Eight separate records from Chinese, Japanese, and Arabic observers place a new star in Cassiopeia between August 4-6, 1181. It stayed visible for 185 days, long enough for court astronomers to log it during the Genpei War in Japan and the reign of Henry II in England. One of only five Milky Way supernovae people recorded before telescopes existed, that guest star faded and left no obvious wreck for modern catalogs to claim.

CMOUNTIPHONE2 Mounting DSLR Lenses iPhone 13 Mod
Evan Monsma spent a few days in Indianapolis turning a broken iPhone 13 into something he calls CMOUNTIPHONE2, a phone that can take Canon EF lenses meant for a full-size DSLR.

A heavier lens was always going to finish the job, so this round starts with metal.

Jaguar Type 01 Reveal EV
Jaguar stopped building cars at the end of 2025 and spent the quiet months turning a polarizing concept into something a customer can order. On Tuesday in New York the covers came off the Type 01, a four-door grand tourer and the first production car on a platform Jaguar built only for itself. The name is a small piece of branding arithmetic. Type points back at older Jaguars, the zero stands for zero tailpipe emissions, and the one marks the first car of the new run.
