Operating missions in deep space requires sophisticated tracking stations as well as engineering knowhow. A workshop hosted by ESA will highlight the latest developments in the craft of communicating with spacecraft orbiting in our Solar System, hundreds of millions of kilometres from Earth.
Quantum gravity can be considered the “Holy Grail” of modern physics. The understanding of fundamental concepts like space and time that could be obtained with the merging of Einstein’s General Relativity and the principles of quantum mechanics are still far from being captured and unified in a single coherent theory.
New solutions of Einstein’s equations suggest that a rotating black hole causes a “twisting” in the light that passes alongside, generating vorticity in the photons. This phenomenon, linked to the hidden degrees of freedom of the electromagnetic field, would show the rotational motion of black holes and would therefore help solve contemporary astrophysical questions related to super massive black holes on the inside of galaxies and active galactic nuclei.
The European Week of Astronomy and Space Science (EWASS) will take place from 20 to 23 April in Hatfield, UK.

The UK's Particle Physics and Astronomy Research Council (PPARC) will hold a press conference on Europe's strategy for space exploration on 10 January in London, UK.
The 62nd General Assembly of the United Nations (UN) has officially proclaimed 2009 the International Year of Astronomy (IYA2009).
The European Space Agency has reported the conclusion of successful trials of the European Geostationary Navigation Overlay Service (EGNOS).
The service was used to guide a helicopter as it approached and touched down at an emergency medical service landing pad in Lausanne, Switzerland.
The chemical composition of stars that host planets has persuaded astronomers that planetary debris falling onto the outer layer of the star produces a detectable effect in a dwarf star.
