Marcelo Borges Fernandes from ON communicated the OCEANS project to PhD students and postdocs during the XII SimFAST meeting (Simpósio de Física e Astronomia da Universidade do Vale do Paraíba - Physics and Astronomy Symposium of the University of Vale do Paraíba) that took place in the period 28 - 30 May 2025. Marcelo presented an online talk with title "The Mysteries of Massive Stars".

OCEANS team members from ASU participated in the organization and implementation of the outreach activity Open Days that took place Friday, 16 and Saturday, 17 May 2025 on the gounds of the Ondřejov Observatory with a manifold program for children and adults.

The main activities, in which OCEANS members were involved, took place at and around the Perek 2-m telescope, which is an important telescope used by ASU members for their scientific activities in the frame of OCEANS. With this telescope, optical spectroscopic data of massive stars and binaries are collected and analyzed. The OCEANS project was presented on a poster (in czech language).

Moreover, we had prepared flyers in both czech and english language that we distributed to interested visitors, while kids had good times with painting and building rockets, posing as an astronaut, and having their face decorated with space ships, rockets, planets, and aliens.

In addition, numerous films on various astronomical topics were presented and visitors had the opportunity to view the telescope up close. Our team members were available to answer any questions.

Around 2,000 visitors took advantage of this opportunity and attended this public event. We are already looking forward to the next public event, where we hope to reach and inspire even more people interested in our science and astronomical topics in general.

The posters and flyers can be accessed through our Information page.

Five Researchers from ASU participated at the DPG Spring Meeting of the Matter and Cosmos Section (SMuK) that took place in the period 31 March - 4 April 2025 at the University of Göttingen, Germany. In the frame of this conference, the Extraterrestrial Physics Division organized splinter meetings on solar and heliospheric physics, near-Earth space, planets and small bodies, exoplanets and astrobiology, and astrophysics.

Within the latter, that was organized and chaired by Michaela Kraus, they presented 3 contributed talks (Olga Maryeva - "Newly discovered nebulae around Galactic B-type stars and their origins", Dieter Nickeler - "On the existence and (non-)uniqueness of null points of flows and magnetic fields as prerequisites for the existence of astropauses", Kuljeet Singh Saddal - "3D Resistive MHD Perspectives on the Localized Dynamics at the Apex of an Astropause") and 4 posters (Michaela Kraus - "OCEANS - Overcoming challenges in the evolution and nature of massive stars", "Near-infrared characterization of evolved massive stars in M31 and M33", Olga Maryeva - "Revealing the pulsation-induced mass loss of blue supergiants and its interplay with the interstellar medium", Julieta Sanchez Arias - "Stochastic high frequencies in massive stars").

This conference was attended by about 1,700 researchers from various fields, which offered the opportunity to present OCEANS, recent progress and research results, and to discuss with astrophysicists and physicists from different disciplines.
