Astronomers have created a beautiful atlas of 400,000 galaxies in the cosmic neighbourhood of Milky Way and named it the Siena Galaxy Atlas.
Siena Galaxy Atlas is a digital atlas that was created to get to know our universe better through several of the known galaxies.
It was created using data from three astronomical surveys collected between 2014 and 2017 at Cerro Tololo Inter-American Observatory (CTIO) and Kitt Peak National Observatory (KPNO). Together, these surveys are known as the DESI Legacy Surveys.
It Is dependent on state-of-the-art digital images captured by advanced technology, unlike previous atlases, which relied on antiquated equipment and photographic plates.
As it is built on the images captured with highly sensitive instruments, it boasts the most accurate data.
It is also the first cosmic atlas to feature the light profiles of galaxies - a curve that describes how the brightness of the galaxy changes from its brightest point to its dimmest.
