ALT A close-in image of protoplanetary disc HH 30. Parts of the image are labelled “Jet” (above and below the disc), “Conical Outflow”, “Possible Spiral”, “Dark Lane”, “Disk”, and “Tail”. A scale marker in the bottom-left is labelled “300 au”; this is a little wider than the disc itself, but less wide than the conical outflows above and below the disc.

ALT The Firefly Sparkle is a redshift zs⁢p⁢e⁢c = 8.304 ± 0.001 gravitationally magnified arc lensed by the MACS J1423.8+2404 cluster. Left: Full field with the three objects of interest - Firefly Sparkle (center), Firefly-Best Friend (FF-BF; bottom left), and Firefly-New Best Friend (FF-NBF; bottom right) - shown in boxes and circles. The contours show the lines of lensing magnifications (μ= 15, 20, 30, and 40). Top right: zoom in on the Firefly Sparkle with the clusters labelled. Bottom right: source plane reconstruction of the Firefly Sparkle with the position of neighbor FF-BF shown in red circle.
