The number of supernova explosions does not correspond to the predictions of astrophysicists, perhaps this is due to
In a new study, the authors found usingdata from NASA's Spitzer telescope five supernovae that have not previously been detected in optical light. Spitzer processes information about the universe in infrared light, which penetrates clouds of dust, blocking optical light from our eyes, and emitted most brightly by supernovae without dimming.
To find hidden supernovae, researchersstudied Spitzer observations of 40 dusty galaxies. And they found out that supernovae do form as often as scientists predict, but not all explosions can be detected and observed.
As a result of studying data from SpitzerIt turned out that scientists miss up to half of stellar explosions. It's all about the dust that galaxies contain: it absorbs and scatters optical and ultraviolet light, preventing it from reaching telescopes. Therefore, researchers have long come to the conclusion that the missing supernovae, which are not observed by telescopes, are still alive, just not visible behind clouds of dust.
Types of supernovae discovered by spaceSpitzer telescope are known as “core collapse supernovae.” These processes involve giant stars whose mass is at least eight times the mass of our Sun. As they age, their cores fill with iron. And swollen stars are no longer able to produce enough energy to resist their own gravity. So their cores end up being destroyed suddenly.
As a result, such stars are brokeninto smithereens and scatter the newly formed chemical elements throughout space. And the “heavy” elements produced, such as metals, are critical to the creation of planets, such as our Earth, as well as living things.
