The spectrum of gravitational waves

Image: Gravitational waves are ripples in spacetime produced by the acceleration of very massive objects, such as black holes coming together and merging. 

Different objects in space produce gravitational waves of different timescales, ranging from milliseconds to billions of years. 

Some of these waves can only be observed from space. This is the goal of […]

Cassini’s wake: how might a spacecraft disturb its own measurements?

Simply by moving through the heavens, spacecraft change the space about them. Such interactions are invisible to the naked eye, but can endanger mission performance and safety. A new ESA Resarch Fellow study simulated the Cassini spacecraft in the vicinity of Saturn, checking the findings against actual space measurements. It reveals Cassini cast an ‘ion […]
