Betelgeuse Yıldızı Sandığımız Gibi Değilmiş!

One of the most familiar stars in the night sky, Betelgeuse has become one of the most discussed stars in astronomy in recent years. What exactly was the “Great Dimming” observed in 2019 and 2020? Was the star truly signaling an imminent supernova, or was it simply hidden behind a massive cloud of dust? In this video, we examine the latest discovery that has changed what we know about Betelgeuse: Siwarha. (In collaboration with ION Information Technologies Inc.)
