Black Holes. What are they, and what do the look like? The first thing to know about them is that they can’t be seen by the human eye – or any other eye for that matter. But we know they exist because they consume matter in space and it disappears. To get a glimpse of these invisible things, you can go the New Jersey State Planetarium (205 West State Street in Trenton, NJ).

At 3:00 p.m. every Saturday and Sunday through March 1, the Planetarium will show “Black Holes”, designed for ages 6 to 12. It features state-of-the-art full dome video and offers both traditional sky and full-spectrum laser programs. Alone or with your family, lean back in the spacious reclining seats for about an hour of engaging entertainment.

A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon.
