The interstellar asteroid ‘Oumuamua likely originated in a binary star system, researchers say. The rocky, cigar-shaped asteroid was discovered last October as it made a high-speed pass through Earth’s solar system.
On Thursday, 22 March observers in the British Isles with clear skies can see the 5½-day-old setting crescent Moon pass in front of first-magnitude star Aldebaran in the constellation of Taurus soon after 11:30pm GMT. Depending on where you live in the UK, you might just see the star reappear again shortly before the pair set.
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.
A newly processed view of the Crab Nebula, combining X-ray emissions, ultraviolet, optical, infrared and radio emissions using five different telescopes, reveals an astonishing level of detail in the evolving supernova blast, a complex tapestry of debris powered by a fast-spinning pulsar, the collapsed remnant of the destroyed star.
