This Asus PC case monitors your dust filter so you don’t have to
Traditionally, one would have to periodically check the status of the dust filtering on a PC case, but that’s not the case (pun intended!) with the Asus ProArt PA602. This chassis has a fancy infrared (IR) sensor behind the front-facing dust filter. ...continues
When allergy season hits, many blame their reactions on the local flora in the spring. However, African Saharan-Sahelian #dustplumes, large enough to register on weather radar, travel around the globe every summer, bringing their own form of #airpollution.
This is a work-in-progress image of the Boogeyman Nebula. Located off Orion's left side, this area is rich with red hydrogen alpha gas and dark dust. This image contains about 6 hours of Ha data + 11 hours of broadband data, but it could use quite a bit more. Orion is setting earlier and earlier and the nights are getting shorter, so hopefully I can grab enough data before it's gone for the season.
Dust: The Modern World in a Trillion Particles by Jay Owens
This is a book on humanity and Earth and what we’ve done to it. Dust moves from the suburbs of a thirsty Los Angeles to Oklahoma and its Dust Bowl migrants, and the desert Southwest where nuclear testing created radioactive fallout that spread across America.
Hmm, will likely be wiping down walls and everything else for awhile, not to mention HEPA vacuuming the (disaster remodeled) house, I suspect drywall dust will be a major contributor to PM2.5. Might even do a wet mop of the floors before they start re-flooring... #dust#remodeling
The dusty reflection nebula in this image is Messier 78, sometimes called "Casper the Friendly Ghost Nebula." The red wall on the left side is part of Barnard's Loop, which is a huge arc of bright red hydrogen gas. For this image, I combined 21 hours of broadband data with 9 hours of narrowband data to pop out the red color.
Get a preview of where we'll be going to collect some #dust samples in this series of videos from 2023 where we traveled to our array of long term passive collectors stationed in the #Southwest#UnitedStates.
The Seahorse Nebula, also known as Barnard 150, is a swirly dust cloud in a dense starfield. This is my deepest image to date with 31.5 hours of integration time. It's coming along, but this is one of those objects that could use as much integration time as you can throw at it. Next time around, I'll try a long run with the Optolong L-Quad light pollution filter.
In the latest episode of "Nature hits the books", writer and researcher Jay Owens joins us to discuss her book Dust: The Modern World in a Trillion Particles.
Much like #dust itself, Jay’s book travels the globe, looking at the impacts that these microscopic #particles are having on the world, our health and #environment, as well as exploring the role that humanity has played in creating them.
The NASA/ESA Hubble Space Telescope captured this image of NGC 7049 in the constellation of Indus, in the southern sky. The dust lanes, which appear as a lacy web, are backlit by the millions of stars in the galaxy's halo.
Featuring an artist’s impression of a massive young star in the process of forming, discovered in our nearest neighbouring galaxy, the Large Magellanic Cloud.
