Why the moon phase changes
The Moon doesn’t make its own light — we see the half lit by the Sun. As it orbits Earth over about 29.5 days, the angle between the Sun, Earth and Moon changes, so the lit fraction we can see waxes from a thin new-moon sliver to a full disc and wanes back again. The phase shown above for Stony Brook University is computed from the Moon’s position for the city’s exact coordinates.
Moonrise drifts roughly 50 minutes later each night, which is why the Moon keeps a different schedule than the Sun. Near full moon it rises around sunset and is up all night; near new moon it rises and sets with the Sun and is lost in the glare.
Frequently asked
- What is the moon phase in Stony Brook University tonight?
- Tonight's moon phase for Stony Brook University — its name and the percentage of the disc that's lit — is shown at the top of this page, updated from astronomical phase data. The Moon runs through its eight phases over a roughly 29.5-day cycle, from new moon (dark) through full moon (fully lit) and back.
- What time does the moon rise in Stony Brook University tonight?
- Tonight's moonrise and moonset times for Stony Brook University are listed above in local time, computed for the city's exact coordinates. Moonrise shifts roughly 50 minutes later each night, so the Moon climbs the sky on a different schedule than the Sun.
- Why does the moon look bigger near the horizon?
- That's the Moon illusion: the Moon's actual size in the sky barely changes, but the brain reads it as larger when it sits low behind foreground landmarks than when it's high overhead. It looks the same in a photo taken at both heights.
- What is a supermoon?
- A supermoon is a full (or new) moon that happens near perigee — the closest point of the Moon's slightly oval orbit, around 360,000 km or less. A perigee full moon looks a little larger and noticeably brighter than an average full moon.
- When is the next full moon visible from Stony Brook University?
- The next full moon date is shown above, with a link to its dedicated page. A full moon rises around sunset and is visible all night, weather permitting; the moon-viewing score factors in tonight's local cloud cover.
