50,000 brilliant galaxy strips on 3D universe map

A 3D map is most complete about the universe due to the Two Micron All-Sky Survey program, also called 2MASS, showing that 50,000 brilliant galaxies exist between infrared light in the universe .

The image of 50,000 galaxies as a carpet woven by countless stripes helps scientists better understand how galaxies are formed and developed. The 3D universe map has 50,000 galaxies about 380 million light years from Earth.

These images were used by software engineer Thomas H.Jarrett (NASA) using WISE and Spitzer space telescopes , a support lens of 2MASS , implemented.

On the cosmic map, dark streaks when passing through the center are blocked by dust on the surface of the galaxies. Away from Galactic planet, each small dot represents a galaxy, different colors to clearly see the distance ratio between them.

Blue represents the galaxy near the 2MASS lens, while red is the distant galaxy. The difference between red and blue dots is 0.1.

Many galaxies are close to each other to form clusters and structures of fairly large scale. Master Karen Masters from the University of Portsmouth (UK), presented this 3D space map at the 28th Conference of the American Astronomical Society.

The light of the galaxy is wavelength-lengthened by the spectrum (redshift). The light from the object moving away from us changes to the end of the red, the spectrum is the wavelength of it being extended. As the galaxies get farther away, the red shift becomes redder.

Near-infrared light passing through the dust allows astronomers to see clearly the image in the sky.

According to experts, if there is no 'red shift', 2MASS can only obtain 2D images. In 1990, NASA's telescope for the first time measured redshift, by October 2010 the 2MRS telescope, which reviewed the galaxy, had made better progress in defining galaxies.

' After 10 years of implementation, the survey of 2MASS is a great successor to the legacy of the physicist, Harvard astronomer, who was instrumental in surveying the movement of the Red Galaxy. Once again, interesting things about the galaxy world are known to the world ' - Karen Master shared.
