Its famous word can hit 25 degrees on Wednesday

The body, which has blossomed as a spring flower, can be observed in the sky throughout the night, at its highest levels in the late evening and before dawn.

Even with a simple binoculars, you can observe the new nova discovered in Cassiopeia in the night sky, which, like a primrose, has blossomed in the dark sky of the constellation – read The object was discovered on March 18 by Japanese astronomer Nakamura Yuji with a 135mm telephoto lens at 9.6 degrees of apparent brightness. According to the report, sourced from the specialist portal Sky & Telescope, four days ago, no objects brighter than 13 degrees were seen at that location. However, on March 20, it already shone to 8 degrees, which can actually be seen with a simple 50mm binoculars. The next day, Nova Cassiopeiae 2021 also received its permanent rating as V1405 Cas. The variable star, the constellation Cassiopeia, is located in the star-rich western part of the constellation Cassiopeia, increasing its brightness many times, even hundreds of thousands of times in a short time. The constellation, including the detected object, can be observed in the sky throughout the night. The highest level is visible late at night and before dawn. As they write, classic Novas such as V1405 Cas are narrow binary stars, one of which is a compact white dwarf star and the other is either a sunlike star or a red giant star. The strong gravity of the white dwarf attracts hydrogen from its companion, and the transported gas forms a disk accumulating around the white dwarf. The material then spins in a spiral on the surface of the white dwarf, compressing and heating up to about 10 million kelvin: this temperature is already so high that an explosion can initiate a nuclear fusion. Thus a very small amount of the extracted hydrogen is exhausted, as most of the material is exploded into space in the form of a rapidly expanding envelope. “Observing a nova is always exciting. When we look at one of them through our binoculars, we see the light accompanying the explosion,” the report states. Then the brightness of a faint star increases from fifty to one hundred thousand times in hours. Nova usually lightens, fades, often re-lights
