How did the universe begin? And what came before the Big Bang? Cosmologists have asked these questions ever since discovering that our universe is expanding. The answers aren't easy to determine. The beginning of the cosmos ...
After a six-week journey, LISA Pathfinder arrived at its destination today, an orbit around a point of balance in space where it will soon start testing technologies crucial for exploring the gravitational Universe.
While some technologies were created to make spacecraft move billions of miles, the Disturbance Reduction System has the opposite goal: To keep a spacecraft as still as possible.
Rumors are rippling through the science world that physicists may have detected gravitational waves, a key element of Einstein's theory which if confirmed would be one of the biggest discoveries of our time.
Producing and detecting gravitational fields at will using magnetic fields, controlling them for study, working with them to produce new technologies—it sounds impossible, but Prof. André Füzfa of Namur University has ...
Gravitational waves are tiny distortions of space-time caused by some of the most violent cosmic events such as colliding black holes. The observation of these 'ripples of space-time' requires exquisitely sophisticated new ...
ESA's LISA Pathfinder lifted off earlier today on a Vega rocket from Europe's spaceport in Kourou, French Guiana, on its way to demonstrate technology for observing gravitational waves from space.
The European Space Agency launched a rocket Thursday to carry two cubes of gold and platinum almost a million miles from Earth so scientists can see how they'll behave in a freefall—at a cost of more than $450 million.
The European Space Agency says it's preparing for the launch of a probe that will test technology for a future mission to measure gravitational waves.
The European Space Agency is postponing the launch of probe that will test technology for a future mission to measure gravitational waves.
