The Nebula of the Snowman is shot by Hubble. It is so beautiful!

Exploring the previous life of "Hubble Telescope"

New images can see a large amount of luminous gas.

The huge archive library of Hubble Telescope released a incredible space "Snowman" full of hot gas.

This photo is the snowman nebula, which consists of the gas and dust cloud in the deep air. The sharp eyes of the Hubble Space Telescope captured the target from 6000 light years. Because the light from the gas was very weak, images were rendered in a exposure.

"The launching nebula is a diffuse gas cloud that can absorb the energy of nearby large -quality stars, so as to glow itself," said NASA in a statement about this new picture.

"The radiation of these large -quality stars deprives the electronics of the hydrogen atom in the nebula, which is called ionization," said it. "When the excited electrons recover from high energy state to low energy, they will emit energy in the form of light, so that the gase of the nebula will glow."

This famous telescope was taken when observing large -quality and medium -sized "original stars" or newly formed stars. Officials from the National Space Agency wrote that Hubble telescope used its third -generation wide -area camera to "find hydrogenization of original star ultraviolet ionization and jets from stars and some other characteristics."

Hubble telescope is not in the best state. In late October, due to the synchronization errors of internal communication equipment, the five scientific instruments will not be used.

The research team resumed the use of a high -end sky -patrol camera (ACS) on November 7, and restored the third -generation wide -area camera that took this photo on November 21. It is also the most frequent instrument used by the Hubble telescope.

As ground engineers continue to carefully investigate the failure of the 31 -year -old telescope, its other three instruments are still in a protective "security model". The next step of the Hubble team will study a instrument called "Cosmic Origin Spectrometer", which can observe the far -ultraviolet rays.

Although astronauts visited the Hubble Telescope in five different tasks to complete its repair and upgrade, there were no other visit plans. Its maintenance task depends on the Aerospace Plan of NASA, which is over in 2011.

The Hubble Telescope (usually called HST or Hubble) is a space telescope that launched into a near -ground track in 1990 and is still running. It is not the first space telescope, but it is one of the biggest and most use telescopes. It is both an important research tool and the gospel of astronomical public relations. Hubble Telescope is named after the name of astronomer Edwin Hubble. It is one of the large-scale orbital observatory plan space stations of the National Space Agency. X-ray Observatory (1999 to the present) and Spiezer Space Telescope Observatory (2003-2020). The Space Telescope Science Institute (STSCI) is responsible for selecting the goals of the Hubble telescope and processed the obtained data, while the Goded Space Flight Center Telescope Science Research Institute (GSFC) is responsible for controlling the spacecraft.

Hubble telescope has a 2.4 -meter -long (7 -foot 10 -inch) mirror on one side. Its five main instruments are observed in the ultraviolet, visible and near -infrared bands of the electromagnetic spectrum. Hubble telescope running on the orbit outside the earth's atmosphere, enabling it to greatly reduce the background light than the ground telescope, thereby capturing extremely high resolution images. It took some very detailed visible light images, so we can observe in -depth space. Many observations about Hubble telescope have made breakthroughs in celestial physics, such as determining the expansion speed of the universe.

Space telescope was proposed as early as 1923. Hubble Telescope was funded in the 1970s and was built by the US Aerospace Administration with the funding of the European Space Agency. It was planned to be launched in 1983, but the project was troubled by technical delays, budget issues, and 1986 challengers. The space disaster was eventually launched in 1990, but its main reflex mirror did not rotate normally, resulting in spherical spherical distant telescope mirror mirror. Damage. A maintenance task in 1993 revised these optical components and achieved the expected goals.
