Zeropoint Posted April 19, 2014 Report Share Posted April 19, 2014 Blind luck asteroids haven't hit a major city yet Whoa. I mean, holy crap. Also, how can 26 nuke-sized explosions go off without anyone noticing? I'll be keeping an eye on this topic. Quote Link to comment Share on other sites More sharing options...
Old Man Posted April 19, 2014 Report Share Posted April 19, 2014 Obviously someone noticed, or we wouldn't have a count of 26. Quote Link to comment Share on other sites More sharing options...

Spence Posted April 19, 2014 Report Share Posted April 19, 2014 This is truly frightening. Maybe, the tenancy of pretty much everyone to extremely overstate threats in an effort to 'shock' stimulate interest or more frequently funding has made me take most of these style of claims with a grain of salt. After we get a gander at what they are using as their data pool and some of their actual information, then we'll see. Could it be true? Absolutely. Will I believe them based on one article repeated on Yahoo? Not Spence "the glass is half empty" Sanders drunkonduty 1 Quote Link to comment Share on other sites More sharing options...

Old Man Posted April 22, 2014 Report Share Posted April 22, 2014 An updated chart of Goldilocks planets, sorted by size and habitable zone, at http://news.nationalgeographic.com/news/2014/04/140417-exoplanet-interactive/#close-modal . Newly discovered Kepler-186f is 493 light years away, so we'd better get going if we want to get there in time for dinner. tkdguy 1 Quote Link to comment Share on other sites More sharing options...
Cancer Posted April 23, 2014 Report Share Posted April 23, 2014 Another exoplanet foundFinally chased down the tech paper about this. Five planets known in the system. There is room for another planet between the one in the HZ and the next known one inward, and could be yet more planets further out (which plausibly might not make transits and hence would be undetectable). There is no spectroscopic orbit; they have solid transit data but they are using an assumed stellar mass and there is no mass measurement for the planet. (That lack of spectroscopic orbit is why we have to speculate about the planet composition and mass rather than knowing the latter and having high confidence in the former.) The orbital period and assumed mass plus the transit timings give both a stellar and planetary radius (and the stellar radius is OK with the assumed stellar mass, but there's considerable slop there). The known planet orbits are coplanar to within 3 degrees. tkdguy 1 Quote Link to comment Share on other sites More sharing options...

tkdguy Posted April 27, 2014 Author Report Share Posted April 27, 2014 Vesta can be seen with binoculars right now, if you know where to look. It's in Virgo right now. I was looking for it last week, although I couldn't make a positive identification. Quote Link to comment Share on other sites More sharing options...

BlueCloud2k2 Posted May 10, 2014 Report Share Posted May 10, 2014 Might not be as practical in space though. A Graser would be better as you can aim it and it would be a light speed weapon. Missiles packed with Antimatter? Vulnerable to being shot down and the blast wave would most likely not do as much damage or be as controllable as a laser. No to mention that if it was shot down close to your ships/base the blast wave would cook your people. Nuclear weapons would actually be safer in this instance. Antimatter has too much potential of killing friendlies if the missile is damaged. Quote Link to comment Share on other sites More sharing options...
