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...

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...

A see-through galaxy questions the need for dark matter
... component of the Universe – making up a whopping ~80 percent of its mass – and the invisible glue that holds galaxies and galaxy clusters together. Although it has never been directly observed, scientists are confident that this elusive material...

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...
