A team of astronomers has discovered a new class of object which they call "Super Planetary Nebulae." The new objects are unusually strong radio sources. Whereas the existing population of planetary nebulae is found around small stars comparable in size to our Sun, the new population may be the long predicted class of similar shells around heavier stars.
