Hubble telescope observation, this is a new planet -like nebula!It is growing

The latest observation, the gas star cloud after the little star declines

Born to death, the end of life?

This planetary nebul contains a intricate mesh structure composed of filament -shaped and nodules

The seemingly quiet gas nebula actually covers many activities deep in the nebula.

In a new photo taken by Hubble Space Telescope, the NGC 6891 Nebula exudes bright light. The observation desk helps scientists to understand more about how this gas star cloud is formed and evolved.

Astronomers call NGC 6891 "planetary nebula". This term originated from the beginning of the telescope technology that people have misunderstood the planet's mistakes. Now we know that this type of nebula is formed after the smaller stars release the gas later in their lives.

The HD -Able Space Telescope shot high -definition image shows that the clouds and nodules of the original white dwarf are wrapped deep in the clouds. The data also shows that the outer gas halo expands faster than the innermost gas halo of the nebula, and the observation results even capture the gas shell in different directions.

In a statement, NASA officials wrote: "According to their movements, astronomers estimate that one of the shells has a history of 4800 years, and the outer layer has a history of about 28,000 years. A series of outbreaks occurred in different times. "

NGC 6891 Nebula glow occurs when the white dwarf electrons are ionized or stripped of electrons in the surrounding hydrogen.

NASA said: "When the exciting electronics and hydrogen atomic nuclear are re -combined, they will release energy in the form of light from high energy state to low energy state.

The Hubble Telescope failed on October 23, and its instrument was slowly recovering. The last maintenance of Hubble was in 2009. With the retirement of the spacecraft, astronauts could no longer be exposed. In other words, this 31 -year -old telescope has a large amount of file data to be processed.

Hubble Space Telescope (usually called HST or Hubble) is a space telescope that was launched to a near -ground track in 1990 and has been running. It is not the first space telescope, but it is one of the largest and most wide telescopes. It is famous for its important research tools and astronomy public relations benefits. Hubble telescope is named after the name of astronomer Edwin Hubble, and the Connpton Gamma Radial Observatory (1991-2000), the Chandra X-ray Observatory (1999 to the present), and the Spiezer Space Telescope (2003 -2020) Together, the Space Telescope Science Research Institute (STSCI), one of the great observatorys of the Astronum Astronum Agency (STSCI), chose Hubble's goals and processed the results data until the Gedad Space Flying Center (GSFC) controlled the spacecraft.

Hubble telescope has a mirror of 2.4 meters (7 feet 10 inches) on one side. Its five main instruments can observe the ultraviolet, visible light and near infrared areas in the electromagnetic wave spectrum. Hubble's orbit is outside the earth's atmosphere, which enables it to capture ultra -high resolution images under the background of much lower telescope. It has recorded some of the most detailed visible light images that allow us to go deep into space. Many observations of Hubble Telescope have brought breakthroughs to celestial physics and determined the expansion rate of the universe.

related information

The Hubble Space Telescope is the space telescope running on the earth's orbit in the name of Astrologist Edwin Hubble. Hubble Telescope receives the instructions of the ground control center and transmits various observation data to the earth through radio. Because it is located on the earth's atmosphere, it has obtained the benefits that the foundation telescope does not have: the image of the image is not disturbed by the turbulence, the vision is excellent, and the background light caused by no atmospheric scattering. Essence

NGC 6891 is a planetary nebula near Dolphin. It was discovered by Scottish astronomer Rove Corps on September 22, 1884. The perspective of NGC 6891 is 0,33 '× 0,30', and the viewing star is 10.5.
