BEIJING, Jan. 21 ( Xinhua) — According tomedia reports, the latest observations by astronomers show that the young, bright star of Betelgeuse has been behaving strangely recently and is suddenly darkening, a sign that it is likely to explode, and that the red star is about to evolve into a new phase.
Scientists have observed that Betelgeuse is suddenly darkening, a sign that the star is about to explode, and that the red giant is about to evolve into a new phase
Since October 2018, the brightness of Sage IV has dropped sharply, and is now 2.5 times brighter than usual, and it is once the ninth brightest star in the night sky and has fallen to the 23rd brightest star, and astronomers have been watching The Suju in close keeping watching for decades, measuring its changes continuously since 1980.
In the past 50 years, Sansi has never darkened so quickly, which means it is currently on the verge of some extraordinary event. The reason for the evolution of supernovae is usually at the deepest point of the star, and because of the sheer size of The Four, we have no idea what’s going on inside it.
This could be a prelude to a supernova.
The sage four is a star on the shoulder of the Orion constellation, which is very strange, and looks like a bow-wielding hunter in the night sky, with its name derived from the Arabic word for “orion.”
The star, about 700 light-years from Earth, is one of the nearest neighbors in the Milky Way, and is unique in that it is very close to Earth. The shochu is probably the most likely candidate for supernovae from neighboring Earth, which is about 9 million years old, and larger stars like Sage IV usually live no longer than 10 million years, although not long enough to reach the end of their lives, but we won’t see it explode in our lifetimes. It is likely to explode in the next 20-30 million years.
This is a variable star, which means that it darkens and brightens regularly, with a period of about 420 days, and has been in the normal period of darkening for the past few months, but significantly faster than in previous years. According to the mathematical model, the dimmed process of sage four will end in mid-January 2020, but The four often follow their own rules of operation.
If the four-day explosion, it will be very bright enough to observe its brightness during the day, which will mean that we are on the edge of a space light show, and once the star explodes, it will have some effect on The Earth.
When the four explosions, its core will quickly fuse various elements, and if the star burns to form an iron core, its core elements will not fuse, the core will quickly collapse to form a supernova. At this point, the red superstar will release an energetic blue glow for 3-4 months, then disappear over a period of about a year, and from Earth’s perspective, it will be a very bright star during the day.
The Four Explosions will not have a direct impact on life on Earth, but ultraviolet radiation from space explosions can scorch ozone in the Earth’s atmosphere. For years, The Four has been “behaving strangely”, and in 2009 Charles Townes, a Nobel laureate, said he and his colleagues were troubled by a 15 per cent reduction in the size of The Four since the mid-1990s, as stars tend to brighten up as they shrink in size. But the brightness of the four stay is gradually darkening.
Over the past few months, Sacebu Iv has been even more distinctive, with many astronomers speculating that it could change dramatically. The four could eventually turn into a very small bright star, and may even turn into a black hole, and it will be very shocked if it explodes. (Ye Ding Cheng)
