Mars above the Keck Lasers (Custom Print)
This image shows an extremely bright Mars rising above the Keck telescopes on Hawaii’s Mauna Kea volcano. With 10-metre diameter primary mirrors, the Keck telescopes are two of the largest optical/infrared telescopes in the world. The adaptive optics lasers which they emit help to cancel out the blurring effects of turbulence in the Earth’s atmosphere. Each laser is about 0.5 m wide and they are extremely impressive to see in person. The lasers were not actually crossing; this is just a flattening effect of the 2D photograph.
