Astronomers traced a single star as it passed close to the black hole at the centre of our galaxy, and detected the telltale signature of Einstein’s gravity in action.

An extreme laboratory in space involving three dead stars has shown that all objects really do accelerate identically, proving Einstein right.
Exactly 99 years after Einstein's theory of general relativity was proven right in our own solar system, scientists show that it also holds true for entire galaxies.
Stephen Hawking was a highly creative scientist, pushing past assumptions and playing with "what if" scenarios to take physics to new levels.
A future that continues to have increasingly fast computing depends on quantum physics – but research is showing that there are limits to how fast quantum computers can go.
Controversial new study challenges contemporary thinking about what the universe is made of.
Hawking proved that the Big Bang was physically possible.
Is dark energy just an illusion, as is often suggested? To resolve the dilemma, interpreting the basic principles of general relativity in a complex Universe may need a rethink.
Astronomers report the first ever measurement of light bending around a star other than our own.
These ripples in the very fabric of the universe were hypothesized by Einstein a century ago. Now scientists have detected them for the third time in a year and a half – ushering in a new era in astrophysics.
Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
From the discovery of gravitational waves, to the Pokémon Go phenomenon to the Census debacle, it's been a big year in science and technology.
Einstein's theories of relativity underpin our understanding of the universe, yet they're not taught in high school. How can we change that?
The OzGRav Centre of Excellence for Gravitational Wave Discovery will enable Australian researchers to be at the forefront of gravitational wave astronomy.
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.
Something mysterious is pulling our Milky Way through space at a much faster rate than expected. So what could it be?
There's a good reason you should care about the discovery of gravitational waves, even if you don't understand the science.
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?
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.
Here's a LIGO insider's description of how he got the news of a phenomenon that had first been theorized 100 years ago.
