Scientist believe Earth was dominated by gases such as carbon dioxide (its carbon dioxide content could have been as high as 70 percent), water vapor and methane, creating a greenhouse effect that kept the planet much warmer than it is now. This thick and hazy atmosphere shielded the surface...

Dimethyl sulfide, or DMS, is a compound that is produced from the ocean and enters into the Earth's atmosphere. It aids in the formation of clouds in the atmosphere, which help to provide a shield from the sun's rays and which also cool the temperature of the air. Scientists believe th...

The first step would be to warm the planet using certain gases which trap the Sun’s heat in the planet’s atmosphere. With warmth, water and carbon dioxide, simple plants could begin to grow. These plants could slowly make the Mars more suitable for living. It is estimated that the ...
Nice vistas, but what does the Red Planet smell like? (Image credit: NASA/JPL) Robot explorers have found Mars to be a world of sulfur, acids, magnesium, iron and chlorine compounds, all of which are sunbaked and wrapped in a carbon-dioxide-rich atmosphere. But what would this complex...
the Sun's heat in the planet's atmosphere.With warmth,water and carbon dioxide(二氧化碳),simple plants could begin to grow.These plants could slowly make the Mars fit to live on.It is judged that the whole process might take between 100,000and 200,000years.In the meantime,people could ...
This isn't just a huge waste of food and money, but it adds to the amount of carbon dioxide being created in landfills. Moreover, energy conservation is one of themost important things we can do to reduce our carbon footprint. Leaving our electrical on standby wastes energy turn the ...
