Observations from Hubble Space Telescope, the NASA Infrared Telescope and the Gemini Observatory, reveal that excess haze on Uranus makes it paler than Neptune and that dark spots are caused by a ...

In the mid-1960s, scientists from Caltech, Robert B. Leighton, and Bruce C. Murray theorized about the carbon dioxide in the Martian atmosphere that was discovered on a flyby by Mariner IV. The ...

All evidence points to Mars having had a carbon dioxide-rich atmosphere billions of years ago, but insufficient carbonates in Martian soil challenge this theory. Now, a new study using data from ...

New mapping of the giant planet’s upper atmosphere reveals likely reason why it’s so hot. The upper layers in the atmospheres of gas giants — Saturn, Jupiter, Uranus and Neptune — are hot, just like ...

JACKSONVILLE, Fla. — How many layers do you think there are in our atmosphere? Five! We have five different layers between us and outer space. From the surface up there is the troposphere, the ...

Twice a day, at dusk and just before dawn, a faint layer of sodium and other metals begins sinking down through the atmosphere, about 90 miles high above the city of Boulder, Colorado. The movement ...

The same phenomenon that causes aurorae — the magical curtains of green light often visible from the polar regions of the Earth — causes mesospheric ozone layer depletion. This depletion could have ...

The ozone layer is a part of Earth’s atmosphere that captures some of the Sun’s ultraviolet (UV) light emissions. When the ozone layer is compromised, its ability to absorb radiation weakens, allowing ...

Layers of Atmosphere: The Earth’s atmosphere is like an invisible blanket that surrounds our planet and makes life possible. It protects us from harmful solar radiation, keeps the temperature balanced ...

Discover why astronauts must wear pressurized suits during space travel to ensure safety and protect against vacuum ...
