Is there light in outer space?

Answer 1

Day and night are caused by the rotation of the Earth: when you're on the side away from the Sun, that's night; when you're on the same side as the Sun, that's day.

If you are in space but orbiting the Earth, depending on the orbit, there will probably be times when the Earth blocks the Sun for you and times when it does not. You could call those "day" and "night" if you wanted to, but orbital speed is quite a bit more than rotational speed until you get quite high, so your "days" and "nights" will be very short.

If you're out in space on another planet, then you've got day and night again, though to avoid confusion the term "sol" is used rather than "day". A Martian sol is about 40 minutes longer than an Earth 24-hour day.

Finally, if you're just out in space with nothing big around to put a shadow between you and the nearest light source, there's no day or night.

Answer 2

Outer space itself is a vacuum and has no atmosphere to scatter light, so it is mostly dark. However, there is light from stars, galaxies, and other celestial bodies that can be seen in space. Additionally, astronauts can see light from the Sun and reflections off of Earth and other objects.

Answer 3

Yes!!! They are named 'Eclipses'.

This is when the shadow of one astronomic body falls on another astronomic body.

e.g. Solar Eclipse. We see the Sun being 'blotted out' by the Moon. However, observed from space, we see the Moon's shadow moving across the Earth.

Similarly ,a Lunar Eclipse. From Earth we can see the Earth's shadow across the Moon.

Answer 4

As Earth rotates, different parts of it will face the sun (day); the rest will be dark (night). The tilt of Earth's axis is why there are different amounts of light and darkness during the different times of year.

Answer 5

Yes. If you stay at one spot on the moon and don't move, you see the sun rise,

take about two earth-weeks to slowly cross the sky, then set on the other side,

and stay down for the next two earth-weeks.

Whether the sun is up or down, the sky is always full of stars.

If you're sitting anywhere on 50% if the moon's surface, then the Earth is always

in your sky (and in pretty much the same position all the time), going through a

complete cycle of phases every 29.53 earth-days. If you're anywhere on the other

50% of the moon, then the Earth is never in your sky.

Answer 6

For an observer on the Moon, it would take 29 1/2 Earth days from one sunrise to the next. Also, there are extreme temperatures on the Moon, between day and night; this is mainly due to the lack of any significant atmosphere.

Answer 7

There are shadows in space... There are shadows in space because when an object block another object from the light of stars near the object and the shadow hit the object behind it then a shadow is made!!

Answer 8

No, the surrounding sky, around the star, would be just as bright as if you were NOT in a deep hole.

Please note that some of the brighest stars and planets (especially Venus) CAN be seen in the daytime, but that doesn't require a deep hole.

Answer 9

The reason that you cannot see stars in the daytime is because of the scattered sunlight that comes from every direction; the scattered light is so bright that the stars can't be noticed.

But in a deep well or pit, or from a sinkhole in a cave, only the light straight down gets to your eye; not the light scattered from all the other directions. If you can block out enough of the scattered light, you can see the stars.

In space, where there is no atmosphere, the stars are always visible.

Answer 10

Yes, it does. You can watch night and day unfold on the side of the moon that we can see, as you watch the monthly phases.
Yes. A full cycle takes about 29 1/2 Earth days.
