Objects In The Mirror Are Closer Than They Appear

When I look at the star Betelgeuse through my backyard reflecting telescope, it appears to be a reddish-orange point of light. Phys dot org reports the star is smaller and closer than we previously thought. Because it is beginning to show signs that it might go supernova, we don’t want to be too close. It might hold off for 100,000 years, or it may already have blown up.

The new estimate for the distance to Betelgeuse is 530 light-year. That’s probably a safe distance, but the light show will be impressive when it comes.
