The division maintains several instruments, databases, and other resources useful for local and international astronomers:

• The 90 cm Bengt Westerlund Telescope, on top of Ångström Laboratory
• The Astronomy and Space physics division library
• The MARCS database of stellar atmosphere models (model-atmosphere tables, continuous-opacity data files, and sampled energy fluxes)
• The VALD database of atomic line parameters of astrophysical interest
• A public ftp server for exchanging astronomical data
• The Astronomy Wiki for collecting useful information
