As an island nation, the UK has almost 17,820km of mainland coastline (according to the Ordnance Survey), which rises to 31,370km when you include its hundreds of islands. When you consider its surface area that’s pretty high, and in fact the UK’s is the 12th longest coastline globally. Our seashore is also a region that has a special appeal to stargazers and astro imagers for many reasons, chief among them being big open views that extend unhindered low to the horizon. In this month’s issue, on page 28 Will Gater is your guide to observing from coastal settings, revealing expert tips on how to observe from public areas responsibly, and the objects that are brought out at their best by a sea view. Whatever your observing location, spring is a great time…

a star is born again (briefly)

HUBBLE SPACE TELESCOPE & PAN-STARRS, 15 MARCH 2021 We can’t blame William Herschel, who first coined the term in the 1780s, but ‘planetary nebula’ is a confusing misnomer. They have nothing to do with planets, but as he had recently also discovered Uranus (which he initially called a comet and a ‘nebulous star’), it’s understandable that Herschel conflated these hazy, disc-like objects with gas giant planets. Planetary nebulae, like the Crab and the Dumbbell, are in fact the death throes of a star which, having exhausted the nuclear fuel at its core, collapses. Its shrugged-off outer layers create a diffuse gas shell, lit from within by a newly formed white dwarf. Abell 78, however, is unusual. Found 5,000 lightyears away in Cygnus, it’s a rare ‘born-again’ planetary nebula. While it has a hydrogen-poor…
