First Space-Based Gravitational Wave Detector Gets Go-Ahead

The European Space Agency has approved the construction of the Laser Interferometer Space Antenna (LISA), the first space experiment to measure gravitational waves.
LISA will be able to observe gravitational waves of lower frequency than those detected on Earth, allowing it to spot phenomena such as black holes orbiting each other. [ more ]

European Space Agency gives LISA the nod for a 2035 launch

The European Space Agency has approved the Laser Interferometer Space Antenna (LISA) mission to detect gravitational waves from space.
The LISA mission will use three spacecraft to form a highly accurate equilateral triangle in space and will track changes in distances between solid gold-platinum test masses using laser interferometry. [ more ]

LIGO goes to space: ESA to proceed with LISA gravitational wave detector

The European Space Agency's Science Programme Committee has approved the LISA project, allowing construction to begin on the mission's three spacecraft.
The LISA project will use an interferometer placed 2.5 million kilometers apart in space to detect low-frequency gravitational waves, which Earth-based detectors cannot capture. [ more ]

Dr. Nergis Mavalvala Helped Detect the First Gravitational Wave. Her Work Doesn't Stop There

Dr. Nergis Mavalvala's life's work as a physicist is to understand how everything in the universe came to be.
Black holes, which don't give off light, can be studied through gravitational waves, ripples in spacetime caused by their gravity. [ more ]
