about full moons | a brief explanation of our moon
We see it almost every day, but many of us don't know much about our mesmerizing moon. It moves our tides, illuminates our nights, and affects our very minds. The power of the moon should not be underestimated, but instead it should be understood.
okay, but what is a full moon exactly?
Well, a full moon is the lunar phase that occurs when the Moon is completely illuminated as seen from the Earth. this occurs when the Moon is in opposition with the Sun (when it is on the opposite side of the Earth from the Sun; more precisely, when the ecliptic longitudes of the Sun and Moon differ by 180 degrees). This means that the hemisphere of the Moon that is facing the Earth (the near side) is almost fully illuminated by the Sun and appears round (while the far side is almost completely unilluminated).
about moon phases | how our moon ebbs and flows
For us, the most exciting time is when the moon is full - we can feel the difference in energy just like you. But it is important to understand the other phases our beautiful moon experiences.
The moon cyclicly goes through a total of nine unique lunar phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Waning Crescent, New Moon, and then it starts all over again.
looking for a more technical answer?
The half of the lunar surface facing the Sun is always sunlit, but the portion of this illuminated hemisphere that is visible to an observer on Earth can vary from about 100% (full moon) to 0% (new moon). The lunar terminator is the boundary between the illuminated and darkened hemispheres. Aside from some craters near the lunar poles such as Shoemaker, all parts of the Moon see around 14.77 days of sunlight followed by 14.77 days of "night" (the "dark side" of the Moon is a reference to radio darkness, not visible light darkness).
about us | what we do, and why we care
At fullmoontonight, we have one goal: to inform the world of its moon's current status. We compile data from multiple, reliable sources across the world so that we are able to cross-reference the lunar phase information we present to our users and make sure it is 100% accurate.
why do we do it?
We don't have a good answer to that question other than our main reason for starting/furthering this website: there is currently no other website that provides the service we offer at our level of accuracy. If you are wondering why we do not "include more stuff", it is because we believe in simplicity, and getting to the point. So, we do.
Its simple: to provide real-time moon phase status information to every part of the map you are looking at. Yep, that's right; the whole wide world.
