collage drawing showing high-energy ions from the Sun interacting with the Earth's magnetosphere and attacking the electronics of satellites in orbit around the Earth "A review of Solar Energetic Particles prediction models" - under this title, a publication appeared on ScienceDirect, Elsevier's leading platform for peer-reviewed scientific literature. The international team of authors in the study includes scientists from the Institute of Astronomy with NAO - BAS: Assoc. Prof. Kamen Kozarev, Assoc. Prof. Rositsa Miteva, Sen. Asst. Prof. Momchil Dechev and the PhD student from Egypt Mohamed Nedal. Solar Energetic Particles (SEPs) are streams of protons, electrons, and ions accelerated to high energies in the huge eruptions on the Sun's surface and which spread throughout the solar system, "surfing" on the interplanetary [...]

  Prof. Garo Mardirosian from the Space Research and Technologies Institute (SRTI) of BAS was awarded the "Inventor of the Year - 2023" prize of the Union of Inventors in Bulgaria. He received the prestigious award for 4 inventions in the field of protection from disasters and accidents, two of which were for critical infrastructure: the "Kinematic System for Early Warning of Earthquakes for Critical Infrastructure Facilities" and the " Early Warning about Floods along River Beds near Artificial Lakes Barrages ". The application of the first invention is in anti-seismic protection of critical infrastructure facilities - for example nuclear power plants, dam walls, etc., from the effects of destructive seismic waves. It is based on the difference in velocities between the longitudinal and transverse [...]

  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. [...]
