Dr. Jerzy Grygorczuk, head of the Space Mechatronics and Robotics Laboratory, led the team responsible for the construction of the MUPUS penetrator. We talk to him about the Rosetta mission, uncertainty, and patience

The energy sector is about more than just the electric power in our wall sockets and keeping our homes warm. It is the foundation on which the economy rests, and also a crucial part of the way we affect the environment. To better protect the natural environment, we need, for instance, to develop active catalysts that can change harmful chemical compounds into neutral, or even useful ones

What’s even more important than our scientific achievements is that the applications of our research and the experiences gained by the companies Ammono and TopGaN are increasingly likely to be widely implemented in the Polish economy – says Prof. Sylwester Porowski

Galaxies are a bit like people, in that each one is different. They come in all shapes, sizes, masses and colors. Some enjoy company, others are solitary. Does this variety of shapes and properties reflect their age? Can we describe galaxies as young or old? And, like in the case of people, does their outward appearance enable us to deduce how long they have been around?

Comets have been amazing and intriguing humanity since time immemorial. For scientists they represent precious time capsules, messengers from the earliest stages of the Solar System’s formation. How long do they live? And does a flyby close to the Sun necessarily spell their demise?

We talk to Dr. Włodzimierz Strupiński about the two-dimensional form of carbon that is taking the world of high technologies by storm, Poland’s role in its development, and the relationship between science and business

In the movie “Gravity,” fragments of an old, disused satellite crash into a space station. The collision results in the formation of a high volume of debris, which in turn damages more satellites, causing the breakdown of GPS and the Internet, putting our planet on the brink of chaos. Although this is merely a science fiction blockbuster, the situation it depicts could easily occur in Earth’s orbit. How can we prevent it from happening?

Quantum theory was discovered in 1925 independently by Werner Heisenberg and Erwin Schrödinger. The discovery was the culmination of 25 years of intensive research. Today, its interpretation remains as controversial as it is inspirational

Not being able to carry out our plans frequently leads to frustration. Can a similar phenomenon occur in physics? It turns out that it can

In the early 21st century, modern ground-based very-high-energy gamma-ray observatories have ushered in a new era of astronomy. The number of known gamma-ray sources increased from the handful detected prior to 2002 to more than 150 a decade later. Using three types of telescopes – small, medium, and large-sized – the CTA array will observe many new objects and phenomena. One of these instruments is being designed by Polish scientists and engineers

Discs: these round, flattened objects have been widely associated with athletics competitions since the Antiquity. Thrown correctly, they spin through the air, and the low friction around them means they can travel a long way. But that’s not why discs are important in contemporary astrophysics – here we are interested in the energy they give off

Machine linguistic tools are now so widespread that we barely notice them. But we don’t like to conform to their whims – rather, we want them to adapt to us, to start to understand what we say or write, be it in English, Polish, or otherwise. This requires effective text analysis methods, and digital tools are becoming increasingly sophisticated in response
