"Milky Way Mapping" has been given unprecedented importance to chart the sun's galactic spiral arm, the Orion Spur or Arm. Research revealed that the Arm 's length measures several times longer than previously reported reaching towards Perseus and Sagittarius Arms.
"Milky Way Mapping" reveals that the spiral galactic region is a gigantic composition of structures uncoiling from the center of the galaxy. Specifically, the Earth's sun's galactic area is known as the Orion Spur or Local Arm.
According to Space, Orion is called as Spur because it is actually composed of dust and gases in between the bigger arms. In addition, "Milky Way Mapping" results shows that the Orion Arm is a stretch of spurs projecting towards the Perseus Arm and a massive branch that is situated in between the Orion & Sagittarius Arms.

"Milky Way Mapping" using various space technologies has attempted to unravel the complexities of the Earth's Galaxy. Gaia scanning has succeeded in generating a detailed 3 dimensional (3D) map of a conglomerate of billions of stars, suns and planets in the Milky Way galaxy, according to Gamenguide.

In "Milky Way Mapping", research was focused on identifying masers or bright spots of radio emissions. Scientists measured movement and distance of Masers from Earth by using a Very Long Baseline Array (VLBA). This 10-telescope component is located in Socorro, New Mexico. Using the VLBA, scientist were able to identify and measure 8 new masers in the Orion Arm.
"Milky Way Mapping" shows that the maser measures 25,000 light years long. Its distance is more than 16,000 light years. A report from Advances shows that the Milky Way has four spiral arms.
"Milky Way Mapping" using the VLBA is limited to the Northern Hemisphere. Hence, there is a need to conduct another VLBA mapping in the Southern Hemisphere to have a complete picture of the Milky Way.
