This is the ESOcast cutting-edge science and life behind the scenes at ESO the European Southern Observatory ESO operates three world-class observatories in Chile astronomer use these telescopes to study objects both close to home in the solar system and all the way out to the farthest reaches of the known Universe observations with ESO telescopes have led to many breakthrough in astronomy and over the years have been responsible for some truly remarkable findings. Here is our list of ESO's top 10 astronomical discoveries so far. Astronomers using ESO's Very Large Telescope have discovered by far the brightest galaxy yet found in the early Universe and found strong evidence that examples of the first generation of stars lurk within it stars that were previously only theoretical . These massive brilliant objects were the creators of the first heavy elements in history elements that are necessary to forge the stars we see around us today the planets that orbit them and life as we know it ESO Telescopes have provided definitive proof that long gamma ray bursts are linked with the climatic explosions of massive stars there for solving an enduring mistery a telescope at La Silla was also able to observe the visible light from a short gamma-ray burst for the first time showing that this family of objects most likely originates from colliding neutron stars. Astronomers using ESO's HARPS instrument in 2010 discovered a planetary system containing at least five planets orbiting the sun-like star HD 10180 they also found evidence that two other planets may be present one of which if confirmed would be among the lowest mass exoplanets ever found newer observations and the analysis of the data suggests that they could be even more planets around this star. ESO's Very Large Telescope was used to detect carbon monoxide molecules in a remote galaxies seen as it was 11 billions years ago a feat that have remained elusive for 25 years this allowed astronomers to obtain the most precise measurement of the cosmic temperature at such a remote epoch and it matched the temperature predicted by the Big Bang Theory. The atmosphere around a super-earth exo planet was analyzed for the first time using the VLT the planet which is known as GJ 1214b was studied at it passed in front o its parent star and some of the star light filtered through the planet's atmosphere the atmosphere was found to be either mostly water in the form of steam or dominated by thick clouds or haze Using ESO's VLT astronomers measured the age of the oldest star known in the in the Milky Way at 13.2 billion years old the star was born in the earliest era of star formation in the Universe uranium was also detected in a milky way star and used as an independent estimate of the edge of the galaxy The VLT obtained the first ever image of a planet outside our solar system the planet which has a mass about five times out of Jupiter orbits a failed star a brown dwarf at a distance of fifty five times the average distance between the Earth and the Sun. In 2014 ALMA the Atacama Large Millimeter/Submillimeter Array reveled remarkable details of a solar system that is forming the images of HL Tauri where the sharpest ever made at submillimetre wavelengths they show how forming planets are vacuuming up dust and gas in a proto planetary disc one of ESO's proudest moments came when two independent research teams including ESO staff arrived at a truly revolutionary finding that the Cosmos is not only expanding but that it is doing so at an increasing rate the findings of the separate teams were based on observations of exploding stars or Supernova including measurements made from ESO telescopes at La Silla at Paranal this discovery was rewarded with the 2011 nobel prize in physics And finally several of ESO's flagship telescopes were used in a 20-year study to obtain the most detailed view ever of the surroundings of the monster lurking at the heart of our Galaxy a supermassive Black Hole. Astronomy is always moving forward and ESO's Top 10 scientific discoveries are not set in stone as long as astronomers continue to study the Universe at ESO's Observatory unexpected and illuminating discoveries will follow who knows what exciting discoveries await? and will find their way onto this list in the future.
