Explanation: This was a sunrise to remember. About a month ago, just before
the dawn of the Sun [4] , an impressive alignment [5]  of celestial objects
was on display to the east. Pictured, brightest and closest to the horizon, is
the Moon [6] . The Moon's orange glow is caused by the scattering away of blue
light [7]  by the intervening atmosphere. Next brightest and next closest to
the horizon is the planet Venus [8] . Compared to the Moon [9] , Venus appears
more blue -- as can (also) be seen in its reflection from the water. Next up
is Jupiter [10] , while the bright object above Jupiter is the star Antares
[11] . Although this display was visible from almost anywhere on planet Earth
[12] , the featured image was taken along a picturesque seashore [13]  near
the city of Syracuse [14] , on the island of Sicily [15] , in the country of
Italy [16] . This month [17] Saturn appears between Venus and Jupiter before
sunrise, while Mars [18]  is visible just after sunset.
