Galaxies that emit an abnormally large amount of energy are typically classified as active galactic nuclei (AGN). These galaxies contain supermassive black holes at their centers, which accrete gas and dust, releasing immense amounts of energy in the form of radiation across the electromagnetic spectrum. This makes them some of the most luminous objects in the universe, including types such as quasars and blazars. Their high-energy emissions can outshine the combined light of all their stars.

A galaxy that emits an abnormally large amount of energy in the infrared, radio, and ultraviolet wavelengths is known as an Active Galactic Nucleus (AGN). AGNs are powered by supermassive black holes at their centers, which consume surrounding material, leading to intense radiation across multiple wavelengths. This energy output can outshine the entire galaxy, making AGNs some of the brightest objects in the universe. Examples of AGNs include quasars and Seyfert galaxies.
A gamma ray burster emits an amount of gamma ray energy in one pulse roughly equal all EM radiation energy of a galaxy in a year. So yes.

The amount of light energy an object emits per year depends on its temperature, surface area, and emissivity, following the Stefan-Boltzmann Law. This law states that the total energy radiated per unit surface area is proportional to the fourth power of the object's absolute temperature. For example, a typical star like the Sun emits approximately (3.8 \times 10^{26}) watts, which translates to an enormous amount of light energy over a year. In contrast, a cooler object like a light bulb emits significantly less energy, depending on its wattage and operational time.
As the temperature of a star increases, the amount of light it emits increases. This is because hotter objects emit more energy in the form of light, including higher energy photons in the visible spectrum, leading to a brighter appearance.
A flashlight transforms electrical energy into light energy and a small amount of heat energy. The electrical energy powers the light bulb, which then emits light energy to illuminate its surroundings.
I said SIZE! Look in the dicussion for your answers. Choose one!
When a light is turned on, electrical energy is converted into light energy and heat energy. The electrical energy flows through the light bulb's filament, which then emits light and a small amount of heat as a byproduct.
