Eye on the Night Sky, April 16, 2026

Thursday, April 16, 2026

Today:
Due south this evening at 9:15 PM, the brightest star in Leo, the Lion, Regulus reigns above a large but much less prominent constellation, that of the Water Snake, named Hydra. The snake’s head appears as a collection of stars half-way between Regulus, and Procyon, midway up in the southwest. The snake’s body curves back and forth to the lower left.

Friday:
The steely blue star rising in the north-northeast, low but due northeast at 10:00 PM, is Vega, from the German “Wega”, and from the Arabic “Al Wika”, the “swooping or diving eagle”. In modern times it is the brightest star in Lyra, the Lyre, a harp-like instrument, home to the meteor showers over the next few nights.

Saturday:
Barely past new, the barest of a crescent Moon will follow the setting sun toward the horizon in the west-northwest. Appearing shortly after, barely above to the Moon’s left, will Venus, and above Venus will be the Pleiades, or the Seven Sisters. Although they are faint, and not easy to see in the fading twilight or with the Moon nearby, the Moon is so thin it makes for a delightful sight this evening.

Total Lunar Eclipse
The Moon passes into the Earth’s shadow early Tuesday morning, March 3rd, 2026.
The Moon moves into the Earth’s shadow late at night on Tuesday, March 3rd, just as twilight increases.  By the time the Moon is fully eclipsed, it becomes difficult to see in the brightening twilight, and it sets only 20 minutes after the eclipse is total.

The Earth’s rotation causes the stars, as well as the Moon, to rise in the east and set in the west.  The Moon’s orbital motion, however, goes the opposite way, with the Moon actually moving from west to east, but much, much more slowly.  This means the Moon’s expected motion, lowering toward the western horizon, comes from the Earth’s rotation.  The Moon’s actual orbital motion causes it to move into the Earth’s shadow from lower right to upper left.  This explains why the shadow starts on the Moon’s upper left, and progresses to the lower right.

Lunar eclipses aren’t rare, but they are also not frequent.  The next Total Lunar Eclipse visible here is in June 2029, followed by another in December of 2029.
