  1. KNIGHT SKY
    The star trails in this image
    were made by combining
    106 exposures of 25 seconds
    each. They circle above the
    Castle of Noudar, a medieval
    castle in Barrancos, Portugal.
    The smallest trail, that of
    Polaris, is to the upper right.

  1. FERRERO 6
    This faint planetary nebula in
    Cassiopeia wasn’t identified
    until French amateur
    astronomer Laurent Ferrero
    found it in 2013. Its thin,
    bright outer rim indicates
    it is strongly interacting with
    the interstellar medium.

  1. DARK HORSE
    The Seahorse Nebula
    (Barnard 150) is a cloud
    of dust and cold gas in the
    constellation Cepheus the
    King. We see it only because
    of the dense star field behind
    it. B150 stretches across 1°
    in apparent length and lies
    some 1,200 light-years away.

  1. CHECKING IT TWICE
    Sharpless 2–115 is an emission
    nebula in Cygnus, here
    imaged in the Hubble palette.
    Abell 71 (Sh 2–116), the small
    round object at lower right,
    is an emission nebula.
