Your first contact with the universe
We've detected the oldest light in the universe from 400 million years after the Big Bang, the ISS gets a ‘flying brain’ companion and life on worlds around other stars is questioned
Combining landscapes and stars with long exposures results in some of the best astrophotography images around. Here, one European Southern Observatory photographer Petr Horálek took this fine star trail shot of the Southern Hemisphere sky over the Paranal Observatory in Chile.
Other than the obvious motion of the stars, there was also the appearance of a shooting star cutting across the circular paths. The stars in this hemisphere all rotate around their ‘North Star’ equivalent, known as Sigma Octantis. However, this star is much fainter and far less noticeable than Polaris.
