Some 290 million years ago, a star much like the sun wandered too close to the central black hole of its galaxy. Intense tides tore the star apart, which produced an eruption of optical, ultraviolet and X-ray light that first reached Earth in 2014.
Comet 41P/Tuttle–Giacobini–Kresák orbits the Sun every 5.4 years and will pass through perihelion (its closest point to the Sun) on 12 April 2017. Motoring through Ursa Major at close to 2°/day during the remainder of March, this fascinating comet with a history of dramatic surges in brightness, passes close to Messier 97 and 108 on the UK night of 22 March.
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.
On 5 March 1979, Voyager 1 made its closest approach to Jupiter, passing at a distance of about 349,000 kilometres (217,000 miles) from the planet’s centre. It captured this close-up view of the swirling clouds around Jupiter’s Great Red Spot in February as it approached the gas giant.
