Different!This is a unique white dwarf wreckage. This is really attractive to Hubble

DEM L249 From where, how to generate it, who found it

The incomprehension of Hubble telescope and supernova

According to rumors, DEM L24, located in Damai Zhelun Nebula, may be the wreckage of 1A supernova or white dwarf after the death of white dwarfs

With this new photo taken by Hubble Space Telescope, we can observe the amazing red light when the star explosion.

White dwarfs, also known as type 1A supernova; this type of supernova will develop an active cosmic gas belt after the explosion. This type of supernova is located in Damai Zhelun Nebula (LMC), named DEM L249; Damagelun Xingyun (LMC) is a Milky Way system of the Milky Way system. The satellite dwarf is one of the most galaxies to the earth.

According to NASA, the surviving companion star after the scientists were looking for the white dwarf explosion in the Magellan galaxy.

Astronomers believe that the DEM L249 located in Damai Zhelun galaxy is the wreckage of the 1A supernova or the relic of white dwarfs.

The US Aerospace authorities say that white dwarfs are usually stable, but in the two stars around the two -star system, white dwarfs attract a large amount of substances from its companion through gravity, and it will explode when it reaches the critical quality.

DEM L249 is not an ordinary supernova wreckage. Its predecessor is a huge and relatively young white dwarf.

The Hubble Space Telescope is usually referred to as HST or Hubble; it entered the near -ground track in 1990 and is still in service. Although Hubble Telescope is not the first space telescope, it is one of the largest and multifunctional space telescopes. It is an important research tool in astronomical research and is also very beneficial to public relations.

Hubble telescope is named after astronaut Edwin Hubble's name; Hubble Telescope and Connpton Gama Ritting Observatory (1991–2000), Chandra X -ray Observatory (1999 – Present) Spirzer Space The telescope (2003–2020) is also called the four observatorys of the US Aerospace Agency. [8] Space Telescope Research Institute selected Hubble as a target to deal with the results data from the aircraft controlled by the Goddad Aerospace Center.

Hubble telescope has a 2.4 -meter (7 -foot 10 -inch) mirror on one side. Its five main instruments can observe ultraviolet, visible light and near infrared areas in the electromagnetic spectrum. Hubble running orbit is located outside the earth's atmosphere, which enables it to capture ultra -high resolution images under the background of a much lower telescope. It has recorded some of the most detailed visible light images that enable us to understand space more deeply. Some breakthroughs in celestial physics like the expansion rate of the universe are determined by the observation of the Hubble telescope.

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

The white dwarf, also known as the simplified dwarf, is a star nuclear wreck of a stars mainly composed of electronic simplified substances. The white dwarf has a very high density: its quality is equivalent to the sun, but the volume is similar to the earth. The white dwarf has no nuclear aggregation to generate energy, and the weak brightness comes from thermal radiation of the energy stored energy. It is known that the nearest white dwarf is Sirius B. It is the star of the 8.6 light -year -old star, the companion of Sirius A. At present, there are eight white dwarfs in the 100th star systems closest to the sun.

Supernova is a violent explosion experienced by some stars in the end of its evolution. This explosion is extremely bright. The electromagnetic radiation in the process can often illuminate the entire galaxy where it is, and it may gradually decline for several weeks to several months or even years. During this period, the radiation energy released by a supernova can be comparable to the total radiation energy of the sun in its life.

Damagulun galaxy, also known as Dagelun Cloud, is a satellite galaxy in the galaxy. The distance is about 50,000 seconds. The diameter is about 1/20 of the galaxy, and the number of stars is about 1/10. Although it is larger than most galaxies, it will be regarded as a dwarf galaxy when discussing the galaxy. The form of Damagelun galaxy is similar to irregular galaxies, but there seems to be traces of some spiral structures.
