Why Do We Even Need Big Telescopes? (ESOcast 241)
Why do we aim for bigger and bigger telescopes, such as ESO’s Extremely Large Telescope currently under construction in Chile’s Atacama Desert? And how does the effort pay back, not only in terms of astronomical discoveries but also to the whole of s
Peeking at a Distant Moon-Forming Disc (ESOcast Light 240)
Using ALMA, a team of astronomers have unambiguously detected a moon-forming disc around a distant planet for the first time. The planet is a Jupiter-like gas giant, hosted in a system still in the process of being formed. The result promises to shed
Cosmic fireworks reveal newborn stars (ESOcast Light 239)
A team of astronomers have released colourful new observations of nearby galaxies obtained with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) as part of the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) project
Who Turned off the Lights on Betelgeuse? (ESOcast 238 Light)
When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community was puzzled. A team of astronomers have now published new research done with ESO's Very Large Telescope an
Testbed Asteroid Hunter Sees First Light (ESOcast 237 Light)
Part of the world-wide effort to scan and identify potentially dangerous asteroids and other near-Earth objects, asteroid hunter Test-Bed Telescope 2 (TBT2), a European Space Agency telescope hosted at ESO’s La Silla Observatory in Chile, has now sta
ESOcast 236 Light: First interstellar comet may be the most pristine ever found
New observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) indicate that the rogue comet 2I/Borisov, which is only the second and most recently detected interstellar visitor to our Solar System, is one of the most pris
ESOcast 235 Light: Astronomers Image Magnetic Fields at Black Hole's Edge
The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has today revealed a new view of the massive object at the centre of the Messier 87 galaxy: how it looks in polarised light. This is the first time as
ESOcast 234 Light: Most distant quasar with powerful radio jets discovered
With the help of ESO’s Very Large Telescope, astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a “radio-loud” quasar — a bright object with powerful jets emitting at radio wavelen
ESOcast 233 Light: Six-Exoplanet System with Rhythmic Movement Challenges Theories of How Planets Form
Using a combination of telescopes, including the Very Large Telescope of the European Southern Observatory (ESO's VLT), astronomers have revealed a system consisting of six exoplanets, five of which are locked in a rare rhythm around their central st
