Zeropoint Posted August 27, 2016 Report Share Posted August 27, 2016 Tsk. You don't get supernovae on ocean floors in a properly run universe. Quote Link to comment Share on other sites More sharing options...
Christopher Posted August 27, 2016 Report Share Posted August 27, 2016 Tsk. You don't get supernovae on ocean floors in a properly run universe. So not only is that god guy refusing to comment on anything, even if he exists. He also does a poor job of running the Universe? I think he might be a bureaucrat.

tkdguy Posted August 29, 2016 Author Report Share Posted August 29, 2016 Not news, but an interesting article on how the night sky looks like on Mars http://www.space.com/28403-astronauts-mars-skywatching-phobos-deimos.html And from Alpha Centauri https://www.quora.com/Astronomy-What-would-the-night-sky-look-like-from-the-vantage-point-of-Alpha-Centauri I don't remember if this one has been posted here: Exoplanet in the Hyades cluster http://www.skyandtelescope.com/astronomy-news/exoplanet-in-hyades-star-cluster-0703201623/ Quote Link to comment Share on other sites More sharing options...
Old Man Posted August 30, 2016 Report Share Posted August 30, 2016 Strong candidate SETI signal received from HD 164595 (94 ly distant) pinecone and Christopher 2 Quote Link to comment Share on other sites More sharing options...
Cancer Posted August 30, 2016 Report Share Posted August 30, 2016 Strong candidate SETI signal received from HD 164595 (94 ly distant) Saw that. It's a solar twin (same spectral type as the Sun) with a known "warm Neptune" orbiting it. This is 16+/-3 earth masses, in a 40-day orbit. My reading is that "strong" is way too optimistic, and "possible" is a better word. OTOH, we've had an out-of-infinity discovery announced already in the last month, so let's go for a second.

Old Man Posted August 30, 2016 Report Share Posted August 30, 2016 The way I see it, we'd better hurry up and colonize that Proxima Centauri planet before these other guys do. Quote Link to comment Share on other sites More sharing options...

Nolgroth Posted August 30, 2016 Report Share Posted August 30, 2016 And of course, according to the article, the default "aliens are much more advanced than us" viewpoint had to be thrown out. Bah I say! Sniveling scientist bastards. Personally, I would have to say I'm much more interested in Planet Nine/X. That sounds really cool and not just because it is far away from the Sun. That creates story/game ideas. Quote Link to comment Share on other sites More sharing options...
Cancer Posted August 30, 2016 Report Share Posted August 30, 2016 Well, there is one thing: if we are detecting their signals now, at a distance of 94 ly, then they are ahead of us, if only by half a century or so. It'll be a few decades before detectable power from Earth's radio emissions will reach there. Quote Link to comment Share on other sites More sharing options...
Nolgroth Posted August 30, 2016 Report Share Posted August 30, 2016 Oh sure. Use things like math and logic to make an argument. THIS IS THE INTERWEBS DAG NABBIT. NOT. ALLOWED. Quote Link to comment Share on other sites More sharing options...
Cancer Posted August 31, 2016 Report Share Posted August 31, 2016 The way I see it, we'd better hurry up and colonize that Proxima Centauri planet before these other guys do. Proxima is about the same distance from them as we are, so we have a 90 l-y head start. Not that we can afford to get complacent, of course.

Cancer Posted August 31, 2016 Report Share Posted August 31, 2016 How old is HDwhatever? The best paper for that is a 2015 one in the European journal Astronomy & Astrophysics, and their subscription fee for non-Europeans is so insanely high that many USers will have to wait for the open access to kick in a few years ... before I can check that. Making some assumptions based on the lithium abundance in the US journal, it's close to the same age as the Sun, possibly a smidge older. L.

In other words humanity is so lonely in the cosmos, it started talking with itself. Quote Link to comment Share on other sites More sharing options...
DShomshak Posted September 2, 2016 Report Share Posted September 2, 2016 In this week's issue of the Economist, the cover story is about the Proxima planet (and exoplanet-hunting in general), while the Technology Quarterly section is about new and upcoming de3velopments in satellite technology.
