Gemini may explode in a visible event
New details have emerged about the star of the Gemini as scientists believe it will explode violently so that the explosion can be seen from Earth.
It turns out that the Betelgeuse star has mysteriously radiated for several months, and astronomers recently released new images of the star.
The pictures, taken in January and December 2019, by a huge telescope in Chile, show how the star has darkened over the past year.
NASA said the observations sparked a debate about the star's explosion time in a global event, known as the supernova. "During the first five months of 2019, it turns out that" Betelgeus "has actually become somewhat brighter, while it has eased significantly over the past five months. It is possible that this variation is just a normal behavior of this famous variable giant, but the blackout The latter has re-stimulated the debate about how long it might take, before the supernova happened. "
Betelgeuse, located in the constellation Orion about 700 light-years from Earth, could explode in thousands of years in the future.
When that happens, light will appear in the night sky on Earth, as the star emits brighter radiation from the full moon.
NASA said that while this event may seem a little bit frightening, the explosion would not pose any threat to life on Earth.
Scientists at the Southern European Observatory shared the images of Betelgeuse blackout for the first time, as they were taken using the very large telescope on Cerro Baranal in Chile.
The "Star of Gemini" star is a red giant, an incredibly bright type of star with a short shelf life. And it changes almost regularly, which means that its brightness can change
