The World's First Dark Sky Island - The Isle of Sark

Isle of Sark Nightscape

While researching a topic very close to my heart, namely the night sky and the importance of darkness, I discovered a remarkable destination which has great appeal to stargazers, nature lovers and tourists alike: the small Isle of Sark, in the Channel Islands.

Self governing Sark, has a population of around 550 people. It has no public street lighting or cars and the only form of transport is by bicycle, boat, tractor and foot. Aware of the benefits of preserving their precious night sky and protecting their natural environment, the community embarked on a mission to illuminate their island sensibly and sustainably. As a result, there is no light pollution so the view of the heavens is breathtakingly beautiful at night. It’s also no coincidence residents report low levels of crime and high levels of happiness in their community.

Using innovation to light our world sustainably

Here at www.astredu.nz one of our main goals is to raise awareness about the importance of the night sky and how to protect and preserve natural darkness. We do this not just because we value the Cosmos, but because the night sky is integral to our wellbeing and that of the environment.

We are particularly interested in innovative, energy efficient and environmentally sensitive lighting because the world needs sustainable solutions to overcome light pollution. Best lighting practices are the way forward.

Thankfully, advances in technology offer systems that can meet a wide range of lighting requirements, including those that adapt to changing conditions. This is welcome news because towns and cities can select the best options for their particular needs, instead of following a one size fits all, blanket approach.

Motivated by the UNESCO’s initiative to announce 2015 as the International Year of Light, the AAVSO is celebrating more than a century of commitment to collecting photons in order to study the variable sky. As part of that celebration, a set of activities has been announced, engaging everyone interested in astronomy to share their favorite story, research project, pretty picture, observing experience, or art work. We invite you to join us and share with us your passion for observing the night sky.

Mutual Events of the Satellites of Jupiter, 2014-2015

User Rating: 0 / 5

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

It happens only for a few months every six years, that we can see mutual occultations and eclipses of the Galilean moons of Jupiter. We are presently in such a period but for only a few months more. During a mutual eclipse one satellite passes through the shadow, cast by the Sun, of a second satellite. At an occultation one satellite passes in front of another as seen from the Earth. The precise times of the resulting minimum brightness and the measurement of the reduction in brightness provide useful information of the relative positions of the satellites involved.
Interested? Before you grab a pair of binoculars or a small telescope, first read this whole article, written by the RASNZ occultation specialist.

Are we heading for a new Maunder Minimum?

We are coming out of the current sunspot cycle 24 which will end around 2019. The maximum of this cycle has yet again been well below that of the previous two cycles.

“Some studies show that sunspot magnetic field strengths […] are already close to the minimum needed to sustain sunspots on the solar surface”.
