The European Southern Observatory’s “Cosmic Gems” programme is an ongoing initiative to collect astronomical images of educational interest and public outreach, showcasing the institution’s powerful telescopes during periods when they cannot be used for science observations. This composite image, captured by the Very Large Telescope’s FOcal Reducer and low dispersion Spectrograph, or FORS, instrument shows a patch of sky in the Crux, or Southern Cross, constellation, a particularly bright section of the Milky Way packed with stars. The use of filters brings out spectacular blues and reds.
Three teams of astronomers have made use of SPHERE, an advanced exoplanet-hunting instrument on the Very Large Telescope (VLT) at ESO’s Paranal Observatory, in order to shed light on the enigmatic evolution of fledgling planetary systems. The explosion in the number of known exoplanets in recent years has made the study of them one of the most dynamic fields in modern astronomy.
The European Southern Observatory’s HAWK-I infrared instrument on the Very Large Telescope (VLT) in Chile has been used to peer deeper into the heart of Orion Nebula than ever before. The spectacular picture reveals about ten times as many brown dwarfs and isolated planetary-mass objects than were previously known.
