Webb is on its way

Launched on Christmas Day morning, the Webb telescope has got about six weeks of travel to get to L2, the second Lagrange point, which is 1.5 million kilometers away. (LaGrange points are where Earth’s gravity doesn’t affect objects in orbit.) With a bigger mirror than Hubble and in a much higher orbit, Webb will be able to peer much farther back in time (history) perhaps even to see the first galaxies. Will primarily look at the universe in the infrared wavelength versus Hubble’s optical and ultraviolet wavelengths. Should be interesting.
