Summer, but not as hot as it was the previous couple of weeks. For now, we have some badly needed rain. |

In Kansas, USA we just got off some official "excessive heat warning" days. Plus lots of Thunder Storms and some rain.... "You are entitled to your own opinion but not to your own facts." Senator and Professor Patrick Moynihan In detail I am a Big Picture sort of guy. |

https://newatlas.com/space/neutron-images-find-zinc-culprit-arecibo-radio-telescope-collapse/ Almost three years after the event, neutron scans by the Oak Ridge National Laboratory have uncovered the cause of the platform collapse that resulted in the destruction of the 1,000-ft (300-m) Arecibo Observatory radio telescope. As part of this effort, Adrian Brügger, director of Columbia University’s Robert A. W. Carleton Strength of Materials Laboratory, took whole sections of the failed cable sockets, complete with cables and socket liners, and subjected them to neutron scans at Oak Ridge's High Flux Isotope Reactor (HFIR). In the case of Arecibo, the scans allowed Brügger to make cross section images of the cable sockets and determine which cables slipped and by how much, even if they were still buried inside the zinc lining. What became apparent was that as cables were subject to the stress of supporting the platform they began to fray. This, in turn, caused the zinc to flow under the tension. Eventually, the zinc flowed so much that the sockets failed and the cables were pulled out entirely. Exactly how much of this slippage occurred before or during the event could not be determined. What is known is that two cables failed before the collapse, with a third failure causing the platform to fall. |

And another one to drop in. Nasa's James Webb Space Telescope may have discovered tentative evidence of a sign of life on a faraway planet. |
