Hidden views of vast stellar nurseries (ESOcast 262 Light)

Using ESO's VISTA telescope, astronomers have created a vast infrared atlas of five nearby stellar nurseries by piecing together more than one million images.



Observing the ashes of the first stars (ESOcast 261 Light)

Using ESO’s Very Large Telescope, astronomers have found the fingerprints left by the explosions of the first stars.

First image of a black hole expelling a powerful jet (ESOcast 260 Light)

With the help of ALMA, astronomers have obtained a new image of the supermassive black hole at the centre of the M87 galaxy.

Witnessing the Birth of a Distant Cluster of Galaxies (ESOcast Light 259)

Using ALMA, astronomers have detected a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy –– the most distant detection of such hot gas yet. This further reveals just how early these structures begin to form.

The Missing Link for Water in the Solar System (ESOcast 258 Light)

Using ALMA, astronomers have detected the chemical signature of gaseous water in the planet-forming disc V883 Orionis. This acts as a timestamp for the water’s formation, allowing us to trace its journey.

Heaviest Element yet Detected in an Exoplanet Atmosphere (ESOcast 257 Light)

Using ESO’s Very Large Telescope, barium has been detected in the atmosphere of two exoplanets.

Hot Gas Bubble Swirling Around our Supermassive Black Hole (ESOcast 256 Light)

Using ALMA, astronomers have found a hot bubble of gas that swirls around Sagittarius A*, the black hole at the centre of our galaxy, at 30% of the speed of light.

'Black Hole Police' Spot Extragalactic Black Hole (ESOcast 255 Light)

The black hole police, a team of astronomers known for debunking black hole discoveries, reported finding a "needle in a haystack". After searching nearly 1000 stars outside our galaxy, they found that one of them has a stellar-mass black hole as a c

What it Takes to Image a Black Hole

What does it take to capture an image of the black hole at the centre of our galaxy? This video explains how the Event Horizon Telescope (EHT) works, and how astronomers managed to create one massive Earth-sized telescope big enough to “see” at the e

Micronovae – a New Kind of Stellar Explosion (ESOcast 254 Light)

Astronomers have discovered a new type of explosion occurring on white dwarf stars in two-star systems. This video summarises the discovery.
