Powerful explosions known as supernovas, triggered when a massive star dies, can shake up space and blast the cosmos with a burst of high-frequency gravitational waves.
It detects so-called high-frequency gravitational waves - but there should also be low-frequency gravitational waves, and to capture those the ESA is already working on an incredibly ambitious project called the Evolved Laser Interferometer Space Antenna (eLISA).
Astrophysicists are excited by the prospects: while LIGO-like interferometers are sensitive to the high-frequency gravitational waves from merging neutron stars (a few hundred hertz), PTAs would detect the long-wavelength, very low-frequency waves from binary black holes in distant galaxies (see graph on facing page).
