Dead Stars Found Whipping Around Each Other in Minutes

Two dead stars have been spotted whipping around each other every seven minutes.

The newfound dynamic duo, officially known as ZTF J1539+5027, is the second fastest pair of orbiting dead stars, called white dwarfs, found to date. Artwork Jorge Lugo

Discovering exoplanets with gravitational waves

Researchers suggest how LISA can detect exoplanets orbiting white dwarf binaries everywhere in our Milky Way and in the nearby Magellanic Clouds.

ESA: A unique experiment to explore black holes

What happens when two supermassive black holes collide? Combining the observing power of two future ESA missions, Athena and LISA, would allow us to study these cosmic clashes and their mysterious aftermath for the first time.

LISA & LISA Pathfinder

LISA will be a large-scale space mission designed to detect one of the most elusive phenomena in astronomy - gravitational waves. With LISA we will be able to observe the entire universe directly with gravitational waves, learning about the formation of structure and galaxies, stellar evolution, the early universe, and the structure and nature of spacetime itself.

The LISA Pathfinder Mission successfully paved the way for the LISA mission by demonstrating the key technologies for a large gravitational wave observatory in space. The results show that LISA Pathfinder is working to a precision better than required for LISA. The LISA Pathfinder mission was launched on 3rd December 2015 and ended in July 2017. 

The LISA Consortium

The LISA Consortium is committed to supporting the LISA mission. It includes all the main investigators involved in the highly successful LISA Pathfinder mission, a number of scientists who worked on the ground-based LIGO, Virgo, and GEO projects, and a number who worked on the Laser Ranging Interferometer on the GRACE Follow-On mission, thus making full use of the expertise accumulated so far. The LISA Consortium proposed and submitted the white paper The Gravitational Universe which was accepted for the ESA L3 slot.

The path to LISA: a unique collaboration

The LISA Pathfinder mission, which demonstrated key technologies for the LISA gravitational-wave observatory was enabled by a unique collaboration.
