A trio of supergiants — red, cool, bright stars at the end of their lives — may be the biggest stars ever identified, astronomers reported on Monday.
All three have diameters of more than 1 billion miles, or 1,500 times the sun’s girth. If they were in the same location as the sun, they would completely engulf Earth and their outer layers would extend to a point between the orbits of Jupiter and Saturn.
