Aerosols are tiny solid or liquid particles in our atmosphere like dust, sulfates from pollution or volcanoes, wildfire smoke, and more. NASA’s GEOS model shows how these particles can affect the air we breathe—even from far away.

Tiny particles floating in our air. This visualization shows how tiny particles called aerosols move through Earth's atmosphere from August 1 to September 14, 2024, using NASA's Goddard Earth Observing System (GEOS) model. These particles, which include sea salt, dust, smoke, and sulfates, can travel thousands of miles and affect air quality and visibility far from their original sources. By tracking these movements, NASA helps communities prepare for changes in air quality and visibility while advancing our understanding of Earth's complex atmospheric system.

Intense heat from this large wildfire in Broward County, Florida is rising so rapidly that it’s cooling and condensing onto smoke particles, creating these towering pyrocumulus clouds. ☁️🔥Ash was even found on cars in Pembroke Pines. More than 11,000 acres burned so far. #FLwx

Microplastics have already been detected in the air and in the ocean. New research shows that plastic particles affect the distribution of water in clouds and the ocean’s heat conductivity. How could these findings help to adjust our climate models? Learn more via the link.

Respiratory viruses like COVID and the flu can be spread by coughing, sneezing, talking, singing or even just by breathing. When this happens, microscopic airborne particles called aerosols pass through the air. If you inhale an infectious particle, you could become unwell.

This animation shows hourly measurements of Particulate Matter 10 micrometres or less in diameter (PM10) across the Po Valley from 1 January to 31 January 2024. The data was obtained from Copernicus ECMWF reanalysis modelled data. PM10 plays a pivotal role in the air quality dynamics of the Po Valley. Comprising various particles like dust, pollen and combustion byproducts, PM10 is inhalable and can impact respiratory health.

These brilliant young Londoners in Lambeth are building air filters to protect their classroom from air pollution. All Londoners have the right to breathe clean air. We can’t leave the responsibility of cleaning up our toxic air with children.

If you do not use an air filter, your lungs will become the filter. (41 seconds) The New World Order is intoxicating the atmosphere with nanotech fog, chemtrails, VOCs. Breathe Clean. Make your living space free of toxins. AirDoctor: Stop Mold, Dust, Viruses, Pollen, Mites, Chemtrail Debris and More in your Own Home! 📲 HEPA and charcoal filters for your home and work. Gift yourself & loved ones with Clean Air! Indoor Air Pollution has been calculated as being 5-10 times worse than outdoor air pollution. Capture the pollution by filtering it before it reaches your lungs. Air Doctor captures: mold, spores, pollen, viral debris, dander and more. An essential component of a healthy lifestyle in a toxic world. Years ago, my family and I invested in AirDoctor purifiers for every room in our home. They are nothing short of amazing! Our home is filled with clean, fresh air, even when the wildfire smoke outside was suffocating. We also use a wood burning stove in the home during the winter; the Air Doctor captures any smoke that escapes into the home from our stove improving our quality of life.

What if point particles in Physics are just an illusion? Branes are higher-dimensional objects in String Theory that generalize the idea of a point particle. Instead of everything being just 0-dimensional points or 1-dimensional strings, a Brane can have 2, 3 or more spatial dimensions Open strings can end on Branes, which means Branes act like boundaries for string motion. In many models, what we call particles are simply vibration modes of strings attached to these Branes, and force can be understood as strings stretching between them.

Health concerns are growing as wildfire smoke from Canada is blanketing large parts of the U.S. That's led to unsafe air-quality conditions for tens of millions of Americans, from the Upper Midwest to the Mid-Atlantic and New England. Detroit was among the most polluted cities in the world on Friday, as thick smoke blotted out the skyline and obscured the sun. The haze also settled over Washington, D.C., carrying fine particles that can be more toxic than typical air pollution. Across a wide stretch of the country, from Chicago to Manhattan, people wore masks and limited their time outdoors. The wildfire smoke will linger across the Northeast for much of the weekend, but forecasters expect the skies to clear by Sunday afternoon in New Jersey, in time for the World Cup final between Spain and Argentina.

"You got to stop these fires from coming in and poisoning our air!": Trump says he has a "good relationship" with Carney, but suggests Canada may be forced to pay damages or face additional tariffs due to wildfire smoke entering the US.

NASA satellites and computers have provided us with these mesmerizing swirls that cover our planet—but this isn’t star stuff. Each color represents a different aerosol that was floating in the atmosphere above our heads from 1 August to 14 September 2024. Depicting aerosols in this way helps us understand how far-flung corners of the globe are connected via our shared atmosphere. Learn more in #ScienceAdviser—our free daily newsletter:

Coming back to Delhi from Wayanad where the air is beautiful and the AQI is 35, was like entering a gas chamber. The blanket of smog is even more shocking when seen from the air. Delhi’s pollution gets worse every year. We really should put our heads together and find a solution for cleaner air. It’s beyond this party or that, it’s practically impossible to breathe especially for kids, elders and those with respiratory issues. We just have to do something about it.

Why do meteors seem to come from one point in the sky? 🌠 During a meteor shower, Earth passes through a stream of tiny particles left behind by a comet or asteroid. These particles enter our atmosphere on nearly parallel paths. But from our point of view on the ground, those paths appear to spread out from a single point in the sky. This point is called the radiant. It’s the same perspective effect you see with railroad tracks: the tracks are parallel, but they seem to meet in the distance. So meteors don’t actually fly out of one spot — they only appear that way from Earth. ✨ That’s why meteor showers are named after the constellation where their radiant appears: the Perseids from Perseus, the Geminids from Gemini, and so on. #meteorshower #astronomy #didyouknow #meteors #starwalk

According to Dhruv Rathee and his group of liberals who worry about air pollution only during Diwali 😂🤡, what about the major causes of air pollution such as vehicle emissions from cars and trucks, industrial smoke from factories, burning of fossil fuels like coal and oil, deforestation which reduces carbon absorption, and agricultural activities involving fertilizers and pesticides? It’s important to recognize that these everyday sources contribute far more to air pollution than the occasional firecrackers during festivals. #diwali #diwali2025
