Web23 hours ago · The Virgo Cluster of galaxies, with the giant elliptical galaxy M87 at the upper left. Despite its seeming symmetry, a UC Berkeley study shows that M87’s 3D shape is very asymmetric. This determination helps refine estimates of the mass of the supermassive black hole at the galaxy’s center. (Image credit: Fernando Pena) Ma, UC Berkeley ... WebTo create a DHT11/DHT22 web server with ESP32/ESP8266 using MicroPython, we need to create two MicroPython files such as boot.py and main.py. The boot.py file is a microPython script which runs once ESP32/ESP8266 boots. The main.py file contains HTML document, socket server to listen to socket client requests, script to send and receive … flower with yellow stick in center
