Information about important observations with telescopes at the ESO observatories at La Silla and Paranal are regularly published via ESO Press Releases. They may relate to all kinds of different astronomical objects, from comets to variable stars, and from supernovae to distant gamma-raybursters.

Information about these observations, observations with other telescopes, and major astronomical events is available on IAU Circulars, as communicated by observers and published by the IAU Central Bureau for Astronomical Telegrams (CBAT). Please note that new Circulars are only placed on the Web after they have been distributed by email to the regular subscribers.
