NGC 4036 is a lenticular (S0) galaxy, NGC 4041 a spiral. Both belong to the NGC 4036 Group (LGG 266) and lie roughly 60–70 million light-years away. They form a loose pair with a projected separation of only a few hundred thousand light-years.

NetHack remains one of hardest tests for long-horizon reasoning & tool use The model has to manage inventory, identify items, avoid death & plan across hundreds of turns Reaching Gehennom is genuine milestone, most runs die long before endgame Watching LLM navigate is fascinating

Black ink is almost never a pure pigment. Capillary action carries the solvent (water) upward; different dyes travel at different speeds depending on their solubility and affinity for the paper. The result is a clean separation of the colors that make up “black.”

About 2,200 light-years away and roughly 100–150 million years old. The cluster sits in a region of dark clouds and faint reflection nebulosity, giving the field extra texture beyond the stars themselves. A classic wide-field target in the northern Milky Way.

Chalcopyrite (CuFeS₂) is the most important copper ore. Fresh surfaces are brassy yellow, but a thin tarnish layer creates spectacular blues, purples and greens through thin-film interference.
