The Hubble Space Telescope releases images of the “Little Dumbbell Nebula” during the 34th anniversary of Hubble’s mission.
April 24, 1990 was the first day the Hubble Space Telescope (HST) was launched into space. To carry out a mission to record images and help study various objects in space, including planets, stars, nebulae, and other galaxies outside the Milky Way.
To mark the 34th anniversary of Hubble’s launch, astronomers have imaged the Little Dubbell Nebula, also known as galaxy M76, located 3,400 light-years from Earth in the constellation Perseus.
Scientists have discovered the largest black hole in the Milky Way galaxy.

M76 is a popular target for amateur astronomers. It is identified as a Planetary Nebula (Planetary Nebula), which is a cloud of glowing gas ejected from a dying red giant star that collapses into a dense white dwarf.
Planetary nebulae have nothing to do with planets. The name comes from astronomers in the 1700s using low resolution telescopes and thinking that such objects looked like planets.
The M76 is made up of rings. and there are two leaflets on each side of the opening of the ring. This appearance may be due to the existence of a double companion star at one time.
The star that collapsed into a white dwarf to form the Little Dumbbell Nebula is one of the hottest remnants ever discovered. Its temperature is as hot as 138,000 degrees Celsius, or 24 times the temperature of the sun’s surface. An extremely hot white dwarf star can be seen in the center of the nebula.
The two bubbles we see in the image are hot gases escaping. along the axis of the star’s rotation They are driven by a hurricane-like flow of material from a dying star. which hurtles through space at a speed of 3.2 million kilometers per hour Fast enough to travel from the Earth to the Moon in 7 minutes.
This strong strong wind blows into cooler and slower regions of gas. which are emitted in the first stage of a star’s life cycle When it became a red giant Intense ultraviolet rays cause the gas to glow. The red color comes from nitrogen. and the blue color comes from oxygen.
Over the past 34 years, Hubble has made 1.6 million views of more than 53,000 astronomical objects in ultraviolet light The total data set is more than 184 terabytes, and since 1990 it has been 44,000 scientific papers published about Hubble’s observations.
The space telescope is the most scientifically productive mission in NASA history. Most of Hubble’s discoveries were unexpected, such as supermassive black holes. Atmospheres of exoplanets Gravitational lensing from dark matter The existence of dark energy and the formation of planets among the stars
NASA has the powerful James Webb Space Telescope (JWST) which takes images in the infrared wavelengths. But it is designed to work with Hubble, not replace it.
Therefore, future space probes will involve the interaction of two light waves. This could help expand modern research, such as the composition of exoplanets. The unusual supernova of the heart of a galaxy and the chemistry of a distant universe
