First photos from the James Webb Space Telescope show some of the oldest stars.
Globular clusters include some of the oldest stars in modern galaxies like ours, although their ages are unknown
Sparkler is one of millions of galaxies distant behind SMACS 0723, the first publicly released James Webb Space Telescope image.
Lamiya Mowla and her colleagues noticed an extended galaxy with yellow blobs
