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

Outer kimono (uchikake), satin silk with appliqué and embroidery, 1870–90. Scenes from two well-known plays feature. The garment may have been worn by a Kabuki actor, but decorative themes on stage costumes were not usually so literal and may instead have belonged to a high-ranking courtesan. The enjoyments of the theatre and the brothel were closely linked during the Edo period (1615 – 1868), being at the heart of the ‘floating world’ of transient excitement and pleasure.
Over geological timescales – on the order of millions of years – even hard substances like rock can flow like a fluid. Heat from the Earth’s core drives convection inside our mantle, and that fluid motion ultimately drives the plate tectonics we experience here at the surface. But most other planetary bodies, including those with mantle convection similar to ours, don’t have a surface that shifts like our tectonic plates. Mars and Venus, for example, have solid, unmoving surfaces. The images above provide a peek at what goes on beneath. The upper image shows a simulation of mantle convection inside Mars over millions of years. The lower image is a timelapse of dye convecting through a layer of glucose syrup being heated from below. Notice how both examples show evidence of convective cells and plumes that help circulate warm fluid up and colder fluid downward. (Image credit: Mars simulation - C. Hüttig et al, source; N.

Zoom into the Bloodstream by Linda Nye
This amazing visualization of human circulation takes you from the heart, to the smallest arteries, to single oxygen atoms.
How many of you can name all of the scientific components that you see here? Hint: the big yellow ball with purple on it in the back is a cholesterol particle
P.S. If you’re a nerd like me and like reading journal articles, check this one by Linda Nye on biomedical visualization out : (x)
