    How to define moonless night? There is no moon at all during some night? How to calculate and know whether the moon would appear during one night? If the lunar phase is full moon, is it possible
  • the moon - Moonless nights? - Astronomy Stack Exchange
    My husband has told me that there are nights when there is no moon in the sky, because it has risen in the morning and set before dusk I don’t believe him Does this happen?
  • moon phases - A moonless night - Astronomy Stack Exchange
    Depending on how you define 'night', the nights just before and after a new moon are also moonless, because the moon is either too close to the sun to be seen, or sets before twilight ends, or rises after twilight begins
  • the sun - What is the specific term for time of the night when there is . . .
    It's not quite what you're going for, but in observational astronomy the two weeks between third quarter and first quarter are called "dark time" since the moon is up less than half the night You might colloquially use "dark time" to refer to the hours before the moon rises or after the moon has set By contrast "bright time" refers to the weeks between first and third quarter

    If refraction was higher during the calculated moonless period above, the moon may have risen briefly This is the longest moonless period I could fine between 2 Jan 2000 and 12 Mar 2016, the time limits of the program I'm using There might be longer moonless periods outside this interval
  • How many stars and galaxies can be seen by the naked eye?
    On a visit to Yosemite in May of 1975 or 1976, I saw a very clear, very dark and moonless night sky that was studded with stars I gazed at the sky for a long time because it was so beautiful, and in that sky I also saw galaxies I don't remember exactly how many galaxies, but there were multiple galaxies
  • Why doesnt it hurt to look at stars? - Astronomy Stack Exchange
    If I stare at the sun, it's bright and blinding However, if I look at a star in the sky, it doesn't hurt What causes this loss of energy that would otherwise damage one's eyes?
  • atmospheric effects - Astronomy Stack Exchange
    Depending on your eyesight, the faintest stars you can see in a perfect environment have an apparent magnitude (brightness) of 6-6 5 (though some people have managed to see magnitude-7) According to this site, that translates into about 10,000 stars As for how it would look, I have seen the sky from the stratosphere (about 3 miles up, in a plane, where there is a lot less atmosphere to worry
