Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
A moment of sadness with tears shed … then it was on with the work.
The annual Perseid meteor shower gives us a glimpse of remnants from the early formation of the solar system.
Was it a UFO? Was it a high-tech plane? Here’s what lucky people really saw over Scotland on February 29.
A meteor exploding over the South Pacific on February 6 was the biggest since the Chelyabinsk meteor in 2013. Here are some other fiery visitors.
Prepare to be amazed …
Dust from pulverised comets rather than an alien megastructure could explain odd flicker of distant star.
Is it a dwarf planet, an asteroid or a comet? All of the above? Well, with the latest results about Ceres, researchers aren’t entirely sure anymore.
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.
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…
The largest meteorite impact site in the world may be right here in central Australia.
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…
It was an exciting year in space exploration, with mind-blowing triumphs and heart-breaking failures. On Earth, new rockets and spacecraft were tested by space agencies and commercial ventures. SpaceX…
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…
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…
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…
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…
Exciting as it is (and it is incredibly exciting), the Rosetta mission is the latest in a history of comet exploration that has added to our knowledge of these icy dirtballs. Comets are usually just a…
