UKZN will host the 5th National Research Foundation (NRF) Astronomy Advisory Council meeting on the 26th of June 2015 at the Westville campus. The Council is responsible for providing scientific advice to the NRF Astronomy sub-Agency, which is headed by the Deputy CEO for Astronomy, Prof Nithaya Chetty.
Ground breaking research, international academic collaborations and facilities such as the Karoo Array Telescope (MeerKAT) and the Southern African Large Telescope (SALT) have driven the growth of astronomy in South Africa. The Council, which is composed of leading researchers will guide the implementation of South Africa’s Astronomy strategy which aims to further grow this field of science and thereby benefit both the local and international community. In addition, it will also encourage the production of important new research in various areas of astronomy and strive to increase the number of local astronomers.
We invite the South African astronomical community to participate in the Astronomy Town Meeting 2015 which will be hosted by UKZN at the Protea Hotel, Umhlanga, Durban, 26 – 28 June 2015. Read More
ACRU member Dr. Cynthia Chiang, returned in January from a two month visit to Antarctica where she participated in an experiment called SPIDER that studied the earliest moments of our universe’s creation.
SPIDER consisted of six telescopes that were launched into the stratosphere with a giant helium-filled balloon, which swelled to roughly the size of Durban’s Kings Park stadium at its 35-km cruising altitude. From this lofty height, SPIDER observed the faint, leftover heat from the Big Bang: this afterglow, known as the cosmic microwave background (CMB), contains valuable clues that will help unravel the mysteries of our universe’s explosive beginnings. The experiment was built by an international collaboration that includes Princeton University, the University of Toronto, Case Western Reserve University, the California Institute of Technology and the Jet Propulsion Laboratory, and the University of British Columbia.

Dr. Chiang joined the SPIDER collaboration in 2009 as a postdoctoral research fellow at Princeton University. She was responsible for testing and operating SPIDER’s cryostat, a large vessel that houses the six telescopes and cools them to -270 degrees Celsius using 1000 litres of liquid helium. SPIDER was launched on January 1, 2015 and spent 17 days in flight.
“I was absolutely thrilled to finally see SPIDER in the air. It’s taken many long years of hard work and dedication from people across the globe, and collaborating with such a talented and cohesive team has truly been a blessing for me. We’re all eager to see the data in full when the telescopes have been retrieved, and we look forward to facing the new challenges of sifting through our observations. We at ACRU will be actively involved in the analysis, and we plan to continue collaborating on SPIDER for its second flight” said Dr. Chiang.
Public Talks in October and November
In the next two months, we will be holding two fascinating Public Talks:
Deep Cinematography of the Whole Sky with the Large Synoptic Survey Telescope (LSST)
On the 8th of October 2014, Dr Abhijit Saha from the National Optical Astronomy Observatory in Arizona will deliver a Public Talk on the Large Synoptic Survey Telescope (LSST). The Large Synoptic Survey Telescope is projected to come online in 2019 and begin a survey of the whole sky visible from Cerro Pachon in Chile. Read More
SKA, MeerKAT and more – radio astronomy in Africa
On the 5th of November 2014, Justin Jonas will speak on radio astronomy in Africa. Justin Jonas is the Associate Director: Science & Engineering, South African SKA Project Office, National Research Foundation (a joint appointment with Rhodes University). This talk will provide an overview of the strategies and initiatives that have led to Africa becoming a major “destination” for radio astronomy, and an update on the progress towards the completion of the MeerKAT and the design of the SKA Telescope.
