New Images of Distant Galactic Space Dust #SpaceSaturday
The beauty of the dust in space, brought to you by the Herschel Space Observatory. Here’s more from Science Alert:
…But stars are far from the only ingredient that makes up a galaxy. Think of them as the chunks of vegetables in the galactic soup.The broth, then, in which [stars] float, is the intergalactic medium – not empty space but filled with often tenuous, sometimes dense clouds of dust and gas that drift between the stars. Because stars are so much brighter, the dust is usually second fiddle; but that dust, from which stars are born, to which stars return, can tell us a lot about the structure and activity within a galaxy.
Now, four new images have been released, showing the distribution of dust in four of the galaxies that are closest to the Milky Way: the Large and Small Magellanic Clouds, dwarf galaxies orbiting our own; the Andromeda galaxy, a large spiral galaxy at a distance of 2.5 million light-years; and the Triangulum galaxy, a spiral galaxy 2.73 million light-years away.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
