New Eyes on the Sun

Patricia Daukantas

Three solar observatories—two in space, one on Earth—are using advanced optics to study our closest star in greater detail than ever before.

Wine Glass Caustics
Wine Glass Caustics

The optical phenomenon called caustics is observed in this image under room light illumination, which results in the light interacting with the curved surface of the wine glass to form a colored ring in the center of the glass containing Finnish Glögi. The image was captured in Joensuu, Finland with a smartphone camera with EXIF data and post-processed with a camera filter. EXIF data: ISO:500, S:1/33 s, EV:0, F: 1.8, focal length: 140 mm (equivalent to 35mm focal length film).
