Účelem každoroční mezinárodní konference o optice pro rentgenovou astronomii AXRO (International Workshop on Astronomical X-Ray Optics) jsou přednášky a následné diskuse o technologiích pro astronomická pozorování v rentgenovém oboru spektra. Sympozium, které se konalo 8.-11. prosince 2014 v pražské vile Lanna za účasti 40 odborníků z EU, USA, Ruska, Číny, Saúdské Arábie a Japonska, prokázalo důležitost propojování základního a aplikovaného výzkumu. AXRO 2014 uspořádaly Astronomický ústav AV ČR, České vysoké učení technické v Praze a Ministerstvo dopravy ČR. and Vojtěch Šimon.
A song on the created planets, their size, their distance from the Sun and on their course around the Sun /composed by Jan Tadeáš Plaček in the town of Sadská on 5 December 1823/.
For the first time, scientists have observed ripples in the fabric of space time called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein´s 1915 general theory of relativity and opens an unprecendented new window onto the cosmos. Gravitational waves carry information about their dramatic origins and about the nature of gravity that cannot otherwise be obtained. Physicists have concluded that the detected gravitational waves were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole. This collision of two black holes had been predicted but never observed. The gravitational waves were detected on September 14, 2015 at 09.51 UTC by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. The discovery was made by the LIGO Scientific Collaboration (which includes the GEO Collaboration and the Australian Consortium for Interferometric Gravitational Astronomy) and the Virgo Collaboration using data from the two LIGO detectors. Special prominence is given to this topic in the article by Dr. Vladimír Wagner of the Nuclear Physics Institute of the CAS. and Vladimír Wagner.
