It's luminosity is 90,000 - 150,000 times that of the Sun, so it's safe to assume that the total amount of infrared radiation will also be more.
Since its temperature is lower than that of the Sun, the percentage of infrared radiation should also be higher.
The outer layers of Betelgeuse ... the visible part ... are cooler and redder
than the sun, so its relative infrared output is greater than the sun's is.
Clouds do reflect incoming sunlight back into space, as well as retain heat in the lower atmosphere. High clouds tend to have more of a warming effect because it is easier for solar radiation to pass through them, and also because the temperature at which they emit infrared radiation (heat) back to space is much less due to their cold temperature. Conversely, low clouds tend to be optically thick and reflect more solar radiation back to space, causing more of a cooling effect. They also emit more infrared radiation upward because they're emitting at a warmer temperature lower in the atmosphere, further adding to their cooling effect. However, scientists are not yet certain whether the net effect globally is cooling or warming.
Both infrared radiation and light are examples of electro-magnetic radiation and travel at the same speed.
Because such nuclei have stable ratio of protons and neutrons, but some atoms having atomic no less than 82 are also radioactive.
This is because infrared can travel farther with less distortion, i.e., it has less attenuation.
Any object radiates electromagnetic waves - if it is hotter, it will radiate more of it. It's one way to transfer heat from one object to another (the other are conduction, and convection). For objects with a temperature less than several hundred degrees Celsius, this radiation will be infrared.
No, they do not. Because of the technology, LCD televisions emit far less energy than standard televisions and do not emit radiation.
Infrared radiation has less energy (per photon) than visible light.
An LED TV does emit radiation. However, the amount is very small and not considered harmful. The radiation from an LED television is much less than the radiation that was emitted from older television models.
Generally, yes. For example, a hot coil may emit infrared or even red light, and hot iron glows. When cool, however, they do not emit light. The reason is that electrons are given more energy from the heat, so they raise in their location from the atom, and when they return to a stable location they give off light.
No, ice emits thermal radiation. It just emits less than so called room temperature. You need to get down to absolute zero, around -273C, to stop the emission of thermal radiation, which is caused by thermal activity.
Carbon dioxide and other greenhouse gases are opaque to infrared radiation, therefore the less atmosphere there is for an infrared telescope to look through, the more you will be able to see.
Everything emits energy (radiation). Ice, less so than most other natural surfaces.
Its the thermal energy that the Earth emits. Radiation is essentially another word for heat. There is also solar radiation which is simply the heat from the sun. The Earth actually emits far less thermal energy than what is taken in from by the sun and absorbed into the atmosphere. On the other hand there are planets like Jupiter whose surface temperature is mostly comprised of heat from thermal energy instead of solar radiation.
Ultraviolet rays have more energy and a higher frequency, while an Infrared ray is essentially heat, which has less radiation, and a longer wavelength. Also, they are located lower of the Electromagnetic Spectrum.

Lack (or reduced) fission products. Fission products emit most of the harmful radiation in fallout.
Betelgeuse has less than a million years left, which is a very short time for a star.
