Roger Penrose helped resurrect Einstein's general theory of relativity, and Reinhard Genzel and Andrea Ghez showed there was a black hole in the middle of our galaxy.
This image of the NGC 1398 galaxy, which is located in the Fornax cluster, was taken with the Dark Energy Camera.

Dark energy is probably a sea of constant energy in empty space itself, according to new research.

The h-index has become an indicator of quality for many researchers and may influence the allocation of research funds. But some question its value.
Finally dragged out of the shadows.

Scientists turned Earth into one giant telescope to capture the uncapturable.
The crucial phase of our discovery of black holes took place in a suitably dark period of human history – World War II.
An artist’s impression of the path of star S2 as it passes very close to the supermassive black hole at the centre of the Milky Way. The very strong gravitational field causes the colour of the star to shift slightly to the red. (Size and colour exaggerated for clarity.)
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.
Triple star system involving a pulsar suggests Einstein was right.
An extreme laboratory in space involving three dead stars has shown that all objects really do accelerate identically, proving Einstein right.
When galaxies align.
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.
Hawking had a cult-like following among academics and non-academics alike.
Stephen Hawking was a highly creative scientist, pushing past assumptions and playing with "what if" scenarios to take physics to new levels.
How fast can quantum computing get? Research shows there’s a limit.
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.

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.
Gravity of a white dwarf star warps space and bends the light of a distant star behind it.

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.
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.
Hi Juno, welcome to Jupiter.
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 are still not taught in school.
Einstein's theories of relativity underpin our understanding of the universe, yet they're not taught in high school. How can we change that?
Gravitational waves are produced by some of the most extreme events in the universe.
The OzGRav Centre of Excellence for Gravitational Wave Discovery will enable Australian researchers to be at the forefront of gravitational wave astronomy.
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)
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.
