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.

The Leonids

9512431565_4537aea986_b

The radiant of the Leonids is in the constellation Leo, but you don’t need to look in that directions to see shooting stars.

The annual Leonids meteor shower is due to peak over the weekend between 17 and 18th November 2018.  Although the waxing gibbous Moon will diminish conditions somewhat it will still be more than worthwhile heading out somewhere dark to observe them.  Over the peak as many as 10-15 meteors per hour may be visible.  Occasionally meteor showers will erupt into storms, as was the case with the Leonids in November 1833, when 100,000 meteors per hour rained down over an entire evening!

The shower is caused by the Earth colliding with the debris left behind by comet Temple-Tuttle, a short period comet with a period of 33 years.  Temple-Tuttle is due to swing past the Sun again in May 2031, when it will once again deposit fine dust trails behind it, seeding future generations of meteor showers.

The tail of a Comet always points away from the Sun.  Debris from the Comet’s tail produce most meteor showers, as the Earth intersects the fine dust trails in its annual orbit around the Sun.

Observing the Leonids

You don’t need any special equipment to view a meteor shower, in fact binoculars or telescopes will just narrow your field of view. Grab a deck chair or a warm blanket, prepare a hot drink, wrap up warm and lay out under the darkest conditions you can find. It’s an excellent activity to do alone or if you have children they’ll love an excuse to get outside for some after dark play.

Put away any lights or bright mobile phones and simply look up and wait. Remember it takes up to 30 minutes for your eyes to fully dark adapt and any exposure to bright lights will start the process all over again. If you need a light red touches are best for preserving you night vision.

For optimal viewing, head out after the Moon sets, or in the darkness of the pre dawn sky.

Approximate Moon set times at Highland latitudes this weekend:

Friday night 12.30am
Saturday night 1.30am

You can still see meteors with the moon up but generally only the brightest ones. Early morning viewing will be optimal as Leo (the radiant) is high in the sky then.

Good luck and clear skies!
