ESOcast 142 Light: Stellar Nursery Blooms into View (4K UHD) 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.

ESOcast 141 Light: ESPRESSO — the Next Generation Planet Hunter The Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations (ESPRESSO) successfully made its first observations in November 2017. Installed on ESO’s Very Large Telescope (VLT) in Chile, ESPRESSO will search for exoplanets with unprecedented precision by looking at the miniscule changes in the properties of light coming from their host stars.

ESOcast 140 Light: MUSE Dives into the Hubble Ultra Deep Field Astronomers using the MUSE instrument on ESO’s Very Large Telescope in Chile have conducted the deepest spectroscopic survey ever. They focused on the Hubble Ultra Deep Field, measuring distances and properties of 1600 very faint galaxies including 72 galaxies that have never been detected before, even by Hubble itself. This wealth of new information is giving astronomers insight into star formation in the early Universe, and allows them to study the motions and other properties of early galaxies — made possible by MUSE’s unique spectroscopic capabilities.

ESOcast 139: ALMA​ ​and​ ​the​ ​Cold​ ​Interstellar Clouds Your home and the Universe have at least one thing in common: they can be very dusty places! When you get back after a very long vacation, it may happen that the windows in your home are so full of dust that you can’t see through them anymore. Surprisingly, astronomers have a similar problem! Powered by WPeMaticoRead More →
