Astronomers have captured the unprecedented dimming of Betelgeuse, With a very large ESO telescope (VLT), astronomers captured the unprecedented eclipse of the solar eclipse, the super red giant star in the constellation Orion.
These amazing new images on the surface of the star not only show red fading giants, but also how they change shape.
Betelgeuse is a lighthouse in the night sky for stars, but it started to get dark at the end of last year. At the time of writing, Betelgeuse is around 36% of normal brightness, a change that can be seen even with the naked eye. Astronomers have captured the unprecedented dimming of Betelgeuse.
Lovers and astronomy scientists alike hope to understand more about the unprecedented power outage.
One of the first observations that emerged from his campaign was an amazing new picture on the surface of Betelgeuse, taken with the SPHERE tool at the end of last year.
The team also watched stars with SPHERE in January 2019 before it began to get dark and gave us pictures of Betelgeuse before and after.
In visible light, the image highlights changes in the star, both in brightness and in visible form.
Many astronomy fans are wondering if the Betelgeuse power outage means it will soon explode. Like all super red giants, Betelgeuse will one day become a supernova, but astronomers don’t think it will happen now. They have another hypothesis to explain what causes changes in the shape and brightness of SPHERE images. Astronomers have captured the unprecedented dimming of Betelgeuse.
The two scenarios we are working on are surface cooling due to extreme star activity or dust thrown at us, researchers say.
Of course, our knowledge of red supergiants is still incomplete and this is still ongoing, so it can still be surprising.
Montarges and his team needed VLT at Cerro Paranal in Chile to examine the star more than 700 light years away and to gather information for its darkness.
Another new image taken with the VISIR VIR tool shows infrared light emitted by dust around Betelgeuse in December 2019.
This observation was carried out by a team in Paris, a French observatory which explained that the wavelength of the image was similar to that captured by the heating chamber.
A cloud of dust, which in the VISIR image resembles fire, appears when a star throws its material back into space.
Throughout their lives, red super giants such as Betelgeuse produce and dispose of large amounts of material before they explode as supernovae.
Thanks to modern technology, we can examine these objects in unprecedented detail, hundreds of light years away, solving the puzzle of their great loss.
