Infrared image of the Beta Pictoris planetary system. The image shows the star's dusty debris disk and the giant planet Beta Pictoris b at two different positions in its orbit (October 2003 & November 2009), captured by the European Southern Observatory telescopes. The planet's orbit is roughly the size of Saturn's orbit around our Sun.

Cross correlation plots showing a clear detection of water and carbon monoxide in the atmosphere of Beta Pictoris b. The signal appears as a clear yellow dot in a sea of dark purple and black.
A paper on the exoplanet #BetaPictoris b led by Leiden student Rico Landman showcasing CRIRES+ on the VLT - arxiv.org/abs/2311.13527 precise measurements of CO and water, P_rot=8.7hr and a RV precision of 0.3km/s. Hmm, 0.3km/s precision.... now there's an interesting thought! 🔭🪐
