Web Name: Brighton Astro
Our next meeting is 7pm on Thursday 29th September 2022
Brighton Astro is a place for cosmic enthusiasts from all walks of life to meet up, talk about the universe and gaze at the stars. Every month we host a talk, and the opportunity to go out with our telescopes afterwards - weather permitting!
We're open to everyone, from beginners to experts. So why not join us and look to the stars?
Monthly meet ups
Once a month (usually the final Thursday) we gather for a presentation on an aspect of the universe. Our speakers range from experts in the field to members of the group; you don't need to know a lot when you come, but you'll definitely leave knowing more!
We're always on the lookout for our next speaker, so if you have something to share we'd love to hear from you.
After the meetings you'll sometimes find us on the seafront with our telescopes, or sheltering from the elements in the pub. Brighton Astro is a great place to meet new people, have some fun and learn together.Back to top
First Light with JWST
Thursday 29th September 2022
Dr Stephen Wilkins
Arrive from 7pm for a 7:30pm start
Friends' Meeting House,
Ship Street, Brighton
The James Webb Space Telescope, which launched on Christmas Day 2021, is the long-awaited successor to both the Hubble and Spitzer Space Telescopes. JWST is an international collaboration, featuring strong involvement from the UK. Ultimately thousands of scientists from around the world will use data from JWST to answer a range of scientific questions. JWST will enable an enormous range of science from allowing us to identify the first stars and galaxies to form in the Universe to probing the atmospheres of alien planets. In this talk I'll introduce some of the first observations, and scientific results, from JWST.

Building A Universe In A Box
Galaxies are as diverse and complex as people, however, they evolve over distinctly non-human time scales and their unfathomable size means they can't be poked and prodded in a laboratory. Instead, to unlock the secrets of their formation and evolution, we look out into the Universe using telescopes (such as the Hubble Space Telescope or Webb Space Telescope). Unfortunately, these only provide a (albeit very pretty) snapshot of a galaxy, frozen in time. To truly understand how galaxies evolve we need something else: simulations! But how do these work? How do you take a computer and reproduce a population of galaxies? In this talk, I will show exactly how astrophysicists build these toy Universes, and how they help us understand our own Universe's past, present and future.

Dr Alexandra Loske
The Royal Pavilion & Sussex University
Women and the Moon
The principle of male and female duality has in many cultures and for thousands of years been compared to the juxtaposition of the Sun and the Moon - the two most prominent objects in the sky. In many - but not all - languages and cultures, the Moon is female. Yet, so far, only men have walked on the Moon, and the role of women in lunar culture and exploration has been undervalued. In this talk, Alexandra will provide an enlightening overview of women and the Moon in literature, art, and science, from the ancient to the new, via overlooked female astronomers and strong female characters in science fiction.

Dr Simon Steel,
Deputy Director of the Carl Sagan Center
SETI: The Search for Extra Terrestrial Intelligence
Our guest speaker this month is Dr Simon Steel, Deputy Director of the Carl Sagan Center at SETI (Search for Extra-Terrestrial Intelligence) to discuss his work and the SETI project. This is a unique opportunity to learn about what is arguably the most exciting project in all of space exploration, the search for other intelligence life.

The Search for Intelligent Life in Deep Space
Are there other intelligent beings in the universe? How can modern science try to answer this age-old question? Prepare for a glimpse into the scientific method applied to the search for alien intelligence.
The Search for Extra-Terrestrial Intelligence attempts to discover, once and for all, an answer to the age-old question of whether other intelligent life exists among the stars. This discussion describes how searches for signs of intelligent life are conducted and informed by scientific astronomical considerations. The implications of search results to-date are explored including thought-provoking ideas such as the concept of Galactic colonisation and a possible glimpse of the future with speculation about interstellar travel.

Brighton Astro Xmas space quiz
Back by popular demand... come and join us for a Brighton Astro xmas space quiz!
Don't worry if you don't know people, we'll be putting together teams on the night, so just come along.
A bit of space knowledge may help but it's not essential, we'll try to make sure the teams are evenly matched.

HOYS-CAPS - Hunting Outbursting Young Stars
I would like to introduce to you our observational citizen science project Hunting Outbursting Young Stars with the Centre for Astrophysics and Planetary Science (HOYS-CAPS) at the University of Kent.
The project aims to measure the brightness of young stars in selected young clusters/star forming regions in multiple optical filters over a long (~20yr) time with a high cadence (1-5days). Given weather constraints we aim to do this as a collaboration of amateur astronomers from the UK, Europe and from across the globe. The light-curves we are obtaining will be used to study multiple aspects of the formation of stars and planets. In particular we are aiming to characterise the structures in accretion disk around the young stars in unprecedented detail and to study the mass accretion history of stars. We are of course also keeping an eye out for the most unusually behaved objects.
We have so far 54 people/observatories that are actively participating in the data taking for our 21 targets, and we have obtained ~8800 images. In total our database now contains ~91.5 million brightness measurements of stars. Some of these have already been used in 3 publications with amateurs (if they wish) as co-authors, and several more are in preparation.

Professor Lucie Green
Our Brilliant Sun
110 times wider than Earth; 15 million degrees at its core; an atmosphere so huge that Earth is actually within it: come and meet the star of our solar system. Light takes eight minutes to reach Earth from the surface of the Sun, but its journey within the Sun takes hundreds of thousands of years. This talk will take you from inside the Sun to its surface and onwards to Earth, to discover how the Sun works. Find out how a solar storm can threaten the modern technology that society relies on and learn more of the latest research in solar physics.
Lucie Green is Professor of Physics at the Mullard Space Science Laboratory. She studies the Sun and is particularly interested in the Sun's magnetic field and how solar weather can affect us here on Earth. She is well known for her appearances on Stargazing Live and The Sky at Night.

Melanie Vandenbrouck, Royal Museums Greenwich
Picturing the universe
The winners of the Insight Astronomy Photographer of the Year competition will be announced at Royal Museums Greenwich on 12 September 2019. Long time judge and art curator Melanie Vandenbrouck will be talking about some of her favourites from this and previous years of the world's greatest amateur astrophotography. She will show that you don't necessarily need expensive equipment or deep astronomical knowledge to create inspiring, moving or impressive pictures of the universe. Creativity, an eye for composition, or being there at the right time are sometimes all it takes.

A tunnel to the beginning of time
As astronomy enthusiasts, you may have heard of ways to study the Big Bang using telescopes and space satellites. But is there any other way? CERN, the biggest science laboratory in the world, is trying to do just that. 100m underground at CERN, there's a 27km round tunnel called the Large Hadron Collider, where we're trying to recreate the conditions of the Big Bang here on Earth. This will allow us to tackle really big questions such as: What are the building blocks of matter? What are the forces between them? What happened to antimatter? What's dark matter? What was the early universe like and how did it evolve? What about gravity? Is there anything else we haven't thought of…?

Curating the Moon
Melanie Vandenbrouck is Curator of Art post-1800 at Royal Museums Greenwich. In 2019, she is curating two exhibitions about the Moon to commemorate the 50th anniversary of the Moon Landing. Moonlight at the Hasselblad Foundation (to 22 September), focuses on contemporary lens-based artists responses to the Moon since Apollo. The Moon at Royal Museums Greenwich looks at humanity's long fascination for our cosmic companion. A long-time lover of the Moon, she found a new fascination for astronomy thanks to the Insight Astronomy Photographer of the Year Competition of which she has been a judge since 2013.

Local author David Whitehouse will recount the story of the Apollo moon landing as told by the crew of Apollo 11 and the many other astronauts who paved the way or followed after the first man to walk on the moon, Neil Armstrong, alongside Buzz Aldrin and Michael Collins. Astronauts, engineers, politicians, NASA officials, Soviet rivals - all tell their own story of a great moment of human achievement.
Tuesday 30th April 2019
In physics, quantum refers to the smallest packet of something and, in this meeting, Brighton Astro will be hosting four short but beautifully-formed talks in one evening. Presented by Brighton Astro members, we will cover a wide array of subjects such as supernovae, astro-photography, the Apollo missions and animals in space. A lot of ground will be covered in a short time so hang on to your hats for an information blitz and whirlwind of fun and interest.
Tuesday 26th March 2019
Art inspired by astronomy, physics and maths
Local artist Nick Sayers will talk about his science-inspired interactive art projects, including Cycle The Solar System, Bicycle Drawing Machines and sun-capturing pinhole cameras. He will discuss how - through these works - he has creatively explored astronomy, physics and mathematics, making these abstract subjects more accessible to a wider audience.

The Pleiades: History, myths & science
The Pleiades, in the constellation of Taurus and has been an object of fascination throughout human history.
This lecture starts with a historical overview of the oldest known representations of this glistening cluster of young stars. It goes on to discuss some of the better known myths and legends associated with the group. Drawing on scientific papers, the lecture then lays out some of our current knowledge about the Pleiades including their evolution, properties and the possible fate of this most beautiful open cluster.

Dr Stephen Wilkins, Sussex University
Exploring the End of the Dark Ages
As we look out in to the Universe we also look back in time. Eventually we reach a period of the Universe's history before stars (and galaxies) had formed; these are the Dark Ages. The Dark Ages were brought to an end by the formation of the first stars and super-massive black holes some few hundred million years after the big bang. The identification of these first objects is one of the goals of modern extragalactic astronomy.
While tremendous progress has been made with Hubble, its small mirror and lack of infrared capability limits its ability to probe this critical period of the Universe's history. However, in the next decade a number of new facilities will be coming online that will shine a light on this critical period in the Universe's history. These include: the Webb Telescope, the successor to both the Hubble and Spitzer space observatories due to be launched in 2021; the new generation of "extremely large" ground based telescopes; and the Square Kilometre Array, the next generation radio telescope currently under construction in Australia and South Africa.

Viewing the high redshift Universe (in 3D)
(No 3D glasses necessary!)
I will present some of my research which focuses on the study of very distant (i.e. high redshift) galaxies using 3D integral field spectroscopy in order to better understand how galaxies evolved. High redshift galaxies are of great interest as they give us a direct view into the past allowing us to explore the depths of the early Universe. However studying them is not an easy task as these extremely distant galaxies are very faint and notoriously difficult to detect. But we like a challenge!
I will discuss some of the underlying physics, techniques and the motivations behind these studies, while drawing on my own results for examples.

Professor Stephen Hawking
Professor Stephen Hawking is an internationally renowned scientist. Why is it that someone once given only two years to live in his twenties was still working after most of us would have retired. What drove this extraordinary person towards learning and sharing the great mysteries of the universe for over half a century? This talk aims to provide some background on Prof. Hawking, his life and times, how he became the most famous scientist in the world, and the legacy he leaves behind.

Casting Light on Light
Pollution from lighting has a negative impact on observational astronomy and this impact may well get considerably worse, without opposition. However, it is not just astronomy that it is affected. This presentation will examine the effects and side-effects of lighting.
Paul Marchant is a Chartered Statistician (CStat) of the Royal Statistical Society (RSS) with a PhD in astrophysics. He has served on the Council of the RSS and chaired the Leeds and Bradford RSS Local Group. Since retirement, he holds visiting fellowships at both Leeds Beckett University and the University of Leeds. He was involved in the Loss of the Night Network (LoNNe), an initiative of European Cooperation in Science and Technology (COST) and is an affiliate of the Consortium for Dark Sky Studies, based at the University of Utah. He takes an interest in evidence-based policy generally and sees good statistics as essential in separating ‘the wheat from the chaff'. He has submitted evidence to Select Committee Inquiries into both Research Integrity and Light Pollution … and there is a link! He is sceptical of claims of significant safety benefits of brighter, whiter public lighting, see Marchant P (2017) ‘Why Lighting Claims Might Well Be Wrong', International Journal of Sustainable Lighting 19, 69-74

Clusters of galaxies - the shy giants of the universe
Clusters of Galaxies, when viewed with telescopes on Earth and in space, are amongst the most beautiful objects in the night sky. Theirs is not a benign beauty: they play host to the most violent and energetic explosions in the present-day Universe. This lecture will review the historical contributions of that studies of clusters have made to the theory of Big Bang Cosmology, and also describe how current research into clusters at Sussex is uncovering the mysteries of dark matter, dark energy and black holes.

How To Weigh A Universe
The universe is a wondrous place filled with extraordinary objects. Just as extraordinary is our ability to understand them. In this talk - packed full of stunning visuals and the latest scientific thinking - you'll hear how we're able to put the universe on the scales. To work out what things in space weigh without ever leaving the Earth. We'll meet some of the most colourful and eccentric astronomers in history and marvel at just how much of space we're yet to understand.
Colin is an astronomy speaker and author who has talked to over a third of a million people about the universe, ranging from schools and the public to conferences and businesses.

Cassini's mission to Saturn
A look at the history, science and findings of the Cassini missions since it's launch in 1997 - including stunning images captured across 2 decades of discovery...
Cassini began the first in-depth, up-close study of Saturn and its system of rings and moons in 2004. After its four-year prime mission, it's tour was extended twice.
During the two-year Cassini Equinox Mission, the spacecraft made 60 additional orbits of Saturn, 26 flybys of Titan, seven of Enceladus, and one each of Dione, Rhea and Helene.
And in 2010, the spacecraft began a second, seven-year-long, extended mission called the Cassini Solstice Mission, concluding with 22 deep dives between Saturn's cloud tops and innermost ring before it plunged into the giant planet's atmosphere.

What keeps astronomers awake at night
Astronomy is ridiculously ambitious: we are attempting to chart the history of the entire universe - and everything in it - from the Big Bang to the present day. So far we've done a pretty good job; we know why eclipses happen, how planets form and how stars die. We know about planets around other stars, distant galaxies and even how galaxies clump together to form structures inadequately described as humongous. What I want to do is talk about the gaps, the things we almost know but not quite. I'll try to show you why they are so tough, and how we're attacking them. We call them "open questions" but really they're what have kept astronomers observing and theorising for millennia: they're what keeps us up at night.

Think Universe! (part of the Brighton Science festival)
Mysterious creation myths still influence our culture, but what does science say about the origins of the universe? Join astronomer Dr Francisco Diego for a fascinating talk on the relevance of science to modern culture.
Tuesday 30th January 2018
José Vieira, Sussex University
Cosmology is perhaps best described as "the study of the Universe as a whole". What does the Universe look like at the largest scales? How did it come to be? How will it evolve in the distant future? These are all important questions which cosmology deals with.
In this talk we will briefly review the history of cosmology - from when it was "born" of Einstein's theory of relativity until recent years, when remarkable observational successes have allowed it to mature into a fully-fledged scientific field.

Twenty(ish) ways the universe wants to kill you
The universe is not your friend! You might think that the universe is a nice stable place that has allowed life to develop but we're a freak, a long shot, a straight flush in the poker hand of life and the cosmos stacks the cards against you and we're never more than a statistic away from annihilation.
In this light hearted look at our own extinction Jarvis Brand discusses a range of ways from the small to the large in which the end could come from rogue asteroids and greenhouse effects to the big rip and membrane collision. How dangerous are they and where can we stand at a safe distance to watch the fireworks?
Jarvis Brand (B.Sc. (hons), M.Sc., PGCE) studied Astrophysics and Physics at the University of Birmingham where he was a research associate. He now runs the planetarium for the Observatory Science Centre at Herstmonceux.

Dr Stephen Wilkins, Sussex University
An introduction to Relativity
Einstein's special and general theories of relativity are physical theories regarding the relationship between space and time in addition to being the current description of gravity in modern physics. Since their development in the early 20th century they been subject to intense scrutiny and empirical validation, with the most recent example being the discovery of gravitational waves. Relativity has also drawn significant attention outside the physical sciences because of some of the seemingly counter-intuitive implications such as time dilation and length contraction, concepts which have become science fiction staples. In this talk I'll attempt to provide an accessible introduction to relativity and its implications.

What would the sky look like through eyeballs the size of tennis courts? What could we see if we had radio-wave vision? Come and find out at our next Brighton Astro meet up on Tuesday 27th June where PhD student Dániel Molnár will be talking about the giant machines that allow us to do this, and what we learn from them. In his PhD, he studies all different types of galaxies, from "average" ones to violent and intense so-called active galaxies.

Detecting the most distant galaxies
One of the salient questions in Astronomy is "How far away is it?". As our equipment both literally and philosophically has improved, this question has driven our view of the universe to completely change. From a flat disc in the centre of the universe below a static, unchanging heavens to the modern day view: that the universe is an ever changing mess in which we just happen to be along for the ride. During this talk I'll try to talk about the how measuring distances is done, describe what kinds of celestial objects hold the records for farthest object, and briefly outline how to use a telescope as a time machine.
