Question

How have scientists proved that supernova explosions occur?

a. Bursts of gamma rays are given off during supernova explosions that can be detected by special instruments

b. ultraviolet rays produced when a supernova explodes are detected on earth using special sensors

c.photons of light travel to earth, allowing astronomers to see the explosion through a telescope

d. infrared rays emitted by a supernova explosion allow scientist to create a thermogram of the event

Answer 1

Proof of some processes in the universe involve the emission of the highest levels of radiant energy.

So the answer would be: Bursts of gamma rays are given off during supernova explosions that can be detected by special instruments.

Answer 2

C) photons of light travel to earth, allowing astronomers to see the explosion through a telescope.

Step-by-step explanation:

Historically, human beings observed through telescopes different supernovas such as "SN 1006", "SN 1604" among others, without even knowing their exact nature, it was believed that they were stars with extreme brightness peaks, then they were called novas, without having any distinction with the current meaning of this phenomenon. In 1866, William Huggins first made spectroscopic observations of what was believed to be a nova, discovering that the hydrogen lines were unusual. Huggins was the first to propose a distinction between Nova and Supernova, proposed that the second was a cataclysmic explosion that destroyed or altered the star.
