is it in the shade in outer space?

because of the temperature dif-
ferences between the sunny and
shady sides?

Keep in mind, an object in orbit doesn't just have to deal with the thermal differences involved in going from the Sunward side of a body to its dark side; the object also has its own shade. The Shuttle and stations have "circulatory systems" to help cope. Thay continually circulate fluid around just under the skin, taking heat from one side to the other, while the craft is exposed to sunlight.

And did that actually turn out to
be a problem? Given what marcus
brought up about the slow rate
of radiation it doesn't seem
unlikely.

Do you have any idea what fluid
they circulate, Lurch? What
earthly anti-freeze could with-
stand 3 Kelvin?

Zooby indeed because of the slow rate of radiating heat
it is hard and even costly to dump waste heat
I have been thinking about this a little and nothing obvious strikesOriginally posted by marcus ...it follows an amazing fourth-power law discovered by two Viennese gentlemen of the Victorian era and half raised to the fourth is a sixteenth

me about Vienna during the reign
of Victoria that would induce two
gentlmen to start wondering about
radiation in the cold vacuum of
space. What is their story?
You have to remember that since there is no air in space heat can only be carried away by radiation. So its not like the skin temperature of the shuttle is 3K.Originally posted by zoobyshoe

New McDonald's technology allows NASA engineers to "keep hot side hot; cool side cool"!

Yes, in spite of frigid phenomena due to Earth's tilt guaranteeing that its subpolar regions are shaded for months at a time, the Earth is sensitive to waste heat radiation. Futurists predict that if all the third world were brought up to US standrds of energy usage the resulting waste heat would warm the Earth by several degrees. This is in addition to the usual greenhouse sources of global warming.

I find this disturbing because it
amounts to a disincentive to help
third world countries better their
standards of living. Would a way
around this be to foster the use
of solar power, which is already
being delivered there anyway dir-
ectly as heat?
What, exactly, is a futurist? Are
there people employed to calculate
things like this about the future?

Which makes perfect sense but,Originally posted by selfAdjoint
The moral usually drawn is not that third world countries should stay as low in energy use, but that first world countries (and especially the biggest user of all, the US) should reduce theirs!
No, it is not always dark in outer space. While the majority of space appears dark due to the lack of sunlight, there are still objects that emit light such as stars, planets, and galaxies. Additionally, astronauts have reported seeing bright flashes of light caused by cosmic rays and other high-energy particles.
Outer space appears dark because of the lack of atmosphere and objects that can reflect or scatter light. On Earth, the atmosphere scatters sunlight, creating a blue sky during the day. In space, with no atmosphere to scatter light, the sky appears black.
Yes, there is light in outer space. As mentioned before, there are objects that emit light such as stars and galaxies. There is also light from other sources such as cosmic background radiation and light from nearby planets and stars.
Yes, it is possible for there to be areas of light in outer space. For example, nebulae are areas of space where gas and dust reflect and emit light, creating stunning and colorful images. There are also areas of space where stars are clustered closely together, creating a brighter region.
Yes, humans can see stars in outer space. In fact, astronauts on the International Space Station have reported seeing thousands of stars in the dark sky. However, due to the brightness of the sun, it can be difficult to see stars during the day. Astronauts must wait until the sun sets or their spacecraft orbits to the other side of the Earth to see the stars clearly.
