Jan. 16, 2017 — 49 Lib, a relatively bright star in the southern sky, is twelve billion years old rather than just 2.3 billion. For many decades, researchers were stumped by conflicting data pertaining to this ... read more

Jan. 12, 2017 — Galaxies are merging all the time, even our own galaxy, the Milky Way. But how these mergers occur isn't entirely clear. An American astrophysicist will use a National Science Foundation grant ... read more

Jan. 11, 2017 — Astronomers have discovered giant halos around early Milky Way type galaxies, made of photons (elementary particles of light) that have struggled to escape ... read more

Jan. 8, 2017 — A black hole under investigation is so hidden that it requires highly sensitive observations in the highest energy X-rays to classify it as obscured. But they give themselves away when material they ... read more

Research Supports Role of Supernovas in Measuring Pace at Which the Universe Expands

Jan. 6, 2017 — A team of research scientists recently published a paper marking the importance of Type Ia supernovas in measuring the pace at which the universe expands. Type Ia supernovas are among the very ... read more

Jan. 6, 2017 — Astronomers have discovered a cosmic one-two punch never seen before. By combining data from some of the best X-ray, optical and radio telescopes in the world, researchers have found out what happens ... read more

Jan. 5, 2017 — An unparalleled image from NASA's Chandra X-ray Observatory is giving astronomers the best look yet at the growth of black holes over billions of years beginning soon after the Big Bang. This is ... read more

Jan. 4, 2017 — New research by cosmologists confirms the accuracy of Type Ia supernovae in measuring the pace at which the universe expands. The findings support a widely held theory that the expansion of the ... read more

Dec. 21, 2016 — The Atacama Large Millimeter/submillimeter Array (ALMA) in Chile has begun observing in a new range of the electromagnetic spectrum. This has been made possible thanks to new receivers installed at ... read more

Dec. 21, 2016 — Astronomers have found one of the Universe's biggest superclusters of galaxies near the Milky Way. The Vela supercluster, which had previously gone undetected as it was hidden by stars and dust ... read more

Dec. 20, 2016 — Distant galaxies can be seen as they were when most of today's stars were being born, report scientists, answering longstanding questions about mechanisms of star formation billions of years ... read more

Dec. 20, 2016 — The sheer observing power of the NASA/ESA Hubble Space Telescope is rarely better illustrated than in an image such as this. This glowing pink nebula, named NGC 248, is located in the Small ... read more

Dec. 20, 2016 — Physicists have conducted the first precision study of antihydrogen, the antimatter equivalent of ... read more

Dec. 19, 2016 — The world's largest digital survey of the visible Universe, mapping billions of stars and galaxies, has been publicly ... read more

Dec. 19, 2016 — Researchers have just published the most precise analysis of the fluctuations in the gamma-ray background to date. By making use of more than six years of data, the researchers found two different ... read more

Population of Neutron Stars Can Generate Gravitational Waves Continuously

Dec. 14, 2016 — A population of neutron stars has a spin rate that is much higher than that calculated by the conventional method, say scienitsts. Gravitational waves continuously emitted by the star bring this high ... read more

Dec. 13, 2016 — Researchers have created a new magnetic mirror-based device that could one day help cosmologists discover new details about ripples in space-time known as gravitational waves, particularly those ... read more

Dec. 7, 2016 — Analysis of a giant new galaxy survey suggests that dark matter may be less dense and more smoothly distributed throughout space than previously thought. An international team used data from the Kilo ... read more

Dec. 6, 2016 — Astronomers have identified what they believe to be the second generation of stars, shedding light on the nature of the universe's first ... read more

Embryonic Cluster Galaxy Immersed in Giant Cloud of Cold Gas

Dec. 1, 2016 — Astronomers studying a cluster of still-forming protogalaxies seen as they were more than 10 billion years ago have found that a giant galaxy in the center of the cluster is forming from a ... read more
