Balloon Mounted Telescope Captures Tarantula Nebula in First Research Images #SpaceSaturday
As it turns out, balloons really are used as observation devices. Observation of deep space, that is. Here’s more from NASA:
The advantage of balloon-based versus space telescopes is the reduced cost of not having to launch a large telescope on a rocket. A super pressure balloon can circumnavigate the globe for up to 100 days to gather scientific data. The balloon also floats at an altitude above most of the Earth’s atmosphere, making it suitable for many astronomical observations.
The SuperBIT telescope captures images of galaxies in the visible-to-near ultraviolet light spectrum, which is within the Hubble Space Telescope’s capabilities, but with a wider field of view. The goal of the mission is to map dark matter around galaxy clusters by measuring the way these massive objects warp the space around them, also called “weak gravitational lensing.”
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
