What you’ll discover in this blog post:
  • Find out about the year-end press coverage of ESO’s 2018 discoveries and images
  • See which ESO images and discoveries were selected as the best of 2018
Each year it seems that ESO makes ever more impressive discoveries, with 2018 bringing us a host of new exoplanets — including the first image of a newborn planet, the discovery of water on known exoplanets, the confirmation of a supermassive black hole at the heart of the Milky Way, and much more. These successes, as well as a host of beautiful images, were highlighted in various agencies’ and organisations’ roundups of 2018’s top astronomical discoveries and images.

In Futura Sciences’Astronomy: Ten news items that marked 2018”, first place goes to the confirmation by ESO’s incredibly sensitive GRAVITY instrument that a supermassive black hole exists at the heart of the Milky Way. The discovery of a “super-Earth” planet orbiting Barnard’s Star using data from ESO’s HARPS instrument comes in fourth place.

Austrian technology news site, Futurezone, also highlighted ESO’s exciting GRAVITY observations of the immediate neighbourhood of our galaxy’s central black hole in their round-up of the best science stories of 2018. But this was for a slightly different piece of research that observed clumps of gas zooming around the black hole’s event horizon.

In their review of the most stunning space pictures of 2018, National Geographic shared ESO Photo Ambassador Gerd Hūdepohl's beautiful photo of the Very Large Telescope’s four laser guide stars, as well as our image of NGC 2467, the star-bearing Skull and Crossbones Nebula:

The Pirate of the Southern Skies
Active star-forming region NGC 2467 is packed with dust, gas and bright young stars. This vivid image was was captured with the FORS instrument on ESO’s Very Large Telescope. The beautiful region is nicknamed the Skull and Crossbones nebula, due to its resemblance to a grinning skull.

Space.com ended the year with a list of the most fascinating exoplanets found in 2018. The super-Earth discovered around Barnard’s Star made it to the top spot, with second place graced by the discovery of a newborn planet orbiting a dwarf star by ESO’s planet-hunter SPHERE. Coming in at number four is the detection by HARPS of a Mercury-like planet the size of the Earth, with a metal core that makes up two-thirds of its mass.

The above image of the baby planet discovered by SPHERE was also listed by the Mexican Uno TV as one of the 15 best space pictures of 2018.

Two ESO images were featured by the Belgian news site Het Laatste Nieuws as “The five most beautiful space photos of 2018”: the incandescent Skull and Crossbones nebula (NGC 2467) and the bountiful RCW 38 star-forming region.

New observations made using ESO’s Very Large Telescope showcase the ionised hydrogen region RCW 38 in all its glory. This image was taken during testing of the HAWK-I camera with the GRAAL adaptive optics system. It shows the star cluster inside RCW 38 and the surrounding clouds of brightly glowing gas in exquisite detail, with dark tendrils of dust threading through the bright core of this young gathering of stars.

Wikipedia’s list of 278 significant science events in 2018 highlighted three results with ESO involvement:

The national Danish Broadcasting Corporation lists ESO’s discovery of liquid water on TRAPPIST-1 planets as one of the ten most important scientific discoveries of 2018. At just 40 light-years away, the ultra-cold dwarf star TRAPPIST-1 hosts seven planets, each with their own unique properties.

The discoveries made using ESO’s cutting-edge telescopes and instruments are only possible with the hard work of the scientists, engineers and other ESO staff. ESO hopes to bring you even more exciting news and beautiful images in 2019 and the years to come!
