木星的黃昏 Light at Dawn.. Sunset on Mars, NASA's Mars Rover Spirit May 19 2005

Peter's processed fake image.. in a hope that we have Mars with enough thickness of atmosphere for life like ours. So we hear the story of Adam & Eve on Mars someday.. :p

The scene seems like 'light at dawn' rather at sunset..

Sunset on Mars
On May 19, 2005, NASA's Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover's 489th Martian day, or sol.Sunset and twilight images are occasionally acquired by the science team to determine how high into the atmosphere the Martian dust extends, and to look for dust or ice clouds. Other images have shown that the twilight glow remains visible, but increasingly fainter, for up to two hours before sunrise or after sunset. The long Martian twilight (compared to Earth's) is caused by sunlight scattered around to the night side of the planet by abundant high altitude dust. Similar long twilights or extra-colorful sunrises and sunsets sometimes occur on Earth when tiny dust grains that are erupted from powerful volcanoes scatter light high in the atmosphere.
