welcome

There’s one thing about the aurora that I find especially fortuitous, it’s that our planet’s protective magnetic field transforms deadly radiation from the Sun into an awe-inspiring spectacle. I’ll be keeping this in mind as we get into aurora season this month – the time of year when slightly warmer temperatures, improving weather and still-dark nights make a search for the spectacle more rewarding. To help you get the most out of this time, turn to our feature on page 28, where Tom Kerss explains the processes behind the Northern Lights and how to see them yourself. Another event of note in the night sky this month is the opposition of minor planet Vesta, the brightest of the asteroids. In ‘The Sky Guide’ from page 43, you’ll find all the details…

magnetic mayhem

HUBBLE SPACE TELESCOPE/SOFIA, 14 JANUARY 2021 From its vantage point aboard a Boeing 747SP, 12km above Earth, NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has revealed the hidden mayhem unfolding in the Whirlpool Galaxy, M51. By mapping the magnetic fields that course through its graceful, curling arms SOFIA’S far-infrared instrument, the High-Resolution Airborne Wideband Camera (HAWC+), uncovers a far more chaotic picture than suggested by previous radio observations. The camera – which detects the polarised light emitted as spinning dust grains align in the presence of magnetic fields – shows that while the fields are relatively orderly’near the massive black hole at the galaxy’s core, things get far more turbulent in the outer spiral arms, where the streamlines weave back and forth across the structure. Hundreds of red-pink areas of star formation, gas…
