welcome

There’s a celebratory mood this issue as we mark the diamond anniversary of The Sky at Night. First broadcast on 24 April 1957, it’s a programme that for 60 years has brought us close to the cutting edge of scientific exploration month in, month out. We start our celebrations on page 31, where we hear from current producer Michael Lachmann, then on page 32, presenter Chris Lintott shares some of the biggest stories to have been covered on the programme, while Pete Lawrence charts the developments in telescope technology during that time. On page 40, we have a tribute to the man who started it all, Patrick Moore, written by friend and fellow astronomer Brian May. Here’s to another 60 years! Elsewhere this issue, we’re taking a close look at the…

follow that star!

The Orion Nebula is the closest active star-forming region to Earth. For this reason, astronomers continually keep telescopes aimed in its direction in order to observe the many processes that occur here: old stars dying in violent explosions, new stars being born and radiation carving shapes in the surrounding nebula clouds. This image is zoomed in on the Kleinmann-Low Nebula, part of the Orion Nebula Complex. It’s actually a mosaic created by several Hubble observations made in near-infrared and optical light. The many red dots are stars seen by Hubble in infrared that would otherwise be obscured by opaque pockets of dust and gas. Astronomers have been scouring this region for free-floating exoplanets that race through space, free from the influence of a host star. But while looking for these runaway planets,…

the star cluster with the wrong stars

Young stars have been found hiding in a stellar cluster once thought to have been populated exclusively with old stars, in a discovery that has caused astronomers to rethink one of the cornerstones of astronomical science, the process of how stars evolve. The discovery was made by researchers studying star clusters at infrared wavelengths in the Large Magellanic Cloud (LMC), one of the Milky Way’s satellite galaxies. They found that of the thousands of stellar candidates studied, 15 were much younger than the others in their cluster. “Our models of stellar evolution are based on the assumption that stars within star clusters formed from the same material at roughly the same time,” says Bi-Qing For, an astronomer from the International Centre for Radio Astronomy Research in Perth. The consistency among cluster stars has…

The Universe isn’t as simple as we’d like, and astronomers get few breaks in our quest to understand what’s happening within it. Unable to carry out experiments (except using the simulated universes that live within supercomputers), the critical skill for any astrophysicist is finding smart ways to interpret observations. What this means is we look for ways to make things simpler. For example, it’s great if you can assume that all the stars in a star cluster formed at the same time. That means we know we’re seeing a set of stars which are all the same age, making clusters an excellent laboratory for watching stars form – the closest we get to a controlled experiment. That’s why this result is so interesting; only a small number of stars have formed recently,…
