What is the coolest fact someone has to share about stars, space, etc.?

Ask your friend if he knows about "dark matter". \n\nAlmost all the astronomers and most of the physiscists believe nowadays that only 4% of the Universe is made of "normal matter", that is made of neutrons, protons, electrons, photosn, etc (all the aprticles contained in the standard model of Particle Physics). The rest of the Universe is believed to be made of something whose nature is still not known, 26% of this "something" is called dark matter, the name is because it doesn't interact via electromagnetism, therefore, it can not produce, or be affected by light of any frecuency, it is then dark in the sense that no instrument based on light can detect it. The presence of dark matter however affects massive bodies by its gravitational influence, in the last decades its existence has been inferred in objects of very large size, like galaxies and cluster of galaxies, there are many indirect observations that sustain the existence of dark matter, the most stronger is probably the observed rotation curves fo galaxies, which doesn't match the expectations if we account only the visible ("normal") matter.\n\nCandidates for being the components of dark matter are beyond the Standard Model of Particles, going for supersymmetry to more exotic stuff like branes and extra dimmensions. It is a very interesting fields and many projects are currently being carried pout to discover it directly or know more about its nature indirectly.\n\nThe remaininf 70% of the Universe is even a bigger mistery, it is called "dark energy". It differs of dark amtter because contrary to it, it doesn't produce an atraction like the gravitational force, but a repulsion in the large scale Universe, so it is not the same as dark matter, and of course, not the same as normal matter, it is something else, there are theories that try to describe it, but we are still in the beggining of discovering what it is.

Just what the he[[ does that have to do with astronomy and space?????????????

You don't need a suggestion for a topic.  All you need is the web site below.  The NASA picture archives should be more than enough inspiration.  Just look until you find something that interests you.\n\nGood Luck.

Earth Centered Universe.\nI have learned a lot by using this software.  It is a planetarium program of the stars viewed from Earth.  It is very easy to manipulate the program, changing direction and zoom, and moving forward or backward in time.  In doing so you learn why things work the way they do, and where and when objects will be in the sky.\nThe website is http://www.nova-astro.com/ \nand there is a Yahoo Group where you can talk to other users and even the maker of the program at\nhttp://groups.yahoo.com/group/ecusers/

i'd suggest star gazing.. that is absolutely CUTE!!!!

That teacher is on crack.\n\nAny way you define a star (celebrity or celestial object) the assignment is worthless.  \n\nI suggest this be the text:\n\n"I exist. I won't exist forever.  Just like the star.  I'm writing this. A star isn't."  \n\ncompare/contrast essay over.

Unfortunately we do not have any concrete evidence.  Here is a good quote by the late Carl Sagan:\n\n"There are some hundred billion (1011) galaxies, each with, on the average, a hundred billion stars. In all the galaxies, there are perhaps as many planets as stars, 1011 x 1011 = 1022, ten billion trillion. In the face of such overpowering numbers, what is the likelihood that only one ordinary star, the Sun, is accompanied by an inhabited planet? Why should we, tucked away in some forgotten corner of the Cosmos, be so fortunate? To me, it seems far more likely that the universe is \nbrimming over with life. But we humans do not yet know. We are just beginning our explorations. The only planet we are sure is inhabited is a tiny speck of rock and metal, shining feebly by reflected sunlight, and at this distance utterly lost."

What my colleagues are getting at is that stars (the most notable bodies within any galaxy) are simply extremely dense spheres of gas (usually mainly hydrogen and helium) that are so condensed by their collective gravitiy, they actually fuse together, forming heavier elements and releasing massive amounts of energy in the process.

For a more detailed discussion, try Wikipedia.  There is applicable information in both the History and Mythology sections.  Happy Star Gazing.

space is anything that is occupied by matter...\ndefined by dimensions...\nlike height, length and width...\n\nouter space...\nit is very vast..\njust imagine...\nyour country...\na part of the earth...\nwhich is a part of the solar system...\nwhich is a part of the milky way galaxy...\nand to think there are soooooooo many other galaxies....\nthat's outer space...\nan unimaginable dimension...

The science writer, Dava Sobel, has just published a nice little book that talks about all this stuff for non-science people. Check it out at the library. It's called "The Planets" and it has the latest stuff in it.
