Three Astronomers on the James Webb Space Telescope #SpaceSaturday
We’ve all seen the images that the James Webb Space Telescope. As it turns out, the big, amazing, astonishing, detailed images are only the beginning. They may not even be the main course. Here’s more from Dan Coe of AURA/STScI for the European Space Agency and the Johns Hopkins University, Tiger Hsiao of the Johns Hopkins University, and Rebecca Larson of the University of Texas at Austin, via Phys.Org:
Dan Coe: “I discovered this galaxy MACS0647-JD 10 years ago with the Hubble Space Telescope. At the time, I’d never worked on high redshift galaxies, and then I found this one that was potentially the most distant at redshift 11, about 97 percent of the way back to the big bang.”
“With Hubble, it was just this pale, red dot. We could tell it was really small, just a tiny galaxy in the first 400 million years of the universe. Now we look with Webb, and we’re able to resolve TWO objects! We’re actively discussing whether these are two galaxies or two clumps of stars within a galaxy. We don’t know, but these are the questions that Webb is designed to help us answer.”
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.
