In honor of the 34th anniversary of its mission, the renowned Hubble Space Telescope has gifted the world a stunning image of the Little Dumbbell Nebula, also known as Messier 76 (M76). This fascinating planetary nebula is the remnants of a dying red giant star, shedding its outer layers to reveal a hot and dense core destined to become a white dwarf. The Little Dumbbell Nebula earns its nickname due to its distinct shape, resembling a dumbbell with a central bar and rounded lobes at each end.
Since its debut in April 1990, Hubble has performed 1.6 million observations of beyond 53,000 celestial bodies. The telescope has been instrumental in groundbreaking discoveries that were not even speculated prior to its launch, such as the verification of supermassive black holes, characterizing exoplanetary atmospheres, uncovering the effects of dark matter through gravitational lensing, unmasking the enigmatic dark energy, and revealing the prevalence of planetary formation in various star systems.
