A unique example of some of the lowest surface brightness galaxies in the universe have been found by an international team of astronomers lead by the Niels Bohr Institute. The galaxy has lower amounts of heavier elements than other known galaxies of this type. The discovery means that small low surface brightness galaxies may have more in common with the first galaxies formed shortly after the Big Bang than previously thought. The results have been published in Monthly Notices of the Royal...

A new study, published in Physical Review Letters and available online, offers that a controversial theory which challenges the existence of dark matter has been kept afloat by studies of gas-rich galaxies. Instead of calling upon dark matter, the Modified Newtonian Dynamics (MoND) theory says that the effects of gravity change in places where its pull is very low. A new paper suggests that MoND better predicts the relationship between gassy galaxies' rotation speeds and masses. However,...
