Catch the right moment astronomers plan with a detector of neutrinos. Supernova emits them from the very commencement of the explosion, but it can flare up in the infrared or visible light is only a few minutes, hours or days. Chance to see a supernova explosion in infrared light within the Milky Way in the next 50 years is almost 100%, and in the visible range – only 20% or less, according to a paper published in the Astrophysical Journal . Right now, technology has evolved to such an extent that we can learn a lot more about supernovae, if the next one will be able to observe in our galaxy and explore it with all the tools available to us, – said Kristover Kochanek from Ohio State University in Columbus, Ohio (USA).
Thus, within our galaxy, astronomers can study gravitational waves of a supernova. Scientists believe that the galaxy supernovae explode only once or twice in a century, while in other galaxies can be observed every few days. Directly to see them is not easy, in the visible range is preventing from making small particles of soot, but the observations in the infrared range are almost no problem. Catch the right moment astronomers plan with a detector of neutrinos. Supernova emits them from the very beginning of the explosion, but it can flare up in the infrared or visible light is only a few minutes, hours or days.
Scientists plan to improve the accuracy of detection, using gadolinium. If neutrinos flagged with purified water tank in which a small amount of gadolinium dissolved, they first collide with the molecules of water, whereby energy is released and neutrons. Then gadolinium absorbs neutrons and also generates energy. Therefore, we can fix one signal, closely followed by another, which will definitely testify to capture of neutrinos. The problem is that the neutrino is emitted not only supernovae, but the sun or nuclear reactors. Scientists plan to use for the detection of neutrinos from a supernova in the Japanese Super-Kamiokande.
