Some of the health risks of inhaling fine and ultrafine pollutant particles are well-established, such as asthma, lung cancer, and, most recently, heart disease. But a growing body of evidence suggests that such exposure can also harm the brain, accelerating cognitive aging, and may even increase risk of Alzheimer’s disease and other forms of dementia.

Linda imagem.
A stereo image of Jupiter’s atmosphere, derived from data collected by the Juno spacecraft during perijove 3. These images, taken at different point in the orbit, can be combined to reveal the 3D structure and relief of clouds in the southern atmosphere. To see the image in 3D, relax the eyes until the white circles overlap, then look at the image. Alternatively the image can be viewed with Google Cardboard or another VR device.

Fantástico!!
What’s that green streak in front of the Andromeda galaxy? A meteor. While photographing the Andromeda galaxy last Friday, near the peak of the Perseid Meteor Shower, a sand-sized rock from deep space crossed right in front of our Milky Way Galaxy’s far-distant companion. The small meteor took only a fraction of a second to pass through this 10-degree field. The meteor flared several times while braking violently upon entering Earth’s atmosphere. The green color was created, at least in part, by the meteor’s gas glowing as it vaporized. Although the exposure was timed to catch a Perseids meteor, the orientation of the imaged streak seems a better match to a meteor from the Southern Delta Aquariids, a meteor shower that peaked a few weeks earlier

Do not go where the path may lead, go instead where there is no path and leave a trail. —Ralph Waldo Emerson
Como as pessoas a nossa volta nos marcam. Interessante o uso de cores, uma vez que a energia que nos envolve tem amplitudes diferentes, portanto podemos representá-la pelo expectro de cores.
