Clouds based on outgoing longwave radiation data from NASA (sped up greatly). Data is low resolution so I added noise to break it up, hard to capture the varied look of the real thing
Zodiacal Light at orbital sunrise. This reel shows a sunrise from @ISS where the interplanetary dust in our solar system is seen as the zodiacal cloud.
Star trail photograph from my previous mission to the @iss. This is a 28 minute time exposure composed of individual 30 second shots taken during orbital night. I call it "Purple Haze."
#astrophotography can bring out the color in the universe like little else!
Curious about @NASAWebb’s mission to #UnfoldTheUniverse? Interested in how it will study distant worlds?
Join former Webb Project Scientist Dr. Alex Lockwood on our next episode of #AskAstrobio! Set a reminder to watch & ask questions – Aug. 25 at 2pm ET: go.nasa.gov/3CwHsBz
ALT A wide field view showcases Jupiter in the upper right quadrant. The planet’s swirling horizontal stripes are rendered in blues, browns, and cream. Electric blue auroras glow above Jupiter’s north and south poles. A white glow emanates out from the auroras. Along the planet’s equator, rings glow in a faint white. These rings are one million times fainter than the planet itself! At the far left edge of the rings, a moon appears as a tiny white dot. Slightly further to the left, another moon glows with tiny white diffraction spikes. The rest of the image is the blackness of space, with faintly glowing white galaxies in the distance.
I ended up re-implementing gmtime (and mktime) because Microsoft's implementation starts failing around 1000 years into the future. There are more corner cases than I would have expected, but on the upside I now know everything about the Gregorian calendar...
Working on orbital rings and space elevators. The power satellites around Titan are all sending each other power which is not really ideal but looks neat.
An object is in orbit when the acceleration due to gravity and the acceleration due to circular rotation perfectly cancel.
If Earth didn't rotate, we would feel about 3% heavier.
If Earth rotated every 84 minutes, we would be weightless.
The counterweight on the tip of a 100,000 km long space elevator would experience about 5% as much weight as Earth, probably not enough for people to live in long term.
I've seen things you people wouldn't believe... Shadow acne off the shoulder of Jupiter... I watched Z-buffer failures glitter in the dark near the Marduk Condenser.
I usually enjoy smugly telling Unity devs that custom engines are better and they should really understand frustum culling anyway, but this latest round of Unity woes has me just feeling sad that a few megalomaniac capitalists can pointlessly destroy so much real human value
ALT This image of Stephan’s Quintet, a visual grouping of five galaxies, is contains over 150 million pixels and is constructed from almost 1,000 separate image files. Sparkling clusters of millions of young stars and starburst regions of fresh star birth grace the image. Sweeping tails of gas, dust and stars are being pulled from several of the galaxies due to gravitational interactions. Most dramatically, Webb captures huge shock waves as one of the galaxies, NGC 7318B, smashes through the cluster. Credits: NASA, ESA, CSA, and STScI
ALT This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth. Credits: NASA, ESA, CSA, and STScI
ALT Two cameras aboard Webb captured the latest image of this planetary nebula, cataloged as NGC 3132, and known informally as the Southern Ring Nebula. Credits: NASA, ESA, CSA, and STScI
ALT NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date, known as Webb’s First Deep Field, this image shows galaxy cluster SMACS 0723. Credits: NASA, ESA, CSA, and STScI
👀 Sneak a peek at the deepest & sharpest infrared image of the early universe ever taken — all in a day’s work for the Webb telescope. (Literally, capturing it took less than a day!) This is Webb’s first image released as we begin to #UnfoldTheUniverse: nasa.gov/webbfirstimages/
ALT The background of space is black. Thousands of galaxies appear all across the view. Their shapes and colors vary. Some are various shades of orange, others are white. Most stars appear blue, and are sometimes as large as more distant galaxies that appear next to them. A very bright star is just above and left of center. It has eight bright blue, long diffraction spikes. Between 4 o’clock and 6 o’clock in its spikes are several very bright galaxies. A group of three are in the middle, and two are closer to 4 o’clock. These galaxies are part of the galaxy cluster SMACS 0723, and they are warping the appearances of galaxies seen around them. Long orange arcs appear at left and right toward the center.
