Isolation Of Antihydrogen

Wikipedia says CERN has isolated about 38 atoms of antihydrogen and maintained them for over 15 minutes? ... Do you think that is possible???

Whenever you find a claim on wikipedia that you want to verify, follow the sources it cites. That's what they are for.
Here, I've done it for you this time:
http://www.bbc.co.uk/news/science-environment-13666892
http://www.nature.com/nphys/journal/v7/n7/full/nphys2025.html

The last two articles are paywalled, though.

ArXiv has got a number of papers on the subject:

Thanks.

Why would it be impossible?

I thought that anti-matter couldnt be stored inside things made of matter (its opposite) thats why I thought it was impossible..?

If you read the original report on CNN, the 38 atoms of anti-hydrogen were contained in a magnetic trap. These atoms were held in containment long enough for researchers to run experiments several hundred times.

It's not impossible to make anti-matter, given sufficient time and energy; the trick is to store the stuff and keep it from reacting with matter, which is why the magnetic trap is necessary.
