. This mosaic image shows part of the left side of NASA's Curiosity rover and two blast marks from the descent stage's rocket engines. The rim of Gale Crater is the lighter colored band across the horizon. The back of the rover is to the left. The blast marks can be seen in the middle of the image. Several small bits of rock and soil, which were made airborne by the rocket engines, are visible on the rover's top deck. // Credit: NASA/JPL-Caltech

... In one situation, we can use light from quasars to probe the material between us and them because that light may pass through one or more galaxies or gas clouds on its way to us. The gas inside the galaxies or the intergalactic clouds acts then as a filter, absorbing selected wavelengths from the quasar light. ... Light from a quasar must pass through clouds of gas and even faint galaxies -- each leaving its imprint on the light -- before we receive it here on Earth. ... Gravitational lensing . ...
