The researchers from the Astronomical Observatory of the University of Warsaw discovered the classical Cepheid with the longest pulsation period known in our Galaxy. This variable star is called OGLE-GD-CEP-1884, and is likely the most luminous, youngest, and most massive Cepheid known in the Milky Way.

When Galileo pointed his first telescope at the Milky Way in the early 17th century, he noticed it consists of countless stars. Since that time, studying the properties and history of our Galaxy has absorbed many generations of scientists. Writing in Science, Polish astronomers from the UW Astronomical Observatory present a unique three-dimensional map of the Milky Way.

Sun and other stars in the Milky Way emit radiation that can be detected by human eyes. Astronomers, however, know many celestial objects that can radiate their energy in the form of X-rays. An international team of scientists, which includes astronomers from the Astronomical Observatory of UW, reported in the “Nature Astronomy” journal the discovery of a new class of X-ray sources.

Prof. Andrzej Udalski from the University of Warsaw has received the Tycho Brahe Prize 2018 “in recognition of the role as driving force behind OGLE (Optical Gravitational Lensing Experiment)”.

The astronomers from the OGLE team found hints of a population of Earth-mass free-floating planets, ejected from their parent planetary systems and gravitationally unbound to any star.

One of the largest observing program in the history of the Polish astronomy marks its 25 years. From 24th to 28th July the international conference concerning the OGLE project will be held at the UW.

Astronomers from the OGLE project have discovered an unknown class of pulsing variable stars. The discovery has been published in the prestigious “Nature Astronomy” journal.
