A new study from the Monthly Notices of the Royal Astronomical Society revealed that there are 219 million stars that can be found in the Milky Way Galaxy.

Astronomers from the University of Hertfordshire said that using the Isaac Newton Telescope (INT) they've been cataloguing the stars for the past ten years.

They charted stars that were brighter that are 1 million times fainter that what the human eye can see, astronomers said.

Using what the astronomers have catalogued, they put together a detailed map of the Galaxy's disk that shows the density of the stars.

This can give astronomers a vivid look into the structure of this vast system that is composed of stars, gas and dust, they added.

Astronomers added a cut-out stellar density map that came from the catalogue that illustrated the view that they obtained.

They believe that maps like these can be useful to test new-generation models of the Milky Way galaxy.

The catalogue named IPHAS DR2 contained the 219 million stars that were summarized in 99 attributes.

IPHAS DR2 is the second catalogue released from the INT Photometric H-alpha Survey of the Northern Galactic Plane.

Astronomers said that the catalogue will give the world access to measurements taken through broad band filters that captured light at the red end of the visible spectrum.

They said that the stellar density map illustrated the longest and reddest wavelength band that was darkened by dust.

The dusts were moderated in a way that it brings out more structural detail compared to maps built at bluer wavelengths, they concluded.
