November 29, 20233min readA solar outburst shoots charged particles into space—and toward EarthBy Meghan BartelsA filament erupted from the sun on Nov. 27, 2023, and left a “canyon of fire” visible in the bottom right of this view. A long filament of roiling plasma arcing over the sun’s surface snapped this week, leaving behind a scalding scar that has been dubbed a “canyon of fire.” It also spat a burst of solar plasma into space. There’s a chance this solar outburst and several that followed it could trigger minor…

The Earth cannot catch a break from the Sun's wrath. It has been hours since the Earth has passed the coronal mass ejection (CME) cloud that sideswiped our planet, creating a very weak aurora display, and the Sun is preparing another onslaught. An astronomer has observed a magnetic filament near the equator of the Sun which is bustling with a huge amount of magnetic field lines. This means it can soon erupt and send another wave of solar storm towards our planet. Check the details.The development was captured by Dr.…

By now you’ve almost certainly heard the whole spiel about switching your lights over to LED bulbs, but what about the benefits of smart home lighting? Philips Hue’s filament bulbs accomplish both, delivering LED lighting with the added perk of Siri, Alexa, and Assistant support all rolled into a stylish package. Not to mention, you can score one of the best prices yet on a 2-pack of the old school Edison-style bulbs right now, too. We also have a wide selection of Tesla and e-bike discounts in today’s…

Solar winds from the snapping of a gigantic "canyon of fire" filament on the Sun are set to slam into the Earth today (20 July) or tomorrow (21 July), triggering a weak G1 geomagnetic storm.  Sun watchers first spotted solar filaments as dark, thread-like lines against the Sun's bright background on 12 July, according to SpaceWeather.com.Then, on 15 July, a filament that had snaked its way down our star's northern hemisphere erupted, carving out a roughly 238,880-mile-long (384,400 kilometers) and 12,400-mile-deep…

I was particularly curious about how the bottles are cut. Discord user @Alextrical told me that, "It's the bearings that cut the bottle, the edges slide over each other and shear the plastic similar to scissors." So this would be safe in a community environment, and there are no issues involved in sharpening or replacing blades. It should be noted that Cheng isn't the first to build a PET plastic bottle to filament recycling device. He cites as inspiration Joshua Taylor at recreator3d.com, which has…
