Undiscovered planets may soon be revealed, thanks to a technological breakthrough by scientists.
Physicists based at Heriot-Watt University in Edinburgh and Cambridge University have developed a form of astrocomb – a laser system that allows astronomers to observe tiny changes in the colour of starlight, revealing hidden planets in the process.
Researchers say the technology could also improve understanding of how the universe naturally expands.
While astrocombs have been used by scientists studying the cosmos for several years, they were previously limited mainly to the green-red part of the colour spectrum.
However, the breakthrough will allow scientists to utilise the ultraviolet to blue-green part of the spectrum, which means they will be able to discover even more secrets hidden in space.
