Artificial Intelligence Used to Discover Eighth Planet Circling Distant Star

"The discovery came about after researchers Christopher Shallue and Andrew Vanderburg and trained a computer to learn how to identify exoplanets in the light readings recorded by Kepler - the miniscule change in brightness captured when a planet passed in front of, or transited, a star. Inspired by the way neurons connect in the human brain, this artificial "neural network" sifted through Kepler data and found weak transit signals from a previously-missed eighth planet orbiting Kepler-90, in the constellation Draco."

Breakthrough Listen Releases Initial Results and Data from Observations of 'Oumuamua

"Breakthrough Listen - the initiative to find signs of intelligent life in the universe - is reporting preliminary results and making initial data available from its observations of the "interstellar visitor" 'Oumuamua. No evidence of artificial signals emanating from the object so far detected by the Green Bank Telescope, but monitoring and analysis continue. Initial data are available for public inspection in the Breakthrough Listen archive."

NASA: Preliminary Observations on the Management of Space Telescopes, Cristina Chaplain GAO

"GAO's ongoing work indicates that these projects are each making progress in line with their phase of the acquisition cycle but also face some challenges. For example, the current launch date for the James Webb Space Telescope (JWST) project reflects a 57-60-month delay from the project's original schedule. GAO's preliminary observations indicate this project still has significant integration and testing to complete, with very little schedule reserve remaining to account for delays. Therefore, additional delays beyond the delay of up to 8 months recently announced are likely, and funding available under the $8 billion Congressional cost cap for formulation and development may be inadequate."

Chairman Babin's Opening Statement: NASA's Next Four Large Telescopes

"It has been mentioned to me that with Hubble you could take a single picture into a meeting to show what was discovered but with W-FIRST you'll have to wallpaper their entire office. The capability has increased 100 times from Hubble. W-FIRST is a critical new flagship mission and we need to make sure it stays on course. The assets provided to NASA from the National Reconnaissance Office, or NRO, seem like a good fit for the mission but the program needs reasonable timelines and a realistic budget."

Going Off Source: Time Away With SETI In West Virginia

"20 years ago I made a trip to West Virginia to hang out with SETI researcher Jill Tarter and see how she searched the skies for evidence of life elsewhere. The region is very familiar to me since my wife and I have spent a lot of time there rock climbing and camping. What unfolded was part camping trip, part astronomy class, cruising around in diesel taxis, and a strange collision of ancient and modern hardware. More thoughts at the end of this story."
