The lynx is a feline with keen eyesight and, in many cultures and traditions, a symbol of great insight and the supernatural ability to see through to the true nature of things.

Historically, Galileo was a proud member of Italy's Accademia dei Lincei (Academy of the Lynx), a scientific society devoted to the incisive investigation of the natural world. It was in the Accademia dei Lincei that the term ``telescope'' was first coined.

Lynx is a large area, high angular resolution, X-ray mission concept for the next decade. With its two orders of magnitude leap in sensitivity over Chandra and ATHENA, it will be able to penetrate into the epoch of reionization and detect X-rays from black holes lighting up the first galaxies. It will map the baryons in the Cosmic Web and in galactic halos and uncover the physics of environments ranging from young stars and their planetary systems to vast energy outbursts from supermassive black holes.

Much of the baryonic matter and the settings of the most active energy releases in the Universe are primarily visible in the X-rays. X-ray vision into this otherwise invisible Universe with Lynx is essential for true understanding of the origins and underlying physics of the cosmos.
