The reason for the giant blobs glows brightly in the universe

The reason why the blobs in the universe become bright is due to the formation of new stars within it.

Astronomers at the Center for Astrophysics Research, University of Hertfordshire, England found the cause of the bright colors in the universe , Science Alert reported Sept. 22.

The blobs called Lyman-alpha blob (LAB) emit brilliant ultraviolet light, though not visible to the naked eye but can be detected through modern telescopes.

LAB-1 is the first and most researched color spot. It is actually a relatively young object in the 13.8 billion-year-old universe and about 11.5 billion light-years away.

By observing from many different telescopes along with some modern computer simulations, astronomers conclude that the source of light emitted by the blobs is due to chaos when the star shapes city.

First, the team used the Hubble Space Telescope, the Hawaii-based WMKeck observatory, and the Atacama Large Millimetre / Submillimeter Array (ALMA) telescope in Chile to observe LAB-1. The images showed the disturbance of new stars deep in the hydrogen clouds and small nearby galaxies that are pouring into the material to form stars.

Later, they used telescope data to simulate the computer and pointed out LAB-1's glowing cause. When new stars form inside blobs, they emit strong ultraviolet light. This light is scattered by hydrogen gas, emitting a bright halo.

"It's like a street lamp in a foggy night, you see diffused light because the light is scattered on tiny droplets. In this case, too, a street lamp is a star forming galaxy and The fog is a giant cloud of gas, the galaxy shines things around it, " explains Jim Geach, an astronomer at the University of Hertfordshire, who led the study.

By finding a solution to this mystery, Geach and his colleagues can find out where and how the largest galaxy in the universe is formed."A large elliptical galaxy has formed in LAB-1 and will become the center of a giant galaxy cluster," Geach said.
