Is the word novas the same in Brazilian and European Portuguese?

Yes

The word "novas" is identical in spelling, grammar, and meaning in both Brazilian and European Portuguese. The only difference is pronunciation. In Brazilian Portuguese, the vowels are generally more open and clearly articulated. In Continental (European) Portuguese, unstressed vowels are often reduced, closed, or even neutralized, which can make the word sound more "consonantal" or clipped to a Brazilian ear.
