In early 2021, just after the Perseverance Rover landed on Mars, a purported image of the Martian night sky went viral. In that image, above the sleek metal of a Mars rover, the clearly defined Milky Way cuts from horizon to horizon, crossing a sky filled with so many stars that there is no darkness […]

Authors: Predrag Slijepcevic, Senior Lecturer in Biology, Brunel University London and Nalin Chandra Wickramasinghe, Honorary Professor, University of Buckingham Are we alone in the universe? The famous Seti (Search for Extraterrestrial Intelligence) programme has been trying to answer this question since 1959. American astronomer Carl Sagan, and many others, believed that other human-like civilisations must […]

Jupiter is a huge gaseous giant dressing with contrasted belts and zones and an ancient reddish spot.

The Rosetta mission from the European Space Agency is arguably one of the most successful highlights of 2014. Even though the Philae lander did not have the placid flight we all would like it to have, the team managed to fulfill most of its scientific goals before the batteries get exhausted and there is still […]
How far are the stars we see every night? This was possibly one of the first questions early astronomers asked themselves and it is still among the most fundamental problems for present day astrophysics. In some sense, astronomers do build the Universe as the observing methods allow them to place neighboring stars, distant galaxies or […]
