Comet 3I/ATLAS captured by the JANUS camera
Comet 3I/ATLAS as seen through the red and violet filters of JUICE's JANUS camera. In the red filter (shown here in orange), the bright centre of the coma appears more compact and two tails are visible – one pointing straight downwards and another, fainter tail extending downwards to the left. In the violet filter (shown here in blue), the coma appears larger but fainter, with only one tail clearly visible. These differences arise because different gas and dust particles emit or reflect light at different wavelengths.
