To subtract the polynomials $$ 6y^2 - 9y + 9 $$ from $$ 9y^2 + 9y + 19 $$, we can follow these steps:

1. **Write the polynomials in vertical form**:
   $$
   \begin{array}{r}
   9y^2 + 9y + 19 \
   - (6y^2 - 9y + 9) \
   \hline
   \end{array}
   $$

2. **Distribute the negative sign** to the second polynomial:
   $$
   9y^2 + 9y + 19 - 6y^2 + 9y - 9
   $$

3. **Combine like terms**:
   - For $$ y^2 $$ terms: $$ 9y^2 - 6y^2 = 3y^2 $$
   - For $$ y $$ terms: $$ 9y + 9y = 18y $$
   - For constant terms: $$ 19 - 9 = 10 $$

4. **Write the final simplified expression**:
   $$
   3y^2 + 18y + 10
   $$

Thus, the result of subtracting $$ 6y^2 - 9y + 9 $$ from $$ 9y^2 + 9y + 19 $$ is:
$$
\boxed{3y^2 + 18y + 10}
$$
The result of subtracting $$ 6y^2 - 9y + 9 $$ from $$ 9y^2 + 9y + 19 $$ is $$ 3y^2 + 18y + 10 $$.
