Near the end of 2019, astronomers watching the red giant Betelgeuse noted how much the star had dimmed, continuing to steadily fade for months.

\\n\\n

It\\u2019s a variable star, and it\\u2019s known to get dimmer and brighter, but the big surprise is that it\\u2019s still continuing to dim, recently passing magnitude 1.56 and still getting dimmer. This is unprecedented in the decades that astronomers have been watching the star.

\\n\\n

The world\\u2019s biggest telescopes are on the case, and the European Southern Observatory released dramatic new images of Betelguese, resolving features on the star\\u2019s surface and surrounding area showing how it\\u2019s dramatically changed over the course of 2019.
