This image shows the dusty disc around the young star HD 135344B. It’s a combination of data taken with two different facilities: the Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument at ESO’s VLT in red, and the Atacama Large Millimeter/submillimeter Array (ALMA) in orange and blue. The original SPHERE and ALMA images were released in 2016 and 2015 respectively and didn’t show evidence for the presence of a planet in this disc, first revealed in 2025.
