Venue of the 44th International School for Young Astronomers
28 December 2022
International Schools for Young Astronomers 2023 to be held in Mexico and South Africa

Applications are now open for the next two International Schools for Young Astronomers (ISYA). Originally planned for 2020, and postponed because of the COVID-19 pandemic, these two events are now set to go ahead in 2023 in Mexico and South Africa.

ISYA is a long-standing project of the International Astronomical Union (IAU), and is now co-sponsored by the Norwegian Academy of Science and Letters (NASL) through the Office for Young Astronomers (OYA).

The ISYAs are three-week-long international postgraduate schools held in regions where students have fewer opportunities to be directly exposed to the full extent of up-to-date astrophysics. The aim of the schools is to broaden the horizons of students through interactions with experts from around the world, who will give lectures on current topics in astrophysics, both theoretical and observational.

The 43rd school, ISYA2023Mx, will take place in Tonantzintla, Mexico, from 17 July to 4 August 2023 at the Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE). Early-career graduate students from Latin American and Caribbean countries are encouraged to apply. The school will focus on large database exploitation, while maintaining an entry-level general astronomy approach. The deadline for applications is 20 February 2023.

The 44th school, ISYA2023SA, will take place in Cape Town, South Africa, from 19 November to 9 December 2023 at the South African Astronomical Observatory (SAAO). Early-career graduate students from African countries are encouraged to apply. The focus of the school will be observational astronomy. The deadline for applications is 31 March 2023.

The 43rd and 44th schools will each accept about 30 students with full support from the ISYA programme and the host institutions. The scientific programmes of the schools are set out below.

More information

The IAU is the international astronomical organisation that brings together more than 12 000 active professional astronomers from more than 100 countries worldwide. Its mission is to promote and safeguard astronomy in all its aspects, including research, communication, education and development, through international cooperation. The IAU also serves as the internationally recognised authority for assigning designations to celestial bodies and the surface features on them. Founded in 1919, the IAU is the world's largest professional body for astronomers.
