On April 25, 1990, the world—the Universe—changed.
That was the day the crew of STS-31 deployed the Hubble Space Telescope into orbit. This magnificent observatory has a special place in my heart. When it launched I was in graduate school in astronomy, and had just received my master’s degree. I was looking for Ph.D. research, and my adviser mentioned he was on a project to use Hubble to observe exploding stars … and now, 25 years later this week, Hubble is still going strong, doing astronomy.
And in my way, I am too.
I worked on Hubble one way or another for a decade, including being on a team that built one of the cameras that was installed on Hubble in 1997. I’ve written so much about Hubble over the past 2½ decades I don’t think there’s much more I can say about it. At the bottom of this post there are links to some of my favorite articles.
But I can still show you pictures.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
