The universe is filled with flashy pyrotechnics, such as exploding stars or flaring black holes, which spew out unfathomable amounts of light and energy. These luminous objects have helped humans understand our cosmic surroundings for centuries, but a new study suggests they could have a more futuristic function—spaceship propulsion.
Given how much energy these sources pump out, it’s worth considering if any spacecraft could harness their power, argue the co-authors of a study that proposes such an approach: Manasvi Lingam, an astrobiologist at the Florida Institute of Technology, and Abraham Loeb, a theoretical physicist at Harvard University.

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.
