The Hubble Space Telescope: The camera that changed the universe

NewImage

Ethan Siegel has a great (and extensive) post over on Medium about the history of the Hubble Space Telescope. It’s definitely worth a read. Fun fact I learned from the piece: There are over 100,000,000,000 confirmed galaxies in the universe (confirmed because of Hubble)! Makes you feel small doesn’t it? Also, look at those photos! Beautiful.

The Hubble Space Telescope took its first images in 1990, but it was really starting in 1993 — after the first servicing mission — that the science really started to skyrocket.

That, of course and the awe that it brought us back. Not only did we fix the initial problem of the primary mirror and spherical aberration, but we were able to upgrade the main camera.

What we installed — the Wide Field Planetary Camera 2 (WFPC2) — was without a doubt the camera that changed the Universe. Just looking at what the difference was before and after the first servicing mission!

From 1993 to 2009, WFPC2 was the main, workhorse camera on the Hubble Space Telescope, and took a myriad of iconic images over its lifetime. But five of them stand out, in particular, as images that changed our Universe forever.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
