Zodiacal Road

Explanation:
What's that strange light down the road? Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner Solar System appears prominently just after sunset -- or just before sunrise -- and is called zodiacal light. Although the origin of this dust is still being researched, a leading hypothesis holds that zodiacal dust originates mostly from faint Jupiter-family comets and slowly spirals into the Sun. Recent analysis of dust emitted by Comet 67P, visited by ESA's robotic Rosetta spacecraft, bolsters this hypothesis. Pictured when climbing a road up to Teide National Park in the Canary Islands of Spain, a bright triangle of zodiacal light appeared in the distance soon after sunset. Captured on June 21, 2019, the scene includes bright Regulus, the alpha star of the constellation Leo, standing above center toward the left. The Beehive Star Cluster (M44) can be spotted below center, closer to the horizon and also immersed in the zodiacal glow.

Presumed feedback process that sounds interesting

"Global dust mass loading has increased 55 ± 30% since pre-industrial times, driven largely by increases in dust from Asia and North Africa"

In a new study

"The new findings establish a measurable link between dust in the air and the abundance of ice on the tops of clouds"

NatureMineral dust aerosol impacts on global climate and climate change - Nature Reviews Earth & EnvironmentDust influences the global energy budget through various Earth system interactions. This Review outlines these interactions, revealing a total radiative effect of −0.2 ± 0.5 W m−2, which, alongside 55 ± 30% historical increases in dust, have contributed a radiative forcing of −0.07 ± 0.18 W m−2.

Dust and vultures take flight - The wind really picked up the evening of April 1st, causing the dry, red soil to take flight. I was out on a several-mile hike, and this dust storm had me crying mud and chewing sand, but at least the lighting was cool! Several turkey vultures were flying through the dusty canyon, which I thought looked pretty neat. Thank goodness for weather-sealed gear. I really put weather sealing to the test! - Palo Duro Canyon State Park, Texas, USA #Texas #TexasPanhandle #bird #vulture #canyon #paloduro #palodurocanyon #hiking #dust #wind #landscape #nature #weather #Fujifilm

Anyone know about this app, called Dust? (Note: I don't think it's the secure messaging app). It's apparently for regional burns (mini-Burning Man events). A burn I'm attending is going to do all their organizing, messaging, mapping, etc. using the Dust app.

I fucking hate apps. I mean, some are okay. I hate everything in the world shoving an app at you, mostly because nearly every such app requires a significant chunk of personal data, then needs permissions it shouldn't have, and almost certainly resells my data or keeps it just in case the company needs extra cash.

So... how do I find this stuff out? It's not a major app; maybe a few thousand or tens of thousands of people ever use it, so I'm not finding any info about it by online searching. Admittedly, my google-fu (well, ddg-fu) might be lacking.

If you have any info about how predatory or chill this app is, or hints where I can find such info, I hope you'll share.

Before I do more work at the tail end of the glider's fuselage (install the tail water ballast tank), I want to get most of the debris out of the tail boom. When I rotate the fuselage, it sounds like a pair of maracas.

I have an access hole in the aft battery box bulkhead, so I connected the shop vac hose to the exhaust side...to get all the air moving out of the tail boom at a good clip, then inserted the compressor hose at 100PSI to knock debris loose and give it a kick.

As northern states were dealing w/ #smoke, a large plume of #Saharan #dust is expected to spread over #GulfCoast states through Thurs. Chenard said the dust had reached parts of #Florida by Wed morning, & was expected to intensify.

“The highest concentrations of the dust is definitely going to be through today & tonight,” he said. “But there will be some at least lower concentrations that linger over Florida, probably into the weekend.”

Canadian #wildfire #smoke causes 'very #unhealthy' conditions in American #Midwest & reaches #Europe

Wildfire smoke from #Canada & plumes of
desert #dust from the #Sahara are smothering large portions of the #UnitedStates, creating hazy skies & hazardous #AirQuality from the Midwest to the East Coast.

Officials said that those more sensitive to #air #pollution should limit going outdoors & watch for #respiratory symptoms through Thursday.
