Comet C/2025 R3 (Pan-STARRS) has survived its trip around the Sun and is now heading back outwards, never to return to the solar system.
It will be visible after sunset in May; it will remain low in the sky and will diminish in brightness.
Here are some fascinating images captured by the ESA/NASA Solar and Heliospheric Observatory (SOHO) and its Large Angle and Spectrometric COronagraph (LASCO) C3 instrument as the comet completed perihelion between April 24 and April 26.

Solution (shows first move only)
P.S.
The chess puzzle is published on Sundays, Tuesdays and Thursdays at 6:00 p.m. ET.
It is customary for advanced players to wait till midnight ET before posting the full solution. Before then, they provide some stats about the solution (e.g., the minimum number of distinct checkmate moves), help guide others, and sometimes post hints. But there are no hard-and-fast rules; feel free to post comments as you please.
