Q. Recently, which telescope of NASA's observed the symbiotic system HM Sagittae (HM Sge) in Milky Way Galaxy?
Answer:
Hubble Space Telescope
Notes: NASA's Hubble Space Telescope studied HM Sagittae (HM Sge), a symbiotic binary star system in the Milky Way. It features a white dwarf and a red giant. White dwarfs are remnants of stars that have burned through their nuclear fuel, while red giants are stars in their final evolutionary stage. In HM Sge, material from the red giant forms an accretion disk around the white dwarf after being drawn in by its gravitational pull.
