Sep. 15, 2016 — A black hole destroying a star, an event astronomers call 'stellar tidal disruption,' releases an enormous amount of energy, brightening the surroundings in an event called a flare. Two new ... read more

Sep. 15, 2016 — New data from ALMA reveal that the black hole at the center of a galaxy named NGC 1068 is actually the source of its own dusty torus of dust and gas, forged from material flung out of the black ... read more

Sep. 15, 2016 — Many galaxies are found to have an extremely bright core powered by a supermassive black hole. These cores make "active galaxies" some of the brightest objects in the Universe. They are ... read more

Sep. 14, 2016 — Scientists have taken a critical step towards understanding why different types of galaxies exist throughout the Universe. The research, made possible by cutting-edge instrumentation, means that ... read more

Sep. 13, 2016 — Astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been observed. Now the ... read more

Sep. 12, 2016 — Scientists can explain why the universe has enough energy to become transparent. The study marks the first quantitative study of how the gas content within galaxies scales with the amount of ... read more

Sep. 12, 2016 — Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant ... read more

Sep. 8, 2016 — The central energy source of enigmatic pulsating Ultra Luminous X-ray sources (ULX) could be a neutron star according to numerical simulations. ULXs, which are remarkably bright X-ray sources, were ... read more

Sep. 7, 2016 — Computer simulations of a spherical collection of stars known as 'NGC 6101' reveal that it contains hundreds of black holes, until now thought impossible. Recent observations already found ... read more

Sep. 7, 2016 — Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own ... read more

Sep. 7, 2016 — A fossilized remnant of the early Milky Way harboring stars of hugely different ages has been revealed by an international team of astronomers. This stellar system resembles a globular cluster, but ... read more

Detailed Age Map Shows How Milky Way Came Together

Sep. 6, 2016 — Using colors to identify the approximate ages of more than 130,000 stars in the Milky Way's halo, astronomers have produced the clearest picture yet of how the galaxy formed more than 13.5 ... read more

Sep. 5, 2016 — Research suggests that virtually all of Earth's life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and an embryonic planet similar to ... read more

Sep. 5, 2016 — If two galaxies collide, the merging of their central black holes triggers gravitational waves, which ripple throughout space. An international research team has now calculated that this occurs ... read more

Sep. 2, 2016 — Long-term observations with the Hubble Space Telescope revealed that Eta Carinae, a very massive star system that has puzzled astronomers since it erupted in a supernova-like event in the mid 19th ... read more

Sep. 2, 2016 — ESA's Planck satellite has revealed that the first stars in the Universe started forming later than previous observations of the Cosmic Microwave Background indicated. This new analysis also ... read more

Aug. 31, 2016 — Scientists have discovered three giant planets in a binary star system composed of stellar 'twins' that are also effectively siblings of our Sun. One star hosts two planets and the other ... read more

The Genesis Project: New Life on Exoplanets

Aug. 31, 2016 — Can life be brought to celestial bodies outside our solar system which are not permanently inhabitable? This is the question with which experts are dealing in a recent ... read more

Aug. 30, 2016 — Astronomers have charted the rise and fall of galaxies over 90 percent of cosmic history. The FourStar Galaxy Evolution Survey has built a multicolored photo album of galaxies as they grow from their ... read more

Aug. 29, 2016 — For years, astronomers have puzzled over a massive star lodged deep in the Milky Way that shows conflicting signs of being extremely old and extremely young. Researchers initially classified the star ... read more
