19 januari 2018: The development of a new spectrometer for the Morita Array, which forms part of the Atacama Large Millimeter/submillimeter Array (ALMA), has been approved by the ALMA Board. Developed by Japan, the Morita Array is composed of twelve 7-metre antennas and four 12-metre antennas. The new spectrometer will be dedicated to the four 12-metre antennas under the ALMA Future Development Program, which aims to maintain ALMA’s capacity to produce remarkable scientific results. ALMA creates very sharp images by linking multiple antennas together to form a giant virtual telescope that can be up to 16 kilometres in diameter. The Morita Array forms one part of ALMA, and comprises antennas with small separations [1]. Radio waves collected by the ACA antennas are processed by the ACA Correlator, which combines the data from all of the antennas [2]. At present the ACA Correlator is optimised to process signals from the twelve 7-metre antennas, the ...

21 december 2017: On 19 December 2017 in Brussels, ESO’s Director General, Xavier Barcons, met the European Commissioner for Research, Science and Innovation, Carlos Moedas, and the EC Director-General of Research and Innovation, Robert-Jan Smits. The Commissioner and ESO Director General discussed ways to reinforce the relationship between the European Commission and ESO in order to further the development of fundamental science across the European Research Area. ESO’s role as the main driver for ground-based astronomy in Europe gives it a unique responsibility to ensure that collaboration in astronomy infrastructure, instrumentation and science is well-fostered. The meeting addressed the development of the European Strategy Forum for Research Infrastructures (ESFRI) which currently lists ESO’s Extremely Large Telescope as a landmark European infrastructure. ESO’s Director General also offered ESO’s expertise towards supporting the governance of the European Open Science Cloud (EOSC) initiative and in particular with helping to improve the stewardship of archive data in ...

18 december 2017: ESO has signed a new agreement with TOPTICA, the German photonics company, for the production of lasers to be used in ESO’s Extremely Large Telescope (ELT) adaptive optics system. TOPTICA [1], in partnership with the Canadian company MPB Communications Inc. (MPBC) [2], will build at least four laser sources for the ELT [3], helping the telescope to achieve unprecedented spatial resolution for an optical/infrared ground-based telescope. The ELT is scheduled to see first light in 2024. The laser system for the adaptive optics system on the ELT will be based on the Four Laser Guide Star Facility (4LGSF) on ESO’s Very Large Telescope (VLT). The Adaptive Optics Facility, which uses the 4LGSF, has already shown spectacular improvement in image sharpness on the VLT (eso1724). The TOPTICA/MPBC Guide Star Alliance was the main contractor for the laser system on the VLT (eso1613). Adaptive optics compensate for the blurring effect of the ...

7 december 2017: ESO’s governing body, the Council, has just authorised additional spending to cover the cost of both the five inner rings of segments for the main mirror (M1) of the Extremely Large Telescope (ELT), and one spare set of 133 mirror segments (one sixth of the total M1), and also an additional mirror segment maintenance unit. The decision was made at the recent meeting of the Council in Garching, Germany, after the positive recommendation by the ESO Finance Committee and made possible by an improved funding scenario. The ELT is a revolutionary ground-based telescope concept which will have a 39-metre main mirror made of 798 hexagonal segments. It will be the largest optical telescope in the world: “the world’s biggest eye on the sky”. First light for the ELT is targeted for 2024. Up to now the inner five rings of segments of the ELT primary mirror were in Phase 2 ...

27 november 2017: The Universe isn’t empty space — it’s full of dust! Some regions are in fact very, very dusty. New baby stars, for example, are surrounded by a disc of dust that feeds material to the young star, causing it to grow. This vital stage in a star’s young life must be closely studied in order to better understand stellar evolution. However, seeing through dust is difficult for many telescopes. That is where ALMA comes in. ESOcast 139 shows how the unique observational capabilities of ALMA allows astronomers to learn about otherwise hidden objects in our Universe.

The school students will help FORSCHA participants experience the capacity of both current and new ESO telescopes to probe the mysteries of the Universe otherwise beyond ...

2 november 2017: What happened at the beginning of the Universe? It’s a question astronomers have pondered for a long time. Whilst we can’t actually travel back in time, astronomers are able to see into the past and observe galaxies and stars that were made when our Universe was still very young. Because light travels at a finite speed, the further away an object is, the longer its light has taken to reach us — so we see distant objects as they were in the past. To see the most distant celestial objects astronomers use some of the world’s most advanced telescopes, many of them unique — like ALMA. ESOcast 135 describes how ALMA enables astronomers see into the past and learn more about what our Universe was like when it was young.

31 oktober 2017: The Next Generation Transit Survey (NGTS) instrument at ESO’s Paranal Observatory in northern Chile has found its first exoplanet, a hot Jupiter orbiting an M-dwarf star [1] now named NGTS-1. The planet, NGTS-1b, is only the third gas giant to have been observed transiting an M-dwarf star, following Kepler-45b and HATS-6b. NGTS-1b is the largest and most massive of these three, with a radius of 130% and a mass of 80% those of Jupiter. The NGTS uses an array of twelve 20-centimetre telescopes to search for the tiny dips in the brightness of a star caused when a planet in orbit around it passes in front of it (“transits”) and blocks some of its light. Once NGTS-1b had been discovered its existence was confirmed by follow-up observations at ESO’s La Silla Observatory: photometric observations with EulerCam on the 1.2-metre Swiss Leonhard Euler Telescope; and spectroscopic investigations with the HARPS instrument ...

16 oktober 2017: ESO’s telescopes have observed for the first time the visible counterpart to a gravitational wave source. Marking the start of a new era of multi-messenger astronomy, this rare event was captured in extraordinary detail. The observations unveil a high-energy event, known as a kilonova, that can finally be connected to the merging of two neutron stars, stellar remnants that emit gravitational waves as they spiral towards each other and then collide in a spectacular explosion. ESOcast 133 describes what was observed by ESO’s telescopes in Chile, how telescopes around the world found the kilonova, and what astronomers have learned about this newly observed astronomical phenomenon.
