Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com Episode 507. 1st - Carbon Star V Air best tonight 2nd - Saturn Neptune and Moon congregate in evening sky 4th - Two Shadows on Jupiter IO and Euorpa after 10pm here for us so that's midnight EST. 5th - Full Moon (closest moon of the year) Asteroid Victoria at opposition. Asteroid "12 Victoria" is a large S-type (stony) asteroid in the main asteroid belt, discovered in 1850 by J.R. Hind. It orbits between Mars and Jupiter, recently, a meteor event occurred over Victoria, Australia, in August 2025, which created a sonic boom and was large enough for fragments to potentially have landed on the ground. 5th & 6th - Moon Near Pleiades NGC's 253 & 288 well placed tonight 7th - Cleomedes Sunset Rays visible on Moon 9th - Carbon Star VX And Best tonight 10th - Jupiter 4-degrees S of Moon 11th - asteroid 471 Papagena at opposition 471 Papagena is an asteroid that was discovered by German astronomer Max Wolf on 7 June 1901 12th - N Taurid Meteors ZHR=5 The Northern Taurid meteor shower, active from roughly October 20 to December 10, peaks around November 12. It is known for producing bright, slow-moving fireballs that are easy to spot with the naked eye. The shower is caused by Earth passing through debris from Comet Encke 14th - Zodiacal Light becomes visible this month 17th - Leonid Meteors this morning The Leonid meteor shower is an annual event that peaks around November 17th, when Earth passes through debris left by Comet 55P/Tempel-Tuttle. These fast, bright meteors appear to originate from the constellation Leo, which is how they got their name. Under normal conditions, you might see 10 to 15 meteors per hour, but every 33 year,.... 19th - Carbon star WZ Can best tonight 20th - Gegenshein Visible 68 Leto M=9.9 at opposition. It is a large main belt asteroid that is orbiting the Sun. The asteroid was discovered by German astronomer Robert Luther on April 29, 1861, and is named after Leto, the mother of Apollo and Artemis in Greek mythology. It orbits at a distance of 2.78112 AU over 4.64 years and has an orbital eccentricity of 0.187. The orbital plane is inclined at an angle of 7.97° to the ecliptic.68 Leto is a large main belt asteroid that is orbiting the Sun. The asteroid was discovered by German astronomer Robert Luther on April 29, 1861, and is named after Leto the mother of Apollo and Artemis. It orbits at a distance of 2.78112 AU over 4.64 years. Two Moon shadows on Jupiter Carbon star TX Psc best tonight 21st - Uranus at Opposition 23rd - Mercury and Venus Pair in morning sky 24th - Saturn Ring tilt -0.37 27th - Lunar X Alphonsus Sunrise Ray visible on Moon 28th - Lunar Straight wall visible this evening 29th - Saturn, Neptune and Moon congregate in evening sky 2 bright comets R2 Lemmon and A6 Swan - Concluding Message: Please subscribe and share the show with other stargazers you know and send us show ideas, observations and questions to actualastronomy@gmail.com We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

From October 15, 2025. The Universe is hard enough to figure out without one kind of object dressing up as another, but - just in time for Halloween - researchers have figured out that the Little Red Dot in the early Universe just might be massive black holes surrounded in a costume of glowing red gas. Also in this episode, Hyabusa2's amusingly tiny destination, a white dwarf star eating what may be an icy dwarf planet, and tales from the launch pad.
