Double Helix Issue 80

Cover of 'Double Helix' magazine issue 80, showing a molten sun in space, being orbited by a planet.

In this final issue of Double Helix, we find inspiration in the number 10, in celebration of the magazine's 10th anniversary.

Double Helix just finished ten trips around the Sun! Being our last issue and being exactly ten years old are both reasons to look back on what we’ve done. + Full description

Meet the spacecraft taking a ten-year journey to the Sun. Meanwhile, engineers are making ‘a star on Earth’ with fusion technology. The number 10 inspired us to find out what can happen in 10 nanoseconds versus 10 millennia. Plus, we celebrate 10+ trailblazing scientists.

Get really hands-on with ten by using your fingers to count above 1,000. If those numbers aren’t big enough, get a handle on the huge distances between the Sun and the planets by making a model solar system. And to celebrate 10 years, we give you our ‘best ever’ biscuit recipe.
