Stars, Sprites, Clouds, Auroras

[Here](http://extremeinstability.com/) is a link to the photographer’s website. Mike is a well respected storm chaser who takes some of the most amazing structure shots of supercells. He’s got some great star trail shots and other astronomy related stuff on his website as well. Be

When a regular tornado is not enough

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).

Rosette Nebula narrowband

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

On June 3rd 1965, Ed White became the first American to step outside his spacecraft and let go, effectively setting himself adrift in the zero gravity of space. For 23 minutes White floated and maneuvered himself around the Gemini spacecraft, logging 6500 miles during his orbital stroll

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

Cloud Bomb – 33000ft over India

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.

Northern Lights, Norway

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

Milky Way over the Rocky Mountains at 11,000 Feet

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

In 1984, high above the Earth’s surface, an astronaut captured a satellite. Dale A. Gardner flies free using the Manned Maneuvering Unit and begins to attach a control device, dubbed the Stinger, to the rotating Westar 6 communications satellite

[Astronaut Dale A. Gardner, having just completed the major portion of his second extravehicular activity (EVA) period in three days, holds up a “For Sale” sign refering to the two satellites, Palapa B-2 and Westar 6 that they retrieved from orbit after their Payload

Aurora over Norway by Max Rive

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,

Red clouds and windmills

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

Comet ISON, shot by amateur astronomer Waldemar Skorupa

From the source: > 2013-11-16T04:09 ut; ASA 8H Newton FLI 16803 cropped, FOV ~3,5°; 3x180sL and 1x120s RGB Translated, I believe he’s using an [ASA 8H astrograph](http://www.optcorp.com/asa-8inch-8h-hyperbolic-astrograph-3inch-focuser-prokit.html) with a [Finger Lakes Imaging 16803 camera](http://www.optcorp.com/fli-proline-kaf-16803-ccd-camera-65mm-shutter.html). He’s probably using something like a [Losmandy G11](http://www.losmandy.com/g-11.html) to carry

Beautiful tornado touching down

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

Parseid meteor shower over Denver

Coronal Mass Ejection

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 –
