What is the purpose of ‘evolved Laser Interferometer Space Antenna’ (eLISA) project?
(a) To detect neutrinos
(b) To detect gravitational waves
(c) To detect the effectiveness of missile defence system
(d) To study the effect of solar flares on our communication systems
- The European Space Agency is leading the evolved Laser Interferometer Space Antenna (eLISA) mission, aimed at detecting and precisely measuring gravitational waves, making statement 2 correct.
- LISA will be the first space-based detector dedicated to gravitational waves, which are produced by supermassive black holes in the centres of galaxies.
- Additionally, eLISA will measure signals emitted by thousands of compact binary star systems in the Milky Way.
