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.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have found the possible ‘sibling’ of a planet orbiting a distant star. This video summarises the discovery.
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.
Using ESO’s Very Large Telescope, astronomers have found the fingerprints left by the explosions of the first stars.
With the help of ALMA, astronomers have obtained a new image of the supermassive black hole at the centre of the M87 galaxy.
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.
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.
Using ESO’s Very Large Telescope, barium has been detected in the atmosphere of two exoplanets.
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.
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 companion. This short video summarises the discovery.
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 edge of black holes.
Astronomers have discovered a new type of explosion occurring on white dwarf stars in two-star systems. This video summarises the discovery.
How do the ingredients for life end up on planets? The discovery of the largest molecule ever found in a planet-forming disc is providing clues.
One team found a black hole, the other challenged their results. This is the story of how they got together to find out who was right.
Active galactic nuclei (AGNs) are extremely energetic sources powered by supermassive black holes. This short video provides insights into these peculiar objects by showcasing a new discovery on the AGN at the centre of the Messier 77 galaxy.
In this short video, we highlight the discovery of planet Proxima d around the star closest to the Sun.
