Astronomers have discovered a series of unusual globular star clusters with masses far exceeding what would be expected under the standard model for the celestial structures. The clusters are located in the giant elliptical galaxy Centaurus A, and seem to hint at an enigmatic dark presence that cannot yet be accounted for.

Astronomers have used the ESO's Very Large Telescope (VLT) in conjunction with the NASA/ESA Hubble Space Telescope to reveal the secrets of how star formation shuts down in distant galaxies, just three billion years after the Big Bang. Focusing on huge, quiescent elliptical galaxies known as spheroids, the findings are expected to improve our understanding of the evolution of the Universe. Read More
The ESO has turned the Spectro-Polarimetric High-contrast Exoplanet Research instrument (SPHERE) towards an unusual double star with the expectation of finding an orbiting brown dwarf. However, the observations didn’t quite go according to plan, with the instrument – which is the latest addition to the Very Large Telescope (VLT) – coming up short. The findings have led to an ongoing re-examination of the cause of the binary stars’ unusual behaviour. Read More
A team of ESO astronomers have discovered two stars at the heart of a planetary nebula that are destined to collide some 700 million years from now, igniting a vast supernova explosion. The findings support theories concerning Type Ia supernovae and the irregular shape of some nebulae. Read More
Astronomers using the ESO’s Very Large Telescope (VLT) in Chile have discovered an unexpected alignment of the spinning axes of supermassive black holes located billions of light-years apart. As if that discovery wasn’t fascinating enough in itself, the team then delved a little deeper, finding that the quasars aren’t just linked to each other, but are also aligned with the large-scale structure of the Universe itself.

Using an instrument mounted on the European Southern Observatory's (ESO's) Very Large Telescope (VLT), scientists have been able to shed light on some of the mysteries surrounding stardust by observing the event and aftermath of a supernova. The observation was undertaken in an attempt to answer a number of questions regarding stardust, chief of which being where and how the grains are formed and grow. Another oddity that the team hoped to resolve was just how these tiny, fragile particles manage to survive the inhospitable environment that prevails following a supernova. Read More
A new scientific instrument for detecting and observing remote exoplanets has been successfully installed on Unit 3 of the ESO's Very Large Telescope (VLT). The Spectro-Polarimetric High-contrast Exoplanet REsearch instrument, or SPHERE, recently returned its first set of images and is promised to revolutionize the exploration and study of these distant celestial bodies.

Magnetars are extremely dense and highly magnetic neutron stars that can form when a star goes supernova. They are extremely rare, and until now, it has been difficult to determine how and why they form. However, thanks to new data collected by the Very Large Telescope (VLT) at the ESO’s Paranal Observatory in Chile, astronomers believe they have finally solved the great mystery. Read More
The European Space Observatory's Very Large Telescope (VLT) has spotted a massive yellow star with a diameter of more than 1,300 times the size of the Sun. The star is also a part of a binary system, with a companion star orbiting so close that it is actually in physical contact with the giant. Read More
