Researchers eventually determined the dimming was the result of material being ejected from Betelgeuse, which cooled, absorbing light from much of the star. A similar dimming was seen again this year, but the cause of this recent event may not be the same as last time.<\/p>\n<p id=\"0495\" class=\"gh gi eb ec b gj ie gk gl gm if gn go gp ig gq gr gs ih gt gu gv ii gw gx gz du ey\" data-selectable-paragraph=\"\">\u201cIt\u2019s normally one of the brightest stars in the sky, but we\u2019ve observed two drops in the brightness of Betelgeuse since late 2019.
