That’s proper, it nonetheless to this present day stays one of many 88 trendy constellations.
This specific statement was a part of the commissioning marketing campaign for Webb’s Close to-InfraRed Imager and Slitless Spectrograph (NIRISS). In addition to performing science in its personal proper, NIRISS helps parallel observations with Webb’s Close to-InfraRed Digicam (NIRCam),” stated the European House Company.
