Russian scientist Vyacheslav Avdeev, a researcher at the Astronomical Space Center, announced that the explosion of the star Betelgeuse (the tenth brightest star in the night sky), which is expected to occur in the next tens or hundreds of thousands of years, will lead to the appearance of a "second moon." Avdeev stated during a lecture at the planetarium in Moscow that "the brightness of the star Betelgeuse will resemble that of the full moon in the sky, being visible during the day and beautiful at night," as reported by "Russia Today" citing the "Novosti" agency. He added that at the end of 2019, one of the brightest stars in the sky was rapidly losing its brightness. At that time, scientists assumed that the star might explode soon. However, it later turned out that a cloud of dust was the cause, as the star's brightness returned to normal after it dissipated. Avdeev concluded his lecture by stating, "In any case, the star will explode within the next tens or hundreds of thousands of years, leading to the appearance of a second moon."
