2019 Star Stories And Urban Astronomy Dates

I’m delighted to announce the schedule of events for both the Star Stories Programme at Abriachan Forest and the Urban Astronomy evenings at the Merkinch Local Nature Reserve.  Some of these events may be subject to late change so please check back and keep tabs on my Highland Astronomy Facebook page for more details.  I’ll also post Eventbrite links for bookings here and on social media around a month prior to each event.

Star Stories at Abriachan Forest

Now entering its third year, Star Stories returns with another captivating programme of family friendly stargazing and storytelling events.  This year will see the erection of a wooden henge and sundial at the Abriachan site to compliment the program’s leaning towards ancient and observational astronomy.   Further ahead, and as a result of overwhelming feedback, we’re looking to fund an on-site video telescope to enhance the binocular observing and expand the outreach of the events via live streams.  Star Stories is in collaboration with Abriachan Forest Trust and part funded by the STFC’s Spark Award Scheme.

Location:  Arbrichan Forest (A Dark Sky Discovery site)

Oct 5th at 8pm – Ancient Astronomy.  Kicking off the observing season with a night of stargazing, storytelling and ancient astronomy learning (indoor and outdoor).  In collaboration with the Highland Archaeology Festival.  Astronomy outreach:  Stephen Mackintosh.  Storytelling: Clelland McCallum

Nov 23rd at 7pm – Dark Sky Man.  The first ‘Dark of the Moon event’ and another chance to let special guest astronomer and author Dark Sky Man (aka Steve Owens) guide you across the night sky.   Guest astronomer  Steve Owens.  Storytelling: Clelland McCallum .

Dec 11th at 7pm – ‘Astronomy from the Moon:  studying the universe from our nearest neighbour’ is a talk delivered by Professor Martin Hendry of Glasgow University, joining us again in the forest classroom.  We’ll have a full Moon this evening allowing us to observe with video telescope and binoculars.  Guest speaker:  Prof. Martin Hendry.   Astronomy outreach:  Stephen Mackintosh

Dec 21st at 7pm – Winter Solstice Special with guest storyteller and author John Burns.  Celebrate the longest night and the slow return of brighter days with a special dark sky Solstice special with our first ever guest storyteller, author John Burns.  We’ll also have outdoor stargazing and astronomy guiding (weather permitted) or a solstice inspired astronomy talk.  Guest storyteller:  John Burns.  Astronomy Outreach:  Stephen Mackintosh

Jan 10th 7pm – Eclipse Special.  A special night on the astronomy of eclipses with an opportunity to observe a live penumbra eclipse of the Moon via binoculars and video telescope.  Astronomy outreach:  Stephen Mackintosh.  Storytelling: Clelland McCallum

Additional 2020 dates are still being finalised but we’ll have guest talks from Eric Walker of the Highland Astronomical Society in February and local photographer Claire Rehr in March.  The Glasgow Science Centre crew will also return in May for more hands on workshops.

 

Urban Astronomy Evenings at the Merkinch Nature Reserve

Since finding a permanent base of operations at the Sea Cadets Hall in Inverness, the Merkinch Urban Astronomy nights have attracted a growing number of participants.  This year we’ll be inviting some guest speakers and continuing our format of indoor astronomy talks with the additional option of walks to the nature reserve for live observing.  This programme is delivered in partnership with Caroline Snow and Friends of the Merkinch Local Nature Reserve.

Evening meetings:  Sea Cadets Hall, 44 Kessock Rd, Inverness IV3 8AJ.

October 3rd at 8.30pm – Saturn Special.  Opportunities to stargaze and observe Saturn from the local nature reserve and perhaps the setting Moon next to mighty Jupiter.  Guiding by local astronomer Stephen Mackintosh.  If sky conditions are poor we’ll stay indoors for an indoor presentation on Saturn.

November 7th at 8.30pm – Moon Special.  Come and observe the bright waxing gibbous Moon from the grounds of the Merkinch nature reserve.  Indoor Moon talk if skies are poor.

December 19th at 8.30pm – ‘A Telescope isn’t just for Christmas’.  A special Christmas event on getting started with observing, what to buy, what to avoid, where and when to observe.  With local astronomer Stephen Mackintosh.  Outdoor stargazing from the reserve if conditions are clear.

January 16th at 8.30pm – Supernova Special with guest speaker Dr Anthony Luke of UHI talking about the incredible science and chemistry behind exploding stars.  Opportunities for stargazing from the local nature reserve if conditions are clear.

February 20th at 8.30pm – Aurora Special with guest photographer Graham Bradshaw.  Graham will discuss aurora, how to find it and photograph it.  He’ll also share some of his amazing photographs and videos.  Opportunities to observe from the nature reserve if time and weather permits.

March 12th at 8.30pm – Venus Special.  With Venus now a beacon in evening skies we’ll have a special talk on the planet with astronomer Stephen Mackintosh,  Plus opportunities to observe it, and the stars, from the local nature reserve.

Exciting 2019/2020 astronomy programmes are coming together for Star Stories at Abriachan Forest and the Urban Astronomy evenings at the Merkinch Nature Reserve.

Both programmes kick off from 3rd and 5th October.  This year we’re aiming to invite both guest astronomers and storytellers to Abriachan, with author John Burns standing in for Clelland during a special dark sky Solstice event on the 21st December, for example.

Look out for a full list of event dates going up soon, with booking links for the first few.

First Urban Astronomy gathering:  Thursday 3rd October, Inverness

First Star Stories at Abriachan Forest:  Saturday 5th October, in collaboration with Highland Archaeology Festival.

Star Stories is in collaboration with Abriachan Forest Trust (A Dark Sky Discovery Site) with funding support from the Science and Technology Facilities Council.

The Urban Astronomy Evenings are in collaboration with Friends of Merkinch Nature Reserve.

The Stars at Bella

20190802_223609.jpg

Stage all set for my stargazing show Belladrum Tartan Heart Festival.  On both evenings sky conditions were good enough for the show to move outdoors under clearing skies,

The stars were out at Belladrum Tartan Heart Festival last weekend. Not those on stage, but the more distant and ancient ones up in the sky.  I had loads of fun sky guiding outdoors with all the late night merrymaking around us – a markedly different experience to the stillness of SCAPA festival but none the worse for it.  My portable PA came to the rescue and managed to win out against one of the louder music tents across the way and questions and answers were easily fielded.

On both evenings skies started cloudy but partially cleared by about 11.30pm, allowing me to take the show outside for a laser pointer assisted tour of the heavens.

Skies to the north were sufficiently clear to tour the rich pickings around Ursa Major, with its famous double star Mizar and its abundance of celestial pointers, leading to Polaris and many of the other bright stars in the sky

Amidst opening and closing patches of sky we saw red giant Arcturus, Vega, distant Deneb, the stars of Ursa Major, Cassiopeia (both pictured), Cygnus, Lyra and Aquila.

With binoculars folk were able to easily split some well known double stars including Mizar and Alcor in the handle of the dipper and the Double Double next to brilliant Vega.

The highlight, close to midnight, was viewing the Andromeda galaxy, which was just visible despite the very challenging conditions. A few people had never seen another galaxy before and amazed binoculars could produce such excellent views.

Thanks to everyone who came along, a safe homeward journey and clear skies!  I look forward to returning next year.

Belladrum Boffinarium

Bella-Boffinarium-372x372

Catch me at Belladrum Tartan Heart Festival this week.  On Thursday at 8pm I’ll present a Beginner’s Guide to Stargazing and the Night Sky in the Boffinarium.

Then on Friday and Saturday night from 11pm I’ll take groups out for binocular and naked eye stargazing (weather permitting). Fallback for cloudy skies will be a repeat of Thursday’s stargazing talk and planetarium software guiding.

Practical group sizes for stargazing will be about 25 people so outdoor guiding will be on a fist come first served basis.

ISF Talks – Island Universes

I’ve recently finished delivering two public lectures on Galaxies at this year’s Inverness Science Festival.

The theme of my talks was ‘Island Universes’, telling the tale of when and how we discovered our Milky Way isn’t the only galaxy, and how the teeming multitudes of spiral nebulae, hitherto believed to be collapsing dust clouds, were in fact individual galaxies.

The talk started with some observational astronomy, before discussing the great debate of 1920 between Harlow Shapley and Heber Curtis.  The main unresolved issue here was the distance to the spiral nebulae, particularly Andromeda, which was unknown.  This lead us into pulsating stars and the work of Henrietta Swan Leavitt, who systematically analysed and determined the period luminosity law for cepheid variable stars.

Finally we discussed Edwin Hubble and the ramifications of his observations on the red shift of distance galaxies, and how this has informed our current understanding of the history and future dynamics of the universe.

I’ll let some choice slides do the talking from here on.

Our own galaxy ‘The Milky Way’ is big.  If you tried to travel from our position to the galactic nucleus at the speed of the Voyager spacecraft it would take you over 400 million years.

A 1900s image of the Andromeda nebula.  Back then the consensus was these spirals were large collapsing dust clouds, a bit like the star forming Orion nebula.  The idea that they could be separate galaxies like our Milky Way seemed inconceivable, yet that’s where the evidence eventually lead in the 1920s.

Screenshot 2019-05-13 at 16.05.51.png

Determining the distance to spiral nebulae (as they were known pre 1900) required a new way of determining distance from so-called ‘standard candles’.  Leavitt’s law was invaluable when Hubble turned his attention to Andromeda in 1922.

Hubble discovered the galaxies were all rushing away from us.  However this phenomena is actually a metric expansion of space itself, and therefore has no intrinsic centre.  Some of the most distant galaxies are receding away at faster than the speed of light – again due to the expansion of space itself, which has no speed limit imposed.

There were lots of questions on M87, the giant elliptical galaxy whose black hole was recently imaged by the Event Horizon telescope.

Q&As are always lively after astronomy and space talks, and the younger audience members always surprise me with their amazing knowledge and frank curiosity.  Some choice sample from the two evenings below.  Answers on a postcard please .

1. Is the singularity at the end of a black hole the size of the Planck length?

2. If a giant hole suddenly appeared in the Earth how many Pluto’s could you fit inside it?

3. Do supermassive black holes continue to grow until they devour the host galaxy?
