Friday 27th October 2017 - Prof. Jeff Cooke - Gravitational Waves, Cosmic Cataclysm and an Astronomical Gold Rush

Friday 27th October at Emerald Secondary College we are incredibly lucky to have Professor Jeff Cooke from Swinburne University of Technology and the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) coming to do a free public talk for us at Emerald Secondary College about the recent groundbreaking discovery of both gravitational waves and electromagnetic counterpart from a single event, the merging of two neutron stars.

Scientists have detected a cataclysimic star collision using both gravitational waves and light.  The discovery is being hailed as a new dawn for astronomy.  Thousands of astronomers were involved, using more than 70 telescopes around (and above) the world.  The discovery confirms theories about the speed of light, how gold is created and the origins of gamma ray bursts.

IMPORTANT: The event is at Emerald Secondary College, 425 Belgrave-Gembrook Rd, Emerald VIC 3782 and we will be meeting at 7:30pm for an 8pm start!

Friday 18th August 2017 - "Astronomy in the Classic Maya Period: Copan Ruinas, Honduras" - Dr Javier Mejuto

At 7pm Friday 18th August MBO in conjunction with Emerald Secondary College presents a free National Science Week event with guest speaker Dr Javier Mejuto, Professor of Cultural Astronomy at the National Autonomous University in Honduras, on "Astronomy in the Classic Maya Period: Copan Ruinas, Honduras".

Dr Javier Mejuto photo portraitThe Mayan Classic period (250 CE- 900CE) is recognized the height of the arts, architecture and urbanism for the Maya, particularly in terms of astronomical knowledge. Observations of the celestial landscape arise in sculptures, buildings, calendars, numbering, writings and all Mayan cultural expressions. This talk will explore the site known as Copan Ruinas - a crucible of outstanding architecture and symbolic language that shows the role of time and cosmos in the religion, rituals, and social ends of the Maya people.

Come and join us on Friday August 18th from 6.30pm at EPAC, Emerald Secondary College, as Culture, Astronomy, History, Maths and Archaeology combine for this fascinating FREE talk. Doors open at 6:30pm and the talk begins at 7.30pm sharp.  Emerald Secondary College are planning a BBQ to raise funds for their astronomy club beforehand and (weather permitting) MBO will have telescopes on hand for night sky viewing afterwards.



Saturday 24th June 2017 - MBO at Belgrave Lantern Parade

Hello everyone,

Another year has flown by and the Belgrave Lantern Parade fast approaches. We had a great time there last year running telescopes and joining in the parade with our Solar System Lanterns.

This year we are on again and would like to invite you to join us. We need people to carry our lanterns (and you are welcome to bring your own) and we also need some keen people to run the telescopes so that we can show the members of the public the wonders of the night sky and promote our Observatory.

The Parade is on Saturday the 24th of June. It normally starts around 5pm although if you are helping you will need to get there a bit earlier. It does not end too late - usually around 9pm, but there are opportunities to stay later. The cafes around Belgrave will be open, so you may want to come early and stop somewhere for a hot chocolate first. For more info contact Heike at This email address is being protected from spambots. You need JavaScript enabled to view it. or Jacquie at

Parking in particular gets a bit crazy so do ask us for advice. Those of you who were there last year will know how much fun this event is.

This event is great for all ages and we need all ages to help out.
