Quark and neutron stars: how do we tell them apart?

Quark and neutron stars: how do we tell them apart?

25.09.2020
Matter found in the densest stars in the Universe – initially known as radio pulsars – poses a frustrating problem for astrophysicists. Theoretical projections allow for two possibilities: they are either neutron stars or quark stars (also known as strange stars). To tell these two types apart through observation was previously thought impossible. However, physicists from the Jagiellonian University and Cracow University of Technology have recently discovered new features of quark stars that may help discern them from neutron stars.

Signs of life in Venus' atmosphere?

Signs of life in Venus' atmosphere?

18.09.2020
On 14 September information about the discovery of possible signs of life on Venus hit the news headlines around the world, following the publication of the results of a study by an international research team in the prestigious journal Nature Astronomy. In fact, at the moment the scientists are cautious about making any specific conclusions, as they haven’t found any microorganisms, but a chemical compound known as phosphine. What is significant is that according to our current knowledge, its formation on Venus wouldn’t be possible without biological processes.

JU authorities have announced the arrangements for teaching in the first semester of the academic year 2020/2021. The courses will be run in one of three possible modes, depending on the faculty dean’s choice, based on the current sanitary and epidemiological guidelines as well as health conditions of the academic staff and students.

A whole new level of X-ray imaging

A whole new level of X-ray imaging

10.09.2020
To study microscopic samples, scientists often employ computer tomography, which relies on X-rays and polycapillary optics. However, this can sometimes cause problems: to create a 3D model of an object, one has to rotate it and scan its surface. Two researchers from the JU Institute of Physics and the JU SOLARIS synchrotron, Katarzyna M. Sowa and Prof. Paweł Korecki, aim to facilitate this process by devising an unconventional imaging technique.
