Aotearoa/New Zealand's heritage seems to be wedded to our night sky, from the celestial navigation used by those who came ashore in the first waka, to Captain James Cook and his astronomer Charles Green's observations of the transits of Venus and Mercury here two and a half centuries ago. Do you think this grassroots connection has been lost over time?
Yes. We don't need astronomy to help guide our day-to-day lives anymore, or to help us navigate. Outside science, the night sky has become a hobby for some and an occasional rural curiosity for the rest of us. As cities have become more illuminated we've lost our view of the stars, and I think with that we've lost a really important connection with the environment, animals, and the rest of humanity as a result.
Once you consider that the night sky and its regular yearly pattern is the only thing in the natural world that won't change in our lifetimes, and that this experience is the same for everyone on the planet, you really start to get a sense of it being a roof over our shared humanity. Knowing a bit about astronomy and the night sky is a powerful resource for culture, science, history, art, health, zoology and sheer beauty. But there is a growing dark-sky movement that has recognised what is being lost, and it is awesome to see the recent resurgence in Māori astronomy, sparked by people like the University of Waikato's Dr Rangi Matamua, who puts in a huge amount of effort sharing his tatai arorangi knowledge via social media and lectures. We have some of the darkest skies in the world and I would love to see more New Zealanders spend more time admiring them, which helps lead to their preservation from light pollution.
On that resurgence: we're seeing more people celebrating Matariki each winter, with some suggesting the Māori New Year be observed as a public holiday, or at least given more prominence than other occasions like Guy Fawkes. Is that something you'd like to see?
