Light Pollution is a form of environmental degradation. The wasteful light from outdoor manmade light sources emitted directly upwards or reflected from the ground can brighten the sky through scattering by clouds, fog, and pollutants like suspended particulates in the atmosphere. Light pollution not only indicates a waste of electric energy and damages both the natural environment and our living environment, it also harms our health and deprives us of the starry night skies. In this talk, I will discuss the current status of light pollution around the world and in Hong Kong. In particular, I will show the wide spread of LED lighting has affected our night sky. The talk will end with various remedies of the problem, such as finding environmentally-friendly lighting to maximize energy efficiency and minimize light pollution. Overseas examples of limiting usage through legislation and establishment of dark sky preserves will also be discussed.

Professional and Amateur Astronomical Observations above the Atacama Desert

 

Jointly organised with Hong Kong Astro Forum, with TSL Foundation as the programme sponsor for Hong Kong Astro Forum.

(To be conducted in English)

Professional and Amateur Astronomical Observations above the Atacama Desert

Speaker:
Mr. Yuri Beletsky (Las Campanas Observatory Scientist)
Date 3-11-2018 (Saturday)
Place: Lecture Hall, Hong Kong Space Museum

Topic 1: A Survey of World Class Observatories in Chile and their Latest Development and Discoveries

Yuri will introduce a few well known observatories in the region from European Southern Observatory (ESO) and other internationally collaborated U.S. observatories with their recent discoveries. The latest ongoing observatory construction projects and how their sites were being chosen will be discussed. He will also share with the attendees what a typical work day of a scientist at the observatories is like.

Time: 2:15 p.m. - 3:45 p.m.

Topic 2: Astrophotography in Atacama Desert

Spending most of his time under the starry sky, Yuri captured many breathtaking nightscapes and the images of the Universe, and becomes an award-winning astrophotographer. His images have been published in various magazines such as Astronomy, Sky & Telescope, National Geographic, Ciel et Espace, and many others.

Time: 4:00 p.m. - 5:30 p.m.

Free admission on a first come, first served basis.
