Old Man Posted January 27, 2016 Report Share Posted January 27, 2016 Parallel to that there have been some developments in cryosuspension tech, which is probably the only hope for interstellar travel in one "lifetime" for the foreseeable future.

DShomshak Posted January 28, 2016 Report Share Posted January 28, 2016 This month's Scientific American has three space-related articles. The lead story is about the proposed inference of Planet X. The article notes that even the astronomers who propose Planet X are cautious, because there's a long history of similar inferred bodies that turned out not to exist. It's worth searching for Planet X, but it's far from a sure thing. The issue also has a brief report on observation of the curious "Jellyfish" galaxies, and a reminiscence by comet-hunter David Levy (of Shoemaker-Levy 9 famE). Apart from space, Michael Shermer's "Skeptic" column, "Afterlife for Atheists," reported on research to cryopreserve brains in hopes the information in the synapses -- the connectome -- can be used to reconstruct the personality later. Shermer finds the proposal interesting, but is far from convinced. Dean Shomshak Quote Link to comment Share on other sites More sharing options...

Cancer Posted February 1, 2016 Report Share Posted February 1, 2016 New talk about planet X. Or is it planet IX now. (Not as catchy) http://www.sciencemag.org/news/2016/01/feature-astronomers-say-neptune-sized-planet-lurks-unseen-solar-system The tech paper about this is here. It may not be behind the subscriber wall; the page says "free article". Since my workstation is on the site license for the journal, I can't reliably tell whether that's really open or not without going home, which won't happen for a few hours.

Cancer Posted February 11, 2016 Report Share Posted February 11, 2016 Yeah, the evidence looks quite convincing for detection of gravitational waves from a black hole merger, detected last September 14. A 29 solar mass black hole merged with a 36 solar mass black hole, about 1.3 billion years ago (i.e., 1.3 billion light years away), forming a 62 solar mass single black hole. 3 solar masses was converted into gravitational waves energy and radiated away over about 20 milliseconds.

L. Marcus Posted February 11, 2016 Report Share Posted February 11, 2016 ... Three solar masses worth of gravity waves? That can't be healthy! Quote Link to comment Share on other sites More sharing options...
Cancer Posted February 11, 2016 Report Share Posted February 11, 2016 In the immediate vicinity, it surely wasn't. 1.3 billion light-years away, we can be more blase. Quote Link to comment Share on other sites More sharing options...
