Question

When we take infrared photos of Jupiter we see that it is glowing brightly with heat. In fact, Jupiter emits more energy (in the form of infrared light) than it receives from the Sun in the form of sunlight. What is the source of most of Jupiter's heat?

Answer 1

Jupiter has an internal heat source.

Step-by-step explanation:

It is believed that most of this heat is the residual (left over) heat from the time when formation of early Solar nebula took place. Jupiter absorbs energy from the Sun in the form of light and the coverts it into heat and later releases this heat in the form of thermal radiation.

It is recorded that Jupiter emits almost twice amount of energy from the amount which it receives from the sun. It is this internal source of energy and sunlight which provide energy to Jupiter's atmosphere.

However, this phenomenon of internal heat source is also seen in other celestial bodies as well such as Saturn, Neptune, Stars, etc.
