Southern Observatory (ESO) astronomers reported the closest black hole to Earth, located just 1000 light-years away in the HR 6819 system. But the results of their study were contested by other researchers, including by an international team based at KU Leuven, Belgium. In a paper published today, these two teams have united to report that there is in fact no black hole in HR 6819, which is instead a “vampire” two-star system in a rare and short-lived stage of its evolution.</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/web/20220303164848/https://www.eso.org/public/news/eso2203/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20220303164848im_/https://cdn.eso.org/images/thumb350x/eso2203a.jpg"> </div> <div class="news-description"> <div class="news-id">eso2203 — Science Release</div> <div class="news-title">Supermassive black hole caught hiding in a ring of cosmic dust</div> <div class="news-teaser"><strong>16 February 2022</strong>: The European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI) has observed a cloud of cosmic dust at the centre of the galaxy Messier 77 that is hiding a supermassive black hole.

But no need to worry, this iconic constellation is neither exploding nor burning.

Not many were known until now, but a team of astronomers, using data from several European Southern Observatory (ESO) telescopes and other facilities, have just discovered at least 70 new rogue planets in our galaxy.
