Will the sun really explode in 30 million years’ time?

No, nothing like that will happen in the next 30 million years. But in three BILLION years’ time (so 100 times longer than 30 million years), we might be getting close to a problem. Even then, though, the sun won’t explode. It will expand out into Venus’ orbit and then shrink back down again, maybe to something the size of the Earth.

This question was answered by Ulrich Köhler of the Institute of Planetary Research at the German Aerospace Center (DLR).
