I'd like to buy a telescope and be able to search the night time sky in summer. But the specs for telescopes confuse me. It will be my first purchase, yet I'd like to buy a good telescope for around 300-400 dollars. Thanks for your help.

From the Earth's standpoint the comet is either behind (evening) or ahead (morning) of the sun. Is this a weird positional geometry peculiar to this particular object?

I would. I would love to see Earth just sitting there all lonely. To travel the universe. See things no one else has seen. Go places no one else has been.

It is impossible for moon to rotate around it's own axis but still hide it's one face from us always. If we can see only one face always, then automatically it implies Moon doesn't rotate around it's vertical axis. It may rotate around it's horizontal axis and still show only one face but not around vertical axis.

Irrespective of how fast it rotates, irrespective of how much time it takes if it is truly rotating around it's vertical axis then it has to has to has to show it's other face.

i agree the same area of earth may always see the same face of earth but we are talking of whole earth; if whole earth cannot see other face of moon then it is not rotating around it's vertical axis.

Now think of 2 people standing in front of each other face to face. Let us assume both rotate around their vertical axis. Let us also assume person B rotates around person A. If person B really rotates around his own axis now tell me how is it possible that A never sees the back of B??? irrespective of the speed with which B rotates, irrespective of the time he takes to finish 1 rotation around A at some point the has to show his back to A.

it is impossible for moon to rotate around it's own vertical axis and still hide it's other face from earth irrespective of how it rotates as long as it is around it’s vertical axis.

it is impossible. I know people will come out with some explanations like ' moon's rotation is locked with …etc etc ' ‘ it takes same time for rotating around it's own axis as well as 1 rotation around earth bla bla’ but in my opinion;

In my opinion moon actually doesn’t rotate around it’s own vertical axis ( also around any axis ); perhaps the gravity of Earth has completely prevented Moon from ever rotating around it’s axis.

It also raises the interest possibility that not all planets or moons or celestial bodies in the universe do have to rotate around their own axis. If there are 2 movements; 1) moving around another celestial body 2) moving around it’s own axis; I feel the first type of movement is mandatory ( moving around another, mostly bigger celestial body like earth moving around Sun, moon moving around Earth etc ) and the second type movement ( moving around it’s own axis ) is not mandatory. Obviously I don’t think there could be an object in the universe which could just float in the sky possibly moving around it’s own axis but without moving around something else.

This is my opinion, I appreciate a feedback in this regard. In other words the above discussion is actually a question although it looks like a reply or response.

Thanks.

Some years ago I remember N.A.S.A was trying to develop or developing a mirror in space that would light up an area an extra 12 hours a day by reflecting the sunlight to an area that needed this (earthquake regions etc)
Do I remember right?
And if so then can you point me in the right direction on the net for info pls?

All the footage I have ever seen of astronauts working on sattelites, space stations, or space shuttles, has never shown a single star in the sky. Is this a cause of the sun blinding them out?

Doesn't the moon also rotate on its own axis like Earth does? If that's the case, surely we can see all the "sides" of the moon at one time or another.

If they are separated by 3 hours (time zones), why couldn't I get in a plane that flies straight up, wait for 3 hours, and then land as the West coast approaches below me?

I know that a rocket has to achieve about 27,000mph to ecape into orbit. But would not it be possible to go slowly vertically into orbit by just over coming gravity. Gravity reduces as you get higher.

If and when we need to escape our solar system how could we create a portable SUN solution to take with us and how would this effect the gravitional requirements of the propulsion systems in place to propel us and break away from our current orbit around our SUN?

I saw a documentary a few years back that mentioned a plan for an array of orbital radio telescopes that would function in unison; and kept in sync with lasers. I think it said it was supposed to be implemented around 2014. Does anyone have any info on this?

If one day we did find a planet with other intellegent life and landed on that planet. How would we communicate? We would have different language. A simple hand wave by us might mean something bad to them.How would we communicate?
