NAIROBI, Kenya — Skywatchers are in for a celestial spectacle this March as a total lunar eclipse, a rare planetary conjunction, and the vernal equinox take center stage.
Total Lunar Eclipse Turns Moon Red
On March 3, a total lunar eclipse will bathe the Moon in a striking red glow — a phenomenon popularly known as a “blood moon.”
A lunar eclipse occurs only during a full Moon when Earth passes directly between the Sun and the Moon, casting its shadow across the lunar surface.
During a partial eclipse, the Moon moves partly into Earth’s darker central shadow, known as the umbra. In a total lunar eclipse, however, the Sun, Earth, and Moon align precisely, leaving the Moon completely enveloped in shadow.
Despite this alignment, the Moon does not disappear. Instead, it glows orange-red. Earth’s atmosphere bends and scatters sunlight, filtering out shorter blue wavelengths and allowing red hues to illuminate the lunar surface.
The eclipse will be visible from eastern Asia and Australia in the evening, across the Pacific at night, and from most of North and Central America and western South America in the early morning hours.
Venus and Saturn in Close Conjunction
On March 8, the planets Venus and Saturn will appear unusually close together in the evening sky.
The pair will sit about one degree apart — roughly the width of a single finger held at arm’s length. Although they may seem side by side, the two planets are actually separated by nearly a billion miles in space.
A conjunction occurs when two celestial objects appear close together from Earth’s perspective. To spot them, look low toward the western horizon just after sunset.
Vernal Equinox Marks Seasonal Shift
March 20 brings the vernal equinox, a key astronomical milestone.
The equinox occurs when the Sun crosses Earth’s equator while moving from south to north. On this day, both hemispheres receive nearly equal amounts of sunlight. Day and night each last about 12 hours.
Astronomically, this marks the start of spring in the northern hemisphere and autumn in the southern hemisphere.
Moon Phases for March
The lunar cycle continues through its familiar phases this month, from full Moon to waning crescent, new Moon, waxing crescent, and back again.
With a blood-red Moon, a planetary pairing, and perfectly balanced daylight, March offers skywatchers a season of striking celestial events.
