June 26, 2015 — Researchers have found evidence that enigmatic objects in nearby galaxies -- called ultra-luminous X-ray sources (ULXs) -- exhibit strong outflows that are created as matter falls onto their black ... read more

June 25, 2015 — The giant elliptical galaxy Messier 87 has swallowed an entire medium-sized galaxy over the last billion years. For the first time a team of astronomers has been able to track the motions of 300 ... read more

June 24, 2015 — Astronomers have analyzed the clouds of gas and dust from some of the earliest galaxies ever observed -- one billion years after the Big ... read more

June 24, 2015 — Active galactic nuclei are the brightest objects in the universe. They are not lit up permanently, but rather 'flicker' extremely slowly. This insight helps researchers better understand ... read more

June 23, 2015 — In late 2013, when the neutron star at the heart of one of our galaxy's oddest supernovae gave off a massive burst of X-rays, the resulting echoes -- created when the X-rays bounced off clouds ... read more

June 22, 2015 — Astronomers have discovered 854 "ultra-dark galaxies" in the Coma Cluster. The new discovery surpasses the 2014 discovery of 47 mysterious dark galaxies by more than 800 and suggests that ... read more

June 18, 2015 — Magnetic field structure of nearby galaxy provides new insights on how spiral arms form, and how gas can be funneled inward to fuel star formation at the galaxy's ... read more

June 18, 2015 — A new image shows a gathering of four cosmic companions. This quartet forms part of a group of galaxies known as the Hickson Compact Group 16, or HCG 16 -- a galaxy group bursting with dramatic star ... read more

June 18, 2015 — Astronomers have measured the mass of the supermassive black hole at the center of NGC 1097 -- a barred spiral galaxy located approximately 45 million light-years away in the direction of the ... read more

June 17, 2015 — Radio observations give new evidence for long-sought supermassive black hole in small satellite galaxy orbiting the Andromeda ... read more

June 17, 2015 — Astronomers have discovered the brightest galaxy yet found in the early Universe and found strong evidence that first generation of stars lurk within it. These previously theoretical objects were the ... read more

June 17, 2015 — Using the advanced adaptive optics system GeMS, on the Gemini South telescope, astronomers have imaged a beautiful stellar jewel-box -- a tightly packed cluster of stars that is one of the few places ... read more

June 10, 2015 — Although the Universe may seem spacious most galaxies are clumped together in groups or clusters and a neighbor is never far away. But this galaxy, known as NGC 6503, has found itself in a lonely ... read more

June 8, 2015 — ALMA's Long Baseline Campaign has produced a spectacularly detailed image of a distant galaxy being gravitationally lensed. The image shows a magnified view of the galaxy's star-forming ... read more

June 4, 2015 — Astronomers usually discover supernovae within large galaxies, where a star explodes perhaps once a century. Now a team of astronomers has used the sharp imaging capability of the Hubble Space ... read more

How to Weigh the Milky Way

June 2, 2015 — Scientists used streams produced by dissolving globular clusters to measure the weight of our galaxy and determine the location of the sun within the Milky ... read more

May 28, 2015 — In the most extensive survey of its kind ever conducted, a team of scientists have found an unambiguous link between the presence of supermassive black holes that power high-speed, ... read more

May 27, 2015 — Astronomers have discovered for the first time a rear-end collision between two high-speed knots of ejected matter from a supermassive black hole. This discovery was made while piecing together a ... read more

May 26, 2015 — Astronomers have found that the black holes located at the cores of galaxies launch fountains of charged particles, which can stir up gas throughout the galaxy and temporarily interrupt star ... read more

May 25, 2015 — NGC 6240 lies 400 million light-years away in the constellation of Ophiuchus (The Serpent Holder). This galaxy has an elongated shape with branching wisps, loops and tails. This mess of gas, dust and ... read more
