don't you need space telescopes to pick up the most distant non-pulsar objects?
no. you need a big collecting mirror/dish, which are always going to be ~10 times bigger (and therefore 100 times more efficient) on the ground than in space (even as space telescopes get bigger)
(i think you're confused about what pulsars are btw. they are not particularly bright. you can't really see them outside of our galaxy, either from space or the ground. when you can see them, you detect them in radio, which you can do much more easily from the ground (a radio telescope has be be hundreds of meters big these days, and does not look like a "telescope").)
you get x-rays from very very large structures (e.g. clusters of galaxies). it comes from the gas that surrounds them, which is very hot. x-ray observations are a good way to probe the large scale structure of the universe and figure out how wrong your sums are.
http://www.jwst.nasa.gov/ is going up in a few years. that's a 6m mirror. going to be a pretty big deal iirc.

cool :) so space telescopes are for the two extremes: really pretty pictures and really uncharismatic but vital details about the mass of extremely distant objects
yeah i knew pulsars were only found by radio telescopes, and only then when they happened to be beaming in the correct orientation - i had been asking earlier whether these new telescopes were radio telescopes but it appears they are conventional, just enormous
also nice links guys, will peruse

I don't understand gravity. if I spin a ball, objects resting on its surface fly off of it. how do we stick to the earth?

iirc centripetal force keeps us in a sort of fixed harmonious orbit around the earth's centre, as for gravity, well, help us caek
― with 4 magical horns & 3 figures to impale! (acoleuthic), Wednesday, 3 March 2010 16:43 (fourteen years ago) link
no one understand's gravity. it just is. things with mass are attracted to each other. that is the way of things. people are working on understanding it, but given it's the most familiar force on the day-to-day, it's odd that it's by far the most poorly understood.
lj's centripetal force comment is not even wrong.

i am getting better at science iirc - either that or i am now making sure i only say the stuff i know to be truthful
gravity is caused by god fyi

yeah I get centripetal force conceptually but gravity seems like mysterious magic and I was hoping someone had figured it out since the last time I took a science class
