Carnegie Science 9 Jul 2018, 13:00 UTC Carnegie’s Eduardo Bañados led a team that found a quasar with the brightest radio emission ever observed in the early universe, due to it spewing out a jet of extremely fast-moving material. Bañados’ discovery was followed up by Emmanuel Momjian of the National Radio Astronomy Observatory, which allowed the team to see with unprecedented detail the jet shooting out of a quasar that formed within the universe’s first billion years of existence.
ESO Top News 4 Jul 2018, 14:00 UTC On 2 July 2019 one of nature’s most impressive phenomena will be visible from ESO’s La Silla Observatory in Chile — a total solar eclipse. As these are very rare — the next one visible from La Silla will occur in 212 years — ESO is organising a campaign of observing and outreach activities on site, allowing the general public to experience this spectacular event. Tickets to participate will be available from 13:00 CEST/07:00 CLT on Friday 13 July 2018.
NASA's Goddard Space Flight Center 3 Jul 2018, 15:00 UTC A new study using data from NASA’s NuSTAR space telescope suggests that Eta Carinae, the most luminous and massive stellar system within 10,000 light-years, is accelerating particles to high energies — some of which may reach Earth as cosmic rays.
NASA's Jet Propulsion Laboratory News and Features 2 Jul 2018, 15:27 UTC NASA's Dawn spacecraft reached its lowest-ever and final orbit around dwarf planet Ceres on June 6 and has been returning thousands of stunning images and other data. The flight team maneuvered the spacecraft into an orbit that dives 22 miles (35 kilometers) above the surface of Ceres and viewed Occator Crater, site of the famous bright deposits, and other intriguing regions. In more than three years of orbiting Ceres, Dawn's lowest altitude before this month was 240 miles (385 kilometers), so the data from this current orbit bring the dwarf planet into much sharper focus. These low orbits have revealed unprecedented details of the relationships between bright and dark materials in the region of Vinalia Faculae. Dawn's visible and infrared mapping spectrometer had previously found the bright deposits to be made of sodium carbonate, a material commonly found in evaporite deposits on Earth. Last week Dawn fired its ion engine, possibly for the final time, to fly nearer Cerealia Facula, the large deposit of sodium carbonate in the center of Occator Crater.
Max Planck Institute for Astronomy 2 Jul 2018, 15:00 UTC Astronomers have found that the atmosphere of the hottest known exoplanet, the hot Jupiter-like planet KELT-9b, is "boiling off," with the escaping gas being captured by the host star. Using the CARMENES instrument at Calar Alto Observatory, Fei Yan and Thomas Henning of the Max Planck Institute for Astronomy in Heidelberg were able to detect the escaping hydrogen atmosphere of the planet. Their observations indicate a spread-out hydrogen envelope that is being pulled towards the host star.
ESO Top News 2 Jul 2018, 10:00 UTC SPHERE, a planet-hunting instrument on ESO’s Very Large Telescope, has captured the first confirmed image of a planet caught in the act of forming in the dusty disc surrounding a young star. The young planet is carving a path through the primordial disc of gas and dust around the very young star PDS 70. The data suggest that the planet’s atmosphere is cloudy.
Harvard-Smithsonian Center for Astrophysics 29 Jun 2018, 12:41 UTC A new study provides new clues indicating that an exoplanet 500 light-years away is much like Earth. Kepler-186f is the first identified Earth-sized planet outside the Solar System orbiting a star in the habitable zone. This means it's the proper distance from its host star for liquid water to pool on the surface.
NASA's Goddard Space Flight Center 29 Jun 2018, 12:00 UTC This rich and dense smattering of stars is a massive globular cluster, a gravitationally bound collection of stars that orbits the Milky Way. Globular clusters are denser and more spherical than open star clusters like the famous Pleiades. They typically contain hundreds of thousands of stars that are thought to have formed at roughly the same time.
ESA Top News 28 Jun 2018, 08:00 UTC After completion of an independent review, a new launch date for the James Webb Space Telescope has been announced: 30 March 2021. "The James Webb Space Telescope is the most ambitious and complex astronomical project ever built, and bringing it to life is a long, meticulous process. The wait will be a little longer now but the breakthrough science that it will enable is absolutely worth it," says Günther Hasinger, ESA Director of Science.
