An international team of astronomers has announced the results of a comprehensive search for a background of low-frequency gravitational waves. These light-year-scale ripples, a consequence of general relativity, permeate all of spacetime and could originate from mergers of the most massive black holes in the Universe or from events occurring soon after the formation of the Universe in the Big Bang.

An international team of researchers has found that the black hole at the centre of our galaxy, Sagittarius A*, not only flares irregularly from day to day but also in the long term. The team analysed 15 years' worth of data to come to this conclusion.

The upcoming satellite experiment LiteBIRD is expected to probe the physics of the very early Universe if the primordial inflation happened at high energies. But now, scientists show it can also test inflationary scenarios operating at lower energies.

Astronomers have identified a potential clue to how the universe became reionized after the Big Bang. The researchers identified a black hole, a million times as bright as our sun, that may have been similar to the sources that powered the universe's reionization.

An international scientific group has managed to measure for the first time oscillations in the brightness of a neutron star during its most violent moments. In just a tenth of a second, the magnetar released energy equivalent to that produced by the Sun in 100,000 years.

In Lovecraftian horror, the Universe is filled with 'dark planets' ungraced by the light of a host star. New research shows that reality might be even scarier. An international team of astronomers has found about 100 planets floating freely in space rather than orbiting stars.

Astronomers have produced the most comprehensive image of radio emission from the nearest actively feeding supermassive black hole to Earth. The emission is powered by a central black hole in the galaxy Centaurus A, about 12 million light years away.

Proposing an alternative model for how the universe came to be, a team of astrophysicists suggests that all black holes - from those as tiny as a pin head to those covering billions of miles - were created instantly after the Big Bang and account for all dark matter.
