Number of fleeting radio bursts triples

Astronomers challenge Barnard’s Star planet claim

Radio flashes tied to galaxies’ spiral arms

Orion purchases Meade

Three missions to head for Venus in the next decade

The Sun in the centre • It was an idea independently conceived by two people, two millennia apart.

DECIPHERING THE MYSTERY OF RW AURIGAE • Professional and amateur astronomers band together to study a strangely behaving young binary star.

How old are Saturn’s moons? • A deceptively simple question has caused planetary scientists to rethink some basic physics.

The Milky Way’s Dark Constellations • Many cultures draw patterns in the sky not with stars but with darkness.

Arecibo’s legacy • The tragic loss of the iconic radio telescope abruptly ended more than half a century of science and inspiration.

Neptune and Pallas pass in the night • The big blue planet and a big asteroid put on a show at opposition.

Four tips for better astrophotos • Your first night-sky shots may not be perfect, but they can teach you a lot.

The comets of spring 2021 • Four small-scope-worthy comets will grace our skies over the next few months.

Stepping stone to the SMC • Visit U Tucanae and the glories beyond.

Hills in the middle • The central peaks in larger lunar craters testify to the power of gravity in the moments after impact.

Saturn gets the blues • Look for this striking seasonal colour change on the ringed planet.

NEW PRODUCT SHOWCASE

Observing the Pegasus I galaxy cluster • Up for a challenge? Try scoping this collection of distant island universes.

Exploring bright and dark nebulae • The Milky Way offers a profusion of nebulae, more often than not intertwined.

CATALOGUES GALORE

Buying binoculars for astronomy • Much of the sage advice of the past has become obsolete following recent changes in the equipment marketplace.

CALCULATING FIELD OF VIEW

7×50 PORRO-PRISM BINOCULARS

10×50 PORRO-PRISM BINOS

Knightware’s Deep Sky Planner 8 • There’s a lot to like about this observation-planning software for Microsoft Windows.

Make your own push-to scope • Install digital setting circles in thin air.

Prize in the skies • Sharing the wonder of astronomy with the public.
