Welcome to 2015! The year ahead is a busy one for astronomy. Major events and anniversaries to look out for include:

  • January:  Catch comet C/2014 Q2 Lovejoy with binoculars, or with luck by eye!
  • March 13-14:  Sydney City SkyWatchers 120th anniversary event
  • March 20:  total eclipse of the Sun, but only visible from parts of the northern hemisphere
  • Late March-early April:  Dawn spacecraft arrives at dwarf planet and largest asteroid Ceres
  • April 4: total eclipse of the Moon visible from Australia
  • April 24:  25th anniversary of the launch of the Hubble Space Telescope
  • July 14: New Horizons spacecraft passes Pluto – look out for early images from May
  • July 31: A “Blue Moon” for Australia
  • October 9:  An occultation, or “hiding”, of Venus by the Moon
  • November 25:  centenary of the publication of Einstein’s General Relativity – “The Field Equations of Gravitation”

And finally, 2015 marks the 50th anniversary of the first measurements made by the Narrabri Stellar Intensity Interferometer – this measured the diameters of normal stars, established the temperature scale of stars and helped found the field of Quantum Optics…more about the importance of all this as the year rolls on.
