This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core.</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/20210417202423/https://www.eso.org/public/news/eso2104/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20210417202423im_/https://cdn.eso.org/images/thumb350x/eso2104a.jpg"> </div> <div class="news-description"> <div class="news-id">eso2104 — Science Release</div> <div class="news-title">Powerful stratospheric winds measured on Jupiter for the first time</div> <div class="news-teaser"><strong>18 March 2021</strong>: Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, a team of astronomers have directly measured winds in Jupiter’s middle atmosphere for the first time. By analysing the aftermath of a comet collision from the 1990s, the researchers have revealed incredibly powerful winds, with speeds of up to 1450 kilometres an hour, near Jupiter’s poles.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have seen a galaxy ejecting nearly half of its star-forming gas. This ejection is happening at a startling rate, equivalent to 10 000 Suns-worth of gas a year — the galaxy is rapidly losing its fuel to make new stars. The team believes that this spectacular event was triggered by a collision with another galaxy, which could lead astronomers to rethink how galaxies stop bringing new stars to life.</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/20210417202423/https://www.eso.org/public/news/eso2019/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://web.archive.org/web/20210417202423im_/https://cdn.eso.org/images/thumb350x/eso2019a.jpg"> </div> <div class="news-description"> <div class="news-id">eso2019 — Photo Release</div> <div class="news-title">Stars and Skulls: new ESO image reveals eerie nebula</div> <div class="news-teaser"><strong>30 October 2020</strong>: This ethereal remnant of a long dead star, nestled in the belly of The Whale, bears an uneasy resemblance to a skull floating through space.

The galaxy is so far away its light has taken more than 12 billion years to reach us: we see it as it was when the Universe was just 1.4 billion years old. It is also surprisingly unchaotic, contradicting theories that all galaxies in the early Universe were turbulent and unstable.
