I've always had an interest in astronomy but never really had time until now to start taking a more active interest. What sparked my interest is that I've noticed a bright object in the east in the early evening but I have no idea whether it's a star or a planet. Can anyone help? Also what software would you recommend for a Mac user. I used to have Red Shift many years ago but not sure if that's available for the Mac.

That's the planet Jupiter. Should be visible in evenings right through
until Spring 2012.

A clue to differentiating a star from a planet with the unaided eye is to note whether or not the object twinkles.
If it twinkles, the odds are that it's a star rather than a planet. The planets tend to give off a steady light, although they can scintillate when low down in the atmosphere, due to air turbulence.

Hello and welcome.

You could download Stellarium (http://www.stellarium.org), free planetarium software which will help you find your way around. It shows the night sky in real time and is available for Mac.

And don't mistake it for a flare!
