Description
Lensed quasars, gravitational lensing montage. This montage shows five lensed quasars and the foreground galaxies studied by the H0LICOW (H0 Lenses in COSMOGRAIL's Wellspring) collaboration. Using these objects astronomers were able to make an independent measurement of the Hubble constant (a measure of the size and age of the universe). They calculated that the universe is actually expanding faster than expected on the basis of our cosmological model. COSMOGRAIL is the COSmological MOnitoring of GRAvItational Lenses. Image published in 2017.
