Haunting Photo Shows Hollowed-Out Shell After Two Massive Explosions Eviscerated a Star

For years, scientists suspected that stars could meet them through one punch of successive bangs-but they have never seen visual evidence of this.

This is just a change. Astronomers who use the very large telescope in Chile took the first image of Matt star in a “double process”, leaving behind amazing supernova residue.

The results they reached, published as a new study in the magazine Nature astronomyDeepening our understanding of the astral development of burned stars called white dwarves.

“The explosions of the white dwarves play an important role in astronomy,” the lead author Priam Das, a researcher at the University of New South Wales Canberra, Australia, said in a statement. “However, despite its importance, the long -term puzzle of the exact mechanism that leads to its explosion is still unleashed.”

Once a very huge star – at least one times of the sun burn – through all its fuel, it collapses under its own attractiveness in a powerful explosion known as Supernova.

This is just one way that can happen Supernovas, not everything Among them is the end of the same. Some of the star is completely blurred, but others, if the star is heavy enough, can result from a very thick heart called the neutron star, or even a black hole.

The scene that was filmed by VLT is the work of the so -called Type Ia Supernova, which is produced by a low -mass star that has exhausted all its fuel and left behind residue called a white dwarf. These creatures are more compact and more intense than their original stars, which prevents them from withdrawing the evil gravity.

In bilateral systems, this strong gravity can strip the white dwarf of its star companion if its orbits are close enough. When you accumulate enough of this stolen substance on the surface of the white dwarf, and reaches a point known as the critical mass, it begins a single thermal thermal explosion, but it is incredibly destroyed by wiping the two stars.

This is a typical understanding. Nevertheless, recent research has found evidence that some white dwarves are beaten by two explosions, not one, before going out. In this scenario, astronomers believe that a white dwarf swimming in a cloud of scrambled helium. This unstable helium cloud is the first to explode, which leads to a second An explosion in the heart of the star. And BAM: You have a double Supernova.

It is important in a place that happens before The white dwarf reaches the critical mass. Astronomers have predicted that this double division will lead to a unique visual signature in the form of two separate straws of calcium-new image. If you look closely, you can see that calcium, which was photographed in blue, is already in the arrangement of two shells.

This is “a clear indication that the white dwarves can explode before it reaches the extent of the famous Chandrasrakar, and that the” double separation “mechanism has already occurred in nature,” said co -author Evo Sitten, who made notes while he was at the Heidelberg Institute for Secondary Studies in Germany.

The work is valid for another reason. IA’s gender explosions are “standard candles” used by astronomers as a measure of a measure in the universe, as they shine in a fixed shine. Now we understand more about this.

Das said: “The disclosure of the internal works of such an amazing cosmic explosion is incredibly permissible.”
