Dark galaxies are small, gas-rich galaxies from the early universe that are believed to be the building blocks of today's bright, star-filled galaxies, said the ESO, an intergovernmental organisation supported by 15 countries.
"Our approach to the problem of detecting a dark galaxy was simply to shine a bright light on it," researcher Simon Lilly said in the release.
"With this study, we've made a crucial step towards revealing and understanding the obscure early stages of galaxy formation and how galaxies acquired their gas," added his colleague, Sebastiano Cantalupo.
The ESO is supported by Austria, Belgium, Brazil, Britain, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden and Switzerland.
