has set and before it rises, because of the dust high in Mars' atmosphere.

The Earth is visible from Mars as a double star; the Moon would be visible alongside it as a fainter companion. Jupiter looks a little larger.
