An international team of astronomers using the HAWK-I camera attached to the European Southern Observatory’s Very Large Telescope captured this stunning deep infrared view of the Orion Nebula in 2016 showing an abundance of brown dwarfs and planetary-mass objects. The famous nebula stretches 24 light years across and even though it is about 1,350 light years from Earth it is easily visible to the unaided eye as the somewhat fuzzy “star” in the middle of Orion’s sword. Amelia Bayo, co-author of a paper discussing the HAWK-I view said “understanding how many low-mass objects are found in the Orion Nebula is very important to constrain current theories of star formation. We now realise that the way these very low-mass objects form depends on their environment.”
The artistic outburst of an extremely young star, in the earliest phase of formation, is captured in this spectacular image from the NASA/ESA Hubble Space Telescope. The colourful wisps, found in the lower left of the image, are painted onto the sky by a young star cocooned in the partially illuminated cloud of obscuring dust seen to the upper right.
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.
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.
