Lecture, Weds 7th Febuary, 7.30 p.m. “Exploring the end of the Dark Ages” -Dr Stephen Wilkins, (Univ of Sussex)

February 3, 2018 iaaadmin Leave a comment

In the early Universe the only source of light was that left over from the big bang. As the Universe expanded this light was shifted out of visible wavelengths and the Universe entered the (cosmological) dark ages. The dark ages were brought to an end by the formation of the first stars and super-mass black holes a few hundred million years later. As these first stars died in supernova explosions they likely enriched their surroundings with the heavy elements, ultimately allowing the formation of rocky terrestrial planets and even life.

Thanks to the finite speed of light, as we look further away we see the Universe as it appeared in the past. Using the Hubble Space Telescope we have now identified galaxies present only a few hundred million years after the big bang, though have not yet found examples of the first stars and galaxies to form. This final gap will hopefully be filled by the upcoming James Webb Space Telescope, due for launch in mid-2019.

Doors open about 7.15pm. There is free parking available on the campus in the evenings. Admission Free, including light refreshments. We are located in the Bell Theatre, Department of Mathematics and Physics, QUB – details here……

Lecture – 17th Feb – Prof Andy Shearer (NUIG) – “What we don’t know (Dark Energy and Dark Matter)”

February 14, 2016 iaaadmin Leave a comment

We know a lot about the universe but what makes astronomy a continuously fascinating subject is what we don’t know. This includes 96% of the energy of the universe which is in the form of either dark matter or dark energy. Apart from these major considerations there are many other aspects of the universe we don’t understand including : Where do the highest energy cosmic rays come from? Is there life elsewhere in the universe? What are neutron stars made of?

This talk will address these issues but will concentrate upon the dark universe and the current and future attempts to understand both dark matter and dark energy. In the next decade a number of both terrestrial and space borne instruments will try and solve this question.

DIRECTIONS TO DUNSINK OBSERVATORY

Dunsink Observatory is on Dunsink Lane (New Dunsink Lane), Castleknock. The Observatory is at 53 deg 23' 14.3"N, 6 deg 20' 19.0" W, with the entrance off Dunsink Lane at 53 deg 23' 16.6"N; 6 deg 20' 14" W. But Dunsink Lane has been blocked on the city side, and the observatory is now only accessible from New River Road, leading to New Dunsink Lane, off the Navan Road, near the junction of the N3 and the M50 – the Castleknock junction, J 6.

Since the M50 upgrade this has become a complex junction.

1. FROM M50, from Dublin airport direction.

If approaching via the M50 from the Dublin airport direction, exit onto the offslip at J 6, but you MUST then get into the right lane at the offslip, or you'll be way off course! So when you approach that junction, move onto the offslip lane to the left, but then stay on the right hand lane of the offslip. Do NOT keep on going round to your left via the left hand lane on the offslip, which will take you on to Castleknock village!

This right hand of the two offslip lanes will bring you round in a loop directly on to New River Road. Go straight on for 2 km, past Elmgreen Golf course, until you see the road blocked ahead of you: the entrance to the observatory is on the right just before the block.

2. From M50 coming from the Toll side, or inbound on M3/N3.

If coming along the M50 from the South, or the M3 coming in fron Navan direction , exit at Junction 6, the Castleknock roundabout (junction with N3), and follow signs for City Centre via the N3. At the first set of lights just on the city side of that major junction, turn left into New River Road / New Dunsink Lane, then go on straight until you can’t go any further.

3. Coming from City Centre via Navan Road:

If coming from the city centre along the N3 Navan Road, go almost as far as the major N3/M50 junction, and turn right at the lights just before this junction, into New River Road / New Dunsink Lane, then go on straight until you can’t go any further.

NB: Ignore any maps or Satnav which direction you along Dunsink Lane from the City side (i.e. the Finglas direction) – the road is blocked from there just before you reach Dunsink!

Lecture – 3rd Feb – Prof Mihalis Mathioudakis: “What we’ll learn from the biggest solar telescope in the world”

February 3, 2016 iaaadmin Leave a comment

The Sun is the most important astronomical object for humankind with solar activity driving space weather and having profound effects on climate and communications.

The Sun also offers an exceptional physics laboratory where we can study in detail the interactions between the plasma and the magnetic field over an enormous range of spatial and temporal scales. It provides a working example where the effects and phenomena that arise from this complex interplay are visible and can be studied continuously at unprecedented detail. Although these phenomena are likely to be much more pronounced in other cosmic objects, the Sun provides a vantage reference point to study the effects of rotation and magnetism when we can only catch glimpses of similar phenomena in other astrophysical sources.

The Daniel K Inoue Solar Telescope, under construction by the US National Solar Observatory, with first light expected in 2019, will be a revolutionary instrument for ground-based solar physics. It will operate in the optical and near-infrared and be the pre-eminent ground-based solar telescope for the foreseeable future. Key advances in its instrumentation over that currently available include ultra-high spatial (25 km on the solar surface) and temporal (millisec) resolution, high resolution imaging spectroscopy and coronal magnetometry.

I will start with a brief introduction to the field followed by some examples of our recent research. I will then provide a introduction to DKIST, highlighting its key instruments and the QUB-led UK contribution to this facility.

See All Five Naked Eye Planets at Once

January 21, 2016 iaaadmin Leave a comment

From 24th January to about 6th February, you have a rare chance to see all five naked eye planets at once in the morning sky.

Full size view here…..http://irishastro.org/5planets160131.JPG

Looking from left to right, or East to West, they will be: Mercury, Venus. Saturn, Mars, Jupiter.

The latter 4 are easy to see, just before the dawn sky brightens. But we have to wait until about 24th Jan to first glimpse elusive little Mercury, which is always the hardest to see:

Mercury will be easiest to see from about 28th Jan to 2nd Feb, but you can start looking from about 24th Jan in case the skies are cloudy later. The group will be joined by the waning crescent Moon from 31st January.

You should start looking from about 45 minutes before sunrise, say about 07.30, and you'll need a good clear view right down to the horizon in the South East.

Venus will be by far the brightest, a brilliant beacon above the SE horizon. Look about a handspan to the left of Venus, and slightly below it, to try to spot Mercury, which will be much fainter, and not easy to find in the twilight glow. Use binoculars to find it at first if you have them.

Once you've found Mercury, go back to Venus, and then follow that line across the sky to find Saturn (quite bright, creamy white), Mars (moderately bright, reddish) and Jupiter, the second brightest, and white). Altogether they will span more than halfway across the sky.

The group will be joined by the waning crescent moon from 1 February onwards, making an even more glorious sight. The Moon will be close to Mars on 1st Feb , and will form a nice triangle above Venus and Mercury on 6th Feb.

And there will also be 2 bright stars in the line-up as well! Lovely blue-white Spica will lie between Mars and Jupiter, and noticeably red Antares will lie below right of Saturn.

A sight not to be missed!

Lecture Weds 20th January, 7.30 p.m. – Dr Heather Cegla (QUB) – “Discovering Alien Worlds”

January 20, 2016 iaaadmin Leave a comment

This talk, by Dr Heather Cegla, of the Astrophysics Research Centre at QUB, will give a brief overview of the first ever confirmation of planets outside our solar system, the two main exoplanet detection methods, some stumbling blocks on the pathway to confirming an extra-solar Earth-analogue (which is her area of expertise), and discuss some prospects for the future and the efforts we’re taking to discover habitable alien worlds.
