The Milky Way Galaxy’s Largest Globular Cluster #SpaceSaturday
Some terms for space objects have a certain poetic majesty. Nebula. Quasar. Dark matter. Then there’s “globular cluster,” which doesn’t conjure as much mystery for many folks. But globular clusters are awesome. Here’s more on the galaxy’s largest globular cluster, from Astronomy Now:
Peering into the densely packed core of Omega Centauri, the Hubble Space Telescope provides a spell-binding look at one of the galaxy’s largest globular clusters, a swarm of more than two million suns some 17,000 light years from Earth. Easily visible to the unaided eye in the southern constellation Centaurus, Omega Centauri may harbour a black hole with about 40,000 times the mass of the Sun based on the higher-then-expected velocities of stars near its core. Astronomers have long theorised such intermediate-mass black holes may be a common feature of globular clusters, providing the gravitational glue holding the huge assemblies together.

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.
