Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars

In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. ...

Scientists uncover hidden forces causing continents to rise

Scientists at the University of Southampton have answered one of the most puzzling questions in plate tectonics: how and why "stable" parts of continents gradually rise to form some of the planet's greatest topographic features.

A new 'guest star' will appear in the sky in 2024 − a space scientist explains how nova events work and where to look

The stars aren't fixed and unchanging, unlike what many ancient people thought. Once in a while, a star appears where there wasn't one before, and then it fades away in a matter of days or weeks.

520-million-year-old worm fossil solves mystery of how modern insects, spiders and crabs evolved

A new study led by researchers at Durham University have uncovered an incredibly rare and detailed fossil, named Youti yuanshi, that gives a peek inside one of the earliest ancestors of modern insects, spiders, crabs and ...

When copper becomes transparent: European XFEL creates exotic matter

Experiments at European XFEL generate states of matter that are close to what occurs in the interior of planets or in the imploding capsule of an inertial fusion reactor. At the same time, they open up a way to measure ultra-short ...
