Discover the fascinating cosmic dance of HM Sge, a rare system where a white dwarf and a red giant star defy conventional nova behavior! In this video, we delve into how the white dwarf in HM Sge accumulates material from its red giant companion, creating a breathtaking nova event. Explore recent findings from the Hubble Space Telescope and SOFIA, revealing surprising changes in HM Sge's temperature, brightness, and composition. • HM Sagittae is a dusty-type symbiotic nova in the northern constellation of Sagitta. It was discovered by O. D. Dokuchaeva and colleagues in 1975 when it increased in brightness by six magnitudes. The object displays an emission line spectrum similar to a planetary nebula and was detected in the radio band in 1977. • Don't miss out on this astronomical marvel! • #HMSge #NovaBehavior #WhiteDwarf #RedGiant #HubbleTelescope #SOFIA #Astronomy #SpaceExploration #CosmicWonders • If you enjoyed the video, please like and share it with your friends! • OUTLINE: • 00:00:00 Mysteries of the Universe: HM Sge's Unfading Nova!
