On the left side of the image we see a mysterious wall of dust that Beetlejuice is moving towards. Because the wall does not curve like the shock wave around Beetlejuice, astronomers do not believe it was created by the star itself.
Betelgeuse is one of the most interesting objects to observe, mainly due to the pure red color of the star and mainly because the imagination fills the rest.
This bright red star on Orion's shoulder is a supergiant star that is several tens of times the mass of the Sun, and it may erupt as a supernova every day (although on an astronomical scale, each day can also be extended to a million years). However, when you watch Beetlejuice with a really powerful telescope, such as the European Space Agency's Herschel Telescope, you can see the following: the giant star Beetlejuice with all its glory, is facing a collision of its solar wind with a huge gas cloud in its vicinity.
In this image released this week by the European Space Agency, the star's massive solar wind can be seen creating an arc-shaped shock wave around the star as it spreads through interstellar space at a speed of 30 kilometers per second. Closer to the star, there is an asymmetric structure into which the star pours material in and fills its surroundings like bubbles that randomly collide and explode against each other on the surface of a kettle of boiling water.
It is the interaction between the giant star and its environment that the astronomers sought to reveal in an article titled: "The Enigmatic Nature of the Peripheral Mantle and Shock Wave Surrounding Beetlejuice as Revealed by Herschel.
The researchers, from several European universities, combined data from the Herschel Space Telescope, the GALEX Space Observatory, WISE and even radio wave observations to study Beetlejuice and its surroundings. The study of the star, the shock wave and the asymmetric clumps of matter around it.
On the left side of the image we see a mysterious wall of dust that Beetlejuice is moving towards. Because the wall does not curve like the shock wave around Beetlejuice, astronomers do not believe it was created by the star itself. "The straight bar may be the tip of an interstellar cloud lit by Beetlejuice or a fill of material possibly originating in the galactic magnetic field. Since we do not see the curvatures in the bar, we believe that the dust bar is not directly linked to the activities of the Beetlejuice solar wind in the past.
In any case, Beetlejuice is responsible for illuminating the structure, and the conclusion of the study is that the shock wave will collide with the dust wall in about 5,000 years and the star itself will follow 12,500 years later.
For the news in Universe Today
post Scriptum. The star Beetlejuice was at the center of one of the fanciful theories ahead of December 21, 2012. The fear was that it would explode and the deadly gamma rays would cut the Earth

I heard that it is 420~600 light years away from the Earth, a distance large enough that even if it explodes in the near future, the Earth will not be harmed.
It is too early to predict that the position of the wall is static. It is possible that it moves together with the television, it should be measured
If the wall is static or not, measurements take time and may not be possible to measure at all,
Even if there is some sort of collision, it is not certain that anything will happen, just another thin cloud of gas.
For anything to happen the dust cloud has to collide with the core of the star.

Betelgeuse may end its life as a nova or even a supernova, depending on its unknown mass.
An estimated time for this event is on the order of 150 million years from today, but it is far from being avoided
less. According to what is written here, which is new to me, already today in Telegiuz we will be in an unstable energetic state.
What will happen in a nova explosion, at least it will become the brightest star in the sky. Maybe even as bright as the moon, but that should be answered by astronomers. Hope this radiation will not affect the earth.
just a question …
There is no way that behind the aforementioned wall just like that, we are accidentally in a straight line...
By the way, in the past I heard a rumor that if he ends his life, he may influence us in one way or another.
Is there any kind of truth in this?
Thanks in advance.

Telegeuse is 640 light-years away from here, so it hasn't hit the wall yet
Ir.
Is it possible an optical error that both are not at the same distance?
to Boaz,
No. There is no obstacle for the galaxies to exceed the speed of light, since it is not a movement within space, but a movement that originates from the stretching of space, and relativity does not impose any limitations on this.
But if he's so and so light years away, then he's actually already hit the wall, right?
So why is it reported in the future tense if it is an event that has already happened?
This whole thing is a bit strange
Not related to the above. I have a question.
Einstein said: E=MC2
Hubble said that the galaxies are accelerating away from us.
If this acceleration reaches the speed of light, then according to Einstein the galaxies will not exceed the speed of light but will add more and more matter to their mass.
Is this a third possibility for the end of the universe apart from the theories that exist today of the collapse of the universe or the shutdown of the universe.
Thank you to those who can respond to the above and wake up my eyes.
Thanks
Boaz
Instead of "this bright red star, on Orion's writing" it should be corrected to "this bright red star, on Orion's shoulder"
Let's just hope that the science website will be here to update us when it happens
