Comet 46P/Wirtanen captured on November 15 this year using the remote iTelescope (Siding Springs Observatory, Australia).

The comet 46P/Wirtanen is just 1.2km in size but it should be visible in the night sky ths weekend as it makes a close approach to Earth this year. And don't forget the Geminids metor shower.
A comet-gazing opportunity to close out the year.

A bright comet visible in December provides an excellent viewing opportunity for night sky lovers – even potentially with the naked eye.
A spectacular display.
Expect a spectacular display of 120 or more meteors per hour – some of them brightly coloured.
Without the scientific knowledge we have today, ancient cultures turned to myths and legends to understand celestial objects.
The comet 67P/Churyumov-Gerasimenko, seen up close.
Dust can be instructive. The analysis of those collected around the comet 67P/Churyumov-Gerasimenko provided new information on the history of the solar system.

Your guide to some of the best meteor showers for 2018. Where to look and when in both the northern and southern skies to catch nature's fireworks.
Blink and you’ll miss it – until the next one.
A guide to meteor showers – what to look out for and when.
This comet 67P outburst was caused by a cliff collapse.
Scientists discover a growing fault line in the "neck" region of the duck-shaped comet.
Evidence is mounting that water came from within the Earth not from asteroids or comets.
Patience can be rewarded as with this composite of the 2016 Geminids meteor shower, seen over Mt Teide volcano on the Canary Islands, off Spain.
2017 is looking to be a spectacular year for meteor showers. So here's what to look out for in both the northern and southern skies.
The discovery of the year was the first detection of gravitational waves.
Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
Latest observations suggest that cometary dust could be blocking light from strangely twinkling star.
Dust from pulverised comets rather than an alien megastructure could explain odd flicker of distant star.
Is this what we’re seeing around KIC 8462852 - a colossal megastructure built by alien intelligence? Probably not. The reality might be even more interesting.
There's a lot of speculation about a star behaving strangely in our galaxy. But even if it's not evidence of alien intelligence, it's sure to be an amazing discovery.
There are so many galaxies, you can write with them!
It’s National Science Week and this year the annual citizen science project run by ABC Science is astronomy-themed. No guesses for knowing that I’m excited about that! It’s also a nod to 2015 being the…
Our solar system is far from empty. A rogue asteroid or comet may have been responsible for the largest impact site yet discovered in Warburton in central Australia.

The largest meteorite impact site in the world may be right here in central Australia.
A bright fireball over the Atacama Large Millimeter/submillimeter Array, ALMA, in Chile, marks the fiery death of a small grain of space debris, high in the atmosphere.
Meteors have been seen since people first looked at the night sky. They are comprised of small pieces of debris, typically no larger than a grain of dust or sand, which continually crash into the Earth’s…
In space, no one can appreciate your artistic spacecraft rendering.
The European Space Agency’s Rosetta mission to land on comet 67P was one of the most audacious in space history. The idea of landing on a small chunk of icy rock 300m kilometres away from Earth and hurtling…
Comet Lovejoy on December 13 from the Astronomical Society of Victoria’s Astrophotography Observatory, Heathcote, Victoria.
If you are away from the bustle of the city these holidays, then try your luck at spotting a faint comet in the northern sky. Comet Lovejoy C/2014 Q2 is the fifth comet to be discovered by Brisbane amateur…
Rosetta deploys the Philae lander to comet 67P/Churyumov–Gerasimenko.

Scientists working with data sent back by the now-slumbering Philae lander have announced the discovery of organic molecules on the comet 67P/Churyumov-Gerasimenko. Finding organic compounds on 67P’s surface…
Philae’s first panorama shows a 360 degree view around the point of final touchdown. Superimposed is a sketch of what the lander team believes is Philae’s configuration.
The European Space Agency’s (ESA) pioneering Rosetta mission to land on a comet has been wildly successful, but now it appears that part of its aim, the exploration of the surface by the little Philae…
