First light achieved for next-generation planet-hunter

6 December 2017 Astronomy Now

A new planet-seeking instrument installed on the European Southern Observatory’s Very Large Telescope in Chile has made its first observations, beginning a search for exoplanets with unprecedented precision by looking at the minuscule changes in the light of their host stars.

Best ever image of another star’s surface and atmosphere

26 August 2017 Astronomy Now

Using ESO’s Very Large Telescope Interferometer astronomers have constructed the most detailed image ever of a star — the red supergiant star Antares. They have also made the first map of the velocities of material in the atmosphere of a star other than the Sun, revealing unexpected turbulence in Antares’s huge extended atmosphere.

Supermassive black holes feed on cosmic jellyfish

26 August 2017 Astronomy Now

Observations of “Jellyfish galaxies” with ESO’s Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly.

A tale of three stellar cities

28 July 2017 Astronomy Now

Using new observations from ESO’s VLT Survey Telescope, astronomers have discovered three different populations of young stars within the Orion Nebula Cluster. This unexpected discovery adds very valuable new insights for the understanding of how such clusters form.

Dazzling spiral with an active heart

5 July 2017 Astronomy Now

ESO’s Very Large Telescope has captured a magnificent face-on view of the barred spiral galaxy Messier 77. The image does justice to the galaxy’s beauty, showcasing its glittering arms criss-crossed with dust lanes — but it fails to betray Messier 77’s turbulent nature.

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.
