A continuous spectrum of a star is a broad range of electromagnetic radiation emitted across all wavelengths. It results from the thermal energy of the star's interior, causing atoms to vibrate and emit photons at various energies. Continuous spectra can be used to determine a star's temperature.
There are no exploding stars (supernovae) in our solar system. Supernovae occur in distant parts of the galaxy, outside our solar system. The nearest known supernova to Earth was Supernova 1987A, which was located in the Large Magellanic Cloud, a satellite galaxy to our Milky Way.
Nova. "Exploding stars" were originally called "new stars", which in Latin is "nova stellarum".
Some of the light gets absorbed by the gases, causing them to heat up and emit light themselves. This creates an absorption spectrum with dark lines at specific wavelengths corresponding to the elements present in the star's atmosphere.
An exploding star, also known as a supernova, can emit a variety of colors depending on its composition and the elements involved. Some supernovae appear white or bluish-white, while others can be red, orange, or yellow. The color of a supernova is determined by the temperatures and energies involved in the explosion.
A star's color corresponds to its temperature because of Wien's Law, which states that hotter objects emit more energy at shorter wavelengths (blue light) and cooler objects emit more energy at longer wavelengths (red light). Therefore, a star with a higher temperature will appear bluer, while a star with a lower temperature will appear redder.

Either a neutron star or a black hole.
The color of a star indicates its temperature based on the peak of its blackbody radiation curve. Hotter stars appear blue or white because they emit more energy in shorter wavelengths, while cooler stars appear red because they emit more energy in longer wavelengths. The relationship between a star's color and temperature is known as Wien's law.

That's called a supernova.
Yes, gases can emit radiation. When a gas is heated, it can emit thermal radiation in the form of light. Additionally, certain gases can absorb and emit specific wavelengths of radiation, such as in the process of fluorescence or phosphorescence.
A star emits light. Our Sun is a star.
The thermal radiation spectrum of an 8000 K star would peak at shorter wavelengths (bluer light) compared to a 4000 K star, which would peak at longer wavelengths (redder light). Additionally, the 8000 K star would emit more energy overall at all wavelengths compared to the 4000 K star due to the higher temperature leading to a higher luminosity.
The color of an object can indicate its temperature through a concept known as blackbody radiation. Objects emit light at different wavelengths depending on their temperature. Hotter objects emit shorter, bluer wavelengths, while cooler objects emit longer, redder wavelengths. This is why we often associate blue with high temperatures (like a blue flame) and red with lower temperatures.
Hydrogen emits different wavelengths of light than mercury because each element has a unique arrangement of electrons in its atoms. When electrons in hydrogen atoms move between energy levels, they emit specific wavelengths of light. In contrast, mercury atoms have different electron configurations, leading to the emission of different wavelengths of light.
