Some of these would be high school students who attended as members of the SWAPA (Students With A Passion for Astronomy) scheme. This scheme, instigated by Professor John Hearnshaw three Lauren May Year 13, Upper Hutt College, Hutt Valley years ago, invites students from around Aotearoa to submit a My name is Lauren. I go to Upper 300-word essay stating why they have a passion for astronomy Hutt College, and I’m 17 years old. and why they would like to attend the RASNZ conference. Attending the RASNZ’s annual I sent out email invitations to nearly 500 high schools and conference in Dunedin this year was a received 39 excellent entries. Of these, ten were chosen by great opportunity. It opened my eyes John Hearnshaw and myself as winners. These ten SWAPA to the possibilities within astronomy, winners were provided free registration for the conference, free and showed me that I don’t have to be entry to the Saturday night banquet and entry into the Otago one of the top scientists in the world to Museum planetarium show; making a total prize package of make a signifi cant contribution.

Not only are they Society of New Zealand (2017). women involved with a male-dominated topic, but they were also very interesting to listen to. Jennie’s incredible opening Aaron Rumpler Kaikorai Valley HS Dunedin to the conference made me realise that while I do need to start Aayushi Verma Christchurch GHS Christchurch planning my future, nothing is set in stone, my list of options is infi nite. The amazing achievements she has had within her Benjamin Lowe Mairehau HS Christchurch astronomical career are really inspiring and she is someone Ella Williamson Christchurch GHS Christchurch who I aspire to be like. Maria’s engaging, compelling, and Jack Zidich Christchurch BHS Christchurch well-presented talk about space law also made me aware of the Laura Li Palmerston North GHS Palmerston North endless possibilities of astronomy-related jobs there are in the Lauren May Upper Hutt College Hutt Valley world. It had never occurred to me that space law would be something that we need to worry about. At the moment, I’m Rhiannah O’Carroll Epsom GGS Auckland really interested in astrophysics. I like looking at some of the Rian Lee Rongotai College Wellington amazing things in the universe but what I enjoy most is fi nding Simon Vincent Motueka HS Motueka out how and why these things happen.
