Beautiful Photo Collage of the Sun Shows Different Wavelengths of Light

collage

Our sun can look very different in photographs depending on the wavelength of light you’re trying to capture. Some photographs show the sun as a glowing white ball, while others capture hotter areas in a cold blue color. NASA recently took a collection of sun photos shot at different wavelengths and combined them into the beautiful photo collage seen above (here’s a higher-res version).

That Photon Hitting Your Camera Sensor Took Thousands of Years to Arrive

sensorlight

How long does it take for a photon from the Sun to reach your camera sensor (or film) and help form a photograph? If you answered “8 minutes,” you’d be kind of right, and but also kind of wrong. An answer that’s more correct is “at least tens of thousands of years.”

Photographer Captures Rare Photograph of a Sprite with an Aurora

spriteaurora0

Check out this aurora photograph captured last Friday night by photographer Mike Hollingshead. See those small red squiggly lines in the sky? That’s an extremely rare form of lightning called a sprite. This photograph is one of the only times a sprite and an aurora have been captured in the same frame.

What Landscape Photos Would Look Like if Earth Had a Ring Like Saturn’s

top1

Last month we shared some photo illustrations by science artist Ron Miller that showed what the night sky would look like if other planets in our solar system replaced the moon. Now Miller is back again with an equally interesting concept: what would landscape photos look like if Earth had a ring like Saturn’s?

Beautiful Photograph of a Hurricane… On the North Pole of Saturn

rosesaturn

Photographs of storm systems as seen from airplanes or satellites aren’t too uncommon these days, but have you ever seen one that looks like this? Probably not, because this photograph is out of this world — literally. It’s titled “The Rose,” and shows the spinning vortex of a gigantic hurricane on the surface of Saturn.

Scientists May Do Quantum Entanglement Test with a 400mm Nikon Lens on the ISS

ISSentanglement

Albert Einstein once described quantum entanglement as “spooky action at distance.” The basic idea behind it is that certain things (e.g. particles, molecules) can interact with each other instantly (or nearly instantly) regardless of how far apart they are. For example, pairs of photons can affect one another when separated by vast distances, with the effects occurring even faster than light could have traveled between the two points.

The Pale Blue Dot: A Portrait of Earth Shot From More Than 4 Billion Miles Away

1990 Pale_Blue_Dot NASA

Seeing as the Voyager-1 spacecraft has been in the news recently, here’s the story of a very special photograph that it took 23 years ago known as “The Pale Blue Dot”.

In 1990, 13 years after Voyager-1 left Earth on its mission to visit two of the gas giants and their moons of our solar system, Jupiter and Saturn, one last command was sent to the spacecraft as suggested by Carl Sagan who was then part of the Voyager-1‘s imaging team. That instruction was to turn back around and take one last photo of our solar system before continuing on its epic journey away from the Sun and the planets.

Near-Earth Asteroid 2012 DA14 Captured in a Gorgeous Time-lapse Video

On Friday, February 15th, 2013, near-Earth asteroid 2012 DA14 did a flyby of our planet — the closest approach ever of an object of its size (30 meters in diameter). Photographer Colin Legg of Western Australia decided to capture the close pass in a time-lapse video, and set up his cameras after midnight around 220 miles east of Perth.

He ended up capturing the amazing video above, while captures a shooting star burning a trail across the sky while DA14 slowly travels through the shot. The video also shows how much random stuff in the sky you can see if you have eyes/cameras sensitive enough to see it.

Amazing Animated GIFs Capture Nebulae in 3D Using Artificial Parallax

starparallax

Parallax 3D images use two photos captured from slightly different vantage point to create the appearance of depth. In astrophotography, however, the distance between human cameras and distance objects are so great that real parallax generally cannot be achieved.

Finnish astrophotographer J-P Metsavainio has developed a brilliant experimental technique that overcomes this (kinda): he converts astrophotographs into 3D volumetric models, and then uses those models to create dazzling 3D animations of nebulae.
