Astronomers are searching for signs of extraterrestrial life forms using all the tools they have. The Earth’s neighboring planets, as well as comets and asteroids are extensively researched with the help of orbiters and rovers. But finding habitable planets outside the Solar System is the astronomical Holy Grail. Unfortunately, a team of scientists found a characteristic that may hinder such a groundbreaking discovery.
The Very Large Telescope Interferometer (VLTI) is operated by the European Southern Observatory and sits at more than 8,500 feet high in Chile. The international team of researchers used all the four telescopes and pushed them to their limits to look at 92 stars.
