An international collaboration, with the participation of the Instituto de Astrofísica de Canarias (IAC), determines with an unprecedented level of precision the mass, age and rotation profile of the core of a massive pulsating star. Known as HD 192575, it has been observed by the NASA space telescope TESS continuously for more than a year. The results shed new light on how such stars are internally structured and how they evolve until their death, when they explode as supernovae and form neutron stars and black holes. The scientific team has also used observations made with the Mercator

The XXXIV Canary Islands Winter School of Astrophysics closed last Thursday, November 16, with the visit to the facilities of the Obervatorio del Teide. For two weeks, 54 graduate students from 15 countries attended the IACTEC building to learn about the latest developments in the field of galaxy evolution and the Local Group. Currently, astrophysics field is receiving a big amount of data available for research due to the Gaia Mission and several spectroscopic surveys from Earth in which the IAC has a large participation. The organization highlights the great enthusiasm, the good atmosphere

Yesterday, 30 October 2023, from the telescope itself at the Roque de los Muchachos Observatory on the island of La Palma, the WEAVE instrument, a powerful state-of-the-art multi-fibre spectrograph, was publicly unveiled. The inauguration ceremony brought to La Palma the leaders of the science funding agencies from the partner countries of the Isaac Newton Group of Telescopes (ING), as well as a strong representation from the 500 members of the science teams and the organisations involved in the design and construction of WEAVE, making it the largest ever gathering of people inside the dome
