One of my favorite song from Swedish artist Vintersorg is Algol, which is about the eponymous star system.

    Algol, demon, capricious your brightness
    shifts from day to day - rises, abates, intesifies
    again, sometimes triumphant and sparkling,
    sometimes pale and faint. For a long time
    we've searched with wonder for the key
    to this mystery, the right element to
    your eager and changing, queer temperament.

    Now we've dispearsed the haze of the riddle:
    you've got a companion on your journey,
    like a slave, a faithful shadow he
    constantly follows you on the desolate
    path, he circles and sneaks quiet around you, closely.

    Never have we seen his guise, dark, parches,
    stiff and cold, but still we know he exists;
    like ashamed he hides behind you - free
    and merry you shine - until he once
    again crawls out of the darkness and
    covers you. And your glare becomes
    pallid and dull, and your mind cloudy.

    [Chorus]

    And similars there are - many Algols
    wanders in the space - maybe even
    more among us on earth. Sunlight spirits
    darkened by a shadow, young princes
    concealed by old slaves, doublesouls,
    divided creatures - a blissful son of the
    light indissolubely linked with a bitter dark demon.

    [Chorus]

His lyrics talk a lot about science in general, astronomy, philosophy and nature. Also, fun trivia: Vintersorg, despite singing mostly black metal, is a primary school teacher.
