Atmospheric gases not only allow for life on Earth as we know it, but also affect the air we breathe (the air quality) and the climate we live in. • Some gases like carbon dioxide (CO2) and methane (CH4), affect the absorption of terrestrially produced infrared radiation and are call...
The earth's atmosphere is composed of a mixture of gases that we call air. The most abundant of these gases, molecular nitrogen and molecular oxygen, are not being greatly affected by human activities and are unlikely to be so in the foreseeable future. However, many of the other gases, ...
Oceans under the light of moribund stars Luca Maltagliati Research Highlights23 Jan 2025Nature Astronomy Volume: 9, P: 27 A dry interior for Venus suggests the planet was never habitable The composition of Venus’s atmosphere is well known, and is likely being replenished by volcanic gases. An...
Atmospheric oxygenation is critical to the development of Earth’s habitability. Oxygen levels, as shown in Fig.1, were very low (<10–7–10–5of the present atmospheric level [PAL]) for the first half of Earth history and then rose to something like 10–3–10–1 PAL during the Grea...
Gravity pulls the gas molecules towards Earth’s center. The pull of gravity is stronger closer to the center at sea level. Air is denser at sea level where the gravitational pull is greater. Gases at sea level are also compressed by the weight of the atmosphere above them. The force of...
and its evolution, possibly revealing the presence of microbial life billions of years ago. The gas samples, in particular, could offer valuable data on trace gases and the planet’s ancient climate, drawing parallels with Earth’s own atmospheric history and aiding future manned missions ...

The atmosphere is the shroud of gases around the Earth, held in place by gravity. It plays a vital role in making our planet hospitable to life, providing air to breathe and preventing large temperature swings between night and day. The atmosphere is mainly composed of nitrogen (78 percent)...

A portion of the incoming solar radiation is absorbed by gases in the Earth's atmosphere. These gases absorb electromagnetic energy at certain wavelengths; therefore, in some portions of the electromagnetic spectrum very little energy is absorbed (for example, the visible) while in other portions ...
