What is the different between space and astronomy?

space is a thing, astronomy is the study of it.

The sky begins where atmosphere touches anything on the earth's surface.  The sky ends and space begins when you reach the height above the earth's surface where there is no atmosphere, only empty space.

Everything about space is interesting. It is all a mystery and so much is yet to be discovered. I used to love to study the planets when I was in school. I love to watch the stars and wonder what is up there and what it is really like to be billions and billions of miles away from the earth

Our eyes perceive energy in the visible light range that is either emitted from a source, or reflected off an object.  In space, the light sources are stars, like our Sun.  Objects like planets and comets and asteroids and dust, reflect the light emitted by the stars.  Since space is a vacuum, there isn't anything to reflect the light, therefore it is black.

Galaxies are clusters of stars and its planetary systems found in groups across the universe. List of Galaxies can be found in link below. \n\nThey are really far... measured in light years and the distance is increasing as per our expanding universe.

sky is just a small portion of the universe.\nit cud have a pillar if one cud go to the ends of the universe.. but even the most elaborate and sensitive radio telescopes cant reach all that is up there.. \n\nthere are more stars and galaxies un-named...... and counting....\n\nil let u know once i found out what makes the sky stands up there... with or without pillars. \n\nafter a million light years.....P

it depends on your place in space. are you in a straight line with a planet and sun,  then there is night and vice versa

Space doesn't exist. There are things IN space. Matter makes up the stars and planets and gasses and eveything you see. Everything you DON'T see, I.E. the large black void, is nothing. There is no matter or antimatter or anything there. It's just....emtpy. Therefore, it doesn't exist. Only the things in it exist.

Space exploration is the physical exploration of outer space by both manned and unmanned spacecraft. The development of large liquid-fueled rocket engines during the early 20th century allowed space exploration to become a practical possibility; it is distinct from the earth-based observation of outer space, known as astronomy, which has occurred for millennia.\n\nSpace exploration is more of an investment into the future as it provides the foundation of our knowledge, technology, resources, and inspiration. It seeks answers to the fundamental questions about our experience, responds to recent discoveries and puts in place revolutionary technologies and capabilities to inspire the world and the next generation. For example everyday things such as aluminum foil, saran wrap, LED, soles of your running shoes, your quartz watch, glasses with scratch resistant lenses and doppler radar - many common things you use today come from the space program or related to it. Weather patterns, genetics, food production, power recycling, habitat efficiency - it's all applicable to making life on Earth better and more sustainable. From orbit, with new sensors and other devices, we have learned more about our planet than people did in the previous century. El-Nino crap, fish migrations, plankton blooms, oil spills can be tracked, tropical storms and hurricanes, tracking tsunamis, etc, etc, etc. \n\nWithout human participation where is the adventure, the history, the determination as a species. How many early sailors died on this planet’s oceans for thousands of years and even today. It is the price we pay when we venture into the elements be they earth borne or space, albeit all the lives that are loss have a special place in our hearts. Without the exploration of space we cannot evolve as a whole on the rate we are now.\n\nOf course, once you throw politics into the mix as given in today's space exploration environment, the spectacular and publicly quantifiable begin to matter more than the mundane but scientifically useful. As far as going back to the moon and Mars, I'm pro-exploration, but for its own sake rather than for political gain.\n\nWhile the money spent on space exploration results in new innovations that go on to make more money, I do believe that a portion of that money should be utilized towards solving issues at home first (poverty, famine, pestilence, war - The Four Horsemen of Life!). We need to solve our problems at home before we take them somewhere else. There's no need for people to starve; there's no need for war... Yet we still do. Why not spend a few millions into researching our selfish nature? Find out why we are so self-centered, and then use the massive propaganda machine that we have constructed to do battle with it.\n\nThe two aspects (space exploration and solving issues at home) are not mutually exclusive. But we must remember that our perspectives will always outreach our means. This is the sad truth.\n\nPls. also have a look at the following Yahoo answers link for other views on this subject:

Even the difference between space where the space station is thicker than space between the Moon and Earth which is thicker than the space between Earth and Mars which is thicker than the space between stars in the milky way which is thicker than the space between Galaxies!!!!\n\nMostly the (very small amount ~10^(-18) ATM) gas is hydrogen

Astronomy:The life of Stars. You can get some awesome pictures for that and there is plenty to write about, like (i am not completely sure about this number)did u know that light takes almost 250,000 years to travel from the center of our sun to the surface.\n\nhttp://en.wikipedia.org/wiki/Star

A star is any massive gaseous body in outer space, just like the Sun. Unlike a planet, a star generates energy through nuclear fusion and therefore emits light. All stars except the Sun appear as shining points in the nighttime sky that twinkle because of the effect of the Earth's atmosphere and their distance from us. The Sun is also a star, but it is close enough to Earth to appear as a disk instead, and to provide daylight.

There are many differences.\n\nBy the wording of your question, it sounds like you are speaking about the movement of celestial bodies.\n\nMost stars (except the sun, seem to stay in the same position in relation to one another.  The sun, moon and   the planets, change their position against the background of the "fixed" stars.  \n\nThis is because the objects in our solar system are close to us, so their change in position is much easier to see.  The fixed stars are so much further away, that their motion is harder to detect.\n\nThis is similar to the experience of riding in a car.  If you look at a distant mountain,  the appearance of it doesn't change very quickly.  But as you come close to a street or a building, the appearance changes dramatically. \n\nThe reason is that if you measure apparent motion by an angle,  an object twice as far from you must move twice the distance across your Field of vision to have the same apparent motion.

Time refers only here on Earth. Where there is 24 hours in a day. In space, time does not exist. If you travel millions of light years away and then come back, you'll find out that people you know are way older than the last time you saw them.

Star's are for the most part the same as our star/sun. The difference being we named our star The Sun.

what is this?  this is not a question about astronomy.\n\nhttp://en.wikipedia.org/wiki/Astronomy
