Can you see the surface of a star from using the telescope u buy from the shop?

If by surface you mean disk, then no, you can't.

Stars (except for the sun of course) are so far away, that no matter how much magnification you have, all you'll see for the stars will be points of light. But the thing is you'll be able to see fainter stars, so even if you'll see them as dots, there's gonna be more of them!

The detail you get from a telescope comes from its aperture (how wide it is, its mirror or its lenses). Don't buy telescopes that advertise 600x magification or the like, that is not possible with supermarket scopes.

Through a good commercial telescope you'll be able to see details on the planets of our solar system (Mars, Jupiter, Saturn), nebulae (like the Orion Nebula), craters on the Moon, Sunspots on the sun and more. You notice that the telescope will help you see FAINTER objects better, it doesn't mean anything to ask HOW FAR.

Try to buy a telescope from a specialized store, like Celestron, Meade etc. Stuff you can buy from the supermarket is usually substandard cheap crap.

Oh yeah: NEVER LOOK AT THE SUN WITHOUT PROPER FILTERS. YOU'LL GO INSTANTLY BLIND!

The only star that is close enough is the Sun...you can look at the surface of the Sun with a special filter on the front of your telescope, needed to cut the brightness down to a tolerable level. All the other stars are so far away that they only appear as points of light. What we actually look at with telescopes are the Moon, the planets, clusters of stars, nebulae, and galaxies.

No, that would blind you almost instantly and permanently for the rest of your life.

The only way to safely view the surface of a star is by looking at the sun with a SOLAR FILTER especially designed to view the sun safely. There are may types of solar filters ranging from Baader film, to glass white-light filters, to specially designed hydrogen-alpha telescopes by Coronado called Personal Solar Telescopes (PST)

The Sun, yes, with proper filtering. The Sun is a fascinating object to observe, but you have to do it properly.

Any other star, no.

Off topic but anyway, a star doesn't have a surface really, it's just made up of gas/plasma or whatever and held together by gravity =]

Only one, the Sun. All the other stars are so distant that they will only be points of light.

I have a nice 8" reflector and I can make out the discs of the Galilean moons, but the stars are just points of light...

The bigger the telescope, the more light it can gather, which means finer detail can be observed...

It looks like somewhere along the way you got shortchanged an eyepiece. All Meade scopes come with a 25mm or 26mm eyepiece, and that's the one you should be using 99% of the time. You might take it back to where you bought it and tell them the package they sold you is incomplete, or try contacting Meade. Failing that, try to find a local astronomy store and see if they have any 25mm eyepieces; many telescope buyers trade these in for better eyepieces, and they have just about zero resale value, since virtually every telescope on the market comes with one. Forget the Barlow lens...it is poor quality and will only make your problems worse. As others have said, Mars is an extremely difficult target because of its tiny size. Even when it was at its closest in 2003, many people looking through my telescope (which is a large and powerful one) were disappointed. You'll do better with Jupiter just after sunset (but it's disappearing fast behind the Sun) or Venus in the morning sky.

As mentioned....Stars have no real surface and you would be blind for looking at a star. Trying looking at the sun and you wll see what happens. Plus you are giving us limited information. Which telescope is it?? What kind? If you are talking about a regular telescope that you gonna spend $50 on it, its a waste of money, you are paying more for the materials than the quality of the telescope.
