2016: the year in space and astronomy

Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
There are two broad ways to measure the expansion of the universe. One is based on the cosmic microwave background, shown here, along with our own galaxy viewed in microwave wavelengths. ESA, HFI & LFI consortia (2010)

From dark gravity to phantom energy: what’s driving the expansion of the universe?

The universe is expanding faster than expected, but we don't know what's driving it. Here are a few of the possible explanations, from dark energy to a modification of general relativity.

Australia’s part in the global effort to discover gravitational waves

The discovery of gravitational waves involved a team of more than 1,000 scientists from across the globe, including Australia. So how does such an international collaboration work?

Timeline: the history of gravity

It's taken centuries for our understanding of gravity to evolve to where it is today, culminating in the discovery of gravitational waves, as predicted by Albert Einstein a century ago.
2015 saw us complete our exploration of all nine planets (including dwarf planet Pluto) in our solar system. NASA

2015, the year that was: Science + Technology

2015 was a year where we expanded our view of the universe, embraced new technologies and got a hint of the profound changes to come.
General relativity isn’t only a powerfully descriptive theory, but there’s a beauty in its elegance.

The art and beauty of general relativity

Einstein's theory of general relativity is a triumph of reason and imagination, of art and science, with a profound beauty of its own.
