A new visualisation from NASA’s Goddard Space Flight Center illustrates how a black hole’s concentrated gravity warps the space surrounding it much like a carnival mirror distorts reflections.
Seen from an edge-on perspective, the accretion disc has a distinctly asymmetric appearance, with gas on the left side moving toward the viewer at such high speeds that radiation is given a relativistic boost in brightness. Gas on the right side that’s moving away from the viewer is slightly dimmer. The asymmetry vanishes when the disc is viewed face on because none of the material is moving along the viewer’s line of sight.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
