b. Fog
c. Artificial Light
d. None of the above

ANSWER: Artificial Light
 
Researchers have found that one third of stargazers cannot see the Milky Way at night on account of light pollution from the buildings, street lamps and other artificial lighting on earth according to a fresh study
  • Night time glow of artificial lights affects astronomers as well as casual night sky observers
  • The survey of night sky brightness was created more than a decade ago by Fabio Faichi and colleagues.
  • Researchers from EU and the US and Israel helped Falchi to conduct the research
  • The study has implications for the worldwide transition into LED technology and until careful consideration is given to LED colour and lighting levels, transition could lead to 2-3 fold increase in sky glow on clear nights.
  • In addition to work of astronomers, bright nights affect ecosystems as well as nocturnal organisms
