The two gases that have been added to Earth's atmosphere in large amounts and are believed to contribute significantly to global warming by absorbing infrared radiation are carbon dioxide (CO2) and methane (CH4). Carbon dioxide is primarily released through fossil fuel combustion and deforestation, while methane is emitted from agricultural practices, landfills, and fossil fuel extraction. Both gases enhance the greenhouse effect, leading to an increase in global temperatures. Their rising concentrations are a major concern in climate change discussions.
Black holes are believed to emit something called Hawking radiation.
About 85% of Neptune's atmosphere is believed to be made up of Hydrogen.
The cosmic background radiation is believed to be the remains of the radiation emitted by the Universe when it started to get transparent - when it had cooled down to a temperature of about 3000 kelvin.
Titan's nitrogen-rich atmosphere is believed to be the result of outgassing from its interior, along with the capture of nitrogen and other volatile compounds from the early solar nebula. The lack of substantial geological activity on Titan has allowed the atmosphere to retain these gases over time.
After loss of the hydrogen, helium and other hydrogen-containing gases from early Earth due to the Sun's radiation, primitive Earth was without an atmosphere. The first atmosphere was formed by gases leaking out from the interior of the early Earth, which still goes on today in volcanoes. Without an atmosphere, life would not have formed.
Carbon dioxide and methane are the two gases that have been added to Earth's atmosphere in large amounts and are believed to have increased global warming by absorbing infrared radiation.
Carbon dioxide and methane are the two main gases that have been added to Earth's atmosphere in large amounts due to human activities such as burning fossil fuels and livestock farming. These gases are known as greenhouse gases as they trap heat in the atmosphere, leading to increased global warming by absorbing and trapping infrared radiation.
Oxygen was not plentiful in Earth's early atmosphere. Instead, it is believed that the atmosphere was composed mainly of carbon dioxide, nitrogen, and water vapor. Oxygen levels increased significantly over time due to the process of photosynthesis by early life forms.
It enters our atmosphere through dead animals, tress and any decaying or burning item that lived. It is believed by some that the change in our atmosphere of concentrations of CO@ may be as high as 0.007%. Some feel this number is wildly high.Oceans provide the largest sink for absorbing this CO2 from our air. Forests provide the largest generator for CO2. Man produces roughly 6% of all CO2 in our atmosphere.

That's believed to be a byproduct of volcanism, though the atmosphere is mainly filled with carbon dioxide.

Titan - a moon of Saturn - has a substantial atmosphere comprised of mainly nitrogen.
