welcome

In our interview on page 94 this month with author and astronomer Neil deGrasse Tyson about his new book, there’s a memorable line. “The greatest achievement in all of civilization is the awareness that the Universe is knowable,” he says. I can certainly agree: that we understand so much about the vast reaches of space through the application of scientific principles is indeed a triumph. Yet we should not fall into the trap of hubris: as Colin Stuart explains in his feature this issue, the foundation of this intergalactic knowledge – the ‘ruler’ astronomers use to survey the unimaginable distances of space and time – is shakier than we might realise. Turn to page 30 to discover the impossible stars that may be the broken rung in this ‘cosmic distance ladder’,…

Ezzy Pearson News editor “Yuri Gagarin’s flight was one of the greatest moments in spaceflight, but it’s long been hidden behind a veil of secrecy. It was fascinating to get to the real story”. Ezzy on the first human spaceflight, 60 years ago, page 60 Colin Stuart Astronomy author “I’ve always been in awe of how astronomers can measure distances in space, but this article interested me because it appears things may not be as straightforward as they seem.” Colin explores impossible stars, page 30 Jenny Winder Author and journalist “Media hype over supermoons has always irritated me. I think it elevates the public’s expectations, so I wanted to put the record straight.” Jenny separates supermoon fact from fiction, page 72…

HOPE PROBE, 10 FEBRUARY 2021 Three Mars-bound spacecraft set off within days of each other in February – the Emirates Mars Mission, China’s Tianwen-1 and NASA’s Mars 2020 – but it was the UAE (United Arab Emirates) that first successfully entered the Red Planet’s orbit, returning this moody shot encapsulating the mysteries waiting to be unwrapped by all three. The new kids on the planetary spaceflight block, the Emirates took just six years from initial feasibility studies to sending up their atmospheric probe Hope (Al-Amal), the first step in their ambitious 100-year plan, announced in 2017, to ultimately build a city on Mars. Hot on Hope’s heels was China’s Tianwen-1, which arrived in Martian orbit on the same day that this image was taken, although it will be May before the Chinese attempt…
