Scientists have detected a 'hot spot' orbiting Sagittarius A*, the black hole at the centre of our galaxy. The discovery was made by a team led by two Polish astronomers, who analysed the observations made with the Atacama Large Millimeter/submillimeter Array (ALMA).
Small asteroids are a greater threat to human civilisation than large objects, because they are harder to spot in space. Traces of their impacts can explain how often they strike and what consequences they may have. An international team managed by a Polish researcher found a way to locate such craters.
Pedro Duque, the first Spaniard in space, will be a special guest of the Mars robot competition European Rover Challenge (ERC 2022) in Kielce. Scientific competition and debates on September 9-11 will be accompanied by popular science attractions for visitors and a tasting of 'space dishes'.
