galaxy : any of the very large groups of stars and associated matter that are found throughout the universe — Webster
Galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas and dust, and an important but poorly understood component tentatively dubbed dark matter. Galaxies contain varying amounts of star systems, star clusters and types of interstellar clouds. In between these objects is a sparse interstellar medium of gas, dust, and cosmic rays. Dark matter appears to account for around 90% of the mass of most galaxies. — Wikipedia

Astronomers take first, high-resolution look at...
on April 15, 2019 at 4:23 pm
A team of astronomers used a newly commissioned radio telescope in South Korea to make the first high-resolution observations of the molecular clouds within a star-forming region of the Milky Way. The first good look at the galactic region indicated large molecular clouds about 180 light years across with a mass equal to about 100,000 masses of our sun. […]
VLA makes first direct image of key feature of...

A dusty, doughnut-shaped feature long thought to be an essential part of the 'engines' at the cores of active galaxies is seen for the first time in one of the most powerful galaxies in the Universe. […]
Dark matter is not made up of tiny black holes
on April 2, 2019 at 3:30 pm
An international team of researchers has put a theory speculated by the late Stephen Hawking to its most rigorous test to date, and their results have ruled out the possibility that primordial black holes smaller than a tenth of a millimeter make up most of dark matter. […]
Ultra-sharp images make old stars look absolutely...
on March 26, 2019 at 2:57 pm
Using high-resolution adaptive optics imaging from the Gemini Observatory, astronomers have uncovered one of the oldest star clusters in the Milky Way Galaxy. The remarkably sharp image looks back into the early history of our Universe and sheds new insights on how our Galaxy formed. […]
Giant X-ray 'chimneys' are exhaust vents for vast...

At the center of our galaxy, where an enormous black hole blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and explode. astronomers have discovered two exhaust channels -- dubbed the 'galactic center chimneys' -- that appear to funnel matter and energy away from the cosmic fireworks. […]

Research on disk galaxies sheds light on movement...
on April 23, 2019 at 12:23 pm
University of Arkansas astrophysicists have taken an important step toward solving the mystery of how disk galaxies maintain the shape of their spiral arms. Their findings support the theory that these arms are created by a wave of denser matter that creates the spiral pattern as it travels across the galaxy. […]

South Korean tech giant Samsung Electronics is "facing its biggest test ever", analysts said Tuesday after it delayed the release of its $2,000 foldable phone over screen problems. […]
A new eye on the cosmos
on April 23, 2019 at 11:10 am
How do galaxies form and evolve? And how do central supermassive black holes form in galaxies and influence their hosts? Those are two of the big questions that Tufts astronomers hope to answer when they start using a new, highly sensitive instrument that's set to come online in a few years on a landmark telescope in Hawaii. […]
