A tremendously large cloud that blocked the light from a distant star has been found to consist of swirling winds of vaporized metal. Even more curious, the cloud appears to be strangely bound to a mystery body that could be a massive planet or a low-mass star.
Astronomers were first tipped off to the existence of this metallic cloud in September 2024 when a sun-like star, designated J0705+0612 and located around 3,000 light-years away, became 40 times dimmer than usual. This dimming lasted for nine months, before the star returned to its original brightness in May 2025.
