Dark and Quiet Skies for Science and Society – II Implementing the
recommendations

The Conference “Dark and Quiet Skies for Science and Society”, jointly
organized by the United Nations Office for Outer Space Affairs (UNOOSA),
the Government of Spain and the International Astronomical Union (IAU),
should have taken place in October 2020, but, because of the COVID-19
pandemic, it has been postponed and is now scheduled in Santa Cruz de La
Palma, Canary Islands, Spain, from 3 to 7 October 2021.

However, because of the urgency to protect the right of humankind to access
an uncontaminated night sky, both for its intrinsic cultural value and for
the progress of science, the organizers decided to hold an on-line
Workshop, on the same theme as the originally planned Conference.

The rationale for the Workshop and Conference relates to exponential
deployments of technological developments, like urban illumination by LED,
the large constellations of satellites in low Earth orbit and the high
power radio transmission, which are creating unprecedented threats to the
visibility of the pristine night sky and call for effective and prompt
mitigating measures before the damage may become irreversible.

The on-line Workshop in 2020
<https://www.unoosa.org/oosa/en/ourwork/psa/schedule/2020/2020_dark_skies.html>was
a huge success, with more than 950 registered participants who actively
contributed to reviewing a comprehensive Report
<https://www.iau.org/static/publications/dqskies-book-29-12-20.pdf>,
prepared in draft form by 85 international experts and distributed in
advance to all participants. The Report addresses 5 topics: dark sky oases,
optical astronomy, impact of artificial light on the bio-environment,
satellite constellations and radio astronomy. For each topic, a number of
recommendations have been proposed aimed at mitigating the impact of the
various causes of interference.

Starting from the thorough analysis of the Report, the current Conference
will now focus on the implementation of its recommendations, in particular
identifying both the technical and political actions needed for their
effective realization, as well as which stakeholders and partners would
need to collaborate to implement a satisfactory solution for the
preservation of a dark and quiet skies.The programme of the Conference
includes invited talks as well as contributed papers selected through a
call for abstracts. Following the very positive experience of the on-line
Workshop, three Working Groups on the main sources of interference
(Artificial Light At Night, Satellite Constellations and Radio
Transmission) will prepare critical analyses of the various implementation
processes that will be presented at the Conference. Information about the
possibility of participating in the activity of the Working Groups will be
published on this page by the end of June 2021. Registering for the
conference (no fee) is available here

.

Please note that attendance physically in La Palma will be limited and a
webcast will be available for anyone unable to travel. For presenters who
are unable to fund their travel costs, limited subsidies can be applied for
through the registration form.
