The “Fate Pair of Spiral Stars” swirls just 150 light years away from Earth. This rare high-mass and compact binary star system stars are on a collision course that should lead to a special kind of supernova. Astronomers hope to one day explode as a Type 1A supernova, which will brighten ten times more than our moon. The findings are detailed in a Research published in the journal on April 4th Natural Astronomy.

What is a Type 1A Supernova?
In space, supernovae are explosions of stars. They bring spectacular explosions of energy and light, which can be very bright, making the galaxy temporarily surpassing the top.
Type 1A Supernova It’s a special type of space explosion. They occur when the dense remaining core of the white dwarf – stars takes on too much mass. The former star cannot withstand its own gravity and cannot explode. According to NASAType 1A supernovae are rare and occur only once every 500 years in the Milky Way. In comparison, General Supernove happens 2-3 times in a century.
Astronomers have been predicting it for a long time White dwarfs on two orbits are responsible for most Type 1A supernova explosions. The pair is in a close orbit, but the heavier of the two theoretically accumulates material from the partner. This pull causes one or both of the stars to become a kaboom.
Our gateway
For the first time, a team of astronomers observed a binary star system in this, destined to end with a Type 1A supernova. New research. The proximity of the stars to us is an extra bonus.
“For many years, large local double-white d-star binary has been predicted, so I was immediately excited when I first found this system with a very high total mass at our galaxy gateway.” said in a statement.
The pair of white dwarves spiral slowly over each other The track takes more than 14 hours to complete. For more than billions of years, gravitational wave radiation spirals two stars inwardly towards each other until the supernova event begins. By then, they are moving so fast that they complete the trajectory in just 30-40 seconds.
The new Star System is also the heaviest type ever confirmed, 1.56 times the mass of our sun. At this size, astronomers say they are destined to explode. However, it is not expected to happen in other cases 23 billion years. Despite being so close to Earth, we are not expected to put our home planet in danger.
“This is [a] Research co-author and Warwick astronomer Ingrid Perisorli said in a statement. “Finding such systems at our galaxy gateways indicates that they must be relatively common, otherwise we had to search for a large number of our galaxies and look further away to encounter them.”

Looking for 23 billion years in the future
in Case of this Star System supernova eventit is expected that the mass will move from one of the white dwarfs to the other dwarfs. According to the teamthe result is a “rare and complex supernova explosion caused by a quadruple explosion.”
In white dwarfs who gain mass, the surface must first explode where the material is accumulated. Its core explodes second, ejecting material in all directions. The material then collides with the other white dwarfs, repeating the entire process of the third and fourth explosions.
All four explosions should be energy levels Approximately 1,000 trillion times the most powerful nuclear bomb of mankind Destroy the stars completely. So 23 billion years later, this supernova looks like a very violent point of light in the night sky. It should be more than 200,000 times brighter than Jupiter, the largest planet in our solar system.
The team is currently investigating the sky to find out the origin points of other Type 1A supernova.
“We’re slowly getting closer to solving the mystery of the origins of the Type 1A explosion,” Perisori said.
