Interest in Earth-like planets orbiting within the habitable zone of their host stars has surged, driven by the quest to discover life beyond our solar system. But the habitability of such planets, known as exoplanets, is influenced by more than just their distance from the star.

Astrophysicists Uncover Supermassive Black Hole/Dark Matter Connection in Solving the ‘Final Parsec Problem’

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles.

Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding “final parsec problem” in astronomy.

The research is described in ...

New Dawn for Space Storm Alerts could help Shield Earth’s Tech

Scientists say it is now possible to predict the precise speed a coronal mass ejection (shown left in an artist's impression) is travelling at and when it will smash into Earth (bottom right moving in our direction) – even before it has fully erupted from the Sun (top right).

Space storms could soon be forecast with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth.

Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is traveling at and when it will smash into our planet—even before it has fully erupted from the sun.

CMEs are bursts of gas and magnetic fields sp...

Europe’s next big space mission – a telescope that will hunt for Earth-like rocky planets outside of our solar system — is on course to launch at the end of 2026.

PLATO, or PLAnetary Transits and Oscillations of stars, is being built to find nearby potentially habitable worlds around Sun-like stars that we can examine in detail.

The space telescope will blast into orbit on Europe’s new rocket, Ariane-6, which made its maiden flight last week after being developed at a cost of €4billion (£3.4billion).

Dr David Brown, of the University of Warwick, is giving an update on the mission at the Royal Astronomical Society’s National Astronomy Meeting at t...
