In this podcast extra episode, we’re joined again by The Essex Space Agency’s Phil St Pier as we take another sideways diversion into science fiction movies as we cast a critical eye over the recent big sci-fi blockbusters:
Star Wars: The Last Jedi
Blade Runner 2049
This episode is dedicated to Matt & Ali’s arrival of their daughter Evangeline Rosa Kingsnorth.
There’s trouble in paradise as Christmas evening in the Cydonia bunker turns ugly. Alcohol may be the culprit. But equally, the blame may lie with suffering a whole day of pretending to like one another and f***ing Christmas songs!
So, while tensions rise and arguments flare, Ralph, Paul and Jen run through the memorable space and astronomy events of 2017 and look forward to the treats in store for 2018.
Then there’s the small matter of John’s annual outtake reel specifically designed to embarrass the hosts and push the bounds of decency as far as politeness will allow!

In this podcast extra we begin a series, suggested by listener Sean Smith, of explaining the considerations involved in choosing practical astronomy equipment. This first in the series discusses one of the most important items in your amateur astronomy tool kit: Eyepieces.
This discussion takes in:
- Why eyepieces are important
- The differences between ‘good’ and ‘bad’ eyepieces
- Choosing the right price point
- Our suggestions for good quality cheap and expensive eyepieces
Don’t forget our end of year review and Newtonmass panotmime will be available to download on Christmas Day.
In this podcast extra episode Jeni discusses the recent detection of two colliding neutron stars and their observation in both gravitational waves and all areas of the electromagnetic spectrum.
Jeni chats with Dr Edward Gomez, Education Director at the Las Cumbres Observatory and Cardiff University’s Gravitational Physics Research Group Leader, Professor Patrick Sutton about the historic observations, what we can learn from these events, the future of gravitational wave astronomy and how this new window into the universe can help us improve some of the fundamentals of our knowledge of space and time.
We also put listeners’ questions on these subjects from Raoul Van Eindhoven, @FuzzySemi and @calcomega to Patrick.
In this podcast extra, we discuss the changing value of the Hubble Constant since 2000 – or put more simply, our narrowing down of how quickly the universe is expanding. This discussion takes in:
- The history of the Hubble Constant
- Edwin Hubble’s dreadful scatter plot
- Further attempts to narrow down the universe’s expansion rate
- Why research papers are awesome and accessible to everyone
In this podcast extra episode for the dark sky star party held by the Podcast Crew, we discuss:
- Fighting light pollution by getting local authorities to dim & turn off street lights
- The value of star parties to boosting your practical astronomy knowledge
- What to expect at the Autumn 2017 AstroCamp
- A round up of Ralph, Damien & Paul’s seasonal astronomy targets
In this podcast extra episode we present our full length interview with test pilot, astronaut and lunar module pilot on Apollo 16, General Charlie Duke.
Drawing on this unique set of experiences, we asked Charlie:
- What surprised you or what weren’t you expecting to see on the moon?
- How did having a rover change the way you could explore the moon?
- How much fun was the lunar rover?
- Which was most exciting, being capcom on the 1st moon landing or walking on the moon on Apollo 16?
- Is the proposed 2032 launch window for a human Mars mission achievable?
- Did you see any colour other than grey on the moon?
- Are there any features on Earth you can see from the moon?
- Were you able to see any star fields during the Apollo 16 mission?
Then we turned the interview over to listeners’ questions:
- @BrewsterNorth asked, what do you think of the commercial plans for lunar exploration?
- Gavin Price (@pillarscreatio) asked, how important is the moon as a staging post for Mars?
- David Blanchflower (@Davidbflower) asked, would you return to the moon now?
- @Openmind asked, did your attitude towards humanity and our planet change for having gone to the moon?
- And the now regular Cornwell Question (from @samcornwell): What’s the most expensive thing you’ve ever broken?
In this podcast extra, Jeni recalls her most recent research trip at the Japanese Infrared Survey Facility (IRSF) situated outside Sutherland in South Africa. This research trip continues Jeni’s endeavours to collect exoplanet transit data.
In this episode we cover:
- The IRSF observatory
- The life of a research astronomer
- The heartbeat of professional astronomy equipment
- Future research for Jen
The Interview: On the discovery of only humanity’s third black hole merger by the incredible Laser Interferometry Gravitational wave Observatory (LIGO), Jeni’s speaks with Professor Patrick Sutton, Head of Cardiff University’s Gravitational Physics Group and member of the LIGO Scientific Collaboration who develops new strategies to detect gravitational wave bursts and creates techniques for locating these sources on the sky for modelling and simulations.
In this interview Jeni asks Patrick about:
- The latest gravitational wave detection
- What we can know about these events and the objects that created them
- The strength and weakness of these signals
The Announcement: For a physics deep dive into the analysis, the data and the modelling of the new black hole merger detected by LIGO this month, LIGO Governing Council member Professor Sathyaprakash (Sathya to his friends) delivers the first lecture on this discovery.
Return to the Interview: In this segment we return to Professor Patrick Sutton who tells Jen about:
- The possibilities for future gravitational wave detections
- The most expensive thing he’s ever broken
- And… personal grooming tips??
This podcast extra episode comes from this year’s Big Bang Fair and Jeni & Paul grabbed an interview with a Gaia mission data scientist to talk data and the efforts taken in the less-glamorous, but absolutely critical, background to provide us with the discoveries and refinements we crave from the European Space Agency’s latest space-based astrometry mission.
So while Paul and Jeni were there as the Sirius Space Agency explaining the science behind a mission into space on the Star Stage, they spoke to a post-doctoral researcher at Cambridge University’s Data Processing Centre for the Gaia Mission.
In this interview we bring you:
- the timelines to data capture, recovery, capture and analysis
- the rapid pulication of results from Gaia data
- a surprising discovery about the Milky Way’s satellite galaxies – the Magellanic Clouds
- a new star cluster found hiding behind a star
