Monthly Meeting December - The Modern Epicycles of Cosmology
2025-12-08 20:00 - 21:00 (Pacific/Auckland) | Stardome Observatory & Planetarium, 670 Manukau Road, Epsom, Auckland, 1345
Cosmology is in crisis. We know very little about dark energy and dark matter, two things that cosmologists believe
are fundamental to the Universe and integral to the standard model of cosmology. With each new set of high-
precision observation, disagreements between data and the standard model grow. This year experiments like the
DESI survey have cast doubt on the nature of dark energy and how the Universe changed over time. Now the lead-
ing suggestions are that the strength of dark energy changes with time, adding yet more mystery to the phenome-
na. While these new models fit the data, are they true, or are they adding more complexity to a flawed concept? In
this talk we will explore the current landscape of cosmology and question the foundational assumptions of modern
cosmology.
Dr Ryan Ridden is a Rutherford Postdoctoral Research Fellow at the University of Canterbury. His research is fo-
cused in the time domain of astronomy and covers a wide range of topics including supernovae, solar system ob-
jects, exoplanets, active galaxies, and cosmology. Ryan is leading the international Cosmic Cataclysms Collabora-
tion, using space telescope data to search for the fastest explosions and variable objects in the Universe. Earlier this
year Ryan was part of a collaboration which used supernova data to test models of the Universe that did not use
dark energy. Alongside research, Ryan has engaged in public outreach and education, frequently giving public lec-
tures and mentoring future scientists.

Practical Astronomy December - The Summer Night Sky
2025-12-15 20:00 - 21:00
This will be one of our seasonal Planetarium sessions. We will use the Planetarium to explore the Summer Night Sky. This is a great way to improve your knowledge of the Summer constellations and learn about some of the deep sky objects to be found in them.

Practical Astronomy February - an Introduction to Astrophotography
2026-02-02 20:00 - 21:00
This talk will cover the basics of Astrophotography including, composition, equipment and processing.
Note the date swap with the February Introduction to Astronomy talk

Monthy Meeting February - From Mars with Love: Postcards from 50 Years of Exploring The Red Planet
2026-02-09 20:00
This meeting will be screening a Gresham College Lecture with Professor Chris Lintott
During the fifty years since the launch of the Viking spacecraft to Mars, our view of the red planet has changed from hostile desert to a world which was once covered in water, and which may just possibly sustain life. Lavishly illustrated with the latest images from the fleet of spacecraft that have explored our neighbour, this lecture considers how Mars’ fate, like that of Earth, was set in the Solar System’s first billion years, and the chaotic environment the process of planet formation produced.
This lecture was recorded by Chris Lintott on the 3rd of December 2025 at Conway Hall, London.
Professor Chris Lintott is a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College. Having been educated at Magdalene College, Cambridge and University College London, his research now ranges from understanding how galaxies form and evolve, to using machine learning to find the most unusual things in the Universe, to predicting the properties of visiting interstellar asteroids. He was the founder of the Zooniverse citizen science platform, which provides opportunities for more than two million online volunteers to contribute to scientific research, and which was the topic of his first book, ‘The Crowd and the Cosmos’. His latest book is ‘Our Accidental Universe’. Professor Lintott is best known for presenting the BBC’s long-running Sky at Night program, and as an accomplished lecturer. Away from work, he cooks, suffers through being a fan of Torquay United and Somerset cricket, and spends time with a rescued lurcher, Mr Max.

Monthly Meeting March 2026 - How can AI help us find exploding stars and Hungry Black Holes?
2026-03-09 20:00 - 21:00
Dr Heloise Stevance
Modern sky surveys can image the entire sky every night. In doing so, they discover new cosmic explosions – from stars collapsing to stars being devoured by black holes. But the sky is vast and the alerts are many – far too many for humans to keep up with. When the Legacy Survey of Space and Time (LSST) begins in 2026, millions of nightly discoveries will flood astronomers. Partnering with experts in sky surveys and applied machine learning, I am developing a Virtual Research Assistant that harnesses A.I. to help experts find the cosmic explosions that made the space dust we come from.
Dr Stevance is a Schmidt AI in Science Fellow at the University of Oxford working with international sky surveys (ATLAS, Vera Rubin) to find extragalactic transients (supernovae, tidal disruption events). She works at the interface between Astronomy and AI, developing “Virtual Research Assistants” to help astronomers find the needles in the cosmic hay stacks. She is an award winning science communicator and early career astrophysicist (Beatrice Tinsley Lecture Prize 2021, Caroline Hearschel Prize 2024), and her talk will be an updated version of her Caroline Herschel Prize Lecture.

Practical Astronomy March - The Autumn Night Sky
2026-03-16 20:00 - 21:00
This will be one of our seasonal Planetarium sessions. We will use the Planetarium to explore the Autumn Night Sky. This is a great way to improve your knowledge of the Autumn constellations and learn about some of the deep sky objects to be found in them.

Monthly Meeting April - Little Red Dots
2026-04-13 20:00 - 21:00
100 years ago this year, Edwin Hubble published the first conclusive evidence that there were galaxies beyond the Milky Way. This lecture, using new results from our latest space telescopes and ground-based instruments, surveys the diversity of systems that we’ve found since, from giant and beautiful spirals to mysterious Little Red Dots.
This lecture was recorded by Chris Lintott on 18th March 2026 at Conway Hall, London.

Practical Astronomy April - Variable Stars
2026-04-20 20:00 - 21:00
Observation of variable stars has a long history with amateur astronomy. We will discuss the types of variable stars and how to observe them to obtain scientifically useful data. This is still a valuable activity even with the large survey telescopes, as amateurs can obtain data for stars that are too bright for the large telescopes, or for certain types of variable stars where changes are happening rapidly, the survey scopes cannot be dedicated for short cadence observing of a single star.
