Scientists at Heriot-Watt University in Edinburgh and Cambridge University have developed a groundbreaking technology that could potentially lead to the discovery of new Earth-like planets. The development of an astrocomb by physicists now allows for the analysis of the blue-green light emitted by stars. These astrocombs are able to detect slight variations in a star’s light caused by orbiting exoplanets, which are planets outside of our solar system.

This breakthrough expands the possibilities within the field of space exploration and allows researchers to examine shorter wavelength light in order to uncover previously unknown secrets of the universe. Dr. Samantha Thompson from Cambridge University expressed excitement over this new technology, stating that it could allow for the study of smaller planets with longer orbits, with the goal being to discover the first Earth-like planet orbiting around a nearby sun-like star.

The technology is currently being developed for the Extremely Large Telescope (ELT) being constructed in Chile’s Atacama Desert. This telescope will have a 39-meter primary mirror, making it the largest visible and infrared light telescope in the world. The UK team involved in this project will also be working on implementing astrocombs for telescopes in South Africa and the Canary Islands. The potential for this new technology to lead to significant discoveries in space exploration is an exciting prospect for researchers and scientists alike.
