six JWST images showing the disappearance and appearance of transient supernovae

Six space telescope images show 2 different observations (rows) of 3 different galaxies (columns). Rows labeled with observation year. Top: 2022; bottom: 2023. Columns labeled with galaxy’s redshift (z). From left to right: 3.8; 2.845; 0.655. Left column: Galaxy labeled z 3.8 looks small, fuzzy, irregular in shape; orange-brown with blobs of blue and white. 2023 image includes arrow pointing to small pinkish blob that is not present in 2022 image. Middle: Galaxy labeled z 2.845 is fuzzy, irregular in shape; orange-brown with white blobs; appears somewhat larger than galaxy z 3.8. 2023 image includes arrow pointing to pinkish-white blob that is not present in 2022 image. Right: Galaxy labeled z 0.655 appears much larger than other two galaxies. It is fuzzy pinkish-white, and has a distinct spiral shape with bright core and spiral arms marked with bright blueish-white blobs. 2022 image includes arrow pointing to bright white circular blob that is no longer apparent in the 2023 image.
