NASA is waiting for the launch of the James Webb Space Telescope and has developed a number of scientific research and observation programs for it.The telescope will help scientists solve a mystery about why there seems to be more cosmic dust in galaxies than expected. Where the cosmic dust came from is a mystery.

It is important to understand the origin of cosmic dust, which protects stars when they form, and then becomes part of planets, and can contain organic compounds, leading to the birth of life and vital to the function of the universe. A major problem in astronomy is called

In a series of NASA lists, the James Webb Space Telescope will study the dust producing Wolfe Rayet binary. This type of star is very hot, very bright. There is evidence that wolf Rayet stars interact with their companion stars to produce a large amount of dust and form a unique pinwheel pattern when the stars circle each other and collide with the stellar wind.

Astronomers believe that the binary system may have produced most of the dust in a galaxy. The challenges of studying this type of stellar system include the heat generated and the intensity of brightness, and the James Webb Space Telescope's ability to detect mid infrared light can solve these problems, allowing astronomers to study dust and its chemical composition carefully.

Infrared has a longer wavelength than visible light, allowing it to move between dust particles and reach telescopes, providing information to astronomers. NASA currently plans to launch the James Webb Space Telescope in 2021.
