Recent observations have created a puzzle for astrophysicists: Since the Big Bang, fewer galaxy clusters have formed over time than were actually expected. Physicists from the university of Bonn have now confirmed this phenomenon. For the next three years, the researchers will analyze their data in even greater detail. This will put them in a position to confirm whether the theories considered valid today need to be reworked. The study is part of a series of 20 publications appearing in the professional journal Astronomy and Astrophysics. Powered by WPeMaticoRead More →

Astronomers comparing data from an ongoing major survey of the sky using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to data from earlier surveys likely have made the first discovery of the afterglow of a powerful gamma ray burst that produced no gamma rays detectable at Earth. The unprecedented discovery of this “orphan” gamma ray burst (GRB) offers key clues to understanding the aftermath of these highly energetic events. Powered by WPeMaticoRead More →

Scanning the sky for X-ray sources, ESA’s XMM-Newton X-ray observatory has been busy with the XXL Survey, its largest observational programme to date. The second batch of data from the survey has just been released, including information on 365 galaxy clusters, which trace the large-scale structure of the Universe and its evolution through time, and on 26 000 active galactic nuclei (AGN).

New Dwarf Planet Found in the Outskirts of the Solar System, Giving Astronomers More Ammunition to Search for Evidence of Planet 9 Astronomers have found a new dwarf planet way out beyond Pluto that never gets closer than 65 AUs to the Sun. It’s nicknamed “The Goblin” which is much more interesting than its science name, 2015 TG387. The Goblin’s orbit is consistent with the much-talked-about but yet-to-be-proven Planet 9. A team led by astronomer Scott Sheppard … Continue reading “New Dwarf Planet Found in the Outskirts of the Solar System, Giving Astronomers More Ammunition to Search for Evidence of Planet 9” The post NewRead More →

Good night Kepler. NASA’s Planet Hunter is Almost out of Fuel, and has Gone Into Sleep Mode The Kepler mission is coming to an end. The planet-hunting spacecraft that transformed our understanding of exoplanets and other solar systems is almost out of fuel. What little fuel remains is being held in reserve to ensure that the last of its data can be sent home. The Kepler team has placed the spacecraft in … Continue reading “Good night Kepler.

The night sky seems serene, but telescopes tell us that the universe is filled with collisions and explosions. Distant, violent events signal their presence by spewing light and particles in all directions. When these messengers reach Earth, scientists can use them to map out the action-packed sky, helping to better understand the volatile processes happening deep within space.

A trio of researchers with the European Southern Observatory and Université Côte d’Azur has found evidence showing that the gas and dust disks that form around early stars systems do not contain enough material to form the planets that develop. In their paper published in the journal Astronomy Astrophysics, Carlo Manara, A. Morbidelli and T. Guillot describe their study of data from the Atacama Large Millimeter Array (ALMA) in Chile and what they found. Powered by WPeMaticoRead More →

Could there be another planet in the universe with a society at the same stage of technological advancement as ours? To find out, EPFL scientist Claudio Grimaldi, working in association with the University of California, Berkeley, has developed a statistical model that gives researchers a new tool in the search for the kind of signals that an extraterrestrial society might emit. His method, described in an article appearing today in PNAS, could also make the search cheaper and more efficient. Powered by WPeMaticoRead More →

A study published recently in Nature has revealed the presence of a hitherto undetected component of the universe—large masses of gas surrounding distant galaxies. An international team from some 10 scientific institutions has shown that almost the whole of the early universe shows a faint glow in the Lyman-alpha line. This line is one of the key “fingerprints” of hydrogen. This detection reveals the existence of extensive masses of gas around primitive galaxies. The results of this study are based on observations made with the MUSE spectrograph on the Very Large Telescope (VLT) of the European Southern Observatory, Cerro Paranal, Chile.

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral toward a collision. For the first time, a new computer simulation that fully incorporates the physical effects of Einstein’s general theory of relativity shows that gas in such systems will glow predominantly in ultraviolet and X-ray light.
