This artist’s impression shows a sunset seen from the super-Earth Gliese 667 Cc.
The brightest star in the sky is the red dwarf Gliese 667 C, which is part of a triple star system. The other two more distant stars, Gliese 667 A and B appear in the sky to the right.
Astronomers have estimated that there are tens of billions of such rocky worlds orbiting faint red dwarf stars in the Milky Way alone. Caption and image courtesy of the ESO/L. Calçada
The sun was setting behind Germany´s famous Cologne Cathedral.
To achieve a large size of the sun behind the cathedral, the shot was taken from 40km away. The photographer has visited the shooting location the day before to find out the exact position for his shot. — Bernd Proschold
Layers of different temperature in the atmosphere creates a distorted image of the sun when it’s near the horizon.
As the sun’s image sinks through these layers it is miraged into fantastical ever changing shapes. Seconds before the sunset, the Green Flash atmospheric phenomena is visible (note the green light on the sun’s upper limb).
Difficult to observe, the momentary green flash above the rising or setting sun has been documented as a phenomenon caused by the atmospheric bending or refraction of sunlight. Like a weak prism, the Earth’s atmosphere breaks white sunlight into colors, bending red colors slightly and green and blue colors through increasingly larger angles.
