The space scientists across the world are trying hard to find out Earth-like exoplanets in alien solar systems that supports life just like ours. But they believe the grit and space dust produced from asteroid collisions and comet remnants could serve as a stumbling element in making such distinguishable discoveries.
The astronomers say exozodiacal light, which are reflected from space dust and grime of asteroids and comets, prevents them from detecting small Earth-like exoplanets, their solar systems and their alien suns.
The Very Large Telescope Interferometer (VLTI), which is located in Chile, first detected the exozodiacal light that was coming from far away galaxies.
The main goal of VLTI is to spot and study 92 local star systems.
Zodiacal light can be usually observed before sunrise or immediately after sunset. They are also known as false dawn and false dusk. Hence they are often mistaken as the rising or setting sun.
These zodiacal lights are commonly seen on the Earth in those areas that have completely dark skies. They emerge as a white glow originating from the horizon around the sun.
Scientists found that while combining images from four telescopes with the help of the VLTI interferometer, this system helped them studying it in much detail.
Olivier Absil, study co-author and researcher at the University of Liège, said that this stardust light could help in detecting alien planets at higher rate even if it contains fainter dust that are undetectable in the survey.
The results of the study were detailed on website of the European Organisation for Astronomical Research in the Southern Hemisphere.
