Spacetime - a creation of well-known actors?

Most physicists believe that the structure of spacetime is formed in an unknown way in the vicinity of the Planck scale, i.e. at distances close to one trillionth of a trillionth of a metre. However, careful considerations undermine the unambiguity of this prediction.

Astronomers find elusive star with origins close to Big Bang

Astronomers have found what could be one of the universe's oldest stars, a body almost entirely made of materials spewed from the Big Bang.

Most detailed observations of material orbiting close to a black hole

The GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky Way.

Scientists refine the search for dark matter

Researchers have developed a more effective technique in the search for clues about dark matter in the universe. They can now analyse much larger amounts of the data generated at CERN.

Superflares from young red dwarf stars imperil planets

Flares from the youngest red dwarfs surveyed are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their stars.

A new era in the quest for dark matter

In a review that was published this week, physicists argue that the time has come to broaden and diversify the experimental effort, and to incorporate astronomical surveys and gravitational wave observations in the quest for the nature of dark matter.
