Galaxies, specifically those with active galactic nuclei like quasars and radio galaxies, can emit microwaves as a result of the activity in their cores. This can be due to interactions between supermassive black holes and surrounding matter producing jets of high-energy particles that emit microwaves when they interact with the interstellar medium.
What else can I help you with?
How does the tempeature of an object influence the radiation it emits?
The temperature of an object affects the amount and type of radiation it emits. As temperature increases, the object emits more radiation and at higher frequencies. This relationship is described by Wien's displacement law and the Stefan-Boltzmann law.
Hot object emits less radiation than cool?
This statement is not accurate. A hot object actually emits more radiation than a cool object, according to the Stefan-Boltzmann law. The total radiation emitted by an object is proportional to the fourth power of its temperature.
What object that you can observe using your nose?
A flower is an object that you can observe using your nose, as it emits fragrances that can be smelled.
How does thermal radiation work?
Thermal radiation is the process by which an object emits electromagnetic waves due to its temperature. As the temperature of an object increases, it emits more radiation at shorter wavelengths. This radiation carries energy away from the object in the form of heat.
What determines the kind of wavelength and the amount of radiation that an object emits?
The temperature of an object determines the type of wavelength it emits. An object at a higher temperature emits shorter wavelengths, such as visible light or ultraviolet radiation, while colder objects emit longer wavelengths, like infrared radiation. The amount of radiation emitted is governed by the object's temperature and its emissivity, which is a measure of how efficiently an object can emit radiation.
How are microwaves from space detected and what do they tell us about the beginning of the universe?
Microwaves from space can be detected from the use of radio telescopes. Microwaves have been used to test the big bang theory, and this Cosmic Microwave Background (CMB) radiation is a form of microwave that "fills" the universe, that is almost exactly the same in all directions and is not associated with any star or object. The CMB radiation is recognized to be radiation left over from the big bang, or during the early stages of development of the universe.

What object is made black so that it emits heat?
coal is made black so that it emits light
If an object emits or reflects light?
It can be seen by the eye.
Why is it easier to divert microwaves around an object then to divert light waves?
actually microwaves are easier to bend than light waves because microwaves are larger than light waves

Is color a property of an object?
Yes, color is a property of an object that is determined by the way the object reflects or emits light at different wavelengths.
What kind of object swallows everything and emits radiation?
This question is a contradiction.
Everywhere in the universe this characteristic of an object stays the same?
The mass of an object remains the same everywhere in the universe.
