As stars form and black holes throw out energy, the centre of galaxies can have a build up of energy and require these ‘chimneys’ to offer a route to escape

As stars form and black holes throw out energy, the centre of galaxies can have a build up of energy and require these ‘chimneys’ to offer a route to escape
A recent study has tried to identify dark matter at the centre of our galaxy, but it appears neutron stars can account for their observations
This result is the culmination of 26 years of observations made by the Very Large Telescope in Chile
By observing stars near our galaxy’s centre, astronomers have seen hints of Einstein’s theory of relativity
