Glowing X-rays around distant galaxies can’t come from dark matter particles, new research shows. The mysterious glow failed to show up in the dark matter halo around the Milky Way, astrophysicists report in the March 27 Science. “It seems to be the final nail in the coffin of the dark matter interpretation,” says astroparticle physicist…

Our galaxy is a whole lot bigger than it looks. New work finds that the Milky Way stretches nearly 2 million light-years across, more than 15 times wider than its luminous spiral disk. The number could lead to a better estimate of how massive the galaxy is and how many other galaxies orbit it. Astronomers…

WASP-76b — a hard rain’s gonna fall The team have been able to determine the characteristics of WASP-76b’s relationship with its parent star which give rise to the extraordinary atmospheric phenomena observed. WASP-76b is tidally locked, much as the moon is around the Earth, meaning the planet constantly orbits its host star with the same…

The water you blame the messenger for? Water ice was first detected on Mercury by astronomers on Earth, who saw telltale signs of the molecule in radar observations of the diminutive world. In 2011, the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft passed the planet, confirming the presence of water ice within the…

Astronomer Cliff Johnson was peering into deep space before dawn when something close to Earth interrupted his view. He and colleagues were searching for dwarf galaxies snuggled up to the Milky Way using the Victor M. Blanco 4-m Telescope in Chile. The team was remotely operating the scope from a room at Fermilab in Batavia,…

Katherine Johnson, who has died at the age of 101, was an amazing woman. But up until a few years ago, hardly anyone had heard of her or her achievements. She was a mathematician and she worked for NASA. But on paper, neither of those facts would make her stand out from the crowd. Add…
