Perturbations of artificial satellites in orbit described by team with Polish researchers

What happens to artificial satellites orbiting the Earth, and how does General Relativity affect orbits and movement of satellites? Scientists from the Wroclaw University of Environmental and Life Sciences and ESA explain.

    New radio map of the Universe reveals thousands of star-forming galaxies

    An international team of astronomers including Polish researchers has published the most accurate map of the universe to date in the low radio frequency range. The new sky survey enables scientists to study tens of thousands of galaxies, all the way to the far reaches of the Universe. The LOFAR telescope (a trans-European network of radio antennas, three of which are located in Poland) was used for observation.

    Scientists image magnetic fields at the edge of supermassive black hole

    Space researchers analysing the properties of a supermassive black hole have managed to both measure its polarization and imaged its magnetic field.

  • The most detailed ultra-long radio wave sky map ever made with the LOFAR instrument. Each of the 25,000 dots corresponds to a supermassive black hole that swallows cosmic matter from the galaxy in which it is located. The map comes from the LOFAR LBA Sky Survey (LoLSS), an ongoing survey of the entire northern sky using the low-frequency portion of the LOFAR interferometer.

    Warsaw researchers develop detailed optical reddening maps of Magellanic Clouds

    The most accurate maps ever created of the interstellar reddening in the Magellanic Clouds have been presented by astronomers from the Astronomical Observatory of the University of Warsaw working in the OGLE sky survey project. The clouds which are seen as a 'laboratory' for galaxy studies, and the maps have now been hailed as an ‘excellent tool’ for further cosmological research.

Polish scientists reinterpret petroglyphs of Toro Muerto

The geometric patterns, lines and zigzags that accompany the images of dancers (danzantes) carved in the rocks of the Peruvian Toro Muerto are not snakes or lightning bolts, but a record of songs - suggest Polish scientists who analyse rock art from 2,000 years ago.
