Study explains why galaxies stop creating stars

9 July 2016 Astronomy Now

The processes that cause galaxies to cease star formation are not well understood and constitute an outstanding problem in the study of the evolution of elliptical, spiral (such as the Milky Way) and irregular galaxies. Now, using a large sample of around 70,000 galaxies, a team of researchers may have an explanation for why some stop creating stars.


A team of super bright galaxies in the early universe

In 2015, Dr. David Sobral of Lancaster University led a team that found the first example of a spectacularly bright galaxy in the young universe named CR7 which may harbour first generation stars. Now, astronomers have identified a family of incredible galaxies that could shed further light on the transformation of the early universe known as the “epoch of reionisation.”


Searching for the most habitable galaxies

A team of UK scientists is attempting to build the first cosmobiological model to explore the habitability of the universe. Using a survey of more than 140,000 galaxies nearest to Earth, the team found that elliptical galaxies — rather than spirals like our Milky Way — could be the most probable “cradles of life”.
