A new material inspired by a chameleon serves to keep the heat during cold days and lower temperatures during hot days.
For the first time, James Webb Space Telescope (JWST) measures the temperature of an exoplanet of star system TRAPPIST-1, and it’s 230ºC (446ºF).
The Solar Orbiter probe of ESA and NASA, obtained impressive images of Sun’s south pole during its perihelion, the closest distance from Sun.
In addition to the turbofan, exist other jet engines. In this post it’s shown the operation and applications on aviation of turbojet, turboprop, and turboshaft.
The James Webb Space Telescope (JWST), launched on Christmas last year, arrived at Lagrange point L2 of Earth-Sun system.
The space telescope James Webb, the Hubble’s successor, will be launched soon and make observations at 13.8 billion light-years.
This post’s subject is the turbofan jet engine. It’s used in every commercial airplane due to high thrust and for being the most efficient and silent type.
This post is the second part about thermoelectricity. Thomson effect is a reversible thermoelectric phenomenon and related to Seebeck and Peltier effects.
The Seebeck and Peltier effects are thermoelectric phenomena that explain the operation of thermocouples, temperature sensors with 2 different materials.
A new formula for white paint got a reflectivity record, allowing to save energy with air conditioner and improve thermal isolation.
