The cycle of solar activity responsible for modulation of interstellar neutral gas density and pick-up ions along the Earth’s orbit
Our research

The interstellar gas in the Local Interstellar Cloud (LIC) surrounding the Sun is composed mainly of hydrogen and helium. But it contains also other chemical elements, among which the most abundant are oxygen and neon. The neutral atoms from the LIC flow into the heliosphere, where some of them are ionized and carried away with the solar wind as pick-up ions (PUIs), but some of them reach the Earth's orbit and distances even closer to the Sun. Underway, they are focused by solar gravity and form a characteristic, elongated patterns in density, with a cone of enhanced concentration at the downwind side of the Sun.

The enigma on the nearest galactic neighborhood of the Sun resolved
Our research

The November issue of the prestigious science journal Astrophysical Journal Supplement Series presents results of investigations of interstellar matter in the immediate galactic neighborhood of the Sun, carried out by the Interstellar Boundary Explorer (IBEX) space probe. An important contribution to the findings presented in a series of 14 papers published in a special topical issue of ApJS was brought by a team of scientists from the Laboratory for Solar System Physics and Astrophysics of the Space Research Centre of the Polish Academy of Sciences (Centrum Badań Kosmicznych PAN, CBK PAN), led by Dr. Maciej Bzowski.

Rosetta papers with CBK PAN participation
Our research

The issue of Science magazine, 23 January 2015, features four papers about the investigations made with the Rosetta OSIRIS scientific cameras and VIRTIS instruments. Three are co-authored by CBK PAN researcher, prof. Hans Rickman, who is a lead scientist within the OSIRIS team. The fourth paper refers to the results obtained in the experiment VIRTIS, in which dr. Maria I. Błęcka participates.

IN MEMORIAM
News

in memoriaAndrzej W. Wernik, professor of physics in the Space Research Centre of the Polish Academy of Sciences, emeritus since 2014, died in Warsaw on 24 of April 2015.

For the past couple of decades he was one of the most active, stimulated researcher in the Institute. He studied wave propagation in the ionosphere, wave propagation in stochastically inhomogeneous media, ionospheric physics, ionospheric plasma turbulence, acoustic-gravity waves in the upper atmosphere, and methods of data analysis. He educated two generations of scientists from all over the world teaching in physics, but also was an excellent scholar and a splendid teacher of ethics and human relations.

The Solar Physics Division of the Space Research Centre won PAS-NASU competition!
News

The research work: “Dynamic structure of energetic particles in the near Earth space” won special competition organized by the President of the Polish Academy of Sciences (PAS) and President of the National Academy of Sciences of Ukraine (NASU). This research was performed using meas-urements from Polish X-ray spectrophotometer SphinX and the Ukrainian Satellite Telescope of Electrons and Protons STEP-F. Both SphinX, and STEP-F instruments were operating onboard CORONAS - PHOTON satellite. Awarded also were joint works on development of further scientific experiment for interplanetary spacecraft “Interhelioprobe".
