From early summer to early autumn – from early June to early September – this time of year is considered the best time of year to view the Milky Way, according to the Emirates Astronomical Society. It is midnight in the middle of the sky in mid-July, and in the last few days a picture of the Galaxy River was taken from the sky of the UAE, by astrophotographer Tamim Al-Tamimi, in the far southern regions of the country.

Ibrahim Al-Zarwan, chairman of the board of directors of the Emirates Astronomical Society and a member of the Arab Union for Astronomy and Space Sciences, said the Milky Way is known as a cosmic system that contains numerous stars and nebulae. Gases and dust
