The best naked-eye and
binocular sights to observe
throughout 2021

As you read through this issue of
All About Space,
you’ll notice
there’s something a little different. This month, we’ve launched
our very own augmented reality (AR) experience, enhancing your
journey through the universe with the aid of your smartphone.
This issue – and for many editions to come – scan the QR
code and you’ll be able to play videos, see spacecraft in three
dimensions as they leap off the page and much more. Turn to the contents page for a
quick tutorial and look out for the ‘AR’ stamps as you move through the magazine.
This month we’ve got plenty to keep you entertained throughout lockdown – whether
you’re keeping out of the harsh wintry weather or have been gifted with crystal-clear
skies for a spot of observing. Our cover feature assesses the chances of a space war – and
whether planet Earth is really ready for a cosmic battle – before we head to nearby star
system Proxima Centauri to investigate what could have caused a signal picked up by the
Parkes Radio Telescope in Australia. We also uncover the truth about the different kinds
of dark matter, the chances of being killed by a falling meteorite and provide details of
the very best sights to observe without a telescope.
See you next time. I hope you enjoy your enhanced
version of
All About Space
as much as we loved
making it. Stay safe!
