Our language tenses weren't really designed for distant space phenomena. Should we say Betelgeuse is a red supergiant or was a red supergiant? When we look at the sky it exists "now" for us and there's no way to know if it's exploded since the light that we're seeing now left its surface. And even if we talk about the light that's leaving it in our "now" that's kind of vague since there's no real universal common clock.
