  • Event – Staring at the Sky – Astronomy at the UCL Observatory

    By Nicholas J Booth, on 25 September 2015

    The Whirlpool Galaxy lies 30 million light-years away.   It was the first galaxy in which spiral structure was discovered in 1845.

    UCL’s astronomical observatory was inaugurated in 1929, and it has been conducting research and teaching students ever since. On Friday 2nd October the Observatory and UCL Public and Cultural Engagement department will host a pop-up event which will feature staff and research students from the Observatory, and hopefully (if the weather behaves) give visitors the chance to make some solar observations with a specialised telescope.

    Astronomy was originally taught on the main UCL site, using equipment in the two domes in the front quad (built 1905-07) together with one on the roof of the Wilkins Building (destroyed during World War 2). However, the light pollution of central London began to cause issues and a new site was required.  A suburban site in Mill Hill site was chosen, in part because it was far away enough from London that the night sky could be observed without excessive pollution. Since then, London has grown, and the Observatory now sits well inside the M25; however it continues to be a great asset for teaching Physics and Astronomy students.

    The Observatory currently houses five telescopes: in order of when they were acquired, the Fry 8-inch refractor telescope (acquired 1930 but originally built in 1862), the Radcliffe telescope (acquired 1938, built 1901), the Allen 24-inch reflecting telescope (1974/75) and two modern, computer-controlled C14 telescopes (acquired 2006 and 2010).

    The Observatory made news recently when a team of students, being trained by Dr Steve Fossey, spotted a supernova (exploding star) in nearby galaxy Messier 82 (also known as the Cigar Galaxy). Images of the galaxy (with supernova) will be available on the day; they will also form part of an accompanying exhibition in the South Cloisters, of images taken at the Observatory, running from late September.

    The pop-up event will be open (rain or shine) between 11.30am – 4.30pm on Friday 2nd October, in the Wilkins North Observatory (in the front quad on campus).

    The Mullard Space Science Laboratory

    One of the things I enjoy most about my job is that I get to work with many different departments from across UCL. I meet people from a wide range of backgrounds and get to do some pretty interesting stuff with them. And of course being a curator I get to work with collections as well, which is in my opinion the best thing about working in museums.

    In the last few months I have had the good fortune to visit the Mullard Space Science Laboratory (MSSL). A part of UCL that very few people get to see, staffed by people who are extremely passionate about their jobs, and housing a whole new collection of objects that I didn’t know existed.

    The MSSL was opened in 1967, and is the largest university space research group in the UK. Not only that but its early date marks it as one of the earliest such centres in the world, and makes it an important part of the early history of the British Space Programme, now known as the UK Space Agency (yes we really do have one of those). The lab is located near (more…)
