Yes, we have observed stars forming in regions of space where gas and dust condense under gravity, such as in nebulae. These observations are made using telescopes that can detect infrared radiation, which penetrates the dust clouds where star formation occurs. Stars can form in a few million years or tens of millions of years, depending on their size.
