Summary: ESOcast is a video podcast series dedicated to bringing you the latest news and research from ESO, the European Southern Observatory. Here we explore the Universe's ultimate frontier.
Astronomers have made the most precise test ever of general relativity outside the Milky Way.
Each year, several outstanding early-career scientists have the opportunity to further develop their independent research programmes at the European Southern Observatory. Fellowships are available both at ESO’s Headquarters in Garching near Munich, Germany, and at ESO’s astronomy centre in Santiago, Chile.
ALMA has uncovered convincing evidence that three young planets are in orbit around the infant star HD 163296. Using a new planet-finding technique, astronomers have identified three discrete disturbances in the young star’s gas-filled disc: the strongest evidence yet that newly formed planets are in orbit there. These are considered the first planets discovered with ALMA.
Astronomers using ALMA and the VLT have discovered that starburst galaxies in both the early and the nearby Universe contain a much higher proportion of massive stars than is found in more peaceful galaxies.
Glowing brightly about 160 000 light-years away, the Tarantula Nebula is the most spectacular feature of the Large Magellanic Cloud, a satellite galaxy to our Milky Way. The VLT Survey Telescope at ESO’s Paranal Observatory in Chile has imaged this region and its rich surroundings in exquisite detail. It reveals a cosmic landscape of star clusters, glowing gas clouds and the scattered remains of supernova explosions. This is the sharpest image ever of this entire field.
Astronomers have used observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and ESO’s Very Large Telescope (VLT) to determine that star formation in the very distant galaxy MACS1149-JD1 started at an unexpectedly early stage, only 250 million years after the Big Bang. This discovery also represents the most distant oxygen ever detected in the Universe and the most distant galaxy ever observed by ALMA or the VLT.

Most supernovae occur at the end of a massive star’s life, whose dramatic and catastrophic destruction is marked by one final explosion.
On 26 April 2018, the ESO Supernova Planetarium & Visitor Centre was officially inaugurated, and its doors will be open to the public from tomorrow 28 April 2018. The centre, located at ESO Headquarters in Garching, Germany provides visitors with an immersive experience of astronomy in general, along with ESO-specific scientific results, projects, and technological breakthroughs. All activities in the ESO Supernova will be free of charge during 2018, and shows and other events can be booked online.
The ALMA and APEX telescopes have peered deep into space — back to the time when the Universe was one tenth of its current age — and witnessed the beginnings of gargantuan cosmic pileups: the impending collisions of young, starburst galaxies. Astronomers thought that these events occurred around three billion years after the Big Bang, so they were surprised when the new observations revealed them happening when the Universe was only half that age! These ancient systems of galaxies are thought to be building the most massive structures in the known Universe: galaxy clusters.
New images from the SPHERE instrument on ESO’s Very Large Telescope are revealing the dusty discs surrounding nearby young stars in greater detail than previously achieved. They show a bizarre variety of shapes, sizes and structures, including the likely effects of planets still in the process of forming.
New images from ESO’s Very Large Telescope in Chile and other telescopes reveal a rich landscape of stars and glowing clouds of gas in one of our closest neighbouring galaxies, the Small Magellanic Cloud.
New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create a stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot and fiery, but in reality are so cold that astronomers must use telescopes like ALMA to observe them.

The new MATISSE instrument on ESO’s Very Large Telescope Interferometer (VLTI) has now successfully made its first observations at the Paranal Observatory in northern Chile. MATISSE is the most powerful interferometric instrument in the world at mid-infrared wavelengths. It will use high-resolution imaging and spectroscopy to probe the regions around young stars where planets are forming as well as the regions around supermassive black holes in the centres of galaxies.
