  Milky Way Lit Up By Very Large Telescope‘s Laser Beams

  May 30, 2022, Chile: This picture shows the Milky Way behind four powerful laser beams leaving Unit Telescope 4, or ââ¬ËYepunââ¬â¢, at ESOââ¬â¢s Very Large Telescope (VLT) in Chileââ¬â¢s Atacama desert. These form the VLTââ¬â¢s 4 Laser Guide Star Facility, which enables astronomers to take extremely crisp images of the cosmos by employing a technology known as adaptive optics. Using adaptive optics, telescopes are able to correct for the effects of atmospheric turbulence, which causes the ââ¬Åtwinklingââ¬Â and blurring of stars and other objects in the sky. To do this, a deformable mirror reshapes itself up to 1000 times per second based on the observed turbulence. Astronomers measure turbulence by monitoring a bright star in the field of view. If there isnââ¬â¢t a suitable star, they create artificial stars in the Earthââ¬â¢s upper atmosphere using lasers. The lasers in this image have a very specific orange-yellow colour (with a wavelength of 589 nm), exciting sodium atoms about 90 km above grou...

  ‘Black Hole Police‘ Make Remarkable Discovery Outside our galaxy

  July 18, 2022, Leuven, Belgium: VIDEO AVAILABLE: CONTACT INFO@COVERMG.COM TO RECEIVE**This composite image shows the star-forming region 30 Doradus, also known as the Tarantula Nebula. The background image, taken in the infrared, is itself a composite: it was captured by the HAWK-I instrument on ESOââ¬â¢s Very Large Telescope (VLT) and the Visible and Infrared Survey Telescope for Astronomy (VISTA), shows bright stars and light, pinkish clouds of hot gas. The bright red-yellow streaks that have been superimposed on the image come from radio observations taken by the Atacama Large Millimeter/submillimeter Array (ALMA), revealing regions of cold, dense gas which have the potential to collapse and form stars. The unique web-like structure of the gas clouds led astronomers to the nebulaââ¬â¢s spidery nickname.A team of international experts have found a stellar-mass black hole in the Large Magellanic Cloud, a neighbour galaxy to our own. .Moreover, they found that the star that gave rise to the black hole va...

  ESO Telescope Images A Spectacular Cosmic Dance

  August 16, 2022: ESOââ¬â¢s Very Large Telescope (VLT) has imaged the result of a spectacular cosmic collision ââ¬â the galaxy NGC 7727. This giant was born from the merger of two galaxies, an event that started around a billion years ago. At its centre lies the closest pair of supermassive black holes ever found, two objects that are destined to coalesce into an even more massive black hole...Just as you may bump into someone on a busy street, galaxies too can bump into each other. But while galactic interactions are much more violent than a bump on a busy street, individual stars donââ¬â¢t generally collide since, compared to their sizes, the distances between them are very large. Rather, the galaxies dance around each other, with gravity creating tidal forces that dramatically change the look of the two dance partners. ââ¬ËTailsââ¬â¢ of stars, gas and dust are spun around the galaxies as they eventually form a new, merged galaxy, resulting in the disordered and beautifully asymmetrical shape that we...

  Astronomers Find Distant Gas Clouds With Leftovers Of The First Stars

  May 3, 2023: PICTURE SHOWS: This artistââ¬â¢s impression shows a distant gas cloud that contains different chemical elements, illustrated here with schematic representations of various atoms...STORY COPY: Using ESOââ¬â¢s Very Large Telescope (VLT), researchers have found for the first time the fingerprints left by the explosion of the first stars in the Universe. They detected three distant gas clouds whose chemical composition matches what we expect from the first stellar explosions...、クレジット：©Ｃｏｖｅｒ　Ｉｍａｇｅｓ／Ｃｏｖｅｒ　Ｉｍａｇｅｓ　ｖｉａ　ＺＵＭＡ　Ｐｒｅｓｓ／共同通信イメージズ　※Ｕｎｉｔｅｄ　Ｋｉｎｇｄｏｍ　Ｒｉｇｈｔｓ　ＯＵＴ
