A spectacular and rare celestial occultation is scheduled to happen on the late night of March 20th for selected readers of this column. It’s nothing less than the brief disappearance of the well-known first-magnitude star Regulus in Leo, the Lion—and with it, disruption of its well-known “sickle” asterism marking the head of the Lion!
Due to its great brilliancy and richness, the great French astronomy popularizer Camille Flammarion was fond of calling the winter constellation Orion the "California of the Sky." Aside from the Big Dipper itself, perhaps no other star grouping in the entire heavens is as well known. And it’s at its glorious best on February evenings.
As the brightest of the 88 constellations in the sky, Orion is unmistakable. Simply going outside on a clear winter’s night and looking up, your gaze is immediately riveted on its display of colorful bright stars. The first thing you’ll notice are its two brightest luminaries, Betelgeuse and Rigel. If you think stars don’t have color, think again! The former is a red giant super sun and glows a distinct deep orange in hue. The latter is a blue giant and sparkles like a brilliant celestial diamond.
Nothing gets the attention of a stargazer like hearing the word "telescope" mentioned. This wonderful device makes it possible to journey through space and time without ever leaving home.
