See picture sunrise on a planet other than Earth, "Mars Planet "
"See the sunrise on a planet other than Earth "Mars Planet For the first time, the US Soyuz probe was able to capture the sunset on Mars, more than three yearafter it was launched by NASA.
The only extraterrestrial planet that has been directly seen and photographed by astronauts is the moon's sky. Titan, Mars and Venus are detected indirectly by space probes designed to land on the surface and transfer images to Earth.
The properties of the heavens outside the Earth seem to vary greatly because of a number of factors. If an atmosphere is found outside the Earth, it has a significant influence on visual properties. Atmospheric density and chemical composition can contribute to color variations, as well as opacity (including cloudiness) and the presence of clouds.
For extraterrestrial skies that are not observed directly or indirectly, their appearance can be simulated based on known parameters such as the location of astronomical objects relative to the surface and composition of the atmosphere.
The color of the sunset on Mars tends to turn blue against its color on Earth because of the dust in the red planet's cover, the Washington Post reported.
"Blue is the source of fine dust on the right side of the planet, making the blue light penetrate the atmosphere better," said team member Marc Lemmon. "The color waves are more constant in the direction of the sun than the other colors. Yellow and orange colors appear in the planet's sky, The two colors in the sky of the planet rather than absorbed ».
The agency explained the phenomenon of NASA that the light from the sun must pass at sunset during the atmosphere of the planet for a distance longer than the distance traveled in the middle of the day.
