The dwarf galaxy problem
...physics, limited optical surveys and starless ‘dark galaxies’ are some of the possibilities suggested to account...very interesting object indeed! Combing the Virgo Cluster The dark galaxy idea is particularly intriguing - and perhaps not as outlandish ...

Distant Milky Way look-alike is a breakthrough in the field of galaxy formation
... after the late astronomer Arthur M. Wolfe, was found so early in the Universe, this proved to be something of a conundrum. Galaxy evolution is now being called into question again after the discovery of a similar breakthrough with an object called...

Astronomers find a galaxy with no dark matter
... a thousand times fewer stars. Because of this characteristic AGC 114905 is classified as an ultra-diffuse dwarf galaxy, with the name “dwarf galaxy” referring to its luminosity and not to its size. When visualised on a graph showing the distance...

Astronomers find ultra diffuse galaxy heavy in dark matter
... matter content. "Globular clusters, made up of hundreds of thousands of stars, orbit within the gravitational field of the ultradiffuse galaxy," adds Aaron Romanowsky of San José State University (USA) one of the authors of the article. "The heavier...

Rare, massive, starburst galaxies captured in detail by Hubble
... a phenomenon called gravitational lensing, which occurs when the intense gravity of a massive object such as a galaxy or cluster of galaxies bends and magnifies the light of fainter, more distant background sources. Utilising this natural magnifying...
