THE NEW AGE OF EXPLORATION
“Ever since our species left Africa some 60,000 years ago, the urge to push beyond what’s known—to discover new lands and opportunities—has shaped human culture. And that impulse is still strong.” - National Geographic
Life magazine, special edition, 1969.
What is a Quasar?
by Life’s Little Mysteries staff
The word “quasar” refers to a “quasi-stellar radio source.” The first quasars were discovered in the 1960s when astronomers measured their very strong radio emissions. Later, scientists discovered that quasars are actually radio-quiet, with very little radio emission. However, quasars are some of the brightest and most distant objects we can see.
These ultra-bright objects are likely the centers of active galaxies where supermassive black holes reside. As material spirals into the black holes, a large part of the mass is converted to energy. It is this energy that we see. And though smaller than our solar system, a single quasar can outshine an entire galaxy of a hundred billion stars.
To date, astronomers have identified more than a thousand quasars.
