Email. Print. Trigeminal neuralgia (tic douloureux) is a disorder of a nerve at the side of the head, called the trigeminal nerve. This condition causes intense, stabbing or electric shock-like pain in the lips, eyes, nose, scalp, forehead and jaw.Although trigeminal neuralgia is not fatal, it is extremely painful.auses and Risk Factors. The pain of trigeminal neuralgia is usually caused by pressure on the trigeminal nerve at the base of the brain. The pressure can be result from: 1  A stroke that affects the lower part of the brain, where the trigeminal nerve enters. 2  A tumor that pushes on the nerve.
The Planck mission, launched on May 14, 2009, is measuring the Cosmic Microwave Background (CMB) over a broad range of far-infrared wavelengths, and to an unprecedented accuracy. The measurements will enable the extraction of essentially all of the information that can be obtained from CMB temperature anisotropies. Planck is expected to provide answers to many fundamental questions about the early history and evolution of our universe. Specifically, it is giving scientists the data needed to: set tight constraints on cosmological parameters
The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990, and remains in operation.ubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, Hubble's main mirror was found to have been ground incorrectly, compromising the telescope's capabilities.
