New views on the origins of carbon
White dwarfs found to have more mass than expected.
Every carbon atom in the Universe was created by stars, through the fusion of three helium nuclei, but which types of...
Pōniuāʻena makes its mark far from Hawaii
It’s the second-most distant quasar ever detected.
The discovery of the second-most distant – and thus second oldest – quasar ever detected may force a rethink of how b...
Astrophysicists find the exoplanet they wanted
It’s the size of Neptune and orbiting a young star.
An exoplanet the size of Neptune has been discovered around a small young star about 32 light-years from Earth, endin...
Quasar jets thousands of light-years long
Scientists take a good look at Centaurus A.
The very-high-energy gamma ray emission from quasars are not concentrated in the region close to their central black ...
The theory of how black holes grow
New model aims to predict accretion or merger.
Astrophysicists in the US have developed a theoretical model for black holes to predict if growth by gas accretion or...
15 platters that matter
Rare images of planet-forming discs.
Astronomers have captured 15 new images of the inner rims of planet-forming discs hundreds of light-years away that s...
Do hungry galaxies eat their neighbours?
Modelling suggests that’s how big ones get bigger.
Exactly how massive galaxies attain their size is poorly understood, not least because it happens over billions of ye...
Star dance around a black hole
ESO telescope, and a lot of hard work, prove Einstein right.
After nearly three decades of work, scientists have revealed that a star orbiting the supermassive black hole at the ...
Thar she blows – up in space
Most energetic outflow from a distant quasar detected.
Astronomers say they have detected the most energetic wind ever measured from any quasar. It is travelling at nea...
A close look at a black hole’s jet
Data from the Event Horizon Telescope keeps on giving.
Creating the first direct image of a black hole is a hard act to follow, but it seems there are more goodies to be ha...
Another twist in the dark matter story
Electromagnetic signals don’t deliver the evidence.
US researchers say we can rule out dark matter being responsible for mysterious electromagnetic signals previously ob...
Quasar tsunamis rip through space
The phenomenon carries more energy than a gamma-ray burst.
This artist's concept of a distant galaxy with an active quasar at its centre shows the large amount of energy genera...
