Citizen scientists find a failed star in the Sun’s neighborhood

Citizen scientists may not have the time and equipment of their pro counterparts, but their dedication can sometimes lead to discoveries that would otherwise be impractical. Case in point: a NASA-backed citizen science initiative, Backyard Worlds: Planet 9, has found a brown dwarf(effectively, a failed star) relatively close to the Sun at 110 light years away. Rosa Castro and three other amateur observers combed through a “flipbook” of images from the Wide-field Infrared Survey Explorer to spot the dwarf as it traversed through space. The discovery is notable for a few reasons, and not just because dedicated astronomers didn’t catch it.

How to Fast-Charge Your Supercapacitor

Sponsored by Maxim Integrated

Supercapacitors (or ultracapacitors) are suited for short charge and discharge cycles. They require high currents for fast charge as well as a high voltage with a high number in series as shown in two usage cases: an automatic pallet shuttle and a fail-safe backup system. In these and many other cases, the fast charge is provided by a flexible, high-efficiency, high-voltage, and high-current charger based on a synchronous, step-down, supercapacitor charger controller.

UWB: Because Location Matters

Sponsored by Mouser Electronics and Qorvo

While technologies like GPS, WiFi, and Bluetooth all offer various types of location services, none of them are well-suited to providing accurate, indoor/outdoor, low-power, real-time, 3D location data for edge and endpoint devices. In this episode of Chalk Talk, Amelia Dalton chats with Mickael Viot from Qorvo about ultra-wideband (UWB) technology, and how it can revolutionize a wide range of applications.
