Hubble telescope image of the Dumbbell Nebula
To celebrate the 34th anniversary of the launch of NASA's Hubble Space Telescope, astronomers captured a snapshot of the Little Dumbbell Nebula, also known as Messier 76, or M76, located 3,400 light-years away in the north polar constellation Perseus. The name "little dumbbell" comes from its shape, which consists of a two-lobed structure of colorful, mottled, glowing balloon-like gases that is compressed around the middle waist. Like an inflated balloon, the lobes expand into space from a dying star seen as a white dot in the center. Ultraviolet radiation from the extremely hot star causes the gases to glow. Red is from nitrogen, blue is from oxygen.
The Hubble Space Telescope (HST for short) is a space observatory orbiting the Earth. It has provided astronomers with the clearest and best view of the universe ever after their long suffering from ground-based telescopes, which stand in the way of their clarity of vision. Many obstacles, whether the Earth’s atmosphere full of dirt and dust or Deceptive visual effects of the Earth's atmosphere that affect the accuracy of the results. The telescope is named after astronomer Edwin Hubble.
