The Atacama Large Millimeter/submillimeter Array (ALMA) is a state-of-the-art telescope to study light from some of the coldest objects in the Universe.

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 with our host Doctor J, a.k.a. Dr. Joe Liske. The ESOcast HD is presented in High Definition.

In ESOcast 149 we hear from some of ESO’s current students about their experience at ESO, and they offer their advice to those considering following in their footsteps.

In the star-forming region Lupus 3, in the constellation of Scorpius (The Scorpion), dazzlingly hot stars are born from collapsing masses of gas and dust.

A new national facility at ESO’s La Silla Observatory has successfully made its first observations. The ExTrA telescopes will search for and study Earth-sized planets orbiting nearby red dwarf stars. ExTrA’s novel design allows for much improved sensitivity compared to previous searches. Astronomers now have a powerful new tool to help in the search for potentially habitable worlds.

Astronomers using ESO’s MUSE instrument on the Very Large Telescope in Chile have discovered a star in the cluster NGC 3201 that is behaving very strangely. It appears to be orbiting an invisible black hole with about four times the mass of the Sun — the first such inactive stellar-mass black hole found in a globular cluster.

The first hexagonal segments for the main mirror of ESO’s Extremely Large Telescope (ELT) have been successfully cast by the German company SCHOTT at their facility in Mainz. These segments will form parts of the ELT’s 39-metre main mirror, which will have 798 segments in total when completed. The ELT will be the largest optical telescope in the world when it sees first light in 2024.

Astronomers using ESO’s Very Large Telescope have for the first time directly observed granulation patterns on the surface of a star outside the Solar System — the ageing red giant π1 Gruis.

This ESOcast Light explores how and why engineers are undertaking wind tunnel tests for ESO’s Extremely Large Telescope.

The OmegaCAM imager on ESO’s VLT Survey Telescope at the Paranal Observatory in Chile has captured a glittering view of the stellar nursery called Sharpless 29. Many astronomical phenomena can be seen in the giant image, including cosmic dust and gas clouds that reflect, absorb, and re-emit the light of hot young stars within the nebula.
