Gravitational Lensed System BG1429+1202 (image) Instituto de Astrofísica de Canarias (IAC) Share Print E-Mail Caption This the gravitational lensed system BG1429+1202. This picture shows how strong gravitational lensing by a massive galaxy (red color) acts on the light of a very distant galaxy (with bluish color), producing in this case four separate images and increasing the total flux. Without this effect, the detailed study of distant galaxies like BG1429+1202 requires the next generation of extremely large telescopes, like TMT and E-ELT.
