Star Stories Astronomy Outreach Update

The Star Stories astronomy programme at Abriachan Forest is going from strength to strength, with tickets selling out far in advance of each event.  Since the last update we’ve hosted two stargazing evenings, involving guest speakers Dr Anthony Luke (UHI) and Professor Martin Hendry (Glasgow University).

The November event was a Leonids special, held near the peak of the annual meteor shower on Nov 16th, with the promise of perhaps observing some early atmosphere skipping Leonids.

Dr Anthony Luke presented a fascinating set of lectures on the chemistry of meteors and stars in the forest classroom, touching on the incredible pressure and heat generated within stellar forges that produce all the elements we see around us.

Meanwhile, I led the stargazing component outside with perfectly clear skies allowing us to take in the brightest stars, and views of the gibbous Moon in video telescope.  The lunar observing was particularly captivating, and we discussed the formation of the lunar maria and highlands, and the Theia Moon formation hypothesis.

Clelland was also in action over the forest campfire making wooden star models for the younger participants.  There were no dramatic meteor sightings to match October’s spectacle but the event certainly whetted everyone’s appetite.

 

Then on December 5th, Glasgow University’s Professor Martin Hendry (of gravitational wave fame) joined us under dark skies for a Wednesday night special.

Martin is a hard working and inspirational advocate of all things astronomy and space.  Prior to me collecting him at his hotel he had already delivered a packed day of outreach to Inverness schools and hadn’t had a bite to eat since lunch.  Despite this he was incredibly grateful for the cold pizza I offered him on our drive out to Abriachan, and this meagre fare fuelled him sufficiently to deliver two fantastic talks on dark matter and gravitational waves in the forest classroom.  His talk highlighted some of the latest discoveries and simulations from the LIGO (Laser Interferometer Gravitational-Wave Observatory) team.

The following day he was off on the train again to speak to more schools in the far north.

We were also blessed with lots of clear breaks on the 5th, so I once again led the observing component outdoors, this time taking groups further back into the darker areas above the classroom where the Milky Way was ablaze, and fainter fuzzies like the Andromeda galaxy leapt out at us in our binocular and naked eye views.  Amongst many things we discussed the evolution of hot massive stars like Betelgeuse and the Kepler exoplanet survey, which has been scanning vast numbers of star systems close to Cygnus and Vega, cataloging extrasolar planets.

Prior to packing away the binoculars I snapped some pictures of the starry skies close to the forest classroom (attached).

Both evenings have garnered fantastic feedback and we’re looking forward to the next events, listed below.

As always a big thanks to learning coordinator Suzann Barr, Ronnie, Clelland and the rest of the Abriachan team who help make these events so welcoming and successful.  We’re also grateful to grant funding from the STFC, allowing us to invest in observing equipment, free transport and to extend the scope of this year’s programme.

Meteoric Start to New Star Stories

The new Star Stories astronomy programme for the 2018/2019 season got off to a great start up at Abriachan Forest Trust last Friday, with plenty of clear breaks in skies for Milky Way observing and binocular stargazing. This was despite very unsettled weather predicted by the MET office as storm Callum blew in from the west.

This first event was in collaboration with the Highland Archaeology Festival, and pitched on a loose Neolithic stargazing theme which I had worked into a backup talk in the event of cloudy skies.  As it happened we had enough clear conditions to stargaze all evening and the talk was parked for another occasion.

Due to the healthy turnout we split the night into two streams, with one group joining Abriachan’s Clelland for Celtic tales around an open fire, while the other group joined me under darkness for a laser pointer and binocular tour of visible constellations.  We then swapped over at half time.

Both stargazing groups saw plenty of open sky despite fast moving cloud, and we were able to field test the new hand held binoculars funded by our STFC grant.  The Milky Way and summer triangle were on fine display in the south with bright lanes of glowing star fields high overhead.  We also saw most of the northern circumpolar constellations, including Ursa Major, and discussed Polaris at some length before sighting the Pleiades in the East and the rich clusters within Perseus and Cassiopeia.

But the most dramatic event was gifted to the first group of stargazers, when a spectacular burning meteor soared overhead towards the north, briefly lighting up the whole sky.  A subsequent discussion on social media prompted another observer in Lairg – Chris Cogan – to post a picture of a very bright meteor he also saw streaking north and lighting up an entire hillside.

This generated a lively discussion and some investigation into how far away two observers can be situated and still see the same bright meteor.  It turns out pretty far!

Due to the high altitude meteors burn up in the atmosphere, about 40 – 60 miles overhead, it’s very possible for two observers hundreds of miles apart to see the same meteor.  The only requirement is they lie along the same approximate vector as the burning space rock.  In this specific case, Abriachan and Lairg are both in a rough line travelling north.  The time recorded on Chris’s picture also checks out with our observing time at Abriachan.  So, all told, reasonably convincing evidence we witnessed the same fireball, seventy miles apart.

Overall feedback on the night has been great so far and I’m already looking forward to the Leonids Special in November, when we will be joined by guest speaker Dr Anthony Luke of UHI, talking about the chemistry of stars and meteors.

Clear skies!
