A low eccentricity low kerbol orbit is out, but not sure of anything beyond that.

...are you asking us yo do your homework for you?

I wouldn't be surprised if accelerometers are used to check on things like that. Maybe a strandbeast?

IRC with a channel that's invite only?

Unfortunately the standard good telescope options are at $200 (4-5" newtonians like the AWB Onesky and Orion Starblast) and $400 (8" dobs like the Zhummel Z8). Reflectors (especially ones with dobsonian mounts) let you get a great deal more aperture per $ than refractors or catadioptics. Astrophotography tends to require somewhat different (and much more expensive) equipment than visual. (hopefully subject to revision soonish)

And you get about 3-5 good oppositions in a row (weather permitting) followed by 5-7 bad ones. This was somewhat disheartening to discover as I started to get into amateur astronomy in 2007. Assuming I can stick the tracker on a small alt-as telescope mount, that won't be a problem. My Canon can absolutely shoot RAW thanks to the magic of CHDK, though that gets into what calibration tools would be needed and possible hard drive space concerns.

"Thing on top" would most likely be a Canon PowerShot SD1100 IS, barring spending on a DSLR. As for my profile pic, it's an SDSS g-band image of a nameless galaxy at z = 0.027. Admittedly I used the Stripe 82 data instead of DR7 and messed with the contrast and image size in DS9. Full size image and a colorized version using the g, r, and i bands as blue, green, and red, respectively.

Off topic: I'm confused about commonality/biomes/whatever. There seems to be a lot of, uh, sketchy info and the 3 step bug doesn't help. (Though pokevision's messing with the API does.) In any case, seeing all of 1 electric type, and 0 fire, fighting, dragon, or ghost types is vaguely troubling. (Also seeing almost no Duduos and even fewer Drowzees locally despite them supposedly being some of the most common) On the gym/competitive side, it looks like the meta involves getting a good vaporeon and/or how to beat them? Story-wise, are there any plans to flesh out the teams? Ethos, events, lore, various bragging rights rewards, etc like in Ingress? On topic: 5000 deaths in 18 hours would ultimately amount to ~1.2 million deaths over the course of a year. In 2013, the US saw just under 2.6 million deaths, so at this point, I'd expect this to be all over the news.

Admittedly my knowledge here is a bit sketchy, but axions are relatively light, right? So outside of some way for them to be consistently low energy they're hot dark matter when what is 'needed' is more cold dark matter?

You'll need a fully upgraded tracking station to see the asteroids in career mode.

Let me get back to on this is in a few months. Googling suggests that there might actually be some barn door type trackers that don't require a basement/garage full of machine tools?

Okay, how? Especially given that a "decent" DSLR is likely out of the price range. And, well, attempting to image the moon and starfields on a P&S is rather frustrating. (I really should take a shot at M31 at some point to demonstrate the pointlessness of trying astrophotography with a low end camera) You get the Magellanic clouds, Omega Centauri, 47 Tucanae, and better views of the Sagittarius/Scorpius objects than the northern hemisphere! That said, the crescent/first/last quarter moon through a telescope never gets old.

If you're out in a dark site, I'd skip the binaries and go for globular clusters (say, M4, M5, M13, M22, M92), open clusters (eg: M6, M7, M25, M29, fake ones like Cr399), nebulae (eg: M57, M27, M8, M20/21), and maybe a galaxy or two if they're in a favorable position. (eg: M81/M82) There's a good chance that it's Titan. I Iike Moons of Saturn and Moons of Jupiter for tracking the moon locations. The scope itself sounds like a fairly common small Newtonian form factor (~4.5", ~f/8) and reasonably capable. The eyepieces are pretty meh (kellnors, probably 0.965"/24.5 mm diameter), but as long as you can see things it doesn't matter much. If it can use 1.25" eyepieces and you have a budget, I'd be tempted to pick up a ~30 mm plössl to make finding things easier and maybe a 4-7 mm of some sort for planetary/lunar/double star views. How is it broken? We can do some troubleshooting and/or point you to places with more info (eg: Cloudy Nights) Eh, astrophotography is at least an order of magnitude more expensive. $400 can get you an 8" dob and some accessories with careful shopping(All hail the Zhummel Z8!) This seems far less budget breaking that putting at least a kilobuck each into a large apo, a mount, a DSLR, and Photoshop. Throw in a fifth kilobuck if you're like me and all your computer hardware is scavenged/would need to grab a recent macpro to run the image editing software.

Nifty, especially the visible phase angle for Mars(!). Out of curiosity, what sort of telescope and eyepieces are you using? It should be possible to see 2 bands (maybe more) on Jupiter, and both Saturn's Cassini division and Titan under good seeing. (colored filters may help with band details)

open KSP/saves/yoursavename/persistant.sfs in your favorite text editor, and do a search for those names. Note that you might have to edit in multiple places.

Meh on engagement -- large sections of the public only care if there are people in the spacecraft. and/or it is searching for life. Voting is apparently coming soon.

"Because this study only covered a very small patch of sky, the implication is that there should be many of these quiet black holes around the Milky Way. The estimates are that tens of thousands to millions of these black holes could exist within our Galaxy, about three to thousands of times as many as previous studies have suggested." [emphasis added] The Milky Way's stars are on the order of 1e10 solar masses, and the dark matter halo is on the order of 1e11 solar masses. Using a high estimate of 10 million and silly high mass of 100 solar masses for stellar black holes, that gives 1e9 solar masses. So this does not represent a significant fraction of dark matter. Note that my estimates of black hole masses were rather optimistic, and the population could easily amount to <1e7 solar masses.

Got a mathematical framework?

Sure we can. We can even get a Q value well above 1 if we use a fission initiator. More seriously, I would assume any KBO orbiter this century would use a fission reactor and an ion engine, sort of like JIMO would have.

Not really. Closest is if they're in an external seat.

The Mün's orbit has a 0° inclination, so eclipses happen every 39 hours 12 minutes The notable effects are a lack of solar power and in some cases nearby ground looks shadowed..

I'd personally be tempted to go with: RD-107 (kerolox lower stage), RL10 (hydrolox upper stage), AJ10 (hypergolic upper stage/post orbit maneuvers), and some monoprop RCS engine.

1. Dead as in what? The white dwarf stars we can observe are, well, white-hot. If we assume cooling times far longer than the present age of the universe, then one could presumably get more planet-like conditions. Sort of. 2. "fragments" as in what, and what do you mean by reactions? The high densities/pressures necessary for the weirdness of neutron star interiors cannot exist without lots of mass if that's what you're getting at. The exact amount would require rather detailed calculations, though. 3. Planetary masses mean you have nowhere near enough to maintain neutron degeneracy, and even electron degeneracy only becomes a thing somewhere in the Jupiter to brown dwarf range. Again, "size" is not that well defined, and especially not average. Do you mean mass, diameter, or something else, and what kind of planet (earth-like, super-earth, ice giant, gas giant, something else)? Ignoring the confinement problem, and assuming spheres with a density of 1e17 kg/m³, though: Body Mass (kg) Neutronium radius (m) Mercury 3.302e23 924 Earth 5.9736e24 2425 Neptune 1.0243e26 6290 Jupiter 1.8986e27 16549 So somewhere between <1 km to <17 km radius for most planet-like masses. But these numbers are only meaningful in a /r/theydidthemath/ sense. 4. I'm going to assume that "bigger" means higher mass main sequence star, in which case, yes. The greater luminosity means that the habitable zone is further out and due to the way the inverse square law works will have a greater volume. 5. If you organize things correctly, yes. Ish. Really the planets are orbiting the mutual center of mass of the two stars, and this works best if the stars are in a somewhat close orbit.

As best I'm aware, hot jupiters are actually fairly rare (~1-10% of sunlike stars). The super earths are still weird, especially given how they seem to be more common than terrestrial planets. Uh, note that the habitability of them is still ¯\_(ツ)_/¯ and anything above ~1.6 earth-radii is more of a sub neptune. Unrelated, why is U+1F728 (or for that matter, unicode plane 14) banned by the forum software? o_O

Since the weather in some places (eg: where I am) looks to be rather overcast, it looks like some of us will need to follow the NASA feeds? http://mercurytransit.gsfc.nasa.go http://sdoisgo.blogspot.com/2016/04/mercury-transit-on-may-9-2016.html
