At our current technological level, if humanity pulled its economic resources together to fund such a project, which would be the most feasible planet in our solar system to terraform (as in, would it be easier to warm up mars or cool down venus)?

Why 'on earth' do we see only one side of the moon ?

If we are hit by a CME what may happen? Also, can we predict them and how? What can we do to protect ourselves?

Consider a tiny cell. And in this cell there are millions of atoms(or more). Now consider a galaxy where it too, includes millions of solar systems(which looks like atoms).

So the question is, does anybody else think that our solar system is nothing more than a tiny atom inside a cell(known as the Milky Way) of something very, very huge?

I know the earth's orbit around the sun is in the shape of an ellipse.

The sun is one focal point, but what is the other.

Baffled ! :)

I was profoundly struck by some images of Saturn that Sir Patrick Moore was presenting on TV and I had a revelation..The Rings of Saturn have fascinated me from Cradle to Dole Queue and on studying them tonight, strike me as a valid and viable form of data-stream, akin in many respects to the grooves on a vinyl LP or the digital binary spiral track of a DVD or CD.THIS IS WHERE YOU CAN HELP.! I would love to hear any thoughts on the possibility of setting about attempting to create a musical analogue, accurately interpreted from Hi res images taken of Saturn’s rings; We have all at one time or another had scratched or messed up Vinyl discs or cds.. etc. Right.? And we all know it still always at the very least sounds like SOMETHING, no matter how distorted or random the damage or distortion.My bet is:- That if someone is prepared to stamp a scaled down image of Saturn’s rings and join each rotation to it’s sub neighbour on a piece of black vinyl and I pop it into my Granddad’s gramophone we are going to hear either the secret of the genesis of life in our universe or The Colonel’s secret recipe - in Saturn-Ian. Or, at the very worse something better than, anything from the pop 90s Charts.I know this sounds a little ‘April fool!’, buts that’s just how I roll.Who’s with me?

PS. it doesn’t need to be the vinyl idea it will in all probability have to be digital..Sincere Musical and Scientific Hugs Big G.

My limited understanding of science tells me that

a year is the period taken for the earth to orbit the sun, but

seasons are dictated by the tilt of the earth.

Why should there be a link between these?

I've just been looking at some of the pictures voyager took of Uranus and Neptune. If I'd gone along for the ride would I have been able to enjoy the view with my unaided eyes, or is it quite gloomy so far from the sun? Could I read my newspaper on Pluto?

i understand that there are 2 main ways to observe and determine properties of exoplanets but my question relates to the method which involves measuring the "wobble" caused by the gravitational influence of a planet on it's parent star. is the measurement always based on the assumption that only one planet is present in the solar system in question and would the presence of other, as yet unobserved planets affect conclusions drawn about the mass and orbital distance of the planet. would the presence of other orbiting planets cancel out the "wobble" or accentuate it?
