Gravity mission still unearthing hidden secrets

Despite ESA's GOCE mission ending over seven years ago, scientists continue to use this remarkable satellite's gravity data to delve deep and unearth secrets about our planet. Recent research shows how scientists have combined ...

Why slow-pouring coffee makes a tower of liquid in your cup

When a droplet of coffee hits the liquid surface in the cup, a characteristic tower of coffee forms for a very short time, sometimes even with a new droplet on top. In a paper that appeared in Physical Review Fluids today, ...

Factoring in gravitomagnetism could do away with dark matter

Observations of galactic rotation curves give one of the strongest lines of evidence pointing towards the existence of dark matter, a non-baryonic form of matter that makes up an estimated 85% of the matter in the observable ...

Placing cosmological constraints on quantum gravity phenomenology

A description of gravity compatible with the principles of quantum mechanics has long been a widely pursued goal in physics. Existing theories of this 'quantum gravity' often involve mathematical corrections to Heisenberg's ...

Taking gravity from strength to strength

Ten years ago, ESA launched one of its most innovative satellites. GOCE spent four years measuring a fundamental force of nature: gravity. This extraordinary mission not only yielded new insights into our gravity field, but ...

Smoother and safer flying

Flying through a patch of severe and unexpected turbulence is an unforgettable, unsettling and sometimes painful experience for tens of thousands of passengers each year.

Gravity waves influence weather and climate

Gravity waves form in the atmosphere as a result of destabilizing processes, for example at weather fronts, during storms or when air masses stroke over mountain ranges. They can occasionally be seen in the sky as bands of ...
