Astronomers have observed two black holes in nearby galaxies devouring their companion stars at an extremely high rate, and spitting out matter at a quarter the speed of light.
In 1995, in Geneva, PhD student Didier Queloz discovered a planet orbiting another sun – something that astronomers had predicted, but never found. Today he continues his terra hunting for extreme worlds and Earth twins in Cambridge.
A new method of measuring the distances between stars enables astronomers to climb the ‘cosmic ladder’ and understand the processes at work in the outer reaches of the galaxy.
The Gaia satellite has discovered a unique binary system where one star is ‘eating’ the other, but neither star has any hydrogen, the most common element in the Universe. The system could be an important tool for understanding how binary stars might explode at the end of their lives.
A team of astronomers have created the first standardised set of measurement guidelines for analysing and cataloguing stars.
Latest research has uncovered a massive clump of carbon monoxide in a young solar system. The gas is the result of near constant collisions of icy comets – suggesting vast swarms of tightly packed comets in thrall to the gravitational pull of an as-yet-unseen exoplanet.
Gaia-ESO data show Milky Way may have formed ‘inside-out’, and provide new insight into Galactic evolution20 Jan 2014
Research on first data release from Gaia-ESO project suggests the Milky Way formed by expanding out from the centre, and reveals new insights into the way our Galaxy was assembled.
