With the participation of the newly commissioned Greenland Telescope and a dramatically improved recording rate across the array, the 2018 observations give us a view of the source independent from the first observations in 2017.</p> Fri, 19 Jan 2024 15:49:01 +0000 webfull 196691 at /channels /channels/channels/news/astronomers-reveal-first-image-black-hole-heart-our-galaxy-339571 <p>Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes. Astronomers from Æ»¹ûÒùÔº were part of this global effort.</p> Thu, 12 May 2022 16:56:19 +0000 webfull 180138 at /channels /channels/channels/news/telescopes-unite-unprecedented-observations-famous-black-hole-330409 <p>In April 2019, scientists released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told. Æ»¹ûÒùÔº astronomers<i> </i>were part of this global effort.</p> <p>Data from 19 observatories are now being released that promise to give unparalleled insight into this black hole and the system it powers, and to improve tests of Einstein’s General Theory of Relativity.</p> Wed, 14 Apr 2021 20:01:18 +0000 webfull 169871 at /channels /channels/channels/news/first-images-magnetic-fields-edge-black-hole-m87-galaxy-330020 <p>The Event Horizon Telescope (EHT) collaboration, which includes researchers from Æ»¹ûÒùÔº, who produced the first ever image of a black hole, has revealed this week a new view of the massive object at the centre of the M87 galaxy: how it looks in polarized light. This is the first time astronomers have been able to measure polarization, 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.</p> Thu, 25 Mar 2021 15:41:00 +0000 webfull 169425 at /channels /channels/channels/news/astronomers-capture-first-image-black-hole-296142 <p>The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.</p> Wed, 10 Apr 2019 13:22:18 +0000 webfull 148262 at /channels /channels/channels/news/mcgill-researchers-honoured-quebec-science-list-top-discoveries-292807 <p> Thu, 03 Jan 2019 14:26:52 +0000 webfull 144543 at /channels /channels/channels/news/latest-gravitational-wave-detection-opens-new-era-astronomy-278031 <p><span>The discovery of a gravitational wave caused by the merger of two neutron stars, reported today by a collaboration of scientists from around the world, opens a new era in astronomy. It marks the first time that scientists have been able to observe a cosmic event with both light waves -- the basis of traditional astronomy -- and gravitational waves, the ripples in space-time predicted a century ago by Albert Einstein’s general theory of relativity.</span></p> Mon, 16 Oct 2017 14:04:16 +0000 webfull 131941 at /channels
