Aurora are at least somewhat predictable. When there a solar storm ejecting stuff in our direction, we’ll get active aurora a couple days later. At that point, you just need clear weather and preferably a new moon for darker skies. I live in Iceland,

Yeah, it’s annoying how some of the best photos aren’t in high resolution. The highest res I could find was this [1,247px × 809px version](http://www.lamauvaiseherbe.net/wp-content/uploads/2012/01/National_Geographic_concours_2011_02.jpg).
Hope you don’t mind, I brought down the blacks a bit and boosted the vibrancy ever so slightly to make it pop a bit more. Beautiful image! I attached your username to the image title at imgur for credit. If you’re unhappy with having
General relativity: “gravity” is the result of space and time curving in the presence of mass. One of the fundamental tenets is that gravity and acceleration are interchangeable and it follows that (locally) to a freefalling observer, space looks flat. That’s why you feel
Except it goes to +100 in Lightroom. Shoot out of grubby airline windows and you’ll see it’s an unfortunate necessity. Of course I would rather no clarity adjustment was needed.
So there’s a lot wrong with this image. It’s, at best, a poor merging of two images. 1.) the city is nicely in focus, showing a higher aperture. The stars are *way* out of focus, that’s just not possible with how the city was
Shot details: 5-shot pano at about 18mm, f2.8, 20sec, ISO6400, AWB taken at Rainbow Curve in Rocky Mountain National Park. As I’m sure everyone knows, neither the Milky Way or Airglow was that bright to your naked eyes, the very high ISO brought it
No, I do. I’m self employed and unfortunately it looks like I’m going to be booked solid until roughly October. At that point, yeah, I might be able to get a little bit of late-year hiking in, but nothing like the John Muir Trail

From the photographer’s [Flickr](https://www.flickr.com/photos/apojapo/13297070714/in/faves-sidaths/): >The light on the right is coming from the ”city” of Svolvaer. The aurora is the result of 3 exposures taken directly after each other so I have been a bit creative on that part.
Another option for travel, which allows for faster than light speeds without violating the laws of physics, is something called the [Alcubierre Drive](http://en.wikipedia.org/wiki/Alcubierre_drive). This is the same drive that allows “warp” speed in Star Trek. Although Star Trek is a work of science fiction,
The more pics I see the more I think that Pluto could be a candidate for a early planet flung to the outer system. Maybe a 1 in a trillion extra solar capture of a wandering planet? That strange ice looks like what might

NASA spends about 10 bil a year on average. In 2011, the budget on space represented only 0.5% of the US’s federal budget (18.4 billion / 3.4 trillion). Relatively speaking, space exploration has a very small budget and the amount of discoveries and helpful
I’m aware; my undergraduate degree was in mechanical engineering. That is why I didn’t say that turbines produce electricity, but rather compared it to other electricity-producing turbines. You have a good point, though, that these systems must be tied to a generator to make

I like to talk about tornadoes when I can… This is a tornado in the dissipating or “rope” stage. In supercell (rotating) thunderstorms, cooler, stable air wraps around the rotational center. This is the rear flank downdraft (RFD) and it can choke off the

Hurricanes, and mid-latitude cyclones like the one in the pic, get their energy out of the atmosphere in different ways. Hurricanes get their energy from the heat released by tons of water vapor condensing into clouds and rain (it’s the reverse process of water
Per NASA: **On August 31, 2012 a long filament of solar material that had been hovering in the sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The
It funny how we are 2 completely different people, personally I love the cold weather, but I dont mind the warm. I feel like its always easier to warm up then to cool down. In the summer time when it gets to +25°C –
