NJIT's new 1.6-meter clear aperture solar telescope—the largest of its kind in the world—is now operational. The unveiling of this remarkable instrument—said to be the pathfinder for all future, large ground-based telescopes—could not have come at a more auspicious moment for science. This year marks the 400th anniversary of Galileo's telescope that he used to demonstrate that sunspots are indeed on the Sun.
