VST Captures Three-In-One
Two of the sky’s more famous residents share the stage with a lesser-known neighbour in this enormous new three gigapixel image from ESO’s VLT Survey Telescope (VST). On the right lies the faint, glowing cloud of gas called Sharpless 2-54, the iconic Eagle Nebula is in the centre, and the Omega Nebula to the left. This cosmic trio makes up just a portion of a vast complex of gas and dust within which new stars are springing to life and illuminating their surroundings.

ALMA Finds Ingredient of Life Around Infant Sun-like Stars
ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate — a chemical building block of life. This is the first ever detection of this prebiotic molecule towards solar-type protostars, the sort from which our Solar System evolved. The discovery could help astronomers understand how life arose on Earth.

ESO Signs Contracts for the ELT’s Gigantic Primary Mirror
Contracts for the manufacture of the 39-metre primary mirror of ESO’s Extremely Large Telescope (ELT) were signed today at a ceremony at ESO’s Headquarters near Munich. The German company SCHOTT will produce the blanks of the mirror segments, and the French company Safran Reosc will polish, mount and test the segments. The contract to polish the mirror blanks is the second-largest contract for the ELT construction and the third-largest contract ESO has ever awarded.

First Stone Ceremony for ESO's Extremely Large Telescope
A ceremony marking the first stone of ESO’s Extremely Large Telescope (ELT) has been attended today by the President of the Republic of Chile, Michelle Bachelet Jeria. The event was held at ESO's Paranal Observatory in northern Chile, close to the site of the future giant telescope. This milestone marked the beginning of the construction of the dome and main telescope structure of the world’s biggest optical telescope, and ushered in a new era in astronomy. The occasion also marked the connection of the observatory to the Chilean national electrical grid.

Secondary Mirror of ELT Successfully Cast
The casting of the secondary mirror blank for ESO’s Extremely Large Telescope (ELT) has been completed by SCHOTT at Mainz, Germany. The completed mirror will be 4.2 metres in diameter and weigh 3.5 tonnes. It will be the largest secondary mirror ever employed on an optical telescope and also the largest convex mirror ever produced.

VISTA Peeks Through the Small Magellanic Cloud’s Dusty Veil
The Small Magellanic Cloud galaxy is a striking feature of the southern sky even to the unaided eye. But visible-light telescopes cannot get a really clear view of what is in the galaxy because of obscuring clouds of interstellar dust. VISTA’s infrared capabilities have now allowed astronomers to see the myriad of stars in this neighbouring galaxy much more clearly than ever before. The result is this record-breaking image — the biggest infrared image ever taken of the Small Magellanic Cloud — with the whole frame filled with millions of stars.

ALMA Residencia Handed Over
The new ALMA Residencia at the ALMA Operations Support Facility has just been handed over to the Joint ALMA Observatory. The celebration event was attended by the ALMA Board and the directors of the three executives — ESO, NAOJ and NRAO. The architects who designed the building were also present. The ALMA Residencia is the last major construction item to be delivered to the ALMA project by ESO.

Newly Discovered Exoplanet May be Best Candidate in Search for Signs of Life
An exoplanet orbiting a red dwarf star 40 light-years from Earth may be the new holder of the title “best place to look for signs of life beyond the Solar System”. Using ESO’s HARPS instrument at La Silla, and other telescopes around the world, an international team of astronomers discovered a “super-Earth” orbiting in the habitable zone around the faint star LHS 1140. This world is a little larger and much more massive than the Earth and has likely retained most of its atmosphere. This, along with the fact that it passes in front of its parent star as it orbits, makes it one of the most exciting future targets for atmospheric studies. The results will appear in the 20 April 2017 issue of the journal Nature.

ALMA Captures Dramatic Stellar Fireworks
Stellar explosions are most often associated with supernovae, the spectacular deaths of stars. But new ALMA observations provide insights into explosions at the other end of the stellar life cycle, star birth. Astronomers captured these dramatic images as they explored the firework-like debris from the birth of a group of massive stars, demonstrating that star formation can be a violent and explosive process too.

Stars Born in Winds from Supermassive Black Holes
Observations using ESO’s Very Large Telescope have revealed stars forming within powerful outflows of material blasted out from supermassive black holes at the cores of galaxies. These are the first confirmed observations of stars forming in this kind of extreme environment. The discovery has many consequences for understanding galaxy properties and evolution. The results are published in the journal Nature.
