A new discovery can help determine where all the stars in the universe’s galaxies actually come from.
Astronomers have taken a forensic approach to study the stellar halo of a galaxy to reveal hidden secrets on how such galaxies were formed.
Our universe’s most exciting days are well behind us, with new research showing the universe is now slowly but surely dying.
Meet the supermassive black hole that defied the model.
What happens to a galaxy when it runs out of the stuff needed to forge new stars?
Several dwarf galaxies have been discovered close to our own Milky Way and are adding to our understanding of how galaxies form. But why haven’t astronomers seen them before?
Clusters of galaxies have back-stories worthy of a Hollywood blockbuster: their existences are marked by violence, death and birth, arising after extragalactic pile-ups where groups of galaxies crashed…
A supermassive black hole has been found in an ultracompact dwarf galaxy – the smallest galaxy known to contain such a massive black hole. This finding, published today in Nature, suggests that supermassive…
A piece of the galaxy formation puzzle may have fallen into place, thanks to a team of European and American astronomers peering into the depths of our early universe. According to new research published…
Over the last few years we’ve been studying the orbits of dwarf galaxies and we expecting to find them buzzing at random around large galaxies. But looking out into the universe, we see some dwarfs undertaking…
A galaxy more than 12 billion light years from Earth is heading for a “red and dead” future because it is running out of the fuel needed to make new stars. The galaxy, known as ALESS65, is an ultra-luminous…
A team of international astronomers has developed a more precise way to deduce the ages of stars and to pinpoint when our…
Galaxies arranged in delicate strings have been discovered in the huge, empty regions of the universe called voids. A research…
Matter escaping from the clutches of mysterious black holes may be responsible for forming stars, according to new research that explores how galaxies are formed. Much has been learnt about black holes…
Scientists in the US have successfully used a new NASA telescope to help improve our understanding of how black holes and galaxies evolve. Using data taken by the Nuclear Spectroscopic Telescope Array…
Deep images of the sky reveal that the universe contains billions of galaxies. Some, such as our own Milky Way, are immense, containing hundreds of billions of stars. Most galaxies, however, are dwarfs…
Astronomers have discovered a new, enormous black hole that could change our understanding of how galaxies evolve. Holding the mass of 17 billion suns, the black hole at the centre of the NGC 1277 galaxy…
The mass of the universe’s lightest particles, neutrinos, can be more accurately measured thanks to a new mapping study…
A group of 675 stars has been discovered on the outskirts of our Milky Way galaxy, having been shot out by the black hole…
