Antares is a really really big star. The supergiant would easily engulf the orbit of Mars if it was located in our own Solar System. But new observations show that its atmosphere extends much farther - 12 times farther! Again, if you put Antares in the Solar System, its atmosphere would extend beyond the orbits of Jupiter, Saturn, out to the orbit of Uranus.
