How big is space? Interactive views of the universe in varying scales

We know space is big, but trying to understand how big is tricky. Say you stare up at the sky and identify stars and constellations in a virtual planetarium, you can't quite fathom how far away all those stars are (previously, twice). Even if you could change your point of view and zoom around in space to really see 100,000 nearby stars (autoplaying ambient music, and there are actually 119,617 stars mapped in 3D space), it's still difficult to get a sense of scale. There's this static image of various items mapped on a log scale from XKCD (previously), and an interactive horizontal journey down from the sun to the heliosphere with OMG Space (previously). You can get a bit more dynamic with this interactive Scale of the Universe webpage (also available in with some variants, if you want the sequel [ previously, twice], the swirly, gravity-optional version that takes some time to load, and the wrong version [previously]), but that's just for the scale of objects, not of space itself. If you want to get spaced out, imagine if If the Moon Were Only 1 Pixel, and travel from there (previously). This past March, BBC Future put out a really big infographic, which also takes a moment to load, but then you can see all sorts of things, from the surface of Earth out to the edge of our solar system.

Jewel Box Sun, seeing the sun through different lights

"This video of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, shows the wide range of wavelengths -- invisible to the naked eye -- that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors." And because it's NASA, you can download the video in various formats.

How Grandmother Triode Stole Binary from the Sun

a story of people[0xCF36] as told by shaman.Accumulator.Overflows(true)
In the beginning, there were too many numbers, and nobody could tell exactly what they were. Everybody was confused about what was big and what was small, because everything was kind of big, but also kind of small. Nobody knew anything for sure....

The Sun is a Mass of Cyclically Furious Gas

"The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity." Dr. Richard Fisher and other sun-gazing scientists recently discussed the upcoming peak in the 11-year sunspot cycle. Due to the ever-increasing humans' reliance on electrical systems, the storm could leave a multi-billion pound damage bill and "potentially devastating" problems for governments. Constant improvements in satellite designs have assisted in bracing for a solar superstorm, an effort that comes in part by studying the impacts records of activity from past peaks in solar storms. System limits are set based on significant solar storm-triggered events in the past, though the largest magnetic storm on record was before the modern understanding of solar events. The solar storm of 1859, also known as The Carrington Event, when "telegraphs ran on electric air," was experienced around the world. [more inside]
