ESO observatories operated under challenging conditions in 2020 due to the unprecedented COVID-19 pandemic, having to reduce and even pause scientific observations for a few months. Nonetheless, 2020 was still a very productive year for the observatory with regard to the number of papers that were published using data from ESO telescopes, mostly obtained in previous years. A recently published report from the ESO library shows that 2020 represents the fourth consecutive year that over 1000 scientific studies using ESO data were published.
Of the 608 studies carried out using observations from the VLT and VLTI, 336 (55%) used data from the Multi Unit Spectroscopic Explorer (MUSE), the Ultraviolet-Visual Echelle Spectrograph (UVES), or from the X-shooter spectrograph. These were the three most productive VLT instruments in 2020, as was the case in 2019.
Atomic Point Contact Considerably Enhances Raman Scattering at Nanoscale
Today, nanofabrication of electronic systems has reached a 1 nm scale (10
−
9 m). The quick development of nanotechnology and nanoscience currently needs atomic-scale optical spectroscopy to define atomistic structures that will influence the functions and properties of the electronic devices.

The international research team, led by Takashi Kumagai from the Institute for Molecular Science, observed a massive improvement of Raman scattering facilitated by the development of an atomic point contact between a Si(111)-7×7 reconstructed surface and a plasmonic silver tip. This was realized using advanced low-temperature tip-enhanced Raman spectroscopy that hel
An international team led by astronomers at Queenâs University Belfast has detected a new âchemical signatureâ in the atmosphere of a planet that orbits a star other than our Sun. It may ultimately lead to an answer to the question: âAre we alone?â
The discovery by researchers from QUB; the Astrobiology Center (ABC) of the National Institutes of Natural Sciences in Tokyo and Trinity College Dublin helps pave the way to probing atmospheres of smaller rocky planets resembling the Earth.
Exploration of the atmospheres of these âextrasolarâ planets assists in the search for Earth-like exoplanets and may provide an indication of the likelihood of life on other planets.

Abstract:
Nanographene is flexible, yet stronger than steel. With unique physical and electronic properties, the material consists of carbon molecules only one atom thick arranged in a honeycomb shape. Still early in technological development, current fabrication methods require the addition of substituents to obtain a uniform material. Additive-free methods result in flimsy, breakable fibers until now.
