Looking north in the early evening we see Spica, the brightest star in the constellation of Virgo the Maiden, very high in the sky directly in front of us. Don’t confuse Spica with the planets Mars and Saturn, which are to its right or east.
The historic Apollo 8 capsule that circled the Moon in December 1968 is on display in the Henry Crown Space Centre.

M87, which is number 87 on a list of fuzzy objects discovered by the French astronomer Charles Messier, is one of the most interesting galaxies in the sky. Scientists using X-ray and optical observations recently calculated that at its centre there is a supermassive black hole with a mass six billion times that of the Sun.
This month the first visibility of the crescent Moon after the astronomical instant of new Moon is of particular significance in the Islamic calendar. The Moon was new on Sunday at 8:42 am. After sunset this evening the Moon will have moved sufficiently away from the glare of the Sun to be briefly visible as a thin crescent in the western sky.
Apollo 15 was launched towards the Moon on this date in 1971. Two astronauts, David Scott and James Irwin landed four days later next to the spectacular scenery of the Apennine Mountains. In a lunar first they travelled about 28 km in a Lunar Roving Vehicle.
Facing south in the early evening we see the reddish star Antares among the stars of Scorpius to our left or east. In front of us the Southern Cross with its bright stars stands vertically high in the sky while the two pointers are to its left and almost horizontal.
To help you learn about the southern night sky, Sydney Observatory provides an audio guide/podcast, transcript of that audio, and a sky map or chart each month. This month's guide is presented by Melissa Hulbert, Sydney Observatory Astronomy Educator.
Early risers can see Venus each morning before dawn low in the north-east. Those who are not early birds will need to wait until November when Venus will switch to the evening sky. Tomorrow morning a thin crescent Moon is near Venus; it is above and to the right or east of the planet.

The southern galaxy Centaurus A is relatively nearby at a distance of only 12 million light years from us. From a dark place away from city lights, it is easily visible through a small telescope. At its centre there is a massive black hole with a mass 55 million times that of our Sun.
Changes in sunspot group AR12109 plotted on four separate days. Sketch and copyright Harry Roberts ©, all rights reserved The first week of 2014 July saw the Sun’s south-eastern hemisphere ‘peppered’ with large and complex sunspots – some reached (suitably protected) ‘naked-eye’ size!
Each of the gas giants in the outer solar system are circled by rings. The rings of the outermost planet Neptune were first discovered as arcs on this day in 1984. Five years later the Voyager 2 spacecraft imaged five rings as it passed the planet.
Australia’s research astronomers have gathered at Macquarie University for the annual scientific meeting of the Astronomical Society of Australia. They are discussing the latest studies of the origin of the Universe and the formation of galaxies as well the development of new instruments.
This weekend the Central West Astronomical Society holds its annual AstroFest in the NSW country town of Parkes, the home of “The Dish”. During the day on Saturday there are a series of fascinating talks while in the evening the winners of the prestigious David Malin Awards photography competition are to be announced.
