Summary: ESOcast is a video podcast series dedicated to bringing you the latest news and research from ESO – Astronomy made on planet Earth. Here we explore the Universe's ultimate frontier with our host Doctor J, a.k.a. Dr. Joe Liske.
ESOcast 109 Light: Full steam ahead with ELT primary mirror (4K UHD)
The first stone ceremony for ESO’s Extremely Large Telescope has taken place at the Paranal Observatory in northern Chile, in the presence of the President of Chile.
ESOcast 107 Light: Secondary Mirror of ELT Successfully Cast
The "4 Laser Guide Star Facility" was installed at the VLT and are the most powerful laser guide stars ever used in astronomy. Creating multiple artificial stars gives a better understanding of atmospheric conditions, which leads to a better image.
ESOcast 105 Light: Starstruck by the Small Magellanic Cloud (4K UHD)
ESO has teamed up with Evans & Sutherland and the International Planetarium Society and others from the community to make a standard. We call it Data2Dome, in order to get the latest information into the domes.
The stunning new ALMA Residencia building has just been handed over.
Stellar explosions are most often associated with supernovae, the spectacular deaths of stars. But new ALMA observations of the Orion Nebula complex provide insights into explosions at the other end of the stellar life cycle, star birth. This ESOcast Light takes a quick look at the important facts.
New observations from ESO's Very Large Telescope have revealed stars forming in the huge outflows in galaxies, which are driven by central supermassive black holes. This ESOcast Light takes a quick look at the important facts.
New observations from ESO's Very Large Telescope have revealed that the outer parts of massive disc galaxies 10 billion years ago were rotating less quickly than the spiral galaxies, like the Milky Way, that we see today. This ESOcast Light summarises the important points of this discovery and the significance of dark matter, and how it is distributed.
ALMA observations have revealed that a very distant galaxy, seen when the Universe was just 4% of its current age, was rich in cosmic dust. This ESOcast Light quickly looks at what this means and why it is important.
A new image from ESO’s Very Large Telescope gives a very detailed view of the edge-on galaxy NGC 1055. This ESOcast Light takes a quick look at this image and explains what it shows.
This ESOcast Light presents five amazing facts about the 7 Earth-sized planets found in the nearby TRAPPIST-1 system, from their rocky composition to their potential to harbour water.
Astronomers have found a system of seven Earth-sized planets just 40 light-years away. Using ground and space telescopes, including ESO’s Very Large Telescope, the planets were all detected as they passed in front of their parent star, the ultracool dwarf star known as TRAPPIST-1.
It’s hard to comprehend the sheer size of objects in space , but let’s give it a try!
