All object at any temperature irradiate radiation, yet, net total energy may be in minus.In example, earth do reflect and irradiate energy to the sun but in total we recieved energy from the sun at approx 1400 W/m2

What objects will emit energy in the universe?
Any object in the universe with a temperature above absolute zero
What happenes to the temperature as the sun s radiant energy toughes it?
I will assume that by "toughes" you mean "touches". However, you still need to clarify what you mean with "it". In general, if radiant energy falls on an object, the tendency is for the object to heat up. However, objects will also emit radiation, at the same time they receive radiation, and it's entirely possible for an object to lose energy faster than it receives energy from sunlight.
What relationship exist between thermal and radiant energy?
Most sources of radiant energy, like the sun or lightbulbs, also emit thermal energy, which is heat.
How does a fireplace emit radiant energy?
In the form of visible and infrared light from the fire.
What device changes radiant energy in electrical energy?
Solar panels change radiant energy into electrical energy. Solar panels contain photovoltaic cells which are comprised of semiconductors which require little energy to emit electrons. The radiant energy contains well.. energy! This energy is stored in the photons, the ''packs'' light or other radiant energy comes in. This photons come in contact with the photovoltaic cells (which would appear as sheets of metal) passes on energy and this added amount of energy causes the material (photovoltaic cells) to emit electrons. The electrons (negative charge) are attracted to a positively charged metal (relative to the incident metal which the photons strike) and are then carried where needed (either stored or used).
Does the sun emit radiant energy?
Yes.
Is lightning a radiant energy?
Radiant energy is a term that is almost exclusively used for electromagnetic energy. When something is hot, it emits radiant energy. The sun is an obvious example, but all object actually emit radiant energy. The hotter the object, the more energy. Sound does carry energy, but it is not electromagnetic. Objects can emit sound and even "radiate" sound, but the term radiant energy is not normally used for sound.

What determines whether an object is a net absorber or a net emitter of radiant energy at a given time?
All substances above absolute zero emit radiant energy. Whether the object emits more than it absorbs depends on its temperature compared to the temperature of its surroundings. An object warmer than its surroundings will usually be a net emitter.

How does the sun emit radiant energy?
As an outcome of nuclear fusion of sun light elements ofDeuteriumand tritium
What will happen to the amount of infrared radiation emit if an objects temperature is increased?
Increase
What type of energy do objects in space emit?
Stars, satellites, and something else
Characteristics of non luminous?
Objects that do not emit or give out light or energy of their own are referred to as non-luminous objects.
