Nucleosynthesis: Book release by Prof Claude Doom

Selfie with the auteur, Prof. Claude Doom

Yesterday I could pick up my ordered new book "Nucleosynthese, het onstaan van de elementen in het heelal". The auteur, Prof. Claude Doom did sign the book and was willing to make a selfie. 

The book was created as a result of a series of 5 leasons on Nucleosynthesis which I online attended in 2020-2021 at the astronomyclub, Beisbroek in Brugge.  (see my certificate)

Lecture by Huib Jan van Langevelde : Zooming Into Black Hole Sagitarius A*

Selfie with Prof. Huib Jan van Langevelde

Dutch astronomer Huib Jan van Langevelde is working at the JIVE in Dwingeloo, professor of galactic radio astronomy at Leiden University and director of the Event Horizon Telescope (EHT) consortium. The EHT is a project in which some 350 scientists from 18 countries work together. The EHT bundles the large ALMA telescope in Chile with other (sub)millimetre telescopes and published the first image of a black hole in 2019 and the black hole Sagitarius A* in our Milky Way in 2022. 

At the JVS/VVS weekend of Oct 1,2022, Prof. Huib Jan van Langevelde gave a lecture on zooming into a black hole using milimeter telescopes.

Some really good video's:
