Sen. Asst. Prof. Yanko Nikolov, PhD from IA with NAO is a lead researcher in an international team Research conducted with the 2-m telescope at NAO Rozhen with lead researcher Sen. Asst. Prof. Yanko Nikolov, PhD, from the Institute of Astronomy with National Astronomical Observatory, tracked the eruption of the symbiotic star RS Oph as a nova on August 8, 2021. Astronomers from Bulgaria, Argentina and the USA have participated in the study. The results have been accepted for publication in the prestigious scientific journal Astronomy & Astrophysics and can be found with open access at: https://arxiv.org/abs/2309.11288. The research will be presented by astronomer Yanko Nikolov to a wide audience at the Varna Science Festival on 29 October. Novae eruptions occur in binary star [...]

The International scientific conference "Space, Ecology, Safety - SES 2023" is taking place from 24 to 26 October 2023 at the “Prof. Marin Drinov” Hall of BAS and at the Space Research and Technologies Institute (SRTI). The Forum, which is being held for the nineteenth time, is organised by SRTI. This year's conference is dedicated to the 35th anniversary of the “Shipka” scientific programme and the space flight of Alexander Alexandrov. More than 50 real scientific experiments were conducted during the flight of the second Bulgarian cosmonaut Alexander Alexandrov, and the results of these experiments are still being studied by scientists, Corr. Memb. Petar Getsov said at the opening of the conference. He recalled that in 2004 the leadership of the Space Research and Technologies [...]

An exhibition of images of cosmic objects taken with the new 1.5-m telescope at the National Astronomical Observatory (NAO) Rozhen was opened at the Bulgarian Academy of Sciences. The telescope operates in semi-automatic mode and can be controlled remotely, said the director of the Institute of Astronomy with NAO Prof. Evgeni Semkov. He introduced the author of the photographs - astronomer Sen. Asst. Prof. Milen Minev, PhD. The exposition includes photographs of the planet Jupiter and of stars, nebulae, galaxies, star clusters and formations of interstellar gas and dust such as the famous "Pillars of Creation" in the Eagle Nebula of the Serpens constellation. The telescope is the first large-scale scientific infrastructure which was built entirely with Bulgarian funding, said the President of BAS Prof. [...]

  International conference on "Stellar variability, stellar multiplicity" with the participation of 50 scientists from 15 European countries within the project "COST Action #18104 MW-GAIA: Revealing the Milky Way with Gaia” takes place at Sofia Tech Park from 6 to 8 June 2023. The Institute of Astronomy with NAO at BAS is hosting the event with representatives of the scientific community from Italy, Spain, France, Greece, Czech Republic, Poland, as well as from the USA and Chile. The satellite of the European Space Agency's (ESA) Gaia mission has been operational since December 2013 and is expected to run until 2025. It performs precision astrometry: measuring the positions, distances and motions of stars with extreme accuracy. The aim of the mission is to create the largest [...]
