This project aims to guide individuals in constructing a radio telescope at home or in a classroom for under $200. The tutorials provided offer step-by-step instructions on building the telescope using easily accessible materials like cardboard. Once built, the telescope can be used to observe and analyze the spiral structure of the Milky Way galaxy. The project includes sections on science background, telescope construction, observing, data analysis, and additional resources for beginners in radio astronomy, electronics, and programming. For those interested in contributing or accessing the code base, a link to the Github repository is provided. The project encourages questions, suggestions, and offers more information about the team on the About page.

A black hole of inexplicable mass
The James Webb Space Telescope observed galaxy J1120+0641, revealing a mature quasar with a billion solar mass black hole at cosmic dawn. This challenges theories on black hole growth, suggesting they may start with substantial masses. The study sheds light on early black hole development, showing unexpected normalcy in early quasars, challenging assumptions on their evolution.

5 commentsI will say that gathering data that is unmistakably not noise, as well as meaningfully analyzing it, is difficult for would-be amateur radio astronomers (in my brief experience as a high school student aspiring to be one). I'd really like to see a version of this project that doesn't stop at just detection / ostensibly mapping Milky Way spectra, but given its limitations, I'm not sure if it's possible.
