Celestial cat meets cosmic lobster

3 February 2017 Stephen Clark

Astronomers have for a long time studied the glowing, cosmic clouds of gas and dust catalogued as NGC 6334 and NGC 6357, this gigantic new image from ESO’s Very Large Telescope Survey Telescope being only the most recent one.

First signs of weird quantum property of empty space?

30 November 2016 Astronomy Now

By studying the polarisation of light emitted from an extraordinarily dense and strongly magnetised neutron star using ESO’s Very Large Telescope, astronomers may have found the first observational indications of a strange quantum effect known as vacuum birefringence, first predicted in the 1930s.

‘Pillars of destruction’ in the Carina Nebula

2 November 2016 Astronomy Now

Spectacular new observations of vast pillar-like structures within the Carina Nebula have been made using the MUSE instrument on ESO’s Very Large Telescope. The different pillars analysed by an international team seem to be pillars of destruction — in contrast to the name of the iconic Pillars of Creation in the Eagle Nebula, which are of similar nature.

Unexpected gaseous haloes detected around distant quasars

26 October 2016 Astronomy Now

An international team of astronomers has discovered glowing gas clouds surrounding distant quasars. The new survey of these active galaxies indicates that haloes around quasars are far more common than expected. The properties of the haloes in this surprising find are also in striking disagreement with currently accepted theories of galaxy formation in the early universe.

Starving black hole returns brilliant galaxy to the shadows

19 September 2016 Astronomy Now

The mystery of a rare change in the behaviour of a supermassive black hole at the centre of a distant galaxy has been solved by an international team of astronomers using ESO’s Very Large Telescope along with the NASA/ESA Hubble Space Telescope and NASA’s Chandra X-ray Observatory. It seems that the black hole has fallen on hard times and is no longer being fed enough fuel to make its surroundings shine.

Rare fossil relic of early Milky Way discovered

7 September 2016 Astronomy Now

A fossilised remnant of the early Milky Way harbouring stars of hugely different ages has been revealed by an international team of astronomers. Terzan 5 resembles a globular cluster, but is unlike any other cluster known. It contains stars remarkably similar to the most ancient stars in the Milky Way and bridges the gap in understanding between our galaxy’s past and its present.
