Astronomers have discovered evidence of three more gas giant worlds orbiting a star already known to host a ‘hot Jupiter’ in an extremely close orbit. The observations raise new questions about how solar systems form.
Now that the season of mists and mellow fruitfulness is upon us and the bright summer stars and planets are slipping away to the west, why not seek out some of the spectacular double stars of the autumn sky? We show you how to find some celestial gems suitable for small to medium telescopes in the constellations of Aquarius, Aries and Andromeda.
It’s holiday time again and the keen observer is faced with the usual dilemma: how does one carry a telescope small enough to be useful to far-flung dark and exotic skies? Fortunately for globe-trotters concerned about optical size and weight, Telescope Service in Germany has the TSAPO60 — a compact and very versatile photo-visual 60mm f/5.5 ED refractor.
Computer simulations are giving astronomers a detailed view showing how the electric and magnetic fields surrounding fast-spinning pulsars spew out electrons and positrons, accelerating them to near light speed in a complex interplay that dominates the nearby environment.
