I am a freelance science writer and former editor of Popular Astronomy magazine. I gained my PhD with a study of Sun-like stars.
Ceres

Dwarf planet Ceres may once have had an ancient, global ocean

Ceres, the largest body in the asteroid belt, may once have had an ocean beneath its icy crust, data from NASA’s Dawn spacecraft suggests.

A pair of black holes

Astronomers track down elusive pairs of supermassive black holes

Astronomers have devised a technique to seek out instances of double black holes, and have discovered five new pairs.

Titan pictured from the Cassini spacecraft

Blue planet Earth was once orange like Titan

Earth was like Titan once – an orange world engulfed in a thick haze of methane. Learning about its past may help understand exoplanets.

Schrodinger Crater

Lunar crater offers clues to impact that killed the dinosaurs

New studies of Schrödinger crater on the Moon are helping to further our understanding of the Chicxulub crater on Earth – ground zero for the asteroid impact that killed the dinosaurs.

Layered rocks on Mars

Quakes could boost chances of life on Mars

Seismic activity could release hydrogen gas that gives life on Mars the chance to exist, according to scientific research near fault lines on Earth.

Ice volcano

NASA’s Dawn probe finds ice volcano on dwarf planet Ceres

An icy volcano – known as a cryovolcano – has been discovered on the dwarf planet Ceres by NASA’s Dawn spacecraft.

Gas giant

Amateurs spot exoplanet with fast-changing orbit

The citizen science project Planet Hunters has detected an exoplanet that fell through the cracks of the automated computer searches.

Titan's southern polar vortex

NASA’s Cassini captures defiant clouds on Titan

NASA’s Cassini spacecraft has detected a massive cloud of hydrogen cyanide at Titan’s south pole which simply should not be there.

Star pulsations

Astronomers study star that spins slower on the inside

Astronomers have discovered a star where the interior rotates slower than the outer layers – the first time this has been detected in a main sequence star.

Planet Venus

Astronomers search for more planets like Venus

Astronomers are looking for planets like Venus. A “Venus zone” will help single out which exoplanets are most likely to imitate our own inhospitable neighbouring world.

Gas stream

Stream of gas stretches for 2.6 million light-years

The longest ever stream of hydrogen gas has been discovered acting as a bridge between galaxies 500 light years away.

Coldest white dwarf found orbiting nearby neutron star

A binary system of two dead stars has revealed the coldest, dimmest white dwarf discovered to date.
