Astronomers have recently gained a captivating glimpse into the potential cradles of new planets. Cutting-edge ground-based telescopes in Chile have provided stunning views of protoplanetary disks surrounding young stars in three neighboring regions. The European Southern Observatory (ESO) unveiled these groundbreaking images, showcasing a diverse assortment of nurseries.
Among the observed regions, astronomers directed their attention to Orion, a gas-rich cloud positioned 1,600 light-years away from Earth. Remarkably, they discovered that smaller disks were more prevalent around stars in group formations of two or more. Additionally, the disks exhibited irregularities, implying the growth of massive exoplanets within them. These exoplanets possibly induce warping and misalignment in their celestial cocoons.
Another star-forming location, Taurus, situated approximately 600 light-years away, provided further revelations. Telescopes captured images portraying both the scattered light from young stars’ dust and the glowing dust itself, illuminating their surroundings.
These extraordinary findings enable astronomers to discern patterns and trends. Christian Ginski, a lecturer at the University of Galway in Ireland and the lead author of one of the three published papers, expressed the significance of transitioning from scrutinizing individual star systems to comprehending entire star-forming regions.
The observations, conducted by scientists from more than ten countries, utilized the powerful tools of ESO’s Very Large Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile’s Atacama Desert.
With over 5,000 known exoplanets, astronomers acknowledge the astonishing diversity found in these alien worlds and their ecosystems, differing greatly from our own Solar System. To comprehend the origins of this diversity, scientists focus their attention on the dust- and gas-rich disks enveloping young stars, the very cradles of planet formation.
Undoubtedly, exploring these planetary birthplaces requires specialized instruments. ESO’s Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument, mounted on the VLT, played a crucial role in producing sharp and detailed images of these significant locations. By employing adaptive optics, SPHERE corrects for interference from Earth’s atmosphere, enabling the imaging of faint discs around stars with masses as low as half that of the Sun.
The variety and intricate beauty observed in these celestial nurseries have left the scientific team awestruck. The dramatic spiral arms seen in some of the observed disks are believed to be influenced by orbiting planets. Per-Gunnar Valegård, a doctoral student at the University of Amsterdam and the lead author of the Orion study, captured the poetic essence of these processes that usher in the formation of planets and, potentially, life: “It is almost poetic that the processes that mark the start of the journey towards forming planets and ultimately life in our own Solar System should be so beautiful.”
