The scientific community has long been curious about what really happens on the planet Earth. With a new study, 3-D technology is being utilized for providing detailed images and footage of what happens thousands of light-years away from the Milky Way galaxy. This could be the space version of Earth's GPS technology.

According to Physics, Edward F. Schlafly, a Hubble Fellow in the Physics Division of the Department of Energy’s Lawrence Berkeley National Laboratory (or simply Berkeley Lab) and his team look into a dust map which uses the Dark Energy Spectroscopic Instrument (DESI) to map out more than 30 million distant galaxies just like a space GPS.

Schlafly also imparted in an interview with the Berkeley Lab that these distant galaxies give off lights which travel for several years. He then emphasized that it's not just the simple years but they're basically talking about thousand of years. These lights travel for thousand of years before people can see it from Earth and this is because the galaxy dust make these lights scatter in space. These galaxy dusts are also responsible for distorting and altering the colors of the lights in the atmosphere visible on Earth. Schlafly shared that some lights are naturally orange but due to some dust, the distant galaxies may appear to release some red lights. All of these elements can also be seen in the space version GPS.

Schlafly and his team are continuously studying ways on how they can understand this phenomenon of the galaxy and space dust. They will be doing this through the space version GPS and it will be on the basis of the dust's concentration, composition, sizes, and even shapes.

As soon as this mystery behind these dust is solved, scientists can already create a more accurate dust map with precise distances of galaxies from one another. It will work just like the global positioning system or GPS here on Earth but this dust map will allow astronomers gauge the galactic distances further.
