12 Aug 2020, 15:00 UTC With the Atacama Large Millimeter / Submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is involved, astronomers have discovered an extremely distant and therefore very young galaxy that looks surprisingly similar to our Milky Way. The galaxy is so far away that it took its light more than 12 billion years to reach us: we see it as it was when the universe was just 1.4 billion years old. It is also surprisingly less chaotic and contradicts the theories that all galaxies in the early universe were turbulent and unstable. This unexpected discovery challenges our understanding of how galaxies are formed and gives us new insights into the past of our universe. Next Previous
ESA Space Science 30 Sep 2020, 12:00 UTC ESA has released its first Solar Orbiter data to the scientific community and the wider public. The instruments contributing to this data release come from the suite of in-situ instruments that measure the conditions surrounding the spacecraft.
ESA Top News 28 Sep 2020, 08:00 UTC ESA’s new exoplanet mission, Cheops, has found a nearby planetary system to contain one of the hottest and most extreme extra-solar planets known to date: WASP-189 b. The finding, the very first from the mission, demonstrates Cheops’ unique ability to shed light on the Universe around us by revealing the secrets of these alien worlds.
NASA's Goddard Space Flight Center 25 Sep 2020, 12:25 UTC Resting on the tail of the Great Bear in the constellation of Ursa Major lies NGC 5585, a spiral galaxy that is more than it appears.
ESA Top News 25 Sep 2020, 11:29 UTC Packed safely within protective containers, SEOSAT-Ingenio was transported together with its co-passenger, the CNES French space agency’s Taranis satellite – both scheduled for launch on a Vega rocket in November. Following the airplane off-loading procedures, SEOSAT-Ingenio was then transferred on a dedicated trailer for transport to Guiana Space Centre.
NASA's Goddard Space Flight Center 24 Sep 2020, 18:30 UTC A historic moment is on the horizon for NASA’s OSIRIS-REx mission. In just a few weeks, the robotic OSIRIS-REx spacecraft will descend to asteroid Bennu’s boulder-strewn surface, touch down for a few seconds and collect a sample of the asteroid’s rocks and dust – marking the first time NASA has grabbed pieces of an asteroid, which will be returned to Earth for study.
MIT 23 Sep 2020, 16:00 UTC In 2019, the Event Horizon Telescope (EHT) Collaboration, including a team of MIT Haystack Observatory scientists, delivered the first image of a black hole, revealing M87* — the supermassive object in the center of the M87 galaxy. The EHT team has used the lessons learned last year to analyze the archival data sets from 2009 to 2013, some of which were not published before. The analysis reveals the behavior of the black hole image across multiple years, indicating persistence of the crescent-like shadow feature, but also variation of its orientation — the crescent appears to be wobbling. The full results appear today in The Astrophysical Journal in an article titled, “Monitoring the Morphology of M87* in 2009–2017 with the Event Horizon Telescope.”

Universe Today 30 Sep 2020, 20:38 UTC The detection of phosphine in Venus’ atmosphere was one of those quintessential moments in space science. It was an unexpected discovery, and when combined with our incomplete understanding of planetary science, and our wistful hopefulness around the discovery of life, the result was a potent mix that lit up internet headlines.
Centauri Dreams 30 Sep 2020, 15:09 UTC The European Space Agency’s CHaracterising ExOPlanet Satellite (CHEOPS) space telescope reached space in December of 2019, achieving a Sun-synchronous orbit some 700 kilometers up. The instrument has begun its observations of stars near the Sun that are already known to have planetary companions. The idea is to use the 30 cm optical telescope to constrain radius information for these worlds, previously identified in transit and radial velocity studies.
EarthSky Blog 30 Sep 2020, 12:10 UTC Image via NASA/ SDO/ AIA, EVE, HMI science teams.By Graham JonesSolar flares are brief eruptions of intense high-energy radiation from the sun’s surface. They’re associated with sunspots, coronal mass ejections and other signs of high activity on the sun, during its 11-year cycle. Activity on the sun creates what’s known as space weather, which can have an impact here on Earth. For example, a big solar flare can result in charged particles hurled toward Earth that cause disturbances in the power grid, satellites, GPS and airlines. But understanding when and why these powerful solar flares happen is one of most difficult challenges in astrophysics.Now, a team of researchers in Japan think they may have found a way to predict large solar flares and make better forecasts of space weather. Kanya Kusano, Director of the Institute for Space-Earth Environmental Research, Nagoya University, and his team developed a physics-based model to predict imminent large solar flares. The study was published in the journal Science on July 31, 2020. Kusano spoke about about work.What is the Institute for Space-Earth Environmental Research, and what’s your role?Kanya Kusano: The human environment is so extended, it even spreads into space. Our institute was established in 2015 ...
Universe Today 29 Sep 2020, 16:24 UTC Is it a new asteroid mini–moon or a human-made mini-moon? That’s the question about a small object approaching Earth, called 2020 SO. NASA’s Small Body Database predicts the object will captured by Earth’s gravity in October 2020 and temporarily be trapped in orbit.
SciTech Daily 28 Sep 2020, 09:42 UTC Eight months after the space telescope CHEOPS started its journey into space, the first scientific publication using data from CHEOPS has been issued. Using data from CHEOPS, scientists have recently carried out a detailed study of the exoplanet WASP-189b. Willy Benz, professor of astrophysics at the University of Bern and head of the CHEOPS consortium, was delighted about the findings: “These observations demonstrate that CHEOPS fully meets the high expectations regarding its performance.”
