Comet C/2025 R2 (SWAN) is a long-period comet first spotted on September 11, 2025 by amateur astronomer Vladimir Bezugly in publicly available images from the SWAN (Solar Wind Anisotropies) instrument aboard the SOHO spacecraft, before receiving an official designation from the IAU. It was already unusually bright (magnitude ~7.3) with a well-developed tail at the time of discovery, just hours from perihelion. Its orbit suggests a period of roughly 22,500 years, meaning this is likely its only visit to the inner solar system in recorded history.

Comet C/2025 A6 (Lemmon) is a long-period comet discovered on January 3, 2025 by David C. Fuls as part of the Mount Lemmon Survey at the University of Arizona's Steward Observatory, when it appeared as a faint asteroidal object roughly 4.5 AU from the Sun before follow-up observations revealed cometary activity. It brightened substantially as it approached the Sun, becoming visible to the naked eye around its closest approach to Earth on October 21, 2025. Its orbit suggests it won't return to the inner solar system for a very long time, if ever.

Messier 81, also known as Bode's Galaxy, is a classic grand-design spiral galaxy in Ursa Major lying about 12 million light-years away, with a disk spanning roughly 90,000 light-years. It forms a gravitationally bound pair with the nearby starburst galaxy M82, the two separated by only about 130,000-150,000 light-years, close enough that their mutual gravitational interaction has visibly disturbed M82's structure and triggered intense star formation there. M81's own spiral arms are well-defined and rich in star-forming regions, wound tightly around a bright, dust-free central bulge. Because the pair fits comfortably within a single wide-field frame, M81 and M82 are frequently imaged together, offering a striking visual contrast between M81's calm, orderly spiral and M82's turbulent, edge-on starburst disk.
