Moon Phases

Eye on the Night Sky, May 14, 2026

Thursday, May 14, 2026

Today:
Gemini, the Twins, are standing on the horizon between west and northwest this evening, Castor on the right and Pollux on the left. It was near the feet of Castor, the name of the brother as well as the star, that in 1781 Sir William Herschel discovered a new planet – the one we now call Uranus.

Friday:
Between the brightest star in the skies this evening, Arcturus, high in the south at 11:30 PM, and the second brightest, Vega, slightly lower in the east, the faint stars of Hercules offer a challenge to view. Many people look for the bowtie pattern, one third of the way from Vega to Arcturus, marking his knees to the upper left, and his shoulders to the lower right.

Saturday:
As the Moon reaches its New phase, permitting dark evening skies, it’s a good time to locate the famous but rather faint constellation, Hercules. Looking due east around 11:10 PM, and on a line between Arcturus high in the southeast and Vega in the east, you may find the “keystone” figure of stars that marks the ancient Greek hero.

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.
