This incredible footage from NASA’s Solar Dynamics Observatory (SDO) is about as we’re going to get to the Sun. The 59-minute time-lapse was stitched together from 133 days of extreme-ultraviolet imagery the probe captured of the Sun’s corona between August 12 and December 22, 2022.
Remember when you were a kid and burnt leaves with the sun and a magnifying glass? This is just like that, only bigger. For his graduation presentation, Jelle Seegers built a metal rig with a handmade fresnel lens on top that can concentrate solar rays tightly enough to smelt metal. It can achieve temperatures up to 1000ºC.
Replicating the sun’s brightness indoors isn’t easy to achieve. But if anyone can pull it off, it’s the guys from Corridor Crew. Though this time out, they didn’t rely on computers and visual effects and instead loaded up the studio with an insane amount of lighting gear. We’re amazed they didn’t light their test subject on fire.
Filmmaker Seán Doran processed about a week’s worth of data captured by NASA’s Solar Dynamics Observatory to create this awe-inspiring UHD video of the Sun’s activity. Max out the resolution, go full screen, dim the lights, and crank up the audio for a truly hypnotic journey to our Solar System’s number one life-giver.
Given that the Sun kicks out 35 octillion lumens of light, you’d think it might be hard to fake its brightness indoors. This video from DIY Perks shows us how it’s possible to create an incredibly convincing approximation of its parallel light rays using a high-powered LED, a parabolic dish, and a liquid diffuser.
The speed of light is pretty darned fast, but given just how far the Earth is away from the Sun, its light doesn’t get here instantly. It’s Okay to Be Smart teaches us how it’s not just a simple math equation, but complex astrophysics explain how sunlight is much older than you’d think.
Since 2010, NASA’s Solar Dynamics Observatory (SDO) has captured more than 425 million images of the Sun, with a still recorded once every 0.75 seconds. By grabbing one of these pictures from each hour, this time-lapse video condenses 10 years of footage down to just 61 minutes. Put on your sunglasses, sit back, and relax.
Solar flares and coronal mass ejections are frequent occurrences on the Sun. Some have been known to disrupt radio waves, but could they actually cause damage? Kurzgesagt stares directly into the Sun to educate us on solar storms, why they occur, and if a strong enough super storm could actually wipe out civilization.
NASA’s Solar Dynamics Observatory has been capturing high-def images of our sun for more than 7 years. Here’s footage captured by two of their systems – the larger one showing visible light, the smaller one showing extreme UV light, and the line graph displays sunspot activity.
Lots of us stayed outside to watch the big solar eclipse this week, but this isn’t the view any of us saw. Instead of looking up at the skies, the University of Wisconsin Madison time-lapsed weather satellite imagery to track the shadow of the moon as it crossed the US.
