Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.
Riccardo Giacconi was an Italian-American Nobel Prize-winning astrophysicist who laid down the foundations of X-ray astronomy. He was a professor at the Johns Hopkins University.
La Trobe University is a public research university based in Melbourne, Victoria, Australia. Its main campus is located in the suburb of Bundoora. The university was established in 1964, becoming the third university in the state of Victoria and the twelfth university in Australia. La Trobe is one of the Australian verdant universities and also part of the Innovative Research Universities group.

Mount Stromlo Observatory located in the west of Canberra, Australia, is part of the Research School of Astronomy and Astrophysics at the Australian National University (ANU). Australia's oldest telescope and several others at the observatory were destroyed by bushfire in 2003.
The Research School of Physics (RSPhys) was established with the creation of the Australian National University (ANU) in 1947. Located at the ANU's main campus in Canberra, the school is one of the four founding research schools in the ANU's Institute of Advanced Studies.
Albert Vinicio Báez was a Mexican-American physicist and the father of singers Joan Baez and Mimi Fariña, and an uncle of John C. Baez. He made important contributions to the early development of X-ray microscopes, X-ray optics, and later X-ray telescopes.
Arthur Bertram Cuthbert Walker Jr. was an African-American solar physicist and a pioneer of EUV/XUV optics. He developed normal incidence multilayer XUV telescopes to photograph the solar corona. Two of his sounding rocket payloads, the Stanford/MSFC Rocket Spectroheliograph Experiment and the Multi-Spectral Solar Telescope Array, recorded the first full-disk, high-resolution images of the Sun in XUV with conventional geometries of normal incidence optics. This technology is used in solar telescopes such as SOHO/EIT and TRACE, and in the fabrication of microchips via ultraviolet photolithography.
An X-ray telescope (XRT) is a telescope that is designed to observe remote objects in the X-ray spectrum. X-rays are absorbed by the Earth's atmosphere, so instruments to detect X-rays must be taken to high altitude by balloons, sounding rockets, and satellites.
Brian Paul Schmidt is an American Australian astrophysicist at the Australian National University's Mount Stromlo Observatory and Research School of Astronomy and Astrophysics. He was the Vice-Chancellor of the Australian National University (ANU) from January 2016 to January 2024. He is known for his research in using supernovae as cosmological probes. He previously held a Federation Fellowship and a Laureate Fellowship from the Australian Research Council, and was elected a Fellow of the Royal Society (FRS) in 2012. Schmidt shared both the 2006 Shaw Prize in Astronomy and the 2011 Nobel Prize in Physics with Saul Perlmutter and Adam Riess for providing evidence that the expansion of the universe is accelerating.
Min Gu is a Chinese-Australian physicist who currently serves as the Executive Chancellor and Professor at the University of Shanghai for Science and Technology. Previously he was Distinguished Professor and Associate Deputy Vice-Chancellor for Research Innovation & Entrepreneurship at RMIT University.
James Roger Prior Angel is a British-American astrophysicist known for his contributions to astronomy and the design and fabrication of large optics for telescopes, solar power and other applications. He developed the spin casting and stressed lap polishing techniques used at the University of Arizona Richard F. Caris Mirror Lab to produce mirrors for some of the largest optical telescopes in the world. He is a Regents' Professor of Astronomy and Optical Sciences at the University of Arizona.
Benjamin John Eggleton,, is Pro Vice Chancellor (Research) at the University of Sydney. He is also Professor in the School of Physics where he leads a research group in integrated photonics, nonlinear optics and smart sensors and serves as co-director of the NSW Smart Sensing Network (NSSN).
Eroia Barone-Nugent is an Australian science educator. Barone-Nugent is experienced with secondary science teaching, science, and education research and she is an education program leader and innovator. She leads the Growing Tall Poppies Science Partnership Program. She is funded by the Australian Government's 'Australian Mathematics and Science Partnership Program' (AMSPP). The goal of her program is to increase the number of students, especially girls, studying science and particularly physics to year 12 and beyond. Barone-Nugent currently holds a part-time academic role at the Australian University, Canberra, CPAS where she is investing in developing curriculum material to support and encourage young children in early primary school to be curious about science and consider science careers. She continues to make practical and meaningful contributions to the pursuit of and equal access for girls in science.
The Growing Tall Poppies Program was started by Eroia Barone-Nugent and Keith Nugent in 2008. 'Tall poppies’ describes people who rise above the norm for achievement. And the purpose of the Growing Tall Poppies (GTP) program is to help young Australians to become these “tall Poppies” in science.
Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a planned joint venture mission between the European Space Agency and the Chinese Academy of Sciences. SMILE will image for the first time the magnetosphere of the Sun in soft X-rays and UV during up to 40 hours per orbit, improving the understanding of the dynamic interaction between the solar wind and Earth's magnetosphere. The prime science questions of the SMILE mission are:
Ken Baldwin is an Australian physicist who is professor of physics at the Australian National University (ANU). He is the deputy director of the Research School of Physics and the director of the ANU Energy Change Institute.
The Space Variable Objects Monitor (SVOM) is a small X-ray telescope satellite developed by China National Space Administration (CNSA), Chinese Academy of Sciences (CAS) and the French Space Agency (CNES), launched on 22 June 2024.
Lobster Eye Imager for Astronomy (LEIA) is a wide-field X-ray imaging space telescope built by Chinese Academy of Sciences (CAS). It was launched on July 27, 2022 onboard of SATech-01 satellite. It is designed for a lifetime of two years.
Lobster-eye optics are a biomimetic design, based on the structure of the eyes of a lobster with an ultra wide field of view, used in X-ray optics. This configuration allows X-ray light to enter from multiple angles, capturing more X-rays from a larger area than other X-ray telescopes. The idea was originally proposed for use in X-ray astronomy by Roger Angel in 1979, with a similar idea presented earlier by W. K. H. Schmidt in 1975. It was first used by NASA on a sub-orbital sounding rocket experiment in 2012. The Lobster Eye Imager for Astronomy, a Chinese technology demonstrator satellite, was launched in 2022. The Chinese Einstein Probe, launched in 2024, is the first major space telescope to use lobster-eye optics. Several other such space telescopes are currently under development or consideration.
