[kok bisa?] bulan muncul sebelum malam!
Foto ini gw ambil tanggal 31 juli 2009!
Mungkin peristiwa ini sering terjadi tapi tetep aja gw heran kok bisa ya bulan muncul walau matahari belum tenggelam (baca=belum malam)?
Kan gw jadi bingung kalo pas ngajar anak-anak murid. "hayo apa yang ada dimalam hari dan bersinar terang?"
Ada agan-agan yang tahu penjelasannya?
semoga belum pernah ada yang posting!
kalaupun pernah ya maaf lah!
dari bro saladflorida! sayang saya belum bisa kasih cendol! terima kasih aja ya!?

Original Posted By saladflorida►I dig up an astronomy book and find the Moon's relative brightness. The Full Moon has about 1/400,000th the brightness of the Sun. Yet the Full Moon sheds enough light that we can read a newspaper at night. It's over 33,000 times brighter than Sirius, which helps explain why, in the daytime, we don't see Sirius but do see the Moon.
I read that the Moon has one of the lowest reflectivities of all the objects in the Solar System. Curious. It looks bright and white even with an average reflectivity of an asphalt parking lot.
Almost every day in a lunar month, we can see the daytime Moon. The days we cannot are when the Moon is Full, when it's New, and a few days before and after the New Moon.
An exactly Full Moon is invisible (or at least not easily seen) during the day because then the Moon is opposite the Sun with the Earth in between. The Full Moon sets when the Sun rises (except near the poles) so we can't see the Moon during the day. It's below the horizon, shining brilliantly on the other side--the night side--of Earth.
When the Moon is New it will be dark and unseen and, for at least two days either side of the New Moon, the Crescent Moon will be "too faint and close to the Sun to be seen with the naked eye--although it might be glimpsed at sunset," says Robert Massey, astronomer at the Royal Observatory Greenwich.
The Moon is close to Earth and that's why we see bright sunlight reflected from its asphalt-parking-lot surface even in the daytime and even when part of the Moon is in shadow. Step outside on or about the 14th of June, and find the daytime Moon. It's there--a shiny half moon, high and West.
