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.
Skywatchers in Western Europe looking in the southern sky at dusk on Thursday, 18 October can see the 9-day-old waxing gibbous Moon close to the upper left of Mars, the pair fitting comfortably in the same field of view of typical binoculars. This is also a good night for spotting some prominent martian features telescopically – seeing permitting!
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.
