This week the Sun was hitting its lowest level of solar activity since 2011 as it gradually marches toward solar minimum. See a near spotless Sun revolve in this video from the Solar Dynamic Observatory.
Observers in the UK will find Venus almost directly below the three-day-old Moon low in the south-southwest in deep twilight an hour after sunset on 3 December. The pair will fit in the same field of view of most 8x and 7x binoculars, but a deep-sky treat lies in store for telescope users.
Steve Ringwood appraises the Orion Funscope Astro Dazzle, an eye-catching 4½-inch (114-mm) f/4.4 Newtonian reflector on a tabletop Dobsonian mount designed for beginners. The pre-assembled instrument possesses an inherent simplicity that will not challenge, with an aperture that brings a wealth of astronomy’s best to the viewer, he says.
Saturn’s icy 246-mile-wide moon Mimas (near lower left) appears tiny by comparison to the planet’s rings, but scientists think the all of the small, icy particles spread over a vast area that comprise the rings are no more than a few times as massive as Mimas. The view was obtained by NASA’s Cassini spacecraft at a distance of approximately 564,000 miles from Saturn.
