1. IAA Public Lecture Meeting, Wed 15 February: "Icy Worlds of the Outer Solar System" , by Dr Michele Bannister, QUB
Michele is an expert on these mysterious worlds, from 'ex-planet Pluto', to Eris, Haumea, Sedna, Makemake and Quaor and many others, and the mysterious 'Planet 9'. And what about 'Planet X'? Even the classification indicates the mystery; alternative names include Plutinos, EKBOs, Kuiper Belt Objects, Dwarf Planets, Trans-Neptunian Objects, ETNOs, SDOs, and Cubewanos,
Then we have the giant comets residing in the Edgeworth-Kuiper Belt, and the Oort Cloud: what's their story? Did comets bring water to planet Earth?
These objects are of much more than academic interest, as they contain the pristine original material from which our solar system formed.
Recent discoveries are revealing intricate structure in the populations of tiny icy worlds that orbit far beyond Neptune. Surveys with some of the world's largest telescopes are mapping the depths of this vast region. With the >800 discoveries from the Outer Solar System Origins Survey, we are writing the history of how our Solar System was sculpted into shape by the migration of Neptune and the other giant planets. I'll also discuss the few known extreme orbits in this region, and whether they hint at the elusive presence of a distant giant Planet Nine.
FREE REFRESHMENTS in the form of the usual biccies, tea and coffee.
TIME: 7.30 p.m., Bell Lecture Theatre, Physics Building, QUB.
Free admission, including the light refreshments. Free parking on QUB campus after 5.30 p.m. http://irishastro.org.uk/lectu
2. Major Lecture on the Geology of Mars, Wed 22 February, 6.30 p.m.: "EXPLORING THE RED PLANET - ADVENTURES OF THE CURIOSITY ROVER" by Professor Sanjeev Gupta, Imperial College, London. "Since the first flyby in 1965 Mars has been extensively explored by orbiters, landers and rovers and today we know a great deal about the planet's surface, atmosphere and geological history. This lecture will focus on the results from the most recent NASA Mars Science Laboratory mission - THE 'CURIOSITY' ROVER MISSION. It will also look forward to the upcoming European mission." Professor Gupta is a FIELD GEOLOGIST AND expert on Mars GEOLOGY. He is A SCIENCE TEAM MEMBER AND long term science planner on NASA's Mars Science Laboratory Curiosity rover mission which is currently exploring Gale Crater. He has published extensively both on Martian and terrestrial geology.This Lecture is jointly hosted by the IAA, Belfast Geologists Society, and The Geological Society Northern Ireland Regional Group, as part of N.I. Science Festival . Larmor Lecture Theatre, Physics building, QUB, 6.30 p.m.BOOKING - via the NISF website: nisciencefestival.com.
3. N.I. Science Festival: 16 - 26 February. The NISF is back for a third year! And it's the biggest one yet. . Programme update now at nisciencefestival.com. You can now book for all of these events.
4. Venus, aka 'The Evening Star' still high and bright. Venus is still very prominent in the SW in early evening twilight but is now starting to move in closer to the Sun as we see it as it heads towards inferior conjunction in late March. However, the angle of the ecliptic to the horizon is still increasing for us in these latitudes, and further, Venus is moving gradually further North of the ecliptic as we see it. These factor all combine to keep it well up in the darkening sky, at least for another few weeks. more on what happens after that in later bulletins! It is now just about peak brightness, at mag -4.6, and completely outshines neighbouring, Mars, which lies less than a third of the length of the 'Plough', or 'Big Dipper', away to the upper left. Venus can be seen in daylight if you know just where to look.
Venus's phase is now noticeably decreasing as it moves between Earth and Sun: it's now about 28% similar to a 3 or 4 day old Moon, but that will decrease to only 16% by 1 March.
5. ISS The ISS is now ending the current series of evening passes over Ireland; it will commence a new series of morning passes on 3 March. see www.heavens-above.com for details for your own location. Click on a date and time to get a diagram of each pass across the sky as seen from your location.
6. NEW SHOW AT ARMAGH PLANETARIUM, commenced 4 February: "Journey to a Billion Suns"

12. NSS Art Competition: The National Space Society (NSS) is looking for student artists to create original illustrations for the NSS Roadmap to Space Settlement. Submitted artwork should realistically illustrate one of 2017's two themes: People Living and Working in Space Settlements or Medicine and Medical Manufacturing in Space. By realistic, the organisation means as accurate as possible both in science and engineering terms and as closely as possible to what a real space settlement would look like. The contest is open to all full-time students between the ages of 12 and 25. Deadline for submissions is 16 March 2017 (at 11:59 pm UT). Learn more about the contest here: http://www.nss.org/settlement/
13. Cassini Scientist for a Day Essay Contest
NASA's Jet Propulsion Laboratory in Pasadena, California, has announced the 2016–17 staging of its Cassini Scientist for a Day essay contest. Since the Cassini mission to Saturn will be ending on 15 September 2017, this will most likely be the last essay contest for the Cassini mission, for which students are asked to write an essay of up to 500 words about one of three possible imaging targets that the Cassini spacecraft has observed during the past few years. Winners and their classes are invited to participate in a teleconference with Cassini scientists from NASA's Jet Propulsion Laboratory. The deadline for entries is 24 February 2017.

14. Fly A Rocket: The European Space Agency is looking for students for its new "Fly a Rocket!" programme. ESA's Education Office is looking for twenty students to participate in an online course about rocketry. Following completion of the course, the students will have the opportunity to take part in a full launch campaign at the Andoya Space Center in Northern Norway, and to launch a rocket. The course is aimed at younger university students, and it is accepting applications from education, media, and management students, showing that careers in the space sector do not necessarily require a detailed technical or mathematical background.

ll-braking-at-alpha-centauriT here's one major danger in this concept. The gravitational slingshot to Alpha B, and on to Proxima, depends critically on how closely it flies by Alpha A. And that depends equally critically on the braking effect from the radiation from Alpha A. That radiation can be calculated fairly accurately in advance.However Alpha A and to a lesser extent Alpha B, are sunlike stars. Alpha A is the same spectral type as our Sun, but is slightly larger, and 60% brighter, so its radiation would provide a greater deceleration than our Sun would do. Alpha B is slightly smaller and cooler than our Sun, and is only about half as bright. It's a reasonable assumption that both stars, particularly Alpha A, emit Coronal Mass Ejections (CMEs) just as our Sun does - huge blasts of actual particles, rather than just photons, in random directions, on a fairly frequent but unpredictable basis. If a CME hits a sail of that size, it will not only slow it down much more than required, it might also seriously change the sail's orientation and therefore its steering effect. The effect could be that the slingshot round Alpha A would be affected so much that it would not get anywhere near the required distance to slingshot on from Alpha B to Proximahttp://www.dailymail.co.uk/sci encetech/article-4213586/Plane t-release-daily-50-trillion- pixel-image-Earth.html
Estimating the Solar Nebula's lifetime: https://www.sciencedaily.com/
releases/2017/02/170210131006.. Oops! - The nebula did not have 'weight'; it had mass. Weight is what you have when you measure the gravitational pull of one body on another, i.e.my weight on planet Earth, which is different to the weight I would have on the Moon, although my mass would be the same. The nebula contracted because of its own gravitational pull - it wasn't actually on anything else! htm
