Letter: Astronomy event

I attended an extraordinary astronomy event at the Teton Springs Lodge in Teton Valley on Saturday night, Aug. 22. The executive director of the Keck Observatory, Hilton Lewis, gave a presentation of the layout and some of the accomplishments of the observatory. It consists of two 10m diameter telescopes, with adaptive optics, for visible light and infrared frequencies, and is located on top of 14,000-foot Mauna Kea, Hawaii. It’s advertised that this observatory is the most productive astronomical observatory and can achieve image quality better than the space-based Hubble Telescope. Astronomers and scientists have used Keck telescope data to: (1) discover that the universe is not only expanding but is accelerating due to dark energy; (2) successfully measure the farthest galaxy ever recorded; (3) prove the existence of a supermassive black hole at the center of our own Milky Way galaxy; and (4) discover planets in the habitable zone of sun-like stars. He said there is not yet any confirmed evidence of alien life, but there is overwhelming probability that it exists. He invited people to join the Keck Nation e-community at keckobservatory.org. He recommended use of the “Sky Guide App.”
