New Moon
The Moon is positioned between the Earth and the Sun, with its illuminated side facing away from us. The Moon is virtually invisible from Earth. This is the start of a new lunar cycle. New moons are the best time for stargazing as there is no moonlight to interfere with faint celestial objects.
Orbital Geometry
The Moon is positioned between the Earth and the Sun (conjunction). The Sun illuminates the far side of the Moon, leaving the near side in complete shadow.
Visibility & Observation
The Moon rises and sets with the Sun, making it invisible in the sky. This is the optimal time for deep-sky observations as there is zero moonlight interference.
Tidal Effects
New moons produce spring tides — the highest high tides and lowest low tides — because the gravitational forces of the Sun and Moon are aligned.
