Record-breaking fast radio burst offers path to weigh the Universe

Scientists report on their discovery of the most ancient and distant fast radio burst located to date, about eight billion years old. The discovery smashes the team's previous record by 50 per cent. It confirms that fast radio bursts can be used to measure the 'missing' matter between galaxies.

Pulsars may make dark matter glow

The central question in the ongoing hunt for dark matter is: what is it made of? One possible answer is that dark matter consists of particles known as axions. A team of astrophysicists has now shown that if dark matter consists of axions, it may reveal itself in the form of a subtle additional glow coming from pulsating stars.

Astronomers Discover first step toward planet formation

Scientists succeeded in capturing the conditions on the eve of planet formation, as the disk was smooth with no signature of planets. They also found that the dust had grown significantly in the outer part of the disk and that the dust concentration was higher than normal in the inner part of the disk.

Plot thickens in hunt for ninth planet

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand the rotation of galaxies.

Scientists discover the highest energy gamma-rays ever from a pulsar

Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light. This observation is hard to reconcile with the theory of the production of such pulsed gamma rays.

New proof for black hole spin

The supermassive black hole at the heart of galaxy M87, made famous by the first picture of a black hole shadow, has yielded another first: the jet shooting out from the black hole has been confirmed to wobble, providing direct proof that the black hole is spinning.
